Answer:
6
Step-by-step explanation:
3+3 maybe :) .
(length of tree's shadow)/(height of tree) = (length of person's shadow)/(person's height)
24/x = 8/5
24*5 = x*8
120 = 8x
8x = 120
8x/8 = 120/8
x = 15
The tree is 15 feet tall
Answer:
x=0
Step-by-step explanation:
I must assume that your goal is to "solve for x." State your goal explicitly each time you post a problem.
Combining like terms, we get 4x = 0, so that x = 0.
Check: Is 5(0) - 13 = 0 - 13 true? YES
Steps:
Find the 2D area of the two triangles:
- multiply 6 x 8 and divide it by 2 (this is the bottom triangle.)
** don't use 10 because it is the hypotenuse.
- 6 x 8 = 48
- 48 / 2 = 24 (you will need to use this twice since there are 2 triangles)
Now find the 2D area of the three rectangles
- first you have to convert 4 yd to feet.
**1 yd = 3 ft
~4 yd = 12 ft
-now multiply 12 x 10
- 12 x 10 = 120ft (use this 3 times since there are 3 rectangles)
Now add all those together:
120 + 120 + 120 + 24 + 24 = 408
So this question is asking whether 9/50 or 1/5 is more. To do this we need to make 1/5 have a denominator of 50. So, we multiply the numerator and the denominator by 10.
1/5 * 10/10 = 10/50
Because 9/50 is less than 10/50, more kids want to see in the future.
