Answer:
7. 80 miles
8. F
Step-by-step explanation:
7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.

A = h/2(a + b)
First, multiply both sides of the equation by the reciprocal of h/2.
2A/h = a + b

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.
Addition and subtraction of two matrices can be done if they have the same dimensions. This is done by simply adding or subtracting the corresponding entries in matrices.

If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)

After how many years will an investment of $100 compounded quarterly at 6% annually be worth $450? (round to the nearest year)
Answer:
The investment will be worth $450 after 25.255 years which is about 25 years and 3 months.
Step-by-step explanation:
You have to use the following formula to calculate the number of years:
t=ln(A/P) / n(ln(1 + r/n)), where:
t=time in years
A=Accrued amount=450
P=Principal amount=100
n=number of compounding periods per time period=4
r=interest rate=0.06
Now, you can replace the values in the formula:
t=ln(450/100)/4(ln(1+(0.06/4)))
t=ln(4.5)/4(ln(1.015))
t=1.50/0.059
t=25.255
According to this, the answer is that the investment will be worth $450 after 25.255 years which is about 25 years and 3 months.

Placed the following quadratic in vertex form by completing the square and then state the coordinates of its vertex?
Y=x^2+18x-12
Answer:
y = (x + 9)² -93
vertex: (-9, -93)
Step-by-step explanation:
x² + 18x = 12
x² + 18x + 81 = 12 + 81
(x+9)² = 93
y = (x + 9)² -93
vertex: (-9, -93)
The length of a rectangular frame is 15 inches, and the width of the frame is 88 inches. What is the length of a diagonal of this frame in inches?
Answer:
about 89.27 inches
Step-by-step explanation:
This is a right triangle question
c^2 = a^2 + b^2
c^2 = 15^2 + 88^2
c^2 = 225 + 7744
c^2 = 7969
Take the square root of both sides
c = 89.2692556259
c ≈ 89.27 inches

Ann runs a day care center. Of the last 18 children to enroll at the day care center, 8 of them have been elementary school students. Considering this data, how many of the next 9 children to enroll should you expect to be elementary school students?
We would expect that 4 of the next 9 children to enroll will be elementary school students.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.
