Answer:
16.6 in³
Step-by-step explanation:
Given the ratio of similarity = 2 : 3, then
the ratio of volumes = 2³ : 3³ = 8 : 27
let the volume of prism A be x then by proportion
=
( cross- multiply )
27x = 448 ( divide both sides by 27 )
x = 448 ÷ 27 ≈ 16.6 ( to 1 dec. place )
Prism A has a volume of approx 16.6 in³
T=0.33c+32
0.33c=0.33×c: cost of the additional cards
A
Because 0.8 is equaled to 8/10 which is greater than all
Answer:
20d
Step-by-step explanation:
its my guess, several weeks not seven so you dont know how many weeks so we use the variable d. $20 a week. multiply the $20 by the amount of weeks you get 20d
Y = mx
We just need to find the slope:
y2 - y1 / x2 -x1 = -4 - 4 / 1 - - 1 = -8/2 = -4/1 = -4
so: y = -4x
Hope that helps! :)
