Answer:

Sue played 30 games

Step-by-step explanation:

Probability is typically given as a fraction or percentage where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. Since Sue's won 12 games and estimated the probability to be 0.4 or 4/10, you can set up a proportion, or equivalent ratios, to solve for the number of games she played:

$\frac{gameswon}{totalgames}=\frac{12}{x}=\frac{4}{10}$

Cross multiply: 4x = 120

Divide by 4: 4x/4 = 120/4

Solve for 'x': x = 30 games

A cylindrical swimming pool has a diameter of 20 feet and a height of 3.5 feet. How many gallons of water can the pool contain?

kvasek [131]

Answer:

The swimming pool will contain approx $8243\ gal$ of water.

Step-by-step explanation:

Given the swimming pool is in a cylindrical shape.

And the dimensions are $20\ feet$ diameter with a height of $3.5\ feet.$

Also, $1\ ft^3 =7.5\ gal$

First, we will find the volume of the swimming pool.

The swimming pool is in cylindrical shape.

So, the volume would be $\pi r^2h$

The height $(h)$ is given as $3.5\ feet.$ To calculate radius $(r)$ we will divide the diameter by two.

The radius of the cylinder would be $\frac{20}{2}=10\ feet$

Plug these values in the formula we get,

$\pi r^2h\\=\pi\times 10^2\times 3.5\\=3.14\times 100\times 3.5\\=1099\ ft^3$

Now, it is given $1\ ft^3 =7.5\ gal$

So, $1099\ ft^3 =1099\times 7.5\ gal=8242.5\ gal$

The swimming pool will contain approx $8243\ gal$ of water.

What is 10x-3>3x+11 as a word problem

Leokris [45]

Answer:

Ten times a number minus 3 is greater than three times the number plus eleven

Step-by-step explanation:

we have the inequality

10x-3 > 3x+11

Let

x ----> a number

As a word problem will be

10x -----> Ten times a number x

+ ----> plus

-3 -----> negative 3

> greater than

3x ----> three times a number x

11 ----> eleven

therefore

Ten times a number minus 3 is greater than three times the number plus eleven
