Melissa’s family is driving out of state to her grandmother’s house. They know that it takes 20 gallons of gas to get there, and the cost of three gallons of gasoline is $10.50. How much should the family budget to make the one-way trip?
For this case we have that the cost for each gallon of gasoline is given by:
[tex]\frac {10.5} {3} = 3.5[/tex]
We have that the total number of gallons is equal to 20.
As the family is going to make only one trip then, the total cost is given by:
[tex]20 * 3.5 = 70[/tex]
Answer:
the family should budget 70 $ to make the one-way trip

Solve x2 - 8x = 3 by completing the square. Which is the solution set
[4 - 19,4 + /19}
{4 - V11, 4 + /11)
{4 - V8, 4 + }
[4 - V3, 4 + (3)
Answer:
4\pm\sqrt{19}
Step-by-step explanation:
Move everything to left side
[tex]x^{2} -8x -3 =0[/tex]
Now to solve this square equation we need to find Descriminant
[tex]D=b^{2} -4ac=64+12=76[/tex]
As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula
[tex]x_{1,2}=\frac{-b\pm\sqrt{D}}{2a} =\frac{8\pm2\sqrt{19}}{2}=4\pm\sqrt{19}[/tex]
Completing the square in mathematics is a technique used to solve quadratic equations by transforming them into a perfect square trinomial form. It helps in finding the roots of the equation more efficiently.
Completing the square involves transforming a quadratic equation into a perfect square trinomial form to solve it. In the case of x^2 - 8x = 3, the steps would include halving the coefficient of x, squaring that value, and adding/subtracting it to both sides of the equation to complete the square.
The solution set for the equation x^2 - 8x = 3 would be {4 + √19, 4 - √19}, as completing the square helps in finding the roots of the quadratic equation.
Completing the square is a helpful technique in mathematics for solving quadratic equations more easily and efficiently.

The study of proportions in triangles involves understanding similar triangles' corresponding side ratios and how area scales with linear dimensions. The ratios help determine unknown lengths and compare triangles, and the square of the scale factor relates to how area changes.
Explanation:Understanding Proportions in Triangles
Proportions play a crucial role in the study of triangles, particularly when dealing with similar triangles. Similar triangles have corresponding sides that are in proportion and this concept can be applied in various problems to find unknown lengths or to compare triangles. For instance, if two triangles are similar, then the ratio of their corresponding sides are equal. This can be denoted as a₁ = A₁/A2 or a3 = A3/A2, where A1, A2, and A3 represent the lengths of the sides in one triangle, and a1 and a3 are the proportional sides in the other.
Area scaling is another important concept derived from proportions. If a triangle's sides are scaled by a factor, its area scales by the square of that factor. For example, if the sides of one triangle are twice as long as the sides of a similar triangle, the area of the larger triangle is four times greater, since 2 squared equals 4. This principle can be easily demonstrated by cutting the larger triangle into four smaller triangles identical to the original smaller one, showing that the larger triangle has four times more area as illustrated in fig. (b).
In summary, proportions are crucial when working with similar triangles and understanding how changes in linear dimensions affect the area of a triangle. When comparing triangles, the ratios of corresponding sides and areas can provide valuable insights and are foundational in various applications within geometry.

The vertices of the triangle are A (3,5), B (6, 1), and C(5,9) is dilated using a scale factor 2. Find the coordinates of the
dilated triangle.
Answer:
2nd choice
Step-by-step explanation:
How you have to is multiply the coordinates by 2 since the scale factor you want to dilate image at is at 2.
That is the pre-image is (x,y) and the image is (2x,2y) per each point.
A(3,5) becomes A'(3*2,5*2)=A'(6,10)
B(6,1) becomes B'(6*2,1*2)=B'(12,2)
C(5,9) becomes C'(5*2,9*2)=C'(10,18)
So 2nd choice.
The coordinates of the dilated triangle are (6,10) , (12,2) and (10,18)
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures
How to find the coordinates of a dilated triangle?To find the final coordinates we need to multiply the initial coordinates by the scale factor which is 2.So for the coordinate A(3, 5), the coordinate of the dilated triangleA' = (3 x 2, 5 x 2) = (6, 10)
For the coordinate B (6, 1), the coordinate of the dilated triangleB' = (6 x 2, 1x 2) = (12,2)
Similarly C' will be (10 , 18)
So the coordinates of the dilated triangle are (6,10) , (12,2) and (10,18)
So option B is correct.

