An Olympic pool is rectangular with a length of 50 meters. Ms Burri wants to fit an Olympic pool in her backyard but doesn't have enough room so she plans to build a similar pool with a length of only 30 meters.

a. She wants to replace the pool deck around her new smaller pool. What is the ratio of the perimeter of the Olympic pool to the new smaller pool?

b. The area of the olympic pool is 1,2500 meters squared. If she were to buy a pool cover to fit her brand new smaller pool, what would the area be?

Answers

Perimeter of older

2(50+W)100+2W

Perimeter of newer

2(30+W)60+2W

As w is constant cancel it

Ratio

100/605/3

Ratio of area is also same

So

5/3=12500/x5x=37500x=37500/5x=7500m²

Answer:

See below ~

Step-by-step explanation:

Finding perimeter of Olympic pool and regular pool :

P (olympic) = 2(l + w) = 2(50 + w) = 2w + 100P (regular) = 2(l + w) = 2(30 + w) = 2w + 60

Taking the ratio :

2w + 100 : 2w + 60100 : 605 : 3

Using ratios to find area of regular :

5 : 3 = 12,500 : aa = 12500/5 x 3 = 2500 x 3a = 7,500 m²

11. a bag contains 8 red marbles, 9 yellow marbles, and
7 green marbles. how many additional red marbles
must be added to the 24 marbles already in the bag so
that the probability of randomly drawing a red marble
is
15.
a 11
b. 16
c. 20
d. 24
e. 32

Answers

To get a probability of 3/5, 16 red marbles must be added.

How many additional red marbles must be added?

There are 8 red, 9 yellow, and 7 green marbles, for a total of:

8 + 9 + 7 = 24.

The probability of getting a particular color of marble is given by the quotient between the number of marbles of that color and the total number of marbles.

Here, we want to get a probability of drawing a red marble equal to 3/5.

So, if we add x red marbles, the probability of getting a red marble will be:

P = (8 + x)/(24 + x)

And that must be equal ot 1/5, then we write:

(3/5) = (8 + x)/(24 + x)

If we multiply both sides bt (24 + x), we will get:

3*(24 + x)/5 = 8 + x

Now we can solve that for x.

3*24/5 - 8 = x - x(3/5) = (2/5)*x

x = (3*24/5)*(5/2) - (5/2)*8 = 16

So 16 red marbles must be added, the correct option is b.

equation that shows 3 less than the product of 4 and m

Answers

The equation that shows 3 less than the product of 4 and m is 3 < 4m

Formation of equation

Formation of equation is a means of transforming statements into equations

The product of 4 and m is 4m

If 3 is less than the product of 4 and m, this is expressed as:

3 < 4m

Divide both sides by 4

3/4 < m

m > 3/4

Hence the equation that shows 3 less than the product of 4 and m is 3 < 4m

What is the area of a rectangle?

The area of a rectangle is the multiplication of the length and the width of the rectangle.

The area of the rectangle is expressed as:

Area (A) = length (L) × width (w)

A = l × w

Given that:

width = xLength = 2x - 7Area = 72 in ²

72 = (2x - 7) × (x)

72 = 2x² - 7x

2x² - 7x - 72 = 0

Using the quadratic calculator

x = 8 or x = -9/2

However, since our length/width distance can't be negative, then:

x = 8

width = 8 inchesLength = 2(8) - 7 = 9 inches

Answer:

5 × 5 ÷ 8 = 3 ¹/₈

Step-by-step explanation:

Using the order of operations we need to work from left to right.

Therefore we should carry out the multiplication first.

5 × 5 means "5 lots of 5"

⇒ 5 × 5 = 5 + 5 + 5 + 5 + 5 = 25

Now we need to divide 25 by 8.

8 + 8 + 8 = 24

Therefore, 8 goes into 25 three times with a remainder of 1.

So,  5 × 5 ÷ 8 = 3 ¹/₈
