So since they are vertical angles they’d be congruent or the same measure. So you would set it equal together like this 75=4x - 5. Add 5 to both sides 80=4x. Divide by 4 and x is 20

3. 36 percent of 18 is 18 percent of what number?

Fiesta28 [93]

Answer:

The required number is 3.36.

Step-by-step explanation:

To find : 3.36 percent of 18 is 18 percent of what number?

Solution :

Let the required number be 'x',

According to question,

3.36 percent of 18 is 18 percent of x,

i.e. $3.36\%\times 18=18\%\times x$

$\frac{3.36}{100}\times 18=\frac{18}{100}\times x$

$x=\frac{3.36\times 100}{100\times 18}\times 18$

$x=3.36$

So, 3.36 percent of 18 is 18 percent of 3.36,

Therefore, The required number is 3.36.

tatyana61 [14]

Answer: $1\frac{1}{4}\ cups$ is needed for 5 servings.

Step-by-step explanation:

Since we have given that

Hemal wanted to make desert for her family for which they made the recipe,

For 8 servings , the number of cups of flour is needed = 2

We will use "Unitary Method" ,

For 1 serving, the number of cups of flour is needed is given by

$\frac{2}{8}=\frac{1}{4}$

For 5 servings, the number of cups of flour is needed is given by

$\frac{1}{4}\times 5=\frac{5}{4}=1\frac{1}{4}\ cups$

Hence, $1\frac{1}{4}\ cups$ is needed for 5 servings.

Given the pair of triangles are similar find the unknown length of the sides labeled with a variable

MArishka [77]

Answer:

The answer is below

Step-by-step explanation:

The question is not complete. Let us assume the following:

Let us assume triangle ABC is a right angled triangle with side AB = 24, AC = 32 and the hypotenuse BC = 40. Triangle PQR is a right angled triangle similar to triangle ABC with side PQ = 27, PR= b and the hypotenuse QR = a.

Answer:

Two triangles are said to be similar if they have proportional angles or proportional sides that is they have the same shape. For similar triangles, the ratio of their corresponding side are the same.

Given that triangle ABC is similar to triangle PQR, therefore:

$\frac{AB}{AC}=\frac{PQ}{PR}\\ Substituting:\\\frac{24}{32}=\frac{27}{b}\\cross\ multiplying:\\b=\frac{27*32}{24}\\ b=36$

$\frac{AB}{BC}=\frac{PQ}{QR}\\ Substituting:\\\frac{24}{40}=\frac{27}{a}\\cross\ multiplying:\\a=\frac{27*40}{24}\\ a=45$
