Ralph’s annual expenses for the upcoming year are summarized in the chart below. Based on the information in the graph, approximately what percent of his total annual income is Ralph having withheld for taxes?
a. 6%
b. 18%
c. 30%
d. 36%

Answers

Answer:

D

Step-by-step explanation:

You have to do the summation of all expenses so

1,750+3,260+3,500+4,332+6,652+4,880+15,000+3,448+18,380= 61,202

The total of taxes is composed of state taxes and federal taxes

3,448+18,380= 21,828

Set up a proportion to calculate the percentage

21,828 : 61,202 = x% : 100%

[tex]x\% = \frac{21828 \times 100}{61202} = \frac{2182100}{61202} = 35.67\%[/tex]

You can approximate the result to 36%

The percentage of the annual budget withheld for taxes is 36%.

Total budget of Ralph

The total budget of Ralph is calculated as follows;

T = 1,750 + 3,260 + 3,500 + 4,332 + 6,652 + 4,880 + 15,000 + 3,448 + 18,380

T = $61,202

Total tax on Ralph's annual budget

Tax = 3,448 + 18,380

Tax = $21,828

The percentage of the annual budget withheld for taxes is calculated as follows;

[tex]= \frac{tax}{total \ budget} \times 100\%\\\\= \frac{21,828}{61,202} \times 100\%\\\\= 35.67 \ \%\\\\\approx 36 \ \%[/tex]

Jamal spent _ 3 4 of his allowance. On the number line, label the fraction that represents the part that Jamal spent. Explain

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Fraction of pocket money spent by Jamal = 3/4

The number line is divided into 4 equal parts with distance between successive tick marks representing 1 of the whole = (1/4). Hence, 3/4 of the whole would mean 3 portions of the total 4 portions of the number line represents the amount spent by Jamal.

The common prime factor of the numbers  77 and 242? will be 11.

What is a prime factor?

A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,

Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,

77 / 11 = 7

242 / 11 = 22

Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.

Find the three trigonometric..pls help due very soon

Answers

Answer:

sin 0 = 24/25

cos 0 = 7/25

tan 0 = 24/7

Step-by-step explanation:

hey there!

sine = opposite divided by hypotenuse

the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25

cosine = adjacent divided by hypotenuse

the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25

Tangent.= opposite divided by adjacent

the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7

What is the value of x?

Answers

The value of x is 13

Answer:

135°

Step-by-step explanation:

here's your solution

=> we know that , sum of all angles is

equal to 180°

=> hence ,we have two angles

=> 1st angle = 45°

=> 2nd angle = 9x + 18

=>. adding both angle

=> 45° + 9x + 18° = 180°

=> 63° + 9x = 180°

=> 9x = 180° - 63

=> 9x = 117°

=>. x = 117/9

=> x = 13°

=>. hence, the required angle = (13*7) + 18°

=> angle = 135°
