Answer:
Step-by-step explanation:
8)Volume of cylinder = πr²h= π*3*3*10 =90π cubic inches
Volume of cone = 1/3πr²h = π*3*3*5/3= 15π cubic inches
Volume of rocket = 90π + 15π = 105π cubic inches
9) Matt made an error. radius = diameter/2 = 15/2= 7.5 cm.Instead using 7.5 in volume formula, he used diameter.
Answer:
8/3 or 2 2/3
Step-by-step explanation:
We do sums and differences of fractions by giving them a common denominator, then finding the sum or difference of the numerators. Here, you can reduce the first fraction to 10/3, so it will have the same denominator as the second fraction.
Now, you have ...

Answer:
20 marbles total...7 are green
Step-by-step explanation:
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Answer:
Step-by-step explanation:
Use PEMDAS
First we have to do the operation inside parenthesis
-734 ÷(-112*3) = -734 ÷ -336 {Now division}
= + 2.18
