Samuel is a teacher and takes home 75 papers to grade over the weekend. He can grade at a rate of 7 papers per hour. How many papers would Samuel have remaining to grade after working for 8 hours?

Answers

Answer: 19

Step-by-step explanation:

75 papers need to be marked

He grades 7 papers per hour

To find out how many paper he graded in 8 hours:

7 x 8

(7 is the number of papers graded in an hour)

(8 is the number of hours)

7 x 8 = 56

(56 is the number of papers he graded in 8 hours)

Now, there was a total of 75.

To find the remaining number of test sheets:

75 - 56

(75 is the total number of papers)

(56 is the number of papers graded)

75 - 56 = 19

Therefore, there are 19 papers remaining to grade.

Ray is a member of a card club. He pays a fixed fee of $45. He must pay $6 for every game he attended. He attends 12 games. What is the total amout that he payed

Answers

Answer:

$117

Step-by-step explanation:

Create an equation to represent the situation, where x is the number of games he attended, and y is the cost

y = 6x + 45

Solve for the amount he paid by plugging in 12 as x

y = 6x + 45

y = 6(12) + 45

y = 72 + 45

y = 117

So, Ray paid $117

Determine the radius of the circle below.

Answers

Answer:

r = 22.629

Step-by-step explanation:

Using the Pythagorean theorem:

(35 + r)² = 53² + r²

1225 + 70r + r²  = 2809 + r²

subtract r² from each side of the equation:

1225 + 70r = 2809

subtract 1225 from each side:

70r = 1584

r = 22.629

The area of a sector is. What does the variable n represent?

Answers

the number of degree in the central angle

N is the degree of the central angle of the sector.

What is sector in an angle?

The sector angle is the angle subtended between two radii of circle to the center of Circle.

If the radius of the circle is 10 inches, and the central angle of the sector is 90 degrees, the area of the sector can be found as follows:

90/360 * (3.14 * 10^2).

Following the order of operations, the equation proceeds as follows:

1/4 * (3.14 * 100) = 1/4 * 314 = 78.5.

Thus, the area of the sector is 78.5 square inches.

The formula to find the area of a sector is A = N/360 x (pi x r^2).

A sector is a section of a circle. In the formula given, A is the area of the sector,

N is the degree of the central angle of the sector, pi is an irrational number that can be rounded to 3.14, and r is the length of the radius of the circle.

Hence,  N is the degree of the central angle of the sector.

The width of a rectangle is 7 feet and the diagonal legnth of the rectangle is 11 feet. Which measurement is closest to the length of this rectangle in feet?

Answers

Answer:

8.49 feet

Step-by-step explanation:

Characteristics of a rectangle

A rectangle is a quadrilateral It has two parallel sides the diagonals of a rectangle bisect each other and they are equal in length

One diagonal of a rectangle divides a rectangle into two right angled triangles. Thus, the length of the rectangle can be determined using the Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length = ?

b = width = 7

c = diagonal = 11

7² + a² = 11²

49² + a² = 121²

a² = 121 - 49

a² = 72

calculate the square root of 72

a = 8.49 feet

Answer:

8.49 feet

Todd uses white tiles and some black tiles to make mosaic the mosaic has a total area of 144 square centimeters each tile has an area of 3 square centimeters how many black tiles did Todd use

Answers

Answer:

27 tiles

Step-by-step explanation:

Here is the complete question :

Todd uses 21 white tiles and some black tiles to make a mosaic.the mosaic has a total area of 144 square centimeters. Each tile has an area of 3 square centimeters. How many black tiles did Todd use

Steps to take to determine the answer

Determine the total area of the white tiles used. This can be determined by multiplying the number of white tiles by the area of a tilesubtract the area of the white tiles from the total area of the mosaic. Divide the answer derived in the previous step by 3

Area of the white tile = area of each tile x total white tiles used

3 x 21 = 63cm²

144cm² - 63cm² = 81cm²

Number of black tiles used = 81cm² / 3cm² = 27 tiles

Which graph below shows the rule: output = 5 times input?

Answers

Given:

Output = 5 times input

To find:

The graph for the given statement.

Solution:

We know that, y-axis represents the output and x-axis represents the input.

Let y be the output and x be the input. Then the given statement can be written as

[tex]y=5x[/tex]

Here, the slope of the line is 5 because the value of [tex]m[/tex] is 5 on comparing the equation with [tex]y=mx+b[/tex].

It means the line is steeper because the vertical change is greater than the horizontal change.

Therefore, the correct option is A.

Maynard Shephard, the recently hired assistant controller, has been asked to develop a cost function to forecast shipping costs. The previous assistant controller had forecast shipping department costs each year by plotting cost data against direct labor-hours for the most recent 12 months and visually fitting a straight line through the points. The results were not satisfactory.After discussions with the shipping department personnel, Maynard decided that shipping costs could be more closely related to the number of orders filled. He based his conclusion on the fact that 10 months ago the shipping department added some automated equipment. Furthermore, he believes that using linear regression analysis will improve the forecasts of shipping costs. Cost data for the shipping department have been accumulated for the last 25 weeks. He ran two regression analyses of the data, one using direct labor-hours, and one using the number of cartons shipped. The information from the two linear regressions follows: Regression 1 Regression 2Equation SC = 804.3 + 15.68DL SC = 642.9 + 3.92NRR-squared .365 .729Standard error of the estimate 2.652 1.884t-value 1.89 3.46where:SC = total shipping department costs DL = total direct labor-hoursNR = number of cartons shippedRequired1.

Explain two or three important limitations of the regression you selected in requirement 1, and identify one or two ways to address the limitations.
