A large rectangular swimming pool is 1,000 feet long, 100 feet wide, and 10 feet deep. The pool is filled to the top with water.
MArishka [77]

Answer:

It's a simple question. This swimming pool is basically a rectangular cuboid. Length x Width x Height = how much water it will hold.

Water = 1000000 feet^(3)

Step-by-step explanation:

1000 x 100 x 10 = 1000000 feet^(3)

or you could just converted to meters cube which should be 28316.85 (ish).

5. Simplify the expression and find its value when p= 4 and q = -5:
Ierofanga [76]
  • <u>Answer</u>: -180

Step-by-step explanation:

\bf   \blue{ \boxed{  \bf p = 4 \:  \: and \:  \: q =  - 5 \Rightarrow pq = 4 \times ( - 5) =  - 20}}

3(p2q + pq2 - pq) - 6pq + 3pq2 =

3[-20 × 2 + (-20) × 2 - (-20)] - 6 × (-20) + 3 × 2 × (-20) =

3[-40 + (-40) + 20] - 6 × (-20) + 3 × 2 × (-20) =

3(-40 - 40 + 20) - 6 × (-20) + 3 × 2 × (-20) =

3(-80 + 20) - 6 × (-20) + 3 × 2 × (-20) =

3 × (-60) - 6 × (-20) + 3 × 2 × (-20) =

-180 + 120 + 6 × (-20) =

-180 + 120 + (-120) =

-180 + 120 - 120 =

-60 - 120 = -180

Let a equal measure of a angle a. The equation 360゚= a + 90゚+ 135゚+ 75゚ represents the sum of the angles in the quadrilateral. F
lina2011 [118]

Answer:

A = 60°

Step-by-step explanation:

First to find the missing angle you add the three known angles,

90 + 135 + 75 = 300

Then, you subtract, 360 - 300 = 60

<h3>So, 360° = 60° + 90° + 135° + 75°</h3><h3 />

Ginnie plans to paint a wall. She measures its height and width. She finds that she needs enough paint to cover 8 square meters.
SOVA2 [1]

Answer:

The 8 square meters represent the product of the height by the width of the wall and therefore, its area.

Step-by-step explanation:

Ginnie is going to paint a wall and measures the height and the width, the walls are usually in the form of a rectangle or square. To find the area of both we need to multiply the height by the width (in the case of the square both are the same) and this will give us the total amount of paint that we need to paint the wall.

In this example, Ginnie finds that she needs enough paint to cover 8 square meters, therefore, these 8 square meters represent the product of the height by the width (that we don't know but it doesn't matter) of the wall and therefore, its area.
