#9 Alana made $45
babysitting for 6
hours. How much do
she make per hour?
Step 1:
Start by setting it up with the divisor 6 on the left side and the dividend 45 on the right side like this:
6 ⟌ 4 5
Step 2:
The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
6 ⟌ 4 5
Step 3:
Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.
0
6 ⟌ 4 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
6 ⟌ 4 5
- 0
4
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
6 ⟌ 4 5
- 0
4 5
Step 6:
The divisor (6) goes into the bottom number (45), 7 time(s). Therefore, put 7 on top:
0 7
6 ⟌ 4 5
- 0
4 5
Step 7:
Multiply the divisor by the result in the previous step (6 x 7 = 42) and write that answer at the bottom:
0 7
6 ⟌ 4 5
- 0
4 5
4 2
Step 8:
Subtract the result in the previous step from the number written above it. (45 - 42 = 3) and write the answer at the bottom.
0 7
6 ⟌ 4 5
- 0
4 5
- 4 2
3
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 45 divided by 6 calculated using Long Division is:
7
3 Remainder

Abbie drove 325 miles in 5hrs. What is this rate in feet per second?
Answer:
4400
Step-by-step explanation:
Answer:
The rate should be 95.33 feet per second assuming that she drove with a constant speed
Step-by-step explanation:
First you divide 325 by 5. And you get 65 which is how many miles per hour she went. Then you can put it in a unit converter to change miles per hour to feet per second. And it should be 95.33 (sorry for my lack of a detailed explanation of how to transform miles per hour into feet per second)

Tonya wrote the equation below which solves for x.
x = 150 minus 6 y
Which equation is equivalent to Tonya’s equation?
x + 150 = 6 y
x + 6y = 150
2x + 3y = 75
2 x minus 3 y = 75
Given parameters:
x = 150 minus 6 y
Interpreting this gives;
minus = subtraction = -
x = 150 - 6y
Now bring the variables together;
x + 6y = 150
The option that matches with this equivalent.
The other choices are wrong;
a, x + 150 = 6 y
x - 6y = 150 wrong
c. 2x + 3y = 75 mulitply through by 2;
2(2x + 3y) = 2(75)
4x + 6y = 150 wrong
d. 2x - 3y = 75
Multiply by 2;
2(2x -3y) = 2(75)
4x - 6y = 150
Answer:
x+6y = 150 (B)

Select all of the angles that are congruent to <5 plzzz helppp
Answer:
Options A, D and F
Step-by-step explanation:
From the picture attached,
lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.
From the angles formed at the points of intersection,
∠5 ≅ ∠8 [Vertical angles]
∠5 ≅ ∠4 [Alternate interior angles]
∠5 ≅ ∠1 [Corresponding angles]
Therefore, Options A, D and F will be the correct options.
A soccer ball is punted in the air. Its height after x seconds can be modeled by a quadratic function. The soccer ball reaches its maximum height of 85 feet after 3 seconds. The ball is trapped at a height of 2.5 feet, 6 seconds after being kicked. Write a quadratic function that models the height of the soccer ball, x seconds after being kicked.
Answer:
[tex]-9.31x^2+56.26x[/tex]
Step-by-step explanation:
Let the quadratic function be:
[tex]h=ax^2+bx+c[/tex]
Where [tex]h[/tex] is the height of soccer ball and
[tex]x[/tex] is the time in seconds.
Initially, at time [tex]x=0\Rightarrow h=0[/tex]
Therefore, [tex]c=0[/tex]
Given that,
[tex]x=3, h=85\\and\\x=6, h=2.5[/tex]
Putting the values and making equations in [tex]a,b[/tex] :
[tex]85=9a+3b\\2.5=36a+6b[/tex]
By solving the above equations, we get:
[tex]a=-9.31\\ and\\b =56.26[/tex]
So, the quadratic expression is:
[tex]-9.31x^2+56.26x[/tex]
