Let's called this number x and sum it with 35
x+35
We know this sum is equal to 100, let's equal it.
x+35=100
proportions are just equivalent fractions
-5/-10 would be your answer =)
8
You multiply the numbers
Answer:
I believe it would be 9 hours for company 1, and 10 for company 2
Step-by-step explanation:
30 x 9 = 270 (+ the first 20) =290
25 x 10 = 250 (+ the first 40) =290
Answer:
![42.5\:\mathrm{m^2}](https://tex.z-dn.net/?f=42.5%5C%3A%5Cmathrm%7Bm%5E2%7D)
Step-by-step explanation:
The area of a sector with measure
in degrees is given by
, where
is the radius of the sector.
What we're given:
Solving, we get:
![A_{sector}=5^2\pi\cdot \frac{195}{360}=13.5416666667\pi=42.5424005174\approx \boxed{42.5\:\mathrm{m^2}}](https://tex.z-dn.net/?f=A_%7Bsector%7D%3D5%5E2%5Cpi%5Ccdot%20%5Cfrac%7B195%7D%7B360%7D%3D13.5416666667%5Cpi%3D42.5424005174%5Capprox%20%5Cboxed%7B42.5%5C%3A%5Cmathrm%7Bm%5E2%7D%7D)
*Notes:
- units should be in square meters (area)
- the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
