Δ GHI and Δ JKL are congruents because:
1. Their sides GH and JK are equal (9 units = 9 units)
2. Their included angles ∠G and ∠J are equal (62° = 62°)
3. Their sides GI and JL are equal (17 units = 17 units)
Now, we can conclude that Δ GHI ≅ Δ JKL by SAS postulate.
If the probability of surviving a head on car accident at 55 mph is 0.097, then what is the probability of not surviving
The probability of not surviving a head-on car accident is: 0.903
Step-by-step explanation:
The probabilities of occurrence and non-occurrence of an event add up to one.
If p is the probability that an even will happen and q is the probability that it will not happen
Then
[tex]p+q=1[/tex]
Here,
Probability of surviving = p = 0.097
Probability of not surviving = q = ?
[tex]0.097 + q = 1\\q = 1 - 0.097\\q = 0.903[/tex]
The probability of not surviving a head-on car accident is: 0.903

A used-boat dealership buys a boat for $2900 and then sells it for $4500. What is the percent increase?(Round to the nearest whole number as needed.)
Answer:
55%
Step-by-step explanation:
We have to divide the new price by the original price
4500/2900 = ca. 1.5517
Take away 100% from this answer and we get 0.5517 over the original price
This is the same as 55.17% can be rounded to 55%
To find the percent increase in the boat's price, subtract the original price from the selling price, divide by the original price, then multiply by 100 and round to the nearest whole number. The calculation shows about a 55% increase from the original price of $2900 to the selling price of $4500.
Explanation:To calculate the percent increase, you would subtract the original price of the boat from the selling price and then divide by the original price to get the fraction of the increase. Finally, you multiply this fraction by 100 to convert it to a percentage. Using the given numbers: The original price is $2900, and the selling price is $4500.
Subtract the original price from the selling price: $4500 - $2900 = $1600Divide the increase by the original price: $1600 / $2900 ≈ 0.5517241379Multiply by 100 to convert to a percentage: 0.5517241379 × 100 ≈ 55.17%When you round this to the nearest whole number, you get a percent increase of 55%.

what value of k makes the factor (x+3) a factor of the function f(x)=3x^3-2x+k?
Final answer:
To find the value of k that makes (x+3) a factor of the function f(x)=3x^3-2x+k, substitute x=-3 into the equation, leading to the solution k=75.
Explanation:
The question asks for the value of k that makes (x+3) a factor of the function f(x)=3x³-2x+k. To solve this, we use the fact that if (x+3) is a factor of f(x), then f(-3)=0. Therefore, we substitute x=-3 into the equation and solve for k.
Substituting x=-3 into f(x)=3x³-2x+k gives:
f(-3) = 3(-3)³- 2(-3) + k = -81 + 6 + k
Since f(-3)=0, we have -75 + k = 0
Thus, k = 75
This computation shows that the value of k that makes (x+3) a factor of the given function is 75.
At the movie theatre child admission is $6.30 and adult is $9.90 on Monday, 138 tickets were sold for a total sales of $1053.00. How many tickets were sold that day
Answer: 87 children and 51 adult
Step-by-step explanation:
Let x be child admission and let y be adult admission.
We know that x+y=138 based on the fact that 138 tickets were sold.
We also know that 6.3x+9.9y=1053 based on the information.
Let y=138-x
Then, 6.3x+9.9(138-x)=1053
6.3x+1366.2-9.9x=1053
-3.6x+1366.2=1053
-3.6x=-313.2
x=87
138-87=y=51
87 children's and 51 adult tickets were sold.

Answer:
x = 21 degrees
y = 66 degrees
Step-by-step explanation:
Supplementary angles sum 180 degrees and complementary angles sum 90 degrees.
The first two upper angles are supplementary since they complete half a turn of a circle.
The relation is
(3x+5)+(6x-14)=180.
Joining like terms
9x-9=180
Dividing by 9
x - 1= 20 =>
x = 21 degrees
The first and the last angle are the same because they are formed by two parallel lines to a common side, so
3x-5=y-8 or
y=3x+3 = 63+3 =>
y = 66 degrees

Answer:
A. 5Step-by-step explanation:
The formula of a distance between two points:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have two points (-4, -4) and (-1, 0).
Substitute:
[tex]d=\sqrt{(-1-(-4))^2+(0-(-4))^2}=\sqrt{(-1+4)^2+(0+4)^2}\\\\=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5[/tex]
Which of the following point-slope form equations could be produced with the points (2, -6) and (4, -3)?
y - 6 = 3/2(x + 2)
y - 6 = 3/2(x - 2)
y + 6 = 3/2(x - 2)
y + 6 = -3/2(x + 2)
Answer:
C) y+6=3/2(x-2)
Step-by-step explanation:
y-y1=m(x-x1)
m=slope & (x1, y1) is a point on the line
m=(y2-y1)/(x2-x1)
m=(-3-(-6))/(4-2)
m=(-3+6)/2
m=3/2
y-(-6)=3/2(x-2)
y+6=3/2(x-2)
Option 3
The point slope form of the given points (2, -6) and (4, -3) is [tex]y+6=\frac{3}{2}(x-2)[/tex]
Solution:Given that two points are (2, -6) and (4, -3)
We have to find the point slope form
The point-slope of the line is given as:
[tex]y - y_1 = m(x - x_1)[/tex]
Where m is the slope of the given line.
So now to write the given points in point intercept form we need to find the slope, m
The slope of line is given as:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]\text { Here } x_{1}=2 ; y_{1}=-6 ; x_{2}=4 ; y_{2}=-3[/tex]
Plugging in the values, we get
[tex]m=\frac{-3-(-6)}{4-2}=\frac{3}{2}[/tex]
So, the slope of the given line is [tex]\frac{3}{2}[/tex]
Now, we need to find the point slope form. For that purpose we can use either of the points, but since in the answer options they have used the 1st point we will do so too.
Therefore, the point slope form is:
[tex]\begin{array}{l}{y-(-6)=\frac{3}{2}(x-2)} \\\\ {y+6=\frac{3}{2}(x-2)}\end{array}[/tex]
From the given options we can see that the correct answer is option 3.

