Answers

Answer 1

Uisng technology, such as a linear regression calculator or excel , the linear equation in slope - intercept format which models the data is 171.47x - 125.83

The relationship between advertising cost and e-commerce sales is positive which can be inferred from the positive value of the slope which models the data. Also, since, the correlation Coefficient is high, we can expect to have a high e-commerce sales whenever, the advertising cost is high.

Therefore, the linear regression equation is 171.47x - 125.83

Justice needs 24 feet of fencing to surround his garden. The fencing is priced at $0.25 per inch how much will it cost justice to fence in his garden?

Answers

Answer:

66 dollars

Step-by-step explanation:

Justice needs $72 to fence in his garden.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Justice needs 24 feet of fencing to surround his garden.

The fencing is priced at $0.25 per inch.

Since, 1 foot = 12 inch

Hence, 24 feet = 24 x 12 inch = 288 inch.

Cost of the fencing in one inch = $0.25

So, Cost of the fencing in 288 inch = 288 x 0.25

                                                      = $72

Thus, Justice needs $72 to fence in his garden.

Last year, the school library had a total of x books. Over the summer, the library acquired another 36 books and now has a total of 2,284 books. Which
equation could be used to find x, the number of books the library had last year

Answers

Answer:

the last year the eschool has 2248 books

Step-by-step explanation:

2284-36=2248

Answer:

2,248=2,284-36b

Step-by-step explanation:

since the library acquired(added) 36 books the library now has a total of 2,284 books.

To find out how many books the library had before they added 36 books you need to set up a simple equation.

2,284-36=2248

since you now know that before summer the library had 2,248 books you would write an equation and when you solve it you should get 2,248. The equation should be 2,248=2,284-36b. b representing the total number of books that were added.

Answer:I’m not sure if you had a file if so it’s not there but heres something else

Step-by-step explanation:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Step-by-step explanation:

The perimeter is calculated by multiplying the sum of width and height with 2

2*(4x-2+7x+9) = 300 solve inside the parenthesis

2*(11x+7) = 300 multiply inside the parenthesis with 2

22x + 14 = 300 subtract 14 from both sides

22x = 286 divide both sides by 22

Find the measure of two complementary angles if the measure of one is 15 degrees more than twice the measure of the other

Answers

Answer:

25 and 65

Step-by-step explanation:

Let one of the angles be x.

So, the other angle is 15 + 2x

complementary angles add up to 90 degrees.

so, we have

x + 2x + 15 = 90

3x + 15 = 90

Subtract 15 from both sides

3x = 75

solve for x

x = 25

so, the angles are 25 and 65

2 complementary angles sum up to 90°.

Take one angle as 'x'. Then, the other angle will be '15 + 2x'.

15 + 2x + x = 90°

15 + 3x = 90°

3x = 90 - 15

3x = 75

x = 75/3

x = 25°.

Measure of 1st angle (x°) = 25°

Measure of 2nd angle (15 + 2x°) = 15 + 2*25 = 65°.

=》 The 2 complementary angles are 25° & 65°.

Step-by-step explanation:

The length of a rectangular garden is 8 feet longer than its width. The garden's perimeter is 188 feet. Find the width of the garden.

Answers

Answer:

44 Feet

Step-by-step explanation:

Trust me

Answer:

Width = 43 feet

Step-by-step explanation:

Given the 188-feet perimeter of a rectangular garden, for which its length is 8 feet longer than its width:

We can express the length of the rectangular garden as: 8 + W.

Hence, in order to solve for the length and the width of the rectangular garden, use the following formula for the perimeter of a rectangle:

Perimeter (P) = 2(L + W) or 2L + 2W = 188 feet

Length (L) = 8 + W

Width (W) = W

Substitute these values into the perimeter formula to solve for the value of the rectangular garden's dimensions:

P = 2L + 2W

188 feet = 2(8 + W) + 2W

Distribute 2 into the parenthesis, (8 + W):

188 = 16 + 2W + 2W

Combine like terms:

188 = 16 + 4W

Subtract 16 from both sides:

188 - 16 = 16 - 16 + 4W

172 = 4W

Divide both sides by 4 to solve for W:

[tex]\LARGE\mathsf{\frac{172}{4}\:=\:\frac{4W}{4}}[/tex]

W = 43

Therefore, the width of a rectangular garden is 43 feet.  

Since we determined that the length is 8 + W, then it means that the length of the rectangular garden is 51 feet.

Verify the dimensions:

Double-check whether we have the correct dimensions for the rectangular garden by substituting the length (L) = 51 feet, and the width (W) = 43 feet, into the perimeter formula:

P = 2L + 2W

188 feet = 2(51) + 2(43)

188 feet = 102 + 86

188 feet = 188 feet  (True statement). This means that we have the correct dimensions for the rectangular garden.

Answers:

Therefore, the width of a rectangular garden is 43 feet.
