If 30 buses can carry 1,500 people, how many people can 5 buses carry? A 200 © 500 B 250 D 750​
maksim [4K]

Answer:

\boxed {\boxed {\sf 250 \ people}}

Step-by-step explanation:

Let's set up a proportion using the following setup.

\frac {buses}{people}=\frac {buses}{people}

We know 30 buses can carry 1,500 people.

\frac {30 \ buses}{1500 \ people}=\frac {buses}{people}

We don't know how many people 5 buses can carry, so we say 5 buses carry x people.

\frac {30 \ buses}{1500 \ people}=\frac {5 \ buses}{x \ people}

\frac {30 }{1500 }=\frac {5 }{x }

Cross multiply. Multiply the numerator of the first fraction by the second fraction's denominator. Then, multiply the first denominator by the second numerator.

30*x=1500*5\\30x=7500

Solve for x. It is being multiplied by 30. The inverse of multiplication is division. Divide both sides by 30.

30x/30=7500\\x=250

5 buses can carry 250 people.

The diameter of Joe's large pizza is 19 inches. Approximately how many inches are there in the circumference of the large pizza?
Burka [1]

Answer:

There are 59.66 inches in the circumference of the large pizza.

Step-by-step explanation:

It is given that:

Diameter of Joe's large pizza = 19 inches

Diameter = 2r

2r = 19

Circumference of large pizza = 2πr = 2r * π

Circumference of large pizza = 19*3.14

Circumference = 59.66 inches

Therefore,

There are 59.66 inches in the circumference of the large pizza.

The perimeter of the triangular park shown on the right is 10x - 3. What is the missing length?
viva [34]

Answer:

6x - 1

Step-by-step explanation:

Okay this is basically polynomial algebra:

1. Add the value of the lengths already given.

like terms: 3x + x = 4x, -4 + 2 = -2. Now you're left with, 4x - 2.

2. Find the difference between the perimeter and the sum of the lengths.

(10x -3) + (4x + 2) = 6x - 1
