Can you help me with this other question please?A frozen yogurt shop offers scoops in cake cones, waffle cones, or cups. You can get vanilla, chocolate, strawberry, pistachio, or coffee flavored frozen yogurt. If you order a single scoop, how many outcomes are in the sample space? I didn't really understand it.

Answers

There is 4 outcomes per cone/cups so therefore the answer 4*3 which equals 12.
I think if you got 1 scoop, then there would be 7 possible outcomes. I hope this helps!

The volume of a cylinder, found using 3.14 to approximate pi, is 50,240 cm3. The radius of the cylinder is 40 cm.What is the height of the cylinder?



Express your answer as a whole number.

Answers

V=hpir^2
pi=3.14 for this quesiton
v=50240
r=40
subsitute and solve
50240=h(3.14)(40^2)
50240=h(3.14)(1600)
50240=h(5024)
divide both sides by 5024
10=h

answer is height=10cm



108 identical books have a mass of 30 kg. Find(i) the mass of 150 such books,
(ii) the number of such books that have a mass
of 20 kg.

Answers

Answer:

The mass of 150 books = 41.7kg

The number of books that have mass 20kg = 72 books

Step-by-step explanation:

(I) Number of identical books = 108

Mass of  books = 30 kg

Mass of 150 books = ?

Let the mass of 150 books = x kg

To find the mass of 150 books we will use ratio and proportion:

108 books: 30kg = 150 books: x kg

You can also write it like this because ratio can be written in division:

108/30 = 150/x

By cross multiplication:

108x = 150*30

108 x= 4500

Divide both sides by 108

108 x/108 = 4500/108

x= 41.7

Thus the mass of 150 books = 41.7kg

( ii ) The number of books that have a mass of 20 kg = ?

Let assume that the number of books of mass 20 kg = y books

We will again use ratio and proportion method.

108 books: 30kg = y: 20kg

We can write it as:

108/30 = y/20

By cross multiplication:

108 *20 = 30y

2160= 30y

Divide both the terms by 30

2160/30 = 30y/30

72 = y

Therefore the number of books that have mass 20kg = 72 books ....

Emily pays 15 % on her total income. if she earns 11500 dollars a year how mich money does she have left​

Answers

Answer: 9775 dollars

====================================

Explanation:

There are two ways to find the answer

Method 1: Take 15% of 11500 to get 0.15*11500 = 1725. This is the amount Emily pays, so she has 11500-1725 = 9775 dollars left over

Method 2: She pays 15% of her income, so she has 85% left over. This is because 100% - 15% = 85%. Now apply 85% to her income to get 0.85*11500 = 9775

Answer:

$97750
