First take the square root of 25, then take the square root of 49.
It is as easy as separating the square root to apply to both terms separately instead of combined.
sqrt(25)/sqrt(49)
5/7
Answer:
y equals times 2 i think
Step-by-step explanation:
Answer:
Perimeter = 17a
Area = 30 square meters
Step-by-step explanation:
Perimeter = 2b + 8 = 10b + 5 + a = 15ab + 2a - b = 17a
Area = 2 + 8 = 10 + 2 = 12 × 5 = 60 simplify
I honestly don't know if this is correct, I hope it is
<u>EXPLANATION </u>
First you will need <u>TWO</u> numbers. One being the percentage and the other being the number your trying to find the percent out of.
<u>EXAMPLE</u>
Imagine you have 130 crayons. Out of the 130 crayons you found that 15% of them were broken.
First you want too take the 15% and put it over 100, because a percentage always goes over 100. Now that you have the 15/100 you now wanna take the 130 crayons and put the variable <u>X</u> over it. Now that you have the fractions 15/100 and X/130 you want to cross multiply them to get <u>100x </u>and <u>1950</u>. For the final step your going to want to take 1950 and divide it by 100 to get your answer, <u>19.5</u>.
I hope this helped you find out the method for solving a percentage problem while using proportions.
Answer:
25.7 m
Step-by-step explanation:
Hello!
We have two sides each measuring 5m, so the length of the straight edges is 2(5m) or 10m
We also have two identical semi-circle circumferences, so if we find the circumference of the whole circle, we can find the total length of the curved edges.
- C = 2πr
- C = 2(3.14)(2.5)
- C = 5(3.14)
- C = 15.7
Now, we can add up the two lengths:
- Perimeter = straight sides + curved sides
- Perimeter = 10m + 15.7m
- Perimeter = 25.7m
