Betsy can clean a b of the house in an hour. How long will it take her to clean the whole house?

kipiarov [429]

Answer:

$\frac{b}{a}$ is the total time taken to clean the house.

Step-by-step explanation:

Given that:

Betsy cleans $\frac{a}{b}$ of the house.

Time taken = 1 hour

To find:

Time taken to clean the whole house = ?

Solution:

We can use unitary method here to solve this problem.

We are given that $\frac{a}{b}$ of the house is cleaned in 1 hour.

We have to find that a total of 1 house will be cleaned in how much time.

(1 house because Betsy's house can be considered as a single unit).

To find this we will divide 1 hour with $\frac{a}{b}$ .

Now, Let us solve this mathematically:

$\frac{a}{b}$ of the house is cleaned in = 1 hour

1 of the house will be cleaned in = 1 hour divided by $\frac{a}{b}$

$\dfrac{1}{\dfrac{a}{b}}\ hours\\\Rightarrow \dfrac{1 \times b}{a}\ hours\\\Rightarrow \dfrac{b}{a}\ hours$

So, the answer is:

$\frac{b}{a}$ is the total time taken to clean the house.

Find the perimeter! 5x2 - 9x 2x2 + 7x + 11 4x – 15

Marina CMI [18]

Answer:

perimeter of a rectangular swimming pool is 154 m. Its length is ... 2x + 3x + 3 + 4x + 8 = 74. => 9x + 11 = 74. => 9x = 74 – 11. => 9x = 63 ... Solve the following equations and check your results: 2x/3 + 1 = 7x/15 + 3.

Alik [6]

The initial height is .5 m. If the ball only reaches 52% of the previous max height, then after the third bounce you have:
.5 x (.52)^3=0.070304 meters as the height of the ball
