Answer:
= −11.2
Step-by-step explanation:
64.8=6(m+22)
We move all terms to the left:
64.8-(6(m+22))=0
We calculate terms in parentheses: -(6(m+22)), so:
6(m+22)
We multiply parentheses
6m+132
Back to the equation:
-(6m+132)
We get rid of parentheses
-6m-132+64.8=0
We add all the numbers together, and all the variables
-6m-67.2=0
We move all terms containing m to the left, all other terms to the right
-6m=67.2
Answer:
Step-by-step explanation:
d = c/pi
so d = 62.8/pi
d = 62.8/pi or appr 19.99in
r = d/2
so r = 62.8/2pi or 31.4/pi appr 19.99/2

so

then

so
a = approximately 313.84
answer is rowan

Answer:
A. Height of the Flag pole
B. Longest.
Explanation:
Two similar triangles have corresponding sides with the same ratio.
A smaller triangle is showing the shadow of a person and the larger one is showing the shadow of a flag.
Now the person's shadow in the smaller triangle corresponding to the Height of the Flag pole.
The longest side of the large triangle corresponds with the Longest side of the smaller triangle.
