To find out the total cost after using a coupon, you first add the prices of the items - $1.29 for chips and $0.89 for a drink, totalling $2.18. Then subtract the value of the coupon, $0.75, from this amount. The final cost would be $1.43.
Explanation:The first step in solving this problem is to add the prices of the bag of chips and the drink. According to the prices given, the chips cost $1.29 and the drink costs $0.89.
By adding these together, you will get the total cost before using the coupon. The sum of $1.29 and $0.89 equals $2.18. This is the total cost without any discounts.
Next, you need to take into account the coupon for $0.75 off the total price. Subtracting this from the initial cost, we get: $2.18 - $0.75 = $1.43.
So, the final cost of the bag of chips and the drink after using the 75 cents coupon would be $1.43.

How can you determine the coordinates of any image that is dilated with the center of dilation at the origin without graphing
Answer:
[tex](x,y)\rightarrow (kx,ky)[/tex]
Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule
[tex](x,y)\rightarrow (kx,ky)[/tex]
This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).

If a+b-c=3 what is the value of 4(a+b-3)-(a+b+3c)?
3abc
Step-by-step explanation:
Final answer:
To find the value of 4(a+b-3)-(a+b+3c) given that a+b-c=3, we simplify to 3(a + b - c) - 12. Since a + b - c equals 3, the expression simplifies to -3.
Explanation:
The question provides the equation a + b - c = 3. To find the value of the expression 4(a+b-3)-(a+b+3c), we can simplify it using the given equation.
Let's break down the steps for simplification:
First, substitute the value of a + b - c from the given equation, which is 3, into the expression we want to simplify.Then, distribute the 4 across the first set of parentheses 4(a + b - 3) which becomes 4a + 4b - 12.Now, combining this result with the second part of the expression -(a + b + 3c) gives us 4a + 4b - 12 - a - b - 3c.Grouping like terms together and simplifying gives us 3a + 3b - 3c - 12 which is equivalent to 3(a + b - c) - 12.Since a + b - c = 3, the expression becomes 3(3) - 12, which simplifies to 9 - 12.Thus, the final value of the expression is -3.General admission to The American Museum of Natural History is $19.
a. If a group of 125 students visits the museum, how much will the group’s tickets cost?
b. If the group also purchases IMAX movie tickets for an additional $4 per student, what is the new total cost of all the tickets? Write an expression that shows how you calculated the new price.
Answer:
(a) $2,375.
(b) $2,875.
Step-by-step explanation:
We have been general admission to The American Museum of Natural History is $19.
(a). To find the total cost of tickets for a group of 125 students, we will multiply 125 by $19.
[tex]\text{The total cost of tickets}=\$19\times 125[/tex]
[tex]\text{The total cost of tickets}=\$2,375[/tex]
Therefore, the total cost of 125 tickets would be $2,375.
(b). We have been given that the group also purchases IMAX movie tickets for an additional $4 per student.
The total cost of one ticket would be the cost of museum ticket plus movie ticket that is [tex]\$19+\$4=\$23[/tex].
The new total cost of 125 tickets would be 125 times $23.
[tex]\text{The new total cost of tickets}=\$23\times 125[/tex]
[tex]\text{The new total cost of tickets}=\$2,875[/tex]
Therefore, the new total cost of 125 tickets would be $2,875.

20. Acid Mixture Bill Charlson needs 10% hydrochloric acid
for a chemistry experiment. How much 5% acid should he
mix with 60 milliliters of 20% acid to obtain a 10% solution?
Answer:
120 ml
Step-by-step explanation:
Let x ml of 5% acid should mix with 60 milliliters of 20% acid to obtain a 10% solution,
Thus, the quantity of resultant mixture = ( x + 60 ) ml,
Also,
Acid in x ml 5% acid + Acid in x ml 5% acid = acid in 10% resultant solution,
5% of x + 20% of 60 = 10% of ( x + 60)
[tex]\frac{5x}{100}+\frac{20\times 60}{100}=\frac{10\times (x+60)}{100}[/tex]
[tex]5x + 1200 = 10x + 600[/tex]
[tex]5x - 10x = 600 - 1200[/tex]
[tex]-5x = -600[/tex]
[tex]\implies x = \frac{-600}{-5}=120[/tex]
Hence, 120 ml of 5% acid should be mixed.

