Find the two numbers whose sum is54 and whose difference is 4

Answers

Answer: I can not see the picture

Step-by-step explanation:

can you show it?

Sum of 54: X + Y = 54
Difference is 4: X - Y = 4

Solve for one variable first.

X = 4 + y (rewritten from second equation)

Now plug into the first equation for x

4 + y + y = 54
4 + 2y = 54 (subtract 4)
2y = 50 (divide by 2)
Y = 25

Now use Y to solve for X

X - 25 = 4 (add 25 on each side)
X = 29

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. The drain pipe can be used to empty the pool in 34 hours. If the pool is [tex]\frac{2}{3}[/tex] filled and then the inlet pipe and drain pipe are opened, how many more hours would it take to fill the pool? Round your answer to two decimal places, if needed.

Answers

Answer:

374 hours

Step-by-step explanation:

Filling rate is 1/33Draining rate is 1/34

The difference is the filling rate with both lines open:

1/33 - 1/34 = 1/1122

The pool is 2/3 full and needs filling the remainder, 1/3.

Time required to fill:

1/3 : 1/1122 = 1122/3 = 374 hours

3. What is 11% of $3,000? • A) $250 e B) $300 • C) $380 • D) $350​

Answers

Answer:

$330.00

Step-by-step explanation:

Hey there!

The word ‘of’ in math means multiply

And

11% of 3,000

= 11/100 * 3,000

= 11/100 * 3,000/1

= 11(3,000)/100(1)

= 33,000/100

= 33,000 ÷ 100/100 ÷ 100

= 330/1

= 330

Therefore, the answer is most likely: 330

(NONE of the ABOVE)
