4. The circumference of (distance around) a circle is n times the diameter, or C = nd. A side of the square is the diameter of each half circle.
In your answer to question 1, you gave the number of complete circles
included in the track. Use this answer and C = nd to find the approximate
length of the circular part of the track to the nearest tenth of a foot. Use
3.14 for I and show your work.
Write your answer in the space below.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

i think the answer is b.

step-by-step explanation:

not 100% sure though.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
