A large rectangular swimming pool is 1,000 feet long 100 feet wide and 10 feet deep how much water does the pool hold?
Ymorist [56]

ANSWER

The swimming pool can hold 1,000,000 cubic feet of water.

EXPLANATION

The capacity of water the pool holds is the volume of water in the swimming pool.

The swimming pool is rectangular, therefore its volume can be calculated using the formula,

V = l \times w \times h

where l=1000ft is the length, w=100ft is the width and h=10ft is the height of the pool.

We substitute all these values into the formula to get:

V = 1000 \times 100 \times 10 = 1000000 {ft}^{3}

The swimming pool can hold 1,000,000 cubic feet of water.

What percent of 1/4 is 2/3 and what percent of 1/6 is 2/3 ?
vlada-n [284]

Answer:

The percentages are 267% and 400% respectively.

Step-by-step explanation:

To find the answers of these, you need to divide the second number by the first. This will give you the percentage.

2/3 ÷ 1/4 = 8/3 = 2.67 = 267%

You can do the same for the second one.

2/3 ÷ 1/6 = 12/3 = 4 = 400%

reflection symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in it
OlgaM077 [116]

Answer:

True if reflection over a line.

Step-by-step explanation:

Given that there is a reflection symmetry. We have to discuss about the quality of the design.

By reflection , we mean it can be either on a line or on a point.

If symmetry is on a line, then we get a mirror image of the original one keeping the line of symmetry as mirror.  Hence in this case when rotated about axis of symmetry lying it its plane the original design would be maintained.

Examples are : Circles, ellipses, hyperbolas, etc.

Reflection about a point is obtained by keeping equal distance form the point.

For example, reflection of (1,1) over origin would be (-1,-1)

Here the rotation quality may not apply
