Which expression is equivalent to the expression for the perimeter of the larger garden. Select all the apply.

Answers

Answer:

Option A, 4X + 40 expression is equivalent to the expression for the perimeter of the larger garden

Step-by-step explanation:

The complete question is

A garden is 15 feet long by 5 feet wide. The length and width of the garden will each be increased by the same number of feet. This expression represents the perimeter of the larger garden: (x+15)+(x+5)+(x+15)+(x+5). Which expression is equivalent to the expression for the perimeter of the larger garden? Select all that apply.

4x+40 2(2x+20) 2(x+15)(x+5) 4(x+15)(x+5) 2(x+15)+2(x+5)

Solution

The expression for the perimeter of the larger garden: [tex](x+15)+(x+5)+(x+15)+(x+5)[/tex]

If the given expression is expanded and solved, we get the following

[tex](x+15)+(x+5)+(x+15)+(x+5)\\X+X+X+X + 15+15+5+5\\2X+2X+30+10\\4X +40[/tex]

Hence, option A is correct

Does anyone know what 9x*3x/4 is?

Answers

Answer and Step-by-step explanation:

We are given the expression [tex]\frac{9x * 3x}{4}[/tex].

First, we need to multiply 9x by 3x. This results us with [tex]27x^2[/tex].

[tex]\frac{27x^2}{4}[/tex] -- This is the final expression simplified. There isn't anything else we can do this expression, as it is not factorable and can't be simplified any further.

A scale of 1 cm to 8 km is used for a map.
(i) If a forest has an area of 5 cm² on the map, find its actual area.
(ii)
If the actual area of a park is 128 km², calculate its area on the map.​

Answers

Answer:

40 km^2

16 cm^2

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Actual area = scale factor x scaled area

8 x 5 = 40 km^2

Scaled area on the map = 128.8 = 16 cm^2

State study on labor reported that one-third of full-time teachers in the state also worked part-time at another job. For those teachers, the average number of hours worked per week at the part-time job was 13. After an increase in state teacher salaries, a random sample of 400 teachers who worked part-time at another job was selected. The average number of hours worked per week at the part-time job for the teachers in the sample was 12.5 with a standard deviation of 6.5 hours. Is there convincing statistical evidence, at the level of α=0.05, that the average number of hours worked per week at part-time jobs decreased after the salary increase?
(A) No. The p-value of the appropriate test is greater than 0.05.
(B) No. The p-value of the appropriate test is less than 0.05.
(C) Yes. The p-value of the appropriate test is greater than 0.05.

Answer:

B - No. The p-value of the appropriate test is less than 0.05

Step-by-step explanation:

I found it online in some answer key pdf

From the solution to the question that we have here, the answer is A. There is no convincing evidence that the hours worked decreased after the increase in salary.

The hypothesis formulation

H0: u = 13

H1: u < 13

sample size n = 400

bar x = 12.5

mean = 13

How to solve for the t test statistics

[tex]t = \frac{x-u}{s/\sqrt{n} } \\\\t = \frac{12.5-13}{6.5/\sqrt{400} } \\[/tex]

= -1.5388

degree of freedom: 400 -1 = 399

∝ = 0.05

Find the p value

p(t < -1.5385)

= 0.062

The p value is greater than the level of significance. We therefore fail to reject the null hypothesis.

In this figure shown, EF is the mid segment of trapezoid ABCD. Find EF.

Answers

Answer:

x = 2

Step-by-step explanation:

EF = ½(BC + AD) => Trapezoid Midsegment theorem

Substitute

5x + 4 = ½((4x + 1) + (7x + 5))

5x + 4 = ½(4x + 1 + 7x + 5)

Multiply both side by 2

2(5x + 4) = 4x + 1 + 7x + 5

10x + 8 = 4x + 1 + 7x + 5

10x + 8 = 11x + 6

Collect like terms

10x - 11x = -8 + 6

-x = -2

Divide both sides by -1

x = 2

Question 1: The sum of two consecutive multiples of 5 is 55. Find these multiples. Question 2: The present age of Sahil's mother is three times the present age of Sahil. After5 years their ages will add to 66 years. Find the present ages. Question 3: The perimeter of a rectangle is 13 cm and its width is 2- cm. Find its length.

Answers

Answer:

1] Two consecutive multiples = 50,55. 2] Sahil , Mother current age = 13,42 3] Length of rectangle = 4.5  

Step-by-step explanation:

1] Let one multiple of 5 be = n. As there are two consecutive multiples, other multiple = n + 1. Given : sum of two consecutive multiples of 5 is 55

So, 5n + 5(n+1) = 55

5n + 5n + 5 = 55 ; 10n + 5 = 55 ; 10n = 50 - 5 = 50 ; n = 50 / 10 ; n = 5

n  {One multiple} = 5 ; Other multiple {n+1} = 5 + 1 = 6

2] Let present age of Sahil be = x. So, present age of Sahil mother = 3x

5 years hence : (x+5) + (3x+5) = 66  {Equation 1}

Solving Eq 1} : x + 5 + 3x + 5 = 66 ; 4x + 10 = 66 ; 4x = 66 - 10 ; 4x = 56

x = 56/4 ; x = 14 {Sahil Current Age}. Mother current age = 3x = 3 x 14 = 42

3] Perimeter of rectangle = 2 (Length + Width). Perimeter = 13 , Width = 2.

So, 13 = 2 (L +2) ; 13 = 2L + 4 ; 2L = 13 - 4 = 9 ; L = 9/2 ; Length = 4.5

John’s Rectangle is _____ units long.

John’s Rectangle is _____ units wide.

The area of John’s rectangle is ____ units^2.

Answers

Answer:

John's rectangle is 4 units long

John's rectangle is [tex]3\frac{1}{2}[/tex] units long

The area of John's rectangle is 14 units^2

Step-by-step explanation:

A rectangle has four sides that comprise of two pairs of equal length sides

The side which is the longest side of a rectangle is known as the length, L, of the rectangle

The side which is the shortest side of a rectangle is known as the width, W of the rectangle

Based on the given measurement, the length of the given rectangle which is the length of longest side of the rectangle, which is the 4 units length side

Therefore;

∴ John's Rectangle is L = 4 units long

the width of the given rectangle which is the length of shortest side of the rectangle, which is the side with lengths 3 units and 1/2 units length side

∴ The length of the shortest side of the rectangle, W = 3 units + 1/2 units = 3 1/2 units

∴ John's rectangle is W = [tex]3\frac{1}{2}[/tex] units wide

The area of John's rectangle, A = L × W

∴ The area of John's rectangle, A = 4 units × [tex]3\frac{1}{2}[/tex] units = 14 units².
