Answer:
C
Step-by-step explanation:
It's stated that EFI is dilated by a scale factor of 1/3.
Dilating gives the following
FH = 1/3×FE
FG = 1/3×FI
HG = 1/3×EI
Sense ΔEFI is reflected over a line FG/FH = (1/3×FI)/(1/3×FE) = FI/FE
Notice that the following shows triangle similarity, meaning ΔEFI ~ ΔHFG.
The only answer choice that shows this would be FE/3 = FH, FI/3 = FH, and
EI/3 =HG ΔEFI ~ ΔHFG.

Answer: 11.36 cm</h3>
Work Shown:
n = number of children = 7
a = average finger length of the children = 9.4 cm
m = number of adults = 4
b = average finger length of the adults = 14.8 cm
c = weighted average finger length of all 11 people
c = (n*a + m*b)/(n + m)
c = (7*9.4 + 4*14.8)/(7+4)
c = 11.3636363636363 approximately. The "36" goes on forever
c = 11.36 cm
Answer:
angle c is 58 degrees and and angle a is 42 degrees
Step-by-step explanation:
Answer:
For Question 3, all you have to do is subtract 5 from both sides of the equation, then divide by -3, which will leave you with 5 as the answer.
-3x + 5 = -10
-3x = -15x
x = 5
The solution to the problem is as follows:
V = 1/3 * area of base * height
V = 1/3 * 3 * 4
V = 4 in^3
576/4 = 144 => max number of pyramids made out of the block of alabaster.
