Answer:
63.6 m^2
Step-by-step explanation:
A = (pi)r^2
r = d/2 = 9 m / 2 = 4.5 m
A = (3.142)(4.5 m)^2
A = 63.6 m^2

Find the slope of the line containing the pair of points.
(-9,- 8) and (-8,-6)
Answer:
slope = 2
Step-by-step explanation:
-8 - -6 / -9 - -8 = 2
Answer:
[tex]\frac{2}{1}[/tex] which is just 2
Step-by-step explanation:
slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
So plug the numbers in, now it should look like [tex]\frac{-6 - (-8)}{-8 - (-9)}[/tex]
-6 - (-8) = 2
-8 - (-9) = 1
So the slope is [tex]\frac{2}{1}[/tex]
6) In 3 seconds you can fill up a pool with 42 gallons of water. If this is a proportional

You work in a restaurant. Your hourly wage is $5.25. One evening you work from 5:30 to 9:30 and make $34.20 altogether. How much do you make in tips that evening?
Your answer
9514 1404 393
Answer:
$13.20
Step-by-step explanation:
Working h hours and earning t in tips, your earnings (e) are ...
e = 5.25h +t
Solving for t, we get ...
t = e - 5.25h
Filling in the given values, we have ...
t = 34.20 -5.25(4) = 34.20 -21.00 = 13.20
You made $13.20 in tips that evening.
Which of the following functions represents the graph on
the left? (Hint: Plug in your x values from the previous
slide. Do they produce f(x)=0?)
O f(x) = (x-6)(x+2)
O f(x) = (x+6) (x - 2)
9514 1404 393
Answer:
f(x) = (x -6)(x +2)
Step-by-step explanation:
The graph shows the x-intercepts are -2 and +6. The factors will be binomials such that these values make the factors zero: (x +2) and (x -6).
f(x) = (x -6)(x +2)

What is the 38th term of 459,450,441,..
Answer:
The 38th term of 459,450,441,.. will be:
[tex]a_{13}=351[/tex]
Step-by-step explanation:
Given the sequence
[tex]459,450,441,..[/tex]
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]450-459=-9,\:\quad \:441-450=-9[/tex]
so
[tex]d=-9[/tex]
The first element of the sequence is
[tex]a_1=459[/tex]
so the nth term will be
[tex]a_n=-9\left(n-1\right)+459[/tex]
[tex]a_n=-9n+468[/tex]
Putting n=38 to find the 38th term
[tex]a_n=-9n+468[/tex]
[tex]a_{13}=-9\left(13\right)+468[/tex]
[tex]a_{13}=-117+468[/tex]
[tex]a_{13}=351[/tex]
Therefore, the 38th term of 459,450,441,.. will be:
[tex]a_{13}=351[/tex]

2. After election results of 378 votes were tallied, the new student-body president won by a margin of 5 to 4. How many votes did she get?
Answer:
473 or 472, depends on how you round
Step-by-step explanation:
378/4 = 94.5
94.5 x 5 = 472.5
The number of votes she gets will be 473.
What is multiplication?It is also known as the product. If the object n is given to m times then we just simply multiply them.
2. After election results of 378 votes were tallied, the new student-body president won by a margin of 5 to 4.
Then the number of votes she gets that will be
→ 378 x 5 / 4
→ 378 x 1.25
→ 472.5 ≅ 473

The length of rectangle A is 7.4 cm and the width is 4.8 cm. The perimeter of rectangle B is 14.9 cm. How much is the perimeter of rectangle A than the perimeter of rectangle B?
Answer: 9.5 cm
Step-by-step explanation:
First we have to find the perimeter of rectangle A:
Formula for perimeter of a rectangle or square is: [tex]2(a+b)[/tex]
Putting the length and width in: [tex]2(7.4+4.8)[/tex]
Solve it to get: 24.4 cm
Subtract 14.9 from 24.4 to get 9.5 cm