How many pounds of peanuts that sell for $1.5 per pound should be mixed with cashews that sell for $4.5 per pound so that a 10-pound mixture is obtained that will sell for $3.00 per pound?
5 pounds of peanuts should be mixed with cashews
Step-by-step explanation:
The given is:
The price of one pound of peanut is $1.5
The price of one pound of cashew is $4.5
10-pound mixture is obtained that will sell for $3.00 per pound
We need to find how many pounds of peanuts should be mixed with cashews
Assume that x represents the number of pound of peanuts, and y represents the number of pounds of the cashews
∵ x pounds of peanuts should be mixed with y pounds of cashews
∵ The mixture obtained is 10 pounds
∴ x + y = 10 ⇒ (1)
∵ The price of each pound of peanut = $1.5
∵ The price of each pound of cashew = $4.5
∴ The selling price of the mixture = 1.5x + 4.5y
∵ The selling price of one pound of mixture = $3
∵ The mixture is 10 pounds
∴ The selling price of the mixture = 3 × 10 = 30
- Equate the two expressions of the selling price of the mixture
∴ 1.5x + 4.5y = 30 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -4.5 to eliminate y
∵ -4.5x - 4.5y = -45 ⇒ (3)
- Add equations (2) and (3)
∴ -3x = -15
- Divide both sides by -3
∴ x = 5
∵ x represents the number of pounds of peanuts
∴ The number of pound of peanuts is 5
5 pounds of peanuts should be mixed with cashews

Please help ASAP. Quadrilateral CDEF is inscribed in circle A. If the m∠C = 7x + 11° and m∠E = 7x + 1°, what is the measure of ∠E?
A) 95
B) 99
C) 81
D) 85
Answer:
The answer is D
Step-by-step explanation:
∠C + ∠E = 180°(consecutive angles)
7x +11° + 7x + 1° = 180°
14x + 12° = 180°
14x = 168°
x = 12°
∠E = 7x + 1°
= 7(12°) + 1
= 85°
The measure of ∠E is 85 degrees
How to determine the measure of E?To calculate the measure of E, we start by calculating the value of x using:
∠C + ∠E = 180° (consecutive angles of cyclic quadrilateral)
So, we have:
7x +11° + 7x + 1° = 180°
Evaluate the like terms
14x + 12° = 180°
Subtract 12 from both sides
14x = 168°
Divide both sides by 14
x = 12°
Recall that:
∠E = 7x + 1°
Substitute 12 for x
∠E = 7(12°) + 1
Evaluate
∠E = 85°
Hence, the measure of ∠E is 85 degrees

Step-by-step explanation:
A fact family includes related multiplication and division facts. For the numbers 2, 4, and 8, the facts are 2 x 4 = 8, 4 x 2 = 8, 8 ÷ 4 = 2, and 8 ÷ 2 = 4. This demonstrates the relationship between multiplication and division.
Fact Family for Multiplication and Division
A fact family in mathematics is a group of related math facts involving the same numbers. For the numbers 2, 4, and 8, the fact family includes both multiplication and division facts. Here are the four members of this fact family:
2 x 4 = 8
4 x 2 = 8
8 ÷ 4 = 2
8 ÷ 2 = 4

Will the point (2, 6) be on the graph of y = 3x?
A. No, because an equation does not have points.
B. Yes, because x = 6 and y = 2 is a solution to the equation.
C. Yes, because x = 2 and y = 6 is a solution to the equation.
D. No, because x = 6 and y = 2 does not make the equation true.
Answer:
Yes, because x = 2 and y = 6 is a solution to the equation.
The point (2, 6) does lie on the graph of the equation y = 3x because when you substitute x = 2 and y = 6 into the equation, it holds true (6=3*2). Hence, yes, because x = 2 and y = 6 is a solution to the equation.
Explanation:To determine if the point (2, 6) is on the graph of y = 3x, you would need to substitute the values of x and y into the equation and see if it holds true. In this case, if we substitute x = 2 and y = 6, we get 6 = 3*2, which simplifies to 6 = 6. This shows that the equation is true, therefore, the point (2, 6) lies on the graph of y = 3x. So the correct answer is C: Yes, because x = 2 and y = 6 is a solution to the equation.

find the slope of a line that passes through (6,8) and (1,18)
Answer:
m(the slope) = -2
Step-by-step explanation:
First, you want to use the slope formula. This can be written as (Y[subscript2]-Y[subscript1])/(X[subscript2]-X[subscript1]). This may seem a bit confusing but I hope it will make sense to you. The subscripts basically mean which Y value or X value you are taking. In this case, you could rewrite the equation as this: (18-8)/(1-6). The 18 is the Y value of the second point, so it is Y[subscript2]. Now all you need to do is simplify the equation.
