Vadim26 [7]3 years ago
5 0

Answer:

16) 9ft, C

17) 1440 cm^3, D

18) 314 m^2, B

Step-by-step explanation:

16) 18 / 6 = 27 / x

18x = 162

x = 9 (C)

17) 24 / 1,920 = 18 / x

24x = 34,560

x = 1440 (D)

18) Surface Area of a sphere = 4 * pi * radius^2 (4r^2)

SA = 4pi(5)^2

SA = 4pi25

SA = 100pi

SA = 100(~3.14)

SA = 314 (B)

Jen picked 3/4 of a gallon of strawberries in half an hour. If she keeps picking strawberries at the same rate, how many gallons
scoray [572]
Well following the directions you have provided me I would say that Jen will have 3 Gallons of strawberries. Work: So the fraction 3/4 can be converted into decimals which is .75 and since she got that many in half and hour ( 30 minutes) we can do two set of .75 for each hour, after we do the math we end up with 4 sets in total of .75 since she had 2 hours to work. Equation .75*4=3 

I hope this helped you out!

There are twelve signs of the zodiac. How many people must be present for there to be at least a 50% chance that two or more of
Nutka1998 [239]

Answer:

5

Step-by-step explanation:

Given that each zodiac sign occupies 1/12 of a year.

Then the minimum number of persons for Y[all different signs] < 0.5,

The probability of at least two having the same sign is 1 minus the probability of all having different signs.

This can be represented as A [at least 2 person share the same sign] = 1 - Y[all different signs] must be > 0.5

Therefore we have 1 - 12/12 *11/12 * 10/12 *9/12 *8/12 = 0.38

This implies that the lowest number will be found to be 5

Hence, the correct answer is 5.
