Marianne's withholding tax if her monthly gross earnings are $3,270 is $305.00.

The correct option is A.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Brittany works as a medical office assistant.

She is married and claims 2 withholding allowances.

Her monthly gross earnings are $3,270.

So, 3270 - 2(666.5) = $1937.3

So,

(1937.3 x 0.15) + 14.49 = $305.00

Therefore, the value is $305.00.

The possible value for the original number is 30

Represent the number with n

So, we have

Lacey = 10 * (n/10 + 1/2)

Euan = 100 * (n/100 + 1/2).

Also, Lacey's new number is 3/4 of Euan's new number, so we have:

10 * (n/10 + 1/2) = (3/4) * (100 * (n/100 + 1/2))

Solving for n, we have:

100 * (n/100 + 1/2) = (4/3) * (10 * (n/10 + 1/2))

Divide through by 100

n/100 + 1/2 = (4/30) * (n/10 + 1/2)

Evaluate

(n + 50)/100 = 4n/300 + 2/30

So, we have

n + 50 = 4n/3 + 20/3

Multiply through by 3

3n + 50 = 4n + 20

Evaluate the like terms

n = 30

Hence, the original number is 30

sin70 = x/3.6

x = 3.6sin70

x = 3.4

Answer:

x = 3.4

Step-by-step explanation:

As the given triangle is a right triangle we can use trigonometric ratios to solve for x.

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

From inspection of the triangle:

As we know the angle and the hypotenuse, and wish to find the side opposite the angle, substitute the values into the sine ratio and solve for x:

[tex]\implies \sin(70^{\circ})=\dfrac{x}{3.6}[/tex]

[tex]\implies x=3.6\sin(70^{\circ})[/tex]

[tex]\implies x=3.382893...[/tex]

[tex]\implies x=3.4\; \sf (nearest\;tenth)[/tex]

Therefore, x = 3.4 to the nearest tenth.

The percentage of expenditure which goes towards salaries is 78%

Company's expenditure:

Salaries: R105 000 000

Equipment: R10 000 000

Marketing: R2 000 000

Other: R8 000 000

Total expenditure= R105 000 000 + R10 000 000 + R2 000 000 + R8 000 000

= R135,000,000

percentage of the expenditure is salary= R105 000 000 / R135,000,000 × 100

The four possible times that car B could take to complete one lap are: 120 seconds, 90 seconds, 60 seconds, and 30 seconds.

The equation used to solve this problem is (150 - 30) = N * B, where N is the number of laps and B is the total number of seconds for car B to complete one lap. Therefore, the four possible times for car B to complete one lap are 120 seconds, 90 seconds, 60 seconds, and 30 seconds.

When solving for the total time, it is important to remember that the two cars start the race together and that their speeds remain constant. This means that the time it takes for car B to complete one lap must be a factor of 150 seconds. If car B takes a time that is not a factor of 150, then it will not be able to finish the race in 150 seconds.

And the perimeter is given as,

P = 2(L + W)

A rectangle has a width-to-height ratio of 8:5. The perimeter of the rectangle is 208 inches. Then the equations are given as,

208 = 2(W + H)

H + W = 104                ...1

To find the probability of randomly withdrawing 5 jellybeans such that at least 2 are red, we need to find the total number of ways to select 5 jellybeans from the bag and then find the number of ways to select 2 or more red jellybeans.

Let's first find the total number of ways to select 5 jellybeans from the bag:

Total number of jellybeans = 4 red + 7 green = 11 jellybeans

Number of ways to select 5 jellybeans from 11 = 11 choose 5 = 462

Next, we need to find the number of ways to select 2 or more red jellybeans:

Number of ways to select 2 red jellybeans = 4 choose 2 = 6

Number of ways to select 3 red jellybeans = 4 choose 3 = 4

Number of ways to select 4 red jellybeans = 4 choose 4 = 1

Total number of ways to select 2 or more red jellybeans = 6 + 4 + 1 = 11

The desired probability is the ratio of the number of favorable outcomes (selecting 2 or more red jellybeans) to the total number of possible outcomes (selecting 5 jellybeans):

P(at least 2 red) = 11/462 = 11/462 = 0.0239 or 2.39%

So, the probability of randomly withdrawing 5 jellybeans such that at least 2 are red is 2.39%.

The game with 8 minutes of time-outs is 98 minutes long.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations such as addition, subtraction, multiplication, and division.

In this case, the algebraic expression that represents the length of the soccer game would be:

m = 90 + x

where m represents the total length of the game in minutes, 90 represents the fixed length of the game, and x represents the variable length of time-outs in minutes.

To find the length of the game with 8 minutes of time-outs, we substitute x = 8 into the expression:

m = 90 + 8 = 98

Therefore, the game with 8 minutes of time-outs is 98 minutes long.

Answer:

Genesis has 126 different outfits to choose from.

Step-by-step explanation:

To calculate the total number of different outfits Genesis can choose, we need to multiply the number of choices available for each article of clothing. So we have:

7 choices for pants

2 choices for t-shirts

3 choices for sweaters or hoodies

3 choices for shoes

To find the total number of outfits, we multiply the number of choices for each category:

7 x 2 x 3 x 3 = 126

Therefore, Genesis has 126 different outfits to choose from.

126 different combination does Genesis have to choose.

We have,

Pants = 7

T shirts = 2

Sweaters or Hoodies = 3

Shoes = 3

So, the number of different combination is

= C(7, 1) x C( 2, 1) x C(3, 1) x C(3, 1)

= 7 x 2 x 3 x 3

Let the second segment crosses at (a,0) on the X-axis:

The area under the density curve is 1.

the given fig can be divided into a rectangle and a triangle by dropping a line from the point (0.5, 1) in the x-axis.

The coordinate point of the second segment at the x-axis:

Now,

1*0.5+1/2*1*(a-0.5)=1

1+(a-0.5)=2

a-0.5=2-1

a=1+0.5

a=1.5

Thus the second segment crosses the x-axis at (1.5, 0)

The slope of that segment c:

The slope  of that segment=y₂-y₁/x₂-x₁

By considering the points (0.5, 1) and (1.5, 0)

We will have the slope as:

m=0-1/1.5-0.5

m=-1/1

m=-1

the equation of the line containing this segment:

The line passes from the point (0.5, 1)

y=mx+b is used to find the value of the intercept

Answer:

The volume of the rectangular prism can be calculated by multiplying its length, width, and height: 8 x 4.12 x 3.12 = 128.064 cubic inches.

Answer:

V=342,784in

Step-by-step explanation:

V=1/3(L×W×H)

where v=volume of rectangular prism,L=length.W=width or breadth,H=height

V=1/3×8×412×312

V=342,784in

Answer:

The volume of one marble can be calculated as follows:

V = (4/3) * π * (r^3)

where r = 1.25 cm (diameter of 2.5 cm divided by 2)

V = (4/3) * 3.14 * (1.25^3) = 5.20 cm^3

The mass of one marble is then:

m = V * 2.6 g/cm^3 = 13.52 g

And the total mass of 66 marbles is:

m = 66 * 13.52 g = 888.32 g

Rounding to the nearest gram, the total mass of the marbles in Keisha's pouch is 888 g.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200

⇒ 0.5x = 1200

⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400

250% of p = 2400

2.5p = 2400

p = 2400 / 2.5 = 960.
