Answer:
V =41.41³
A = 94.41²
----
V =225.16³
SA =283.25²
----
V = 64³
SA =113.32²
----
V =433.33³
SA = 378.57²
Step-by-step explanation:
Picture 2 = a = 1/2 base = 3.5 x 3.5 = 12.25 b= 5 x 5 = 25
c²= a² + b² = 3.5² + 5²
c ²= √12.25 + √25
c ²= √ 37.5 = 6.12372435696
c ² = 6.1237 missing side
Picture 1 + 2 formula SA = bh + (s1 + s2 + s3)H
V = V= 1/2 b x h h x SA
Picture 3 + 4 formula SA= a²+ 2a a² / 4 + h² V= a² h/3
i dont know this one sorry
The number of years past when Alan was twice Vanessa's age is 14 years.
Current ages :
- Alan = 30 years
- Vanessa = 22 years
<u>We can set up an equation where, x = number of years when Alan was 2 times Vanessa's age thus</u> :
30 - x = 2(22 - x)
30 - x = 44 - 2x
Collect like terms
-x + 2x = 44 - 30
x = 14
Therefore, 14 years ago, Alan's age was twice Vanessa's age.

Looking at the picture it is just a triangle with a hypotenuse of 10 (the ladder) and the bottom side of 6 (distance from the ladder to tree). All you have to do now is the Pythagorean theorem: a^2 + b^2 = c^2
10^2 - 6^2 = b^2
100 - 36 = b^2
64 = B^2 now square root both sides.
