Answer:

Step-by-step explanation:

Mariam is making two types of paper lanterns. One type of flashlight needs 0.75 square feet of cardboard, while the other needs 1.15 square feet. If she made 5 of each type of flashlight, it means that

For the first type flashlight that she made, she used 0.75 × 5 = 3.75 square feet of cardboard.

For the second type of flashlight she made, she used 1.15 × 5 = 5.75 square feet of cardboard.

Total amount of cardboard used is

3.75 + 5.75 = 9.5 square feet

Mariam has 12.75 square feet of paper left over. Assuming the total square feet of cardboard that she used is x, then x = amount of cardboard used + the amount that is left over. It becomes

x = 9.5 + 12.75 = 22.25 square feet

She used 22.25 square feet

Find the missing length indicated <br> A) 25<br> B) 5<br> C) 8<br> D) 3
Nonamiya [84]

Given:

The figure of a triangle.

To find:

The missing length.

Solution:

Let x be the missing length.

Basic proportionality theorem(BPT): According to this theorem, if a line is parallel to the one side of a triangle then that the line intersects the other two sides of the triangle in the same ratio.

Using Basic proportionality theorem, we get

\dfrac{6}{8-6}=\dfrac{12-x}{x}

\dfrac{6}{2}=\dfrac{12-x}{x}

3=\dfrac{12-x}{x}

3x=12-x

Adding x on both sides, we get

3x+x=12

4x=12

x=\dfrac{12}{4}

x=3

The missing length is 3 Therefore, the correct option is D.

Answer:

A1) 125

A2) 47.5%

B) 30

Step-by-step explanation:

Remember 'of' in this sentence means times(*). % shows a certain number/100.

a1) 48% 'of' what number is 60?

(let unknown number be x)

48/100 *x=60

Solve the equation, and the answer is x=125

a2) what percentage 'of' 120 is 57?

(let the unknown percentage be x)

(x/100)*120=57

x=47.5%

b) 24 students= 80% of the total number of students

1%=24/80

100% of the total number of students=30

So, there are total of 30 students
