The ratio of martas hourly pay to khalids hourly pay is 6:5

Talja [164]

The hourly pay before the increase for marta and khalid is 21 and 17.5.

Given:

the ratio of martas hourly pay to khalids hourly pay is 6:5 both marta and Khalid get an increase of 1.50 in their hourly pay The ratio of Martas hourly pay to Khalid hourly pay after this increase is 13:11

Let x and y be the hourly pay before increase

x/y = 6/5

x = 6/5*y

x + 1.50 / y + 1.50 = 13/11

11(x+1.50) = 13(y+1.50)

11x + 16.5 = 13y + 19.5

11(6/5*y) = 13y + 19.5 - 16.5

66y/5 = 13y + 3.5

66y - 13*5y / 5 = 3.5

66y - 65y = 17.5

y = 17.5

x = 6/5*17.5

= 105/5

x = 21

At the first track meet, Lonnie threw the shot put 51 1/3 feet. At the second track meet he threw the shot put 54 1/2 feet. Writ

mars1129 [50]

Answer:

Step-by-step explanation:

At the first track meet, distance of the shot put throw $D_{1}$ = $54\frac{1}{3}$

At the second track meet distance of the throw $D_{2}=54\frac{1}{2}$ feet

Expression that represents the improvement in the throw will be

D = $D_{2}-D_{1}$

D = $54\frac{1}{2}-51\frac{1}{3}$

D = $\frac{109}{2}-\frac{154}{3}$

D = $\frac{327-308}{6}$

D = $\frac{19}{6}$

D = $3\frac{1}{6}$ feet

It takes four minutes to fill a bathtub if the hot and cold water taps are both on and the stopper is in. It takes six minutes t

bekas [8.4K]

Answer:

12 minutes

Step-by-step explanation:

Since it takes 4 minutes to fill the bathtub with both taps on and stopper is in then for each minute the 2 taps can fill up to a quarter (1/4) of the tub:

Similarly, it takes 6 minutes to drain the tub with both taps off and the stopper is out. This means for each minute the stopper can drain one sixth (1/6) of the tub.

Therefore, when both taps are on and the stopper is out, then for each minutes, the amount of water remaining in the tub is the water flowing in minus the water draining out

$\frac{1}{4} - \frac{1}{6} = \frac{3}{12} - \frac{2}{12} = \frac{1}{12}tub$

So for each minute, one twelveth of the tub is filled, for the tub to be completely filled in, it would take 12 minutes
