Solution 1

5/8, 2/6, 8/11, 2/5

Convert them into decimals.

5/8Â â‡’ 0.625

2/6Â â‡’ 0.333

8/11Â â‡’ 0.727

2/5Â â‡’ 0.4

The lowest amount is 0.333, or 2/6.

Lilly ate 2/6 of a pizza.

**Lilly ate the least amount of pizza.**

Convert them into decimals.

5/8Â â‡’ 0.625

2/6Â â‡’ 0.333

Question

The sum of Andy and Brett's ages is 44. Andy's age is 8 more than twice Bret's age. Find the solution.

Solution 1

Andy is 32, and Brett is 12. You gotta set up an equation.

a+b=44

a=2b+8

2b+8+b=44

b=12

a=32

a+b=44

a=2b+8

2b+8+b=44

b=12

a=32

Question

Tony is making small bags of bird seed from a larger bag of bird seed that wieghs 11.6 pounds if he puts the same amount in each of 6 bags how much will each bag wiegh?

Solution 1

For this case we have the following division:

Â Weight each bag = Total weight / number of bags

Â Substituting values we have:

Â Weight each bag = (11.6) / (6)

Â Weight each bag = 1.933333333 pounds

Â**Answer:**

Â**each bag will wiegh about:**

Â**1.933333333 pounds**

Â Weight each bag = Total weight / number of bags

Â Substituting values we have:

Â Weight each bag = (11.6) / (6)

Â Weight each bag = 1.933333333 pounds

Question

Heather and Joel bought a house for $157,200 and know that the house appreciates every year. They keep track of their house value for 5 years and model their data with the exponential equation

Solution 1

Given that they want to estimate the cost of the house after 8 years, the best equation will be obtained as follows:

FV=P(1+r)^n

where:

n=time

p=principle

r=rate

First we need to estimate the rate. The value of the house after 5 years is $ 190,000

thus plugging the values in the equation and solving for r we get:

190000=157200(1+r)^5

1.20865=(1+r)^5

getting the fifth root of both sides we obtain:

1.0386=1+r

thus

r=0.0386~3.86%

thus the value of the house after 8 years will be:

FV=157200(1.0386)^8

FV=$212,879.6936

FV=P(1+r)^n

where:

n=time

p=principle

r=rate

First we need to estimate the rate. The value of the house after 5 years is $ 190,000

thus plugging the values in the equation and solving for r we get:

190000=157200(1+r)^5

1.20865=(1+r)^5

getting the fifth root of both sides we obtain:

1.0386=1+r

thus

r=0.0386~3.86%

thus the value of the house after 8 years will be:

FV=157200(1.0386)^8

FV=$212,879.6936

Question

What is the opposite or addictive inverse of 43

Solution 1

The opposite addictive inverse of 43 is -43.

The opposite of a number is simply found by dividing by 1. If it were a negative number, it would become positive, and vice versa.
