Answer:

3 minutes

Step-by-step explanation:

Let's say that the bathtub is 15L

It would take 7.5 mins to fill 15L

15L/7.5 = 2L per minute

The other tap would take 5 minutes to fill 15L

15L/5 = 3L per minute

3L per minute + 2L per minute = 5L per minute

15L/5L per min = 3 minutes

Sorry for the delay. Accidentally pressed the answer button without the answer. Hope I helped.

When Malia measures the longer side of a dollar bill from her rule it will be approximately 6.14 inches in length. The ruler normally has inches and cm sides. Very few rulers have mm scales. The most probable scale that malia would have measure is in inches.

The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square fee
valentina_108 [34]
<h3>Therefore the area of remaining board  =13.76 square feet</h3>

Step-by-step explanation:

Given , The length of side of the square is 8 feet.

Since a circle is inscribed in the square. Then the diameter of the circle is equal to the length of side of the square .

Therefore the diameter of the circle is = 8 feet.

Radius of the circle is(r) = \frac{8}{2} feet = 4 feet

The area of the circle is= 3.14 r²

                                       = 3.14 × 4² square feet

                                      = 50.24 square feet

The area of the square  is = side × side

                                          = 8×6 square feet

                                          =64 square feet

Therefore the area of remaining board = (64- 50.24)square feet

                                                                 =13.76 square feet
