What is 45 percent as a fraction

2 answers:

45% as a fraction would just be 45/100 because a fraction is just adding a 100 to make a denominator. (Only in the case of changing a percent to a fraction) If you choose the simplify your answer then the fraction would be <span>9/20</span>.

Hello There!

45% as a fraction is $\frac{9}{20}$

45% = $\frac{45}{100}$

45 ÷ 100 = 0.45

$\frac{0.45}{1}$ X $\frac{100}{100}$ = $\frac{45}{100}$

REDUCED: $\frac{9}{20}$

Harry saved $100 each week for 8 weeks. He earned $48 on his savings of $800. What interest did Harry earn for every $100?

ch4aika [34]

<h2>Explanation:</h2><h2></h2>

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

$\text{Amount of money saved}=8\times 100=\$800$

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

$I=\frac{48}{8}=\$6$

So, in conclusion Harry did earn $6 in interest for every $100

Johnny's town is having an old-fashioned circus under a large tent. In order to keep the tent from falling down, workers must ti

Zepler [3.9K]

Answer: 62 feet approximately.

Step-by-step explanation:

1. Based on the information given in the problem, you can draw a right triangle as the one shown in the image attached, where the height of the tent is represented with $x$ . Therefore, you can calculate it as following:

$sin\alpha=\frac{oppostite}{hypotenuse}$

Where:

$\alpha=62\°\\opposite=x\\hypotenuse=70$

2. Substitute values and solve for $x$ , then the height of the circus tent is:

$sin(62\°)=\frac{x}{70}\\x=70*sin(62\°)$

$x=61.81$ ≈ $62ft$

Quadrilateral ABCD is inscribed in a circle. m∠A is 64°, m∠B is (6x + 4)°, and m∠C is (9x − 1)°. What is m∠D?

Flauer [41]

Answer:

The m∠D is 98° ⇒ answer D

Step-by-step explanation:

* Lets revise some facts in the circle

- The quadrilateral is inscribed in a circle if its four vertices lie on the

circumference of the circle

- It is called a cyclic quadrilateral

- Every two opposite angles in it are supplementary means the

sum of their measures is 180°

∵ ABCD is inscribed in a circle

∴ ABCD is a cyclic quadrilateral

∵ ∠A and ∠C are opposite angles in the cyclic quadrilateral ABCD

∴ ∠A and ∠C are supplementary

∴ m∠A + m∠C = 180°

∵ m∠A = 64°

∵ m∠C = (9x - 1)°

∴ 64 + (9x - 1) = 180 ⇒ simplify

∴ 63 + 9x = 180 ⇒ subtract 63 from both sides

∴ 9x = 117 ⇒ divide both sides by 9

∴ x = 13

- Lets find the measure of ∠B

∵ m∠B = (6x + 4)°

∵ x = 13

∴ m∠B = 6(13) + 4 = 78 + 4 = 82°

- Lets find the measure of ∠D

∵ ∠B and ∠D are opposite angles in the cyclic quadrilateral ABCD

∴ ∠B and ∠D are supplementary

∴ m∠B + m∠D = 180°

∵ m∠B = 82°

∴ 82° + m∠D = 180° ⇒ subtract 82° from both sides

∴ m∠D = 98°

* The m∠D is 98°

What is the value of x in the following equation: x - 2 = 9?<br> (please and thank you!!!)

Anit [1.1K]

AnswEr:

Add the two, to both sides. -2+2=0

So, the equation would like like this

x -2= 9

+2 +2

Then solve, the 2’s cancel out leaving you with x by itself. Finishing the equation to look like this-> x=11
