Answer:
Question 2 is 6
Step-by-step explanation:
I don’t understand what your asking on if you can simplify what is the GCF
Step-by-step explanation:
Volume of Barrel : [pi x h(r² + 2R²)] / 3
Barrel A : 2pi(r² + 2R²)]/ 3
Barrel B : 5pi(r² + 2R²)]/ 3
Barrel A + Barrel B = 532
5pi(r² + 2R²)/3 + 2pi(r² + 2R²)/3 = 532
5pi(r² + 2R²) + 2pi(r² + 2R²) = 1596
7pi(r² + 2R²) = 1596
pi(r² + 2R²) = 228
Barrel A = 2 x 228/3 = 76 ft³ SMALLER
Barrel B = 5 x 228/3 = 380 ft³
hope it's helpful, I'm not sure if (r) and (R) are the same if the two barrels has a similar shape. but if they're the same, then the answer is correct
Answer:
Step-by-step explanation:
Look at the picture.
The formula of an area of a triangle:
<em>b</em><em> - base</em>
<em>h</em><em> - height</em>
<em />
We need a length of a height.
Use the Pythagorean theorem:
We have:
Substitute:
<em>subtract 25 from both sides</em>
Calculate the area:
Answer:
6x3+5=23
Step-by-step explanation:
Answer:
25 questions
Step-by-step explanation:
20 questions = 80% If she got 80%, that means she got 20 questions correct.
5 questions = 20% Here, we simply just divide by 4 to give us 20%.
25 questions = 100% The total of the test would of course equal 100%, so we just multiply by 5 to give the total questions.
I hope this helps you!! ^-^
