The area of a triangle is 14 square units it has a side length of a and b what is the value of b if a is 1/5

Answers

Answer 1

Answer:

140 ft

Step-by-step explanation:

Given data

Area= 14 square feet

Height a = 1/5 ft

Base b=????

We know that the area of a triangle is given as

Area= (1/2)B*H

substitute

14= 1/2* B* 1/5

14= B/10

cross multiply

B= 140

 

Hence the base is 140 ft

Car survey in a survey of 1200 people who owned a certain type of car,600 said they would buy that type of car again.What percent of people surveyed were satisfied with the car?

Answers

Answer:

50 percent

Step-by-step explanation:

Total number of people in this car survey = 1200

Total number of people who they would still buy same car type = 600 (these are the satisfied people)

The percentage = 600/1200 x 100

= 0.5 x 100

= 50 percent

So the percentage of satisfied people who would buy this type of car again is 50%

Avante walked 1 and 1/2 miles in 22.5 minutes. Avante walked at a constant rate. How long did it take him to walk 1 mile?

Answers

1 1/2 miles is the same as walking 1/2 a mile 3 times, so we can divide 22.5 minutes by 3 to find how long it takes to walk half a mile
22.5/3=7.5
We can then multiply 7.5 by 2 to get how long it takes to walk 1 mile
7.5 x 2 = 15 minutes
It takes Avante 15 minutes to walk 1 mile

What is the simplified form of √45

Answers

Answer:

3√5

Step-by-step explanation:

The largest perfect square of the factors of 45 is 9. We can therefore convert √45 like this:

√9 × 5

Next, we separate the numbers inside the √ as such:

√9 × √5

√9 is a perfect square that equals 3. We can therefore put 3 outside the radical and get the final answer to square root of 45 in simplest radical form as follows:

Do not factor by grouping. Solve 2(x-2)^1/3=x+2

Answers

Step-by-step explanation:

2(x-2)⅓=x+2

so we first cube each side,such that...

(2(x-2))⅓•³=(x+2)³

we get...

2(x-2)=(x+2)³

expanding...

2x-4=x³+6x²+12x+8

grouping....

x³+6x²+12x+8-2x+4=0

solving...

x³+6x²+10x+12=0

now you can use you calculator to solve for the possible values of x
