Answer:
D
Step-by-step explanation:
simple plug and chug.
Understand that variables are already defined, x=3/4, y=15 meaning that if we plug one of the variables into an equation, we should obtain the other variable's number.
y=20x will result in y=15 when x=3/4 and vice versa.

Mr. Carter is building a circular fire pit in his backyard. The diameter of the fire pit is 6 feet and he will fill the interior with gravel covering 5/6 of the area. How much gravel will he need?
A. 23.55 sq. ft.
B. 28.26 sq. ft.
C. 94.2 sq. ft.
D. 113.04 sq. ft.
Answer:
23.55
Step-by-step explanation:
To calculate the area I did the following equation
area = 3.14 (r) (r)
area = 3.14 (3) (3)
area = 28.26
The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.
The equation for 5/6 out of 28.26 is
28.26 (5/6) = 23.55
So the final answer is (a.) 23.55 sq. ft.

Find the 10th term of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
f(1) = 8, f(n) = f(n − 1) + 15
The 10th term is
Answer:
[tex]87.[/tex]
Step-by-step explanation:
[tex]f(1) = 8, f(n) = f(n − 1) + 15 \\ The \: 10th \: term \: is \: \\ 8(10 − 1) + 15 = 72 + 15 = 87.[/tex]

Write an equation of the line that passes through the given point an satisfies the given condition.
(-3,-5); parallel to y = -4x + 1
-6 = -1/2(9) + B
-6 = 4.5 + B
-6--4.5 = B
-1.5 = B
B= -1.5
y=-1/2x - 1.5
y=-1/2(9) - 1.5
y= -4.5-1.5
y=-6

Step-by-step explanation:
Mrs. Potter was going through her Halloween candy to see which kind she would bring to school. She sorted using decimal values. .17 of her 100 pieces were black licorice. .42 were m&m's. .12 were skittles. .09 were smarties. .14 were lollipops and .06 were gum drops. Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Answer:
23%
Step-by-step explanation:
She sorted using decimal values.
We convert the decimals to percent
.17 of her 100 pieces were black licorice.
.17 = 0.17 × 100 = 17%
.42 were m&m = 0.42 × 100 = 42%
.12 were skittles. = 0.12 × 100= 12%
.09 were smarties = 0.09 × 100= 9%
.14 were lollipops = 0.14 × 100 = 14 %
.06 were gum drops. = 0.06 × 100= 6 %
Mrs. Potter decided to bring the black licorice and the gum drops to school. What percent of her candy did she bring to school?
Licorice = 17%
Gum drops = 6%
The percent of her candy that she brought to school = 17% + 6%
= 23%
The percent of her candy that she brought to school is 23%