Match each sequence to its appropriate recursively defined function
Answer:
f(1) = -24; f(n) = 4·f(n-1)f(1) = 13; f(n) = f(n-1) + 26f(1) = 28; f(n) = -4·f(n-1)Step-by-step explanation:
Identify the first term of the sequence. First terms are -24, 13, 28. Find the matching f(1). There are two choices for each first term.
Then determine the relation of each term to the previous term. In two of the sequences, a factor of 4 is involved. For the sequence starting with -24, the adjacent terms have the same sign, so the factor is +4. For the sequence starting with 28, adjacent terms have alternating signs, so the factor is -4.
For the sequence starting with 13, the second term is 3 times the first, but it is also 26 added to the first. You have to look at the next term to see if the sequence is geometric with a ratio of 3, or arithmetic with a difference of 26. The latter is the case, so the recursive definition will involve addition, not multiplication.
The recursively defined functions are shown above in the order of the given sequences.

Louise mowed a neighbor's yard to earn \$25$25dollar sign, 25. She mowed a few more yards and earned an additional \$75$75dollar sign, 75. She continued to mow all of the yards each week for a total of 555 weeks, earning money at the same rate. At the end of the 555 weeks, she spent \$250$250dollar sign, 250.
Write a numerical expression with parentheses for the amount of money Louise has left.
Answer:
She has 250 dollars left
Step-by-step explanation:
The first lawn she gained 25 dollars
+25
Then she gained 75 dollars
+25 +75=100
She mowed lawns for 5 weeks making the same amount 5 weeks at 100 dollars
5*100 = 500
She earned a total of 500 dollars
She spent 250 dollars
500-250 = 250
She has 250 dollars left
A paint box contains 12 bottles of different colors. If we choose equal quantities of 3 different colors at random, how many color combinations are possible? A. 479,001,600 B. 1,320 C. 220 D. 36
Answer:
C
Step-by-step explanation:
You are choosing 3 from a total of 12. Order does not matter. So you are working with combinations. The answer symbolically is
12C3
12C3 = 12!/(9!3!)
12C3 = 12 * 11 * 10 * 9!/(9! 3!)
12C3 = 12 * 11 * 10/6
12C3 = 2 * 11 * 10
12C3 = 220
========================================
We have 12 choices for the first selection, 11 for the second, and 10 for the third. There are 12*11*10 = 1320 permutations. If your teacher was asking about permutations, then you would be done at this point. However, your teacher is asking about combinations. With combinations, order does not matter.
For any group of 3 items, there are 3! = 3*2*1 = 6 ways to arrange this group. This means that we must divide 1320 over 6 to correct for the fact that we overcounted by a factor of 6
In this case,
number of combinations = (number of permutations)/6
number of combinations = 1320/6
number of combinations = 220
More generally, I'm using the connection that
nCr = (nPr)/(r!)
A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down. Which rule describes the translation?
Answer:
Because the translation is 4 units towards the right, it will be x + 4
and because it is 3 units down, it will be y - 3
(x,y) → (x + 4, y - 3)
Step-by-step explanation:
Final answer:
The translation of a triangle 4 units right and 3 units down is described by the rule (x, y) → (x+4, y-3).
Explanation:
The rule that describes the translation of a triangle 4 units to the right and 3 units down in the coordinate plane can be represented as (x, y) → (x+4, y-3). This represents a translation where each point (x, y) of the triangle is moved to a new point obtained by adding 4 to the x-coordinate and subtracting 3 from the y-coordinate. In terms of transformation geometry, this rule effectively shifts the entire shape without rotating, resizing, or otherwise distorting it.

