Answer:
20 feet
Step-by-step explanation:
Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
We solve this using proportion of
Height/ Shadow
= 5/8 = x/32
Cross Multiply
8x = 5 × 32
x = 5 × 32/8
x = 20 feet
The height of the tree is 20 feet
Answer:
Step-by-step explanation:
We have:
To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:
Divide both sides by 2:
Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:
Therefore, our solutions are:
