Tim worked for a total of 7 and half hours on Monday and earned $56.25 gross pay.

What is gross pay and net pay?

Prior to payroll deductions, earned wages are referred to as gross pay. Employers utilize this amount—$60,000 per year or $25 per hour—when talking to employees about pay. Additionally, the federal and state income tax brackets sometimes refer to gross salary.

The amount of pay that employees get after payroll deductions varies; some may be optional, while others may be required.

Given, On Monday of his time card Tim clocked in at 8:15 am and clocked out at 4:15 pm.

So, The total number of hours she worked is 8 hours, 8:15 to 12:15 is 4 hours, and another four hours.

Also given the time he took for lunch is half an hour.

Therefore, The total hour he worked is 7:30 hours.

He earns $7.5 per hour so his gross pay for Monday is $(7.5×7.5).

= $56.25.

Show how to use the unit rate to find the missing numbers on the double number line

Answers

Using the Double Number Line above, note that the unit that helps to find the missing numbers is given as:

3 and 915 and 518 and 624 and 827 and 9.

What is a Unite Rate and How does it relate to a Double Number Line?

Note that a unit rate is like a secret code to help you compare things. It helps you find missing numbers on a number line. For example, if 4 cookies cost $2, you can use the unit rate of $0.50/cookie to find out how much 8 cookies cost."

In the above case, we have several clues about the rate. The first relationship on the line is between 1 and 3.

But it only makes when we compare it to other iterations on the line such as 2 and 6.

Note that we can establish a relationship here which is that the greater number must be divided by three to get the lower number. That is:

3/3 = 1

6/3 = 2

Note well that the relationship between 0, 3, and 6 on the number line tell us that the upper units graduate in progressions of 3. that is:

0, 3, 6, 9, etc.

Thus, the missing numbers are:

3 and 915 and 518 and 624 and 827 and 9

Find the volume of the composite solid. Round your answer to the nearest hundredth.

Answers

Answer:

9,114.81 ft³

Step-by-step explanation:

The solid is composed of a cylinder and a hemisphere

Volume of the solid = volume of the cylinder + volume of the hemisphere

= πr²h + ⅔πr³

Where,

r = 8 ft

h = 40 ft

Plug in the values into the equation

Thus:

Volume of the solid = π*8²*40 + ⅔*π*8³

= 8,042.4772 + 1,072.33029

= 9,114.80729

= 9,114.81 ft³ (nearest hundredth)

Step-by-step explanation:

I'm sorry if it isn't right

Answer:  30

===========================================================

Explanation:

Each tickmark on the graph represents a distance of 2 units. From A to P is 4 tickmarks, so that corresponds to 2*4 = 8 units. That's one of the bases. The other base is TR = 2. The bases are parallel to one another.

The height is always perpendicular to the base, and the height is 2*3 = 6 units.

So we have

b1 = 8, b2 = 2, and h = 6

Which means,

A = h*(b1+b2)/2

A = 6*(8+2)/2

A = 6*10/2

A = 60/2

A = 30

------------------------------

As a slightly longer alternative, we can plot points at (-2, 0) and (-2, -2). Let's call these two points M and N respectively. These two points subdivide the trapezoid into three pieces: Two triangles sandwiching a rectangle.

Triangle TMP has area of base*height/2 = 6*4/2 = 12Rectangle TMNR has area of length*width = 6*2 = 12Triangle RNA has area of base*height/2 = 6*2/2 = 6

Add up those sub-areas to get the full area of the trapezoid:

12+12+6 = 30

b. Interpret each of the estimated regression coefficients of the regression model.
c. Is the founder of the company correct in believing that the price received for the item increases with its age and with the number of bidders? Explain your answer.

Answers

Solution :

a). The required linear regression model is

Price = [tex]$-1242.986 + 75.017 \times \text{age of part} + 13.973 \times \text{ number of bidders}$[/tex]

b). The [tex]$\text{p-value}$[/tex] for the variable "Age of part" is 0.0000

Since the [tex]$\text{p-value}$[/tex] is less than 0.05, so it is significant to the model.

The p-value for the variable "Number of bidders" is 0.1940

Since [tex]$\text{p-value}$[/tex]  is not less than [tex]$0.05$[/tex], so it is significant to the model.

c). We cannot say that model is significant because variable " the number of bidders" is not significant.

But as both variables have positive coefficient so as the variable increases the price received for the item also increased.

Akira is setting tables at the restaurant where she works. She starts with a pile of 85 napkins, and she places 6 napkins on every table she sets

Write an equation that shows how the number of napkins remaining, y, depends on the number of tables akira sets, x

Answers

Answer: y = 85 - 6x

Step-by-step explanation:

Number of napkins remaining: y

Jane's monthly payment this year using balance billing would be $164 per month.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

To determine Jane's monthly payment this year using balance billing, we need to divide the total amount she spent last year ($1,968) by the number of months in a year.

Total amount spent last year = $1,968

Number of months in a year = 12

So, Monthly payment = Total amount spent last year / Number of months in a year

Monthly payment = $1,968 / 12

Monthly payment ≈ $164

Therefore, Jane's monthly payment this year using balance billing would be $164 per month.

17. Identify the amplitude, period, and vertical shift for the
function shown. Then write an equation that represents the curve.
m
A=
B=
P=
C=
f(x)=

Answers

Answer:

[tex]f(x)=2cos(x+\frac{\pi}{2})+3[/tex]

Step-by-step explanation:

Because the function is symmetric about the y-axis, using the cosine function is most appropriate.

Refer to the equation for a cosine function:

[tex]f(x)=acos(bx+c)+d[/tex]

Amplitude: [tex]|a|[/tex]

Period: [tex]\frac{2\pi}{|b|}[/tex]

Phase shift: [tex]-\frac{c}{b}[/tex]

Midline: [tex]y=d[/tex]

The amplitude would be the average of the maximum and minimum y-values of the function, which would be [tex]|a|=|\frac{5-1}{2}| =|\frac{4}{2}| =|2|=2[/tex].

The value of [tex]b[/tex] in [tex]\frac{2\pi}{|b|}[/tex] represents the length of the period, so since the length of the period is [tex]2\pi[/tex], this means that [tex]b=\frac{2\pi}{|2\pi|} =1[/tex].

The phase shift, [tex]-\frac{c}{b}[/tex], describes the horizontal shift of a function. Because the phase shift is [tex]-\frac{\pi}{2}[/tex], then we can set up the equation [tex]-\frac{\pi}{2}=-\frac{c}{1}[/tex] where we determine [tex]c=\frac{\pi}{2}[/tex].

The midline (or vertical shift), [tex]d[/tex], is the horizontal line that passes through between the maximum and minimum points, which the function oscillates. In this case, the midline would be located at the line [tex]y=3[/tex], therefore, [tex]d=3[/tex].

Putting all our information together, your final equation is:

[tex]f(x)=2cos(x+\frac{\pi}{2})+3[/tex]

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Kala got a prepaid debit card with $15.

Price of Ribbon = 24 cents per yard.

Answer:

60

Step-by-step explanation:

The measure of ∠ATS is 120. The measure of a straight angle is always going to be 180 degrees. So first, we subtract 120 from 180 to find the measure of the interior angle.

∠STR = 180 - 120

The measure of all the interior angles in the triangle ΔSTR is 180 degrees.

180 - 60 - 60