A single card is drawn from a deck of 52 cards, find the following
probabilities:
a. result is a queen
b. result is a queen result is a face card
c. result is a heart
d. result is a heart | result is a red card
e. result is a heart result is a black card
f. result is a heart result is not a diamond
Answer:
a. 1/13
b. 1/78
c. 1/4
d. 1/12
e. 1/6
f. 1/4
Step-by-step explanation:
First, lets write some basic data
There are total 52 cards.26 cards are red and 26 cards are blackOut of 26 red cards; 13 cards are of diamond and 13 cards are of heartOut of 26 black cards; 13 cards are of spade and 13 cards are of clubsIn spade, clubs, heart and diamond there is one card of ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, King, Queen, Jacka. result is a queen
Each set has one queen; 1 of spade, 1 of clubs, 1 of heart, 1 of heart
There are total 4 queens
Total number of cards is 52
Probability = Number of favourable outcomes/total number of outcomes
Probability = 4/52
Probability = 1/13
b. result is a queen result is a face card
From my understanding, this question is result is a queen given that result is a face card.
Queen: 4 cards
Face card means King, Queen and Jack
Each set has one King, one Queen and one Jack
There are total 4 sets
Therefore, there are 4 Kings, 4 Queens and 4 Jacks
Face cards: 12-4 (because 4 queens have already been taken out) = 8
Total number of cards: 52-4 (because 4 queens have already been taken out) = 48
Probability (A|B) = P(A) * P(A|B)
P(A) = result is a queen = 4/52 = 1/13
P(A|B) = result is a face card = 8/48 = 1/6
Probability (A|B) = P(A) * P(A|B)
Probability (A|B) = 1/13 * 1/6
Probability (A|B) = 1/78 or 0.01282
c. result is a heart
Out of the 52 cards, there are 26 red cards and out of the 26 red cards, there are 13 cards of heart
Heart = 13 cards
Total number of cards = 52 cards
Probability = Number of favourable outcomes/total number of outcomes
Probability = 13/52
Probability = 1/4
d. result is a heart | result is a red card
Result is a heart = P(A) = 13/52 = 1/4
Result is a red card=26/52 Total number of red cards is 26 but 13 cards (heart) are already taken out so 13 will be subtracted from the numerator and denominator
= 13/39 = 1/3
Result is a heart given that result is a red card P(A|B) = 1/3
Probability (A|B) = P(A) * P(A|B)
Probability (A|B) = 1/4 * 1/3
Probability (A|B) = 1/12
e. result is a heart result is a black card
Result is a heart = P(A) = 13/52 = 1/4
Result is a black card=26/52 Total number of cards is 52 but 13 cards (heart) are already taken out so 13 will be subtracted from the denominator
= 26/39 = 2/3
Result is a heart given that result is a black card P(A|B) = 2/3
Probability (A|B) = P(A) * P(A|B)
Probability (A|B) = 1/4 * 2/3 = 1/6
f. result is a heart result is not a diamond
Result is a heart = P(A) = 13/52 = 1/4
Result is not a diamond = there are 13 diamonds in a deck so cards that are not diamond are 52-13 = 39
Total cards = 52 - 13 (because hearts are already taken out) = 39
= 39/39 = 1
Probability (A|B) = P(A) * P(A|B)
Probability (A|B) = 1/4 * 1 = 1/4
!!
The probabilities of the given result in each subpart for deck of 52 cards can be given as following:
a. 1/13
b. 1/3
c. 1/4
d. 1/2
e. 0
f. 1/3
Following are the basics points need to know to solve this question:
There are total 52 cards.26 cards are red and 26 cards are black.Out of 26 red cards; 13 cards are of diamond and 13 cards are of heart.Out of 26 black cards; 13 cards are of spade and 13 cards are of clubs.In spade, clubs, heart and diamond there is one card of ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, King, Queen, Jack.a. Probability that the result is a queen
There are 4 queens in a standard deck of 52 cards. So the probability:
[tex]P(Queen) = \frac{ Number \ of \ Queens }{Total \ Cards} = \frac{4}{52} = \frac{1}{13}[/tex]
b. Probability that the result is a queen given the result is a face card
There are 12 face cards in a deck (3 face cards each for 4 suits: Jack, Queen, King). So, conditional probability:
[tex]P(Queen | Face Card) = \frac{ Number \ of \ Queens }{Total \ Face \ Cards} = \frac{4}{12} = \frac{1}{3}[/tex]
c. Probability that the result is a heart
There are 13 hearts in a deck. So the probability:
[tex]P(Heart) = \frac{ Number \ of \ Hearts }{Total \ Cards} = \frac{13}{52} = \frac{1}{4}[/tex]
d. Probability that the result is a heart given the result is a red card
Red cards consist of hearts and diamonds. There are 26 red cards, and half of them are hearts. So, conditional probability:
[tex]P(Heart | Red \ Card) = \frac{ Number \ of \ Hearts }{Number \ of \ Red \ Hearts} = \frac{13}{26} = \frac{1}{2}[/tex]
e. Probability that the result is a heart given the result is a black card
Black cards consist of spades and clubs. There are no hearts in black cards. So:
[tex]P(Heart | Black \ Card) = 0[/tex]
f. Probability that the result is a heart given the result is not a diamond
If the card drawn is not a diamond, it must be either a heart, club, or spade. There are 39 such cards. So:
[tex]P(Heart |Not \ a \ Diamond) = \frac{ Number \ of \ Hearts }{Number \ of \ Non-Diamond \ Cards} = \frac{13}{39} = \frac{1}{3}[/tex]

