Answer:
20 miles
Step-by-step explanation:
Let d be the distance. Then:
11/66=d/120
66d=1320
d=20 .......................
Answer:
1) C. 2
2) A. 2
Step-by-step explanation:
1. We need to descompose 256 into its prime factors:

We must rewrite the expression
:
![=\sqrt[8]{2^8}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B8%5D%7B2%5E8%7D)
We need to remember that:
![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
Then:

2. Let's descompose 16 into its prime factors:

We must rewrite the expression
:
![=\sqrt[4]{2^4}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B4%5D%7B2%5E4%7D)
Then we get:

Answer:
55
Step-by-step explanation:
35+90=125
180-125=55
The interior angles of a triangle should always add up to 180 degrees
<span>12x - 3y ≤ -21
Subtract 12x from both sides
-3y </span>≤ -12x - 21
Divide both sides by -3.
y

4x + 7