hope this helps
Answer:
Amount of pork used was 1 pound.
Step-by-step explanation:
Mike wants to make meatloaf by adding beef and pork.
Ratio of the meat (beef and pork) is = 3 : 1
Recipe requires total amount of meat = 4 pounds
So the amount of pork used in the recipe = [tex]\frac{1}{(1+3)}\times 4[/tex]
= [tex]\frac{1}{4}\times 4[/tex]
= 1 pound
Therefore, total amount of pork used in the recipe is 1 pound.
A large western state consists of 2691 million acres of land. Approximately 65% of this pand is federally owned how to find the answer?
Answer:
Step-by-step explanation:
What you need to do is take your 65% and put it over 100% like this: 65/100
Then, you take 2691 and put it into the denominator and put x on the top like this: x/2691
Then you need to put them equal to each other and cross multiply like this 65/100=x/2691
Multiply the 2691 by 65 and x by 100
to get 100x=2691(65)
Finally, multiply the 2691 by 65 and then divide that whole thing by 100 to get x.
x will be the land in acres and your final answer.
Good luck! Hope this was clear!
65% of the total acres of the large western state is approximately 1749.15 million acres.
To find the answer:
Calculate 65% of 2691 million acres.
Divide the result by 100 to get the amount federally owned.
Therefore, the federally owned land in the large western state is approximately 1749.15 million acres.

Jackie cut a 2-yard spool into 5 equal lengths of ribbon.
a. What is the length of each ribbon in yards? Draw a tape diagram to show your thinking.
b. What is the length of each ribbon in feet? Draw a tape diagram to show your thinking.
Answer:
a. [tex]\frac{2}{5}[/tex] yard
b. 1.2 feet
Step-by-step explanation:
a. Jackie cut a 2-yard spool into 5 equal length of ribbon.
We will divide 2 yard by 5 = 2 ÷ 5 = [tex]\frac{2}{5}[/tex] yard
5 units = 2 yard
1 unit = [tex]\frac{2}{5}[/tex] yard
Check : [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{10}{5}[/tex] = 2
b. Length of each ribbon in feet
Since 1 yard = 3 feet
therefore, 2 yard = 3 × 2 = 6 feet
6 feet in to 5 equal part = 6 ÷ 5
= 1.2 feet
check : 1.2 + 1.2 + 1.2 + 1.2 + 1.2 = 6.0 feet
Each ribbon cut from a 2-yard spool into 5 equal parts will be 0.4 yards or 1.2 feet in length. Tape diagrams represent this division into equal parts.
Explanation:To determine the length of each ribbon when a 2-yard spool is cut into 5 equal lengths, you need to divide the total length by the number of pieces.
2 yards ÷ 5 = 0.4 yards for each piece.To represent this with a tape diagram, imagine a line equally divided into 5 sections, with each section representing 0.4 yards.
For the length in feet, since 1 yard equals 3 feet, we multiply the length in yards by 3.
To show this with a tape diagram, you can divide a line into 5 sections with each section representing 1.2 feet.

Step-by-step explanation:
Rounding depends on the place value, if you are rounding to the nearest thousand, look at the number in the hundred place. Is that number lower or higher than 5? If lower, the place you are rounding to stays the same, and the places below it turn to zeros. If 5 or higher, round up, add 1 to the place you are rounding to, then turn the places below to zeros.

Answer:
Since -2 is rational and √3 is irrational, the sum and difference are irrational.
Step-by-step explanation:
Given equation,
[tex]x^2 + 4x + 1 =0[/tex]
[tex]x^2 + 4x = -1[/tex]
[tex]x^2 + 4x + 4 = -1+4[/tex]

The lengths of the sides of a triangle are 3, 3, 3 square root 2 Can the triangle be a right triangle?
The triangle can be a right triangle according to the Pythagorean theorem.
Explanation:To determine if a triangle is a right triangle, we can use the Pythagorean theorem. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (hypotenuse).
In this case, the lengths of the sides are 3, 3, and 3√2. Let's calculate: (3)² + (3)² = 18 and (3√2)² = 18. Since the two values are equal, the triangle satisfies the Pythagorean theorem and can be a right triangle.

An ice cream sundae costs $1.75 plus an additional $0.35 for each topping. If the total
cost is $2.80, how many toppings did the sundae have?
Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
"The correct number of toppings on the sundae is 3.
To solve the problem, we first establish the cost of the ice cream sundae without any toppings, which is given as $1.75. We also know that each topping costs an additional $0.35. The total cost of the sundae with toppings is $2.80.
Let's denote the number of toppings as \( t \). The total cost of the sundae with toppings can be represented by the equation:
[tex]\[ \text{Total cost} = \text{Cost of sundae} + (\text{Cost per topping} \times t) \][/tex]
Substituting the known values into the equation, we get:
[tex]\[ 2.80 = 1.75 + (0.35 \times t) \][/tex]
To find the number of toppings [tex]\( t \)[/tex], we need to isolate [tex]\( t \)[/tex] on one side of the equation. We do this by subtracting the cost of the sundae from both sides of the equation:
[tex]\[ 2.80 - 1.75 = 0.35 \times t \][/tex]
[tex]\[ 1.05 = 0.35 \times t \][/tex]
Now, we divide both sides of the equation by the cost per topping to solve for [tex]\( t \)[/tex]:
[tex]\[ \frac{1.05}{0.35} = t \][/tex]
[tex]\[ t = 3 \][/tex]
