Answer:
Yes, Sienna is correct because 6 times 2 is 12 and 3 times 4 is 12.
We need to write system of equations to solve this problem.
we have 3 unknown variables.
a,b,c which are shorter leg, longer leg and hypotenuse.
b = a+6
c+6 = 2*a
c^2 = a^2 + b^2
(2a - 6)^2 = a^2 + (a+6)^2
4a^2 - 24a + 36 = a^2 + a^2 + 12a + 36
2a^2 = 36a
a^2 = 18a
a = 18
b = 24
c = 30
Answer:
24% of 33.50 = 80.40
67% of 87.99 = 58.96 (rounded up from 58.9533)
6% of 8.75 = 0.53 (rounded up from 0.525)
Step-by-step explanation:
to find the persentage of a number, you can first devide the whole number by 100, then multiply by the persentage ur figuring out, heres an example
for 24% of 33.50. we first devide 33.50 by 100
<em>33.50 / 100 = 3.35</em>
then multiply by 24
<em>3.35 * 24 = 80.40</em>
note if there are three numbers before the decimal point, and ur working with cash, always round up t the nearest hundredth
Answer:
Step-by-step explanation:
- y² - 10y + 30 =
- y² - 10y + 25 + 5 =
- (y - 5)² + 5
<u>Since (y - 5)² ≥ 0, the expression above is positve:</u>
