Yesterday it took 5 cleaners 4 and 1/2 hours to clean all the rooms in a hotel. There are only 3 cleaners to clean all the rooms

beks73 [17]

If 5 cleaners took 4 hours and 30 min. to clean the whole rooms in a hotel and there's only 3 cleaners, it would take them 6 hours and 30 min. why? because 5 cleaners = 4 hours and 30 min. 4 cleaners = 5 hours ad 30 min. 3 cleaners = 6 hours and 30 min. Anyway so, if they were paid 8.20 for each hour you would multuply that so 8.20x6.5 = ?? and then you divide the answer to 3 and thats your answer

A square pyramid and a cube have the same surface area. The length of each side of the base of the square pyramid is 10 feet. Th

Brrunno [24]

Answer:

The answer to your question is 23.2 ft

Step-by-step explanation:

Data

length square pyramid = 10 ft

width of a cube = 6 ft

height of the pyramid = ?

The surface area is equal in both figures.

Formula

Surface area of a cube = 6a²

Surface area of a square pyramid = ab + al = l x l + (l x h) /2

Process

1.- Calculate the surface area of the cube

Ac = 6(6)² = 6(36)

= 216 ft²

2.- Substitute data in the square pyramid formula

Ap = (10 x 10) + (10h)/2

3.- Equal both areas

216 = 100 + 5h

- Solve for h

216 - 100 = 5h

116 = 5h

h = 116 / 5

- Result

h = 23.2 ft

Jenny multiplies the square root of her favorite positive integer by $\sqrt{2}$. Her product is an integer. a) Name three number

Dmitry [639]

Answer:

Part a) $2,50,18$

Part b) When Jenny divides the square root of her favorite positive integer by $\sqrt{2}$ , she gets an integer

Step-by-step explanation:

Let

x-------> the favorite positive integer

Part a)

1) For $x=2$

$\sqrt{2}*\sqrt{2}=\sqrt{4}=2$ -----> the product is an integer

so

The number $x=2$ could be Jenny favorite positive integer

2) For $x=50$

$\sqrt{50}*\sqrt{2}=\sqrt{100}=10$ -----> the product is an integer

so

The number $x=50$ could be Jenny favorite positive integer

3) For $x=18$

$\sqrt{18}*\sqrt{2}=\sqrt{36}=6$ -----> the product is an integer

so

The number $x=18$ could be Jenny favorite positive integer

Part B)

1) For $x=2$

$\sqrt{2}/\sqrt{2}=\sqrt{1}=1$ -----> the result is an integer

2) For $x=50$

$\sqrt{50}/\sqrt{2}=\sqrt{25}=5$ -----> the result is an integer

3) For $x=18$

$\sqrt{18}/\sqrt{2}=\sqrt{9}=3$ -----> the result is an integer

Therefore

When Jenny divides the square root of her favorite positive integer by $\sqrt{2}$ , she gets an integer
