Answer:

13, 31

Step-by-step explanation:

Set the width as x.

Length: 2x + 5

Perimeter:

(x) + (2x + 5) + (x) + (2x + 5) = 88

Simplify.

6x + 10 = 88

Solve.

6x = 78

x = 13

Substitute this into the previous equations

Width: 13

Length: 31

Answer:

The length is 31m and the width is 13m.

Step-by-step explanation:

Start by translating the word problem into an equation. 5 more than double the width is written as 2w + 5. Then substitute that into the equation for the perimeter. It should look something like this:

88 = 2(2w +5) + 2w

Then simplify by combining like terms and solve for the width (w).

88 = 6w + 10

78 = 6w

13 = w

Now that we have the width, we can plug it back into the equation we made for the length.

l = 2w + 5

l = 2(13) + 5

l = 26 + 5

l = 31

Answer:

See proof below

Step-by-step explanation:

Find the diagram attached.

From the diagram, sum of angle on the straight  line l is 180degrees that is:

<A' + <B' + <C' = 180° .... 1

Also note that

<A = <A' (corresponding angle) ...2

<B = <B' (corresponding angle) ... 3

<C = <C' (vertically  opposite angle) ...4

Substitute  2, 3 and 4 into 1, we will have:

A+B+C = 180°

This shows that the sum of the interior angles of the triangle A  B and C is 180°

Answer:

Square root of 81 is 9

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

8x - 20 = 44

8x - 20 + 20 = 44 + 20

8x = 64

8x ÷ 8 = 64 ÷ 8

x = 8

Answer: $1.15

Step-by-step explanation:

Data 1 can(c)=0.05

23 cans(c)=x

Only step, multiply 23x0.05=1.15

Reason: Since 1 c=0.05, multiplying is by 23(number of cans) will get us the rate of 23 c

Answer: $1.15(Don't forget the dollar sign)

See Explanation

Step-by-step explanation:

This question is incomplete, as the required scatter plot is not included in the question. I will answer your question with the attached plot.

Solving (a): The equation

Pick any [tex]two[/tex]  [tex]points[/tex]on the [tex]trend[/tex] line

[tex](x_1,y_1) = (30,40)[/tex]

[tex](x_2,y_2) = (80,70)[/tex]

[tex]y = 0.6x + 22[/tex]

Calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

[tex]m = \frac{70 - 40}{80-30}[/tex]

[tex]m = \frac{30}{50}[/tex]

[tex]m = 0.6[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 0.6(x - 30) + 40[/tex]

[tex]y = 0.6x - 18 + 40[/tex]

[tex]y = 0.6x + 22[/tex]

Solving (b): y, when [tex]x = 21[/tex]

[tex]y = 0.6x + 22[/tex]

Substitute [tex]x = 21[/tex]

[tex]y = 0.6 * 21 + 22[/tex]

[tex]y = 12.6 + 22[/tex]

[tex]y = 34.6[/tex]

Solving (c): x when [tex]y=150[/tex]

[tex]y = 0.6x + 22[/tex]

Substitute [tex]y=150[/tex]

[tex]150 = 0.6x + 22[/tex]

Collect like terms

[tex]0.6x = 150 -22[/tex]

[tex]0.6x = 128[/tex]

Solve for x

[tex]x = \frac{128}{0.6}[/tex]

[tex]x = 213.3[/tex]

Answer:

√17 units

Step-by-step explanation:

(6, 8) & (7, 4)

To find the distance between two points, we use the distance formula:

[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]

Plug in the values you know.

[tex]d = \sqrt{(7 -6)^2 + (4 -8)^2 }[/tex]

Evaluate the parentheses.

[tex]d = \sqrt{(1)^2 + (-4)^2 }[/tex]

Evaluate the exponents.

[tex]d = \sqrt{(1) + (16) }[/tex]

Add.

[tex]d = \sqrt{(17)[/tex]

Evaluate the square root.

[tex]d=\sqrt{17}[/tex]

This square root is already fully simplified.

Your answer is √17 units.

Answer:

IT IS FALSE

Step-by-step explanation:

Given:

The figure of a square base pyramid.

To find:

The area of volume of the pyramid.

Solution:

The area of square base is:

[tex]B=(side)^2[/tex]

[tex]B=(16)^2[/tex]

[tex]B=256[/tex]

Area of one triangular side of the pyramid is:

[tex]A_1=\dfrac{1}{2}\times base\times height[/tex]

[tex]A_1=\dfrac{1}{2}\times 16\times 13[/tex]

[tex]A_1=104[/tex]

Now, the total surface area of the pyramid is:

[tex]A=B+4A_1[/tex]

[tex]A=256+4(104)[/tex]

[tex]A=256+416[/tex]

[tex]A=672[/tex]

Therefore, the surface area of the pyramid is 672 square m.

The volume of the pyramid is:

[tex]V=\dfrac{1}{3}Bh[/tex]

Where, B is the base area and h is the vertical height of the pyramid.

Substituting [tex]B=256,\ h=6[/tex], we get

[tex]V=\dfrac{1}{3}(256)(h)[/tex]

[tex]V=(256)(2)[/tex]

[tex]V=512[/tex]

Therefore, the volume of the pyramid is 512 cubic meters.

Hence the correct option is d.

Answer:

Rs.22000

Step-by-step explanation:

Given data

Naveen earns Rs 55,000 per month

He spends 3/5 of his income every month

Let us find the amount he spends

=3/5*55,000

=165000/5

=Rs.33000

Hence the savings is

= 55,000-33000

=Rs.22000

Answer:

11x11 inches

Step-by-step explanation:

You are missing the first part of the problem, which is the following:

"Miriam reduced a square photo by cutting 3 inches away from the length and the width so it will fit in her photo album. The area of the reduced photo is 64 square inches. In the equation (x – 3)2 = 64, x represents the side measure of the original photo. What were the dimensions of the original photo?"

With this in mind, we just need to solve the equation and determine the value of x. The equation is:

(x - 3)² = 64

Solving this, we have:

x - 3 = √64

x - 3 = 8

x = 8 + 3

Therefore, we can conclude that the original dimensions of the photo are 11x11 inches.
