An Olympic sized swimming pool holds 6.6043×10^5 gallons of water. A standard garden hose can deliver 9 gallons of water per min
bixtya [17]

6.6043×10^5 = 660,430 gallons.

660,430 / 9 = 73381.11... minutes.

73381.11... / 60 = 1223.01851852  hours.

1223.01851852 / 24 = 50.9591049383  days.

It would take about 51 days for the garden hose to fill the pool.

Lee and Maya are collecting leaves for an art project lee collects 25/100 of the total number leaves needed. Maya collects 4/10
MrRissso [65]

Answer:  The answer is \dfrac{13}{20}.


Step-by-step explanation:  Given that Lee and Maya are collecting leaves for an art project. Let'x' be the total number of leaves needed in the project.

Then, the number of leaves collected by Lee is given by

L_\ell=\dfrac{25}{100}x,

and the fraction of the leaves collected by Maya is given by

M_\ell=\dfrac{4}{10}x.

Therefore, the total number of leaves collected by Lee and Maya altogether is

L=L_\ell+M_\ell=\dfrac{25}{100}x+\dfrac{4}{10}x=\dfrac{25+40}{100}x=\dfrac{65}{100}x=\dfrac{13}{20}x.

Thus, the total fraction of the leaves collected by Lee and Maya is

\dfrac{13}{20}.

Given that A varies directly as B and inversely as C and that; A=12 when B=3 and C=2. Find B when A=10 and C=1.5​
Kitty [74]
<h3>Answer:</h3>

1.9

Step-by-step explanation:

<h3>The above is direct and inverse variation.</h3>

A = kB/C -----------(1)

A=12

B = 3

C= 2

substitute A, B and C into equation (1).

12 = K × 3/2

12 = 3k/2

12×2 = 3k

3K = 24

dividing bothsides by 3

3K/3 = 24/3

K = 8

substitute K = 8 into equation (1)

A = 8B /C --------------(2)

Equation (2) is the equation connecting

A,B and C.

Finding B when A = 10 and C = 1.5

10 = 8B / 1.5

10× 1.5 = 8B

15 = 8B

Dividing bothsides by 8 :

B = 15/8

B = 1.875

B = 1. 9 ( approximately)
