Step-by-step explanation:
b.) 8/7≈ 1.1
Final.) and then using the exponential decay formula, 18.1 will be left after
The answer is
B) 2n - 5
because it's -5 than twice the width (2n)
A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
If 4 lbs of potatoes cost 6.78...then 1 lbs of potatoes cost 6.78/4 = 1.695...rounds to 1.70 per lb
Answer:
A.
Step-by-step explanation:
y = mx + c
m = y - y¹ / x - x¹
= 4-3 / 4-2
= 1/2
using (4,4)
4 = 1/2 × 4 + c
4 = 2 + c
c = 2
equ..=
y = 1/2x + c
