It's a ratio problem.

The ratio of boys to girls is 2:3

Since you know how many girls their are you plug it in

2:x

3:12

Basically you see how you get from 3 to 12 and the answer is to multiply by 4

Since it is a ratio problem you also multiply the 2 by 4

Travis needs to mail 4 letters and 10 postcards. A letter needs a 37-cent stamp and a postcard needs a 25-cent stamp. How much m

kifflom [539]

Answer:

398-cent stamp for postage.

Step-by-step explanation:

For one letter, Travis needs 37-cent stamp

For four letters, Travis needs 37-cent stamp x 4 letters

= 148-cent

Again,

For one postcard, he needs 25-cent stamp

For ten postcards, he needs 25-cent stamp x 10 postcards

= 250-cent

Therefore, he will spend = (148-cent + 250-cent) = 398-cent stamp for postage.

Need help please its my last question

Given:

Radius of circle = 12 units

Area of sector = 24π sq. units.

Central angle = x

To find:

The value of x.

Solution:

We have,

$r=12$

$A=24\pi$

$\theta = x$

We know that, area of a sector is

$A=\dfrac{\theta }{360^\circ}\pi r^2$

Where, $\theta$ is central angle, r is radius.

$24\pi=\dfrac{x}{360^\circ}\pi (12)^2$

$24\pi=\dfrac{x}{360^\circ}\pi (144)$

$\dfrac{24\pi}{144\pi}=\dfrac{x}{360^\circ}$

$\dfrac{1}{6}=\dfrac{x}{360^\circ}$

Multiply both sides by 360 degrees.

$\dfrac{1}{6}\times 360^\circ=x$

$60^\circ=x$

The value of x is 60 degrees.

Therefore, the correct option is A.

The YMCA lap pool is a right rectangular prism 36.8\, \text{m}36.8m36, point, 8, start text, m, end text long by 20 \,\text{m}20

Volume is a three-dimensional scalar quantity. The depth of the YMCA lap pool is 2 meters.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given that the following details about the YMCA lap pool:

The volume of the pool = 1472m³
The length of the pool = 36.8m
The width of the pool = 20 m

Since the pool is in the space of a right rectangular prism, therefore, the volume of the prism will be the product of length, width and depth. Therefore, the volume of the pool can be written as,

The volume of the pool = Length × width × depth

1472m³ = 36.8m × 20 m × depth of the pool

Depth of the pool = (1472m³ ) / (36.8m × 20m)

= 2 meter

Hence, the depth of the YMCA lap pool is 2 meters.

Answer:

20/9

Step-by-step explanation:

Alright, so by using the "keep me, change me, turn me over" method - we can easily solve this:

$\frac{8}{9}\div \frac{2}{5}\\=\frac{8}{9}\times \frac{5}{2}\\=\frac{4}{9}\times \frac{5}{1}\\=\frac{4\times \:5}{9\times \:1}\\=\frac{20}{9}$
