Your science teacher has a 1: 200 scale model of the space shuttle atlantis. which of the proportions can you use to find the actual length x of atlantis? explain a- 1/200 = 19.5/x b- 1/200 = x/19.5 c-200/19.5=x/1 d-x/200=1/19.5

B. (1/200 = x/19.5)

EXPLANATION

Space shuttle Atlantis model scale 1:200

Length of Atlantis on model = 19.5

The actual length of Atlantis = x

Find x

Scale = 1:200; in decimal = 1/200

When length on model = 1

Actual length = 200

When actual length = x

Length on model = 19.5

Scale = x:19.5 ; in decimal = x/19.5

Equating both scales,

1/200 = x/19.5 (Option B)

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