Melody lives due south of her cousins house and 40 miles due west of her grandparents house. One day she drove to her cousins house in a straight line from her grandparents house. How far did she drive?
Final answer:
Melody drove approximately 56.57 miles in total on her trip from her grandparents' house to her cousin's house by traveling in a straight line.
Explanation:
Melody drove a distance of 40 miles in a straight line from her grandparents house to her cousin's house. To find the total distance she drove, we can use the Pythagorean theorem as she traveled in a right-angled triangle.
Distance due south = 40 miles
Distance due west = 40 miles
Total distance driven = √(40² + 40²)
Total distance driven = √(1600 + 1600) = √3200
Total distance driven ≈ 56.57 miles
If 5 cans of baked beans cost $2.85, how
many cans of baked beans can be bought
for $19.38?
Answer:
34 cans. If you set it up as ratios (5/2.85 = x/19.38), make the number of cans you need to know "x" and solve for x.
Final answer:
To determine how many cans of baked beans can be bought for $19.38, divide $19.38 by the cost of each can, which is found by dividing the total cost of 5 cans by 5. The result is that you can buy 34 cans of baked beans for $19.38.
Explanation:
To find out how many cans of baked beans can be bought for $19.38, we need to determine the cost of each can. Given that 5 cans of baked beans cost $2.85, we can divide the total cost by the number of cans to find the cost of each can: $2.85 ÷ 5 = $0.57 per can.
Next, we divide the amount of money we have, $19.38, by the cost of each can to find the number of cans we can buy: $19.38 ÷ $0.57 = 34 cans.
So, for $19.38, we can buy 34 cans of baked beans.

