sweet-ann [11.9K]

Answer:

5. f(x) = 10,000 (1.5)^x

Step-by-step explanation:

We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

Let's test it.

Initial:

10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

After 2 years

15,000 + (.5*15000)

15,000 + 7500 = 22,500

Let's try our equation.

f(x) = 10,000 (1.5)^x

x = 2

10,000(1.5)^2

10,000(2.25) = 22,500

The same!

aalyn [17]

Answer:

5:24

Step-by-step explanation:

We're provided with the number of rebounds as 90 while the points are 432. Expressing them into ratio of rebounds to steals we have

90:432

Simplification:

Dividing both sides by 2 we obtain

45:216

Dividing both sides of the above ratio by 3 we obtain

15:72

Dividing both sides of the above ratio further by 3 we obtain

5:24

Therefore, rhe simplified ratio of rebounds ro steals is 5:24

Bogdan [553]

Answer:

Each person would get 4 cup cakes if all 8 friends attend the party.

Each person would get 12 cup cakes when 6 friends not attended the party.

Step-by-step explanation:

Given:

Total Number of cup cakes = 36

Number of friends coming to party = 8

Total number of people cakes need to distributed including George = 9

We need to find the number of cup cakes each person would get;

Solution:

Now we can say that;

number of cup cakes each person would get is equal to Total Number of cup cakes divided by Total number of people cakes need to distributed including George.

framing in equation form we get;

number of cup cakes each person would get = $\frac{36}{9}=4$

Hence Each person would get 4 cup cakes if all 8 friends attend the party.

Now Given:

Number of friends not attended the party = 6

So we can say that;

Total number of people cakes need to distributed including George = 9 - 6 = 3

So we can say that;

number of cup cakes each person would get = $\frac{36}{3} =12$

Hence Each person would get 12 cup cakes when 6 friends not attended the party.
