If four friends assist, it will take 13.12 hours to construct the tree home.

What is algebraic Expression?

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Given this, Peter figures he can build the entire tree house by himself in 20 hours. He figures that each additional friend who helps him would improve the time by 10%.

An algebraicexpression that determines the given condition is:

n – n(0.10)

=> n(1- 0.1)

=> n* 0.9

Since the above equation is for A friend and it's given there are four friends helping him.

Thus,

The final time is taken in building the tree house if 4 friends are helping:

=> n * 0.9^4

Where n is 20

=> 20 * 0.9^4

=> 13.122

Therefore, it will take 13.12 hours to build the tree house if 4 friends are helping.

How to write 80a^3/4 in radical form

Answers

easy peasy
ok so remember
x^{ (m)/(n) } = \sqrt[n]{x^(m)}
so
80a^{ (3)/(4) } = \sqrt[4]{80a^(3)}
80=2^4*5 
 80a^{ (3)/(4) } = 2\sqrt[4]{5a^(3)}

Answers

Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6)    ------>    6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.

What is the ratio of ounces to pounds in the weight of an object

Answers

Answer:

1 : 0.0625

Step-by-step explanation:

We are asked to find the ratio of ounces to pounds in the weight of an object.

We know that 1 pound equals 16.

Ratio of pound to ounce= 1 : 16

To find the ratio of ounces to pounds, we will divide 1 by 16.

(1)/(16)=0.0625

Ratio of ounce to pound= 1 : 0.0625

Therefore, our required ratio is 1 : 0.0625.
1 Pound = 16 Ounces
1 Ounce = 0.0625 Pounds