Which table represents a nonlinear function?
Answer:
C.
Step-by-step explanation:
If equal changes in x result in equal changes in y, then the function is linear.
A. Are the changes from (2, 4) to (4, 1) and from (4, 1) to (6, 11) equal?
The change from (2, 4) to (4, 1):
When x changes from 2 to 4, the change is 4 - 2 = 2.
y changes from -9 to 1; the change is 1 - (-9) = 10
The change from (4, 1) to (6, 11):
When x changes from 4 to 6, the change is 6 - 4 = 2.
y changes from 1 to 11; the change is 11 - 1 = 10
For a change in x of 2, the change in y is 10 in both cases. This function is linear.
B. Are the changes from (2, -14) to (4, -16) and from (4, -16) to (6, -18) equal?
The change from (2, -14) to (4, -16):
When x changes from 2 to 4, the change is 4 - 2 = 2.
y changes from -14 to -16; the change is -16 - (-14) = -2
The change from (4, -16) to (6, -18):
When x changes from 4 to 6, the change is 6 - 4 = 2.
y changes from -16 to -18; the change is -18 - (-16) = -2
For a change in x of 2, the change in y is -2 in both cases. This function is linear.
C. Are the changes from (2, 0) to (4, 6) and from (4, 6) to (6, 16) equal?
The change from (2, 0) to (4, 6):
When x changes from 2 to 4, the change is 4 - 2 = 2.
y changes from 0 to 6; the change is 6 - 0 = 6
The change from (4, 6) to (6, 16):
When x changes from 4 to 6, the change is 6 - 4 = 2.
y changes from 6 to 16; the change is 16 - 6 = 10
For a change in x of 2, the change in y is 6 in one case and 10 in the other case. This function is not linear.
D. Are the changes from (2, -9) to (4, -6) and from (4, -6) to (6, -3) equal?
The change from (2, -9) to (4, -6):
When x changes from 2 to 4, the change is 4 - 2 = 2.
y changes from -9 to -6; the change is - 9 - (-6) = -3
The change from (4, -6) to (6, -3):
When x changes from 4 to 6, the change is 6 - 4 = 2.
y changes from -6 to -3; the change is -6 - (-3) = -3
For a change in x of 2, the change in y is -3 in both cases. This function is linear.

8m+4n+7m−2n
What is the answer?
a) 17mn
b) m + 2n
c) 15m + 2n
d) 15m + 6n
Answer:
c) 15m + 2n
Step-by-step explanation:
8m+4n+7m−2n
Combine like terms
8m+7m +4n−2n
15m +2n
8m + 4n + 7m - 2n
You wouldn't have any trouble with this at all if it said
8monkeys + 4nuts + 7monkeys - 2nuts
First you would look through it to see how many monkeys there are all together. You would addum up.
8monkeys + 7monkeys = 15 monkeys
Then you would look through it to see how many nuts there are all together, and you would addum up.
4nuts - 2nuts = 2 nuts
Then you would write these results on one line:
15monkeys + 2nuts .
Why should it be a big tough deal when there's just a bunch of m's and n's ?
First, just look through it to see how many m's there are all together, and addum up:
8 m's + 7 m's = 15 m's
Then just look through it to see how many n's there are all together, and addum up:
4 n's - 2 n's = 2 n's
Then write these results on one line:
15 m + 2 n .
That's choice-c .
Mrs. Vanwhy made a two-way table to show which students made honor roll and which students study a foreign language.
Which is the best two-way table for Mrs. Vanwhy to organize her data?
Answer:
2
Step-by-step explanation:
did it on edge
Option (B) Column 1 has entries honor roll, foreign language, total. Column 2 is labeled not on honor roll. Column 3 is labeled no foreign language. Column 4 is labeled total is the correct answer.
What is table of values?A table of values is a set of ordered pairs usually resulting from substituting numbers into an equation (relation). By using this variable within the equation or in the other function, the value of the other variable or the missing number in the equation can be found easily.
For the given situation,
The diagram shows the two-way table.
Mrs. Vanwhy made a two-way table to show which students made honor roll and which students study a foreign language.
From the data, the table that shows all the required data for Mrs. Vanwhy to organize her data should consist of honor roll, foreign language, not on honor roll, no foreign language.
Hence we can conclude that option (B) Column 1 has entries honor roll, foreign language, total. Column 2 is labeled not on honor roll. Column 3 is labeled no foreign language. Column 4 is labeled total is the correct answer.

The equation tan(55°)= 15/b
can be used to find the length of AC
What is the length of Ac? Round to the nearest tenth.
Answer:
10.5
Step-by-step explanation:
tan(55°)=15/b
b=15/tan(55°)
=10.5
Answer:
AC ≈ 10.5
Step-by-step explanation:
tan55° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{b}[/tex]
Multiply both sides by b
b × tan55° = 15 ( divide both sides by tan55° )
b = [tex]\frac{15}{tan55}[/tex] ≈ 10.5
Hence b = AC ≈ 10.5 ( to the nearest tenth )
