Answer:
Step-by-step explanation:
A tennis ball is a sphere
Volume of a sphere ===> v= \frac{4}{3} \pi r^3
Plug in the given info
v= \frac{4}{3} (3.14) (6.7)^3
Do the math to get a final answer of:
v= \frac{4}{3} (3.14) (6.7)^3=1259.19cm^3

Jenna writes 5 fewer facts than Cleo. Let "c" = number of facts Cleo writes.
So an expression we can use to figure out how many facts Jenna writes is:
c - 5
So the table could look something like this:
10 ║ c-5 ║ 5
11 ║ c-5 ║ 6
12 ║ c-5 ║ 7
So if Cleo writes 31 facts, we can still use: c - 5
Plug in c = 31 to get:
31 - 5 = 26 facts for Jenna
Answer:
x = 27
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.
To solve for x, cross multiply:
(x+8)(14) = (10)(2x-5)
14x + 112 = 20x -50
112 = 6x - 50
162 = 6x
27 = x
Question seem incorrect because 60%,50% and 20% sum up to more than a 100% therefore we've made a little correction
Answer:
0.8
Step-by-step explanation:
Probability = number of favorable outcomes/number of outcomes
Given that 30% are entertained by reading books
50% are entertained by watching TV
20% are entertained by reading books and watching TV
The probability that a person will be entertained by books or TV =
30/100+50/100= 3/10+5/10
=8/10
=0.8
Answer:
i think 5 so i say pick 5 because 19no 12no10 no so it 5
