Answer:

Step-by-step explanation:

More than one triangle can be formed by three angles measuring 75°, 45° and 60°. Solution : We know that, The sum of the measures of all angles of a triangle should be equal to 180°. Hence, the angles 40° , 50° and 60° cannot form a triangle as their sum is 150°.

Applications with Decimals

tresset_1 [31]

$Fraction = \frac{36}{48}$

$Decimal = 0.75$

$Percent = 75 \%$

<em><u>Solution:</u></em>

Given that,

36 rainy days out of 48 days

<h3><u>Find the fraction:</u></h3>

numerator = 36

denominator = 48

Therefore,

$Fraction = \frac{36}{48}$

<h3><u>Decimal:</u></h3>

Convert the fraction to decimal:

$Decimal = \frac{36}{48} = 0.75$

<h3><u>Percent:</u></h3>

We have to find the percent pf 36 rainy days out of 48 days

$Percent = \frac{36}{48} \times 100\\\\Percent = 0.75 \times 100\\\\Percent = 75 \%$

Thus percent is 75 %

Item 16 A sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. What is the difference of the vol

Zigmanuir [339]

Answer:

$672\pi \text{ cm}^3$ .

Step-by-step explanation:

We have been given that a sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. We are asked to find the difference of the volumes of the spheres.

We will use volume formula of sphere to solve our given problem.

$\text{Volume of sphere}=\frac{4}{3}\pi r^3$ , where r is radius of sphere.

The difference of volumes would be volume of larger sphere minus volume of smaller sphere.

$\text{Difference of volumes}=\frac{4}{3}\pi(\text{8 cm})^3-\frac{4}{3}\pi(\text{2 cm})^3$

$\text{Difference of volumes}=\frac{4}{3}\pi(512)\text{ cm}^3-\frac{4}{3}\pi(8)\text{ cm}^3$

$\text{Difference of volumes}=\frac{4}{3}\pi(512-8)\text{ cm}^3$

$\text{Difference of volumes}=4\pi(168)\text{ cm}^3$

$\text{Difference of volumes}=672\pi\text{ cm}^3$

Therefore, the difference between volumes of the spheres is $672\pi \text{ cm}^3$ .
