An oil tanker can be emptied by the main pump in 5 hours. An auxiliary pump can empty the tanker in 7 hours. If the main pump is
r-ruslan [8.4K]

Answer:

so the answer will be 1

Step-by-step explanation:

An oil tanker can be emptied by the main pump in 5 hours.

An auxilary pump can empty the tanker in 14 hours.

If the main pump is started at 7pm, when should the auxilary pump be started

so that the tanker is emptied by 11pm?

:

Let t = no. of hrs to run the Aux pump

:

The main pump will run 4 hr (7 - 11 pm)

:

Let the completed job = 1; (an empty Tanker)

:

The shared work equation

4%2F5 + t%2F14 = 1

Multiply equation by 70 to get rid of the equation, results:

14(4) + 5t = 70

56 + 5t = 70

5t = 70 - 56

5t = 14

t = 14%2F5

t = 2.8 hrs to run the aux pump

:

2.8 hr = 2 + .8(60) = 2 hrs 48 min

:

Subtract 2:48 from 11:00 = 8:12 PM start the aux pump

;

;

Check solution

4/5 + 2.8/14 =

.8 + .2 = 1

30<br> 20<br> Y<br> Find x<br><br> Can someone please help me
irakobra [83]

Answer:

B

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = \frac{\sqrt{3} }{2} , then

cos30° = \frac{adjacent}{hypotenuse} = \frac{x}{20} = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 20\sqrt{3} ( divide both sides by 2 )

x = 10\sqrt{3} → B

Please factor these three questions- (30 points)
julia-pushkina [17]

Answer:

(a - 6)²

(3c + 1)²

30e(e - 1)²

Step-by-step explanation:

a^2-12a+36

a² - 6a - 6a + 36

a(a - 6) - 6(a - 6)

(a - 6)(a - 6)

(a - 6)²

9c^2 + 6c + 1

9c² + 3c + 3c + 1

3c(3c + 1) + 1(3c + 1)

(3c + 1)(3c + 1)

(3c + 1)²

30e^3 - 60e^2 + 30e

30e(e² - 2e + 1)

30e(e² - e - e + 1)

30e[e(e - 1) - (e - 1)]

30e(e - 1)(e - 1)

30e(e - 1)²
