Step-by-step explanation:

Answer:

Length of one side is 8 units

Step-by-step explanation:

Given

The centre of this square is positioned at the origin as visible form the four co-ordinates

All the four co-ordinates are such that they are 4 units along the x-axis and 4 units along the y-axis.

Let us take the following two co-ordinates - (4,4),(4,−4). The X value for these two co-ordinate points is 4 and the Y values are such that one point has y = 4 and the other has y = -4 i.e 8 units in between.  

Thus, length of one side is 8 units.  

Answer:

The tax on the car equals $480, based on a 6% rate.

Step-by-step explanation:

Giving the following information:

Tax rate (t)= 6% = 0.06

Purchase price= $8,000

To calculate the tax (T), we need to use the following formula:

Tax= tax rate*purchase price

Tax= 0.06*8,000

Tax= $480

The tax on the car equals $480, based on a 6% rate.

Answer:

The width of the frame is 2 inches

Step-by-step explanation:

The given dimensions of the picture = 7 inches by 7 inches

The area of the picture, A₁ = 7 in. × 7 in. = 49 in.²

The area of the given picture and the frame, A₂ = 81 square inches

Let 'w' represent the width of the frame and whereby the picture is a square, we have;

The area of the picture with the frame, A₂ = 81 in.² = (7 + w) × (7 + w)

A₂ = 81 = (7 + w) × (7 + w) = 49 + 14·w + w²

49 + 14·w + w² - 81 = 0

w² + 14·w - 32 = 0

(x + 16)·(x - 2) = 0

∴ x = -16 or x = 2

Given that 'x' is a natural number, we have;

The width of the frame, x = 2 inches.

Answer:

The solutions to the equation are [tex]x = \frac{1}{5}[/tex] and [tex]x = -4[/tex]

Step-by-step explanation:

The factors of the quadratic function g(x) are (5x – 1) and (x + 4).

This means that:

[tex]g(x) = 0[/tex]

[tex](5x - 1)(x + 4) = 0[/tex]

So

[tex]5x - 1 = 0[/tex]

[tex]5x = 1[/tex]

[tex]x = \frac{1}{5}[/tex]

And

[tex]x + 4 = 0[/tex]

[tex]x = -4[/tex]

The solutions to the equation are [tex]x = \frac{1}{5}[/tex] and [tex]x = -4[/tex]

Answer:

x = 25.3

x = 25.3

Answer:

The area of the roof is 3.80 m².

Step-by-step explanation:

The lateral surface area of an octagonal pyramid is given by:

[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}})[/tex]   (1)

Where:

s: is the length of the base edge = 0.5 m

h: is the height                                                                                                      

We can find the height from the slant height (S = 1.9 m):

[tex] S = \sqrt{h^{2} + 1.457s^{2}} [/tex]   (2)

By solving equation (2) for "h" we have:

[tex] h = \sqrt{S^{2} - 1.457s^{2}} = \sqrt{(1.9)^{2} - 1.457(0.5)^{2}} = 1.80 m [/tex]

Now, we can calculate the area of the roof (equation 1):

[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}}) = 2*0.5(\sqrt{4(1.80)^{2} + 5.828(0.5)^{2}}) = 3.80 m^{2}[/tex]

Therefore, the area of the roof is 3.80 m².

Answer:

The difference is 6.74 * 10^-3 centimeters

Step-by-step explanation:

Firstly, we need to write the numbers as they would occur normally

we have this as;

7.65 * 10^-3 = 0.00765

9.1 * 10^-4 = 0.00091

So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number

we have this as;

0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters

Answer:

133 windows in 7 hours

Step-by-step explanation:

38 divided by 2 and you get 19

19 x 7 = 133

Answer:

133 windows

Step-by-step explanation:

First, you would want to find how many windows he can clean in 1 hour.

You know that 38 windows = 2 hours.

To do this, divide both sides by 2 (to get 1 hour). You will get 19 windows = 1 hour.

Now to find 7 hours, multiply both sides of 19 windows = 1 hour by 7 (to get 7 hours). You will get 133 windows cleaned in 7 hours.

Answer:

y = 52

x = 5

Step-by-step explanation:

14 x + y = 122

y = 52

x = 5

Answer:

x = 25

Step-by-step explanation:

The angles in a triangle must add up to 180 degrees, so:

180 - (53 + 27) = 100

100 ÷ 4 = 25

Step-by-step explanation:

[tex] \sin(20 \degree) = \frac{3}{AB} \\ AB = \frac{3}{ \sin(20 \degree) } \\ AB = \frac{3}{0.342} \\ AB = 8.77[/tex]

Answer:

Randomized block design

Step-by-step explanation:

In the scenario described above, the subjects which are the different car types are grouped into fixed units of 4 called blocks with each unit then assigned randomly to a particular treatment condition, which are the 4 different types of tire. In the end, the mean mileage for each block is taken and compared to that of the other blocks. This type of research design improves the reliability of the result obtained as it also eliminates the occurrence of systematic error in the course of our experiment.

Answer:

Use this to get the area of any circle A = π r²

Step-by-step explanation:

I guess the upper circle has a radio of 10.5 m, then you multiply it by itself and you get that 10.5^2=110.25, and to that you add "π", and the area would be this "110.25π m."

And the other one is 7^2π=49π

Answer:

The southern lighthouse is 3.4 miles closer than the northern lighthouse

Step-by-step explanation:

From the figure we see that we need to find the distances AK and BK.

The measure of the third angle K is = 180- 25-35= 120 degrees

Using the sine ratios we can find the two distances

From the figure

The northern distance is given by

20/ sin 120 = kA/ sine 35

KA= 20 sine 35/ sine 120

KA= 13.25 miles

The southern distance is given by

20 /sine 120= KB / sine 25

20 sine 25/ sine 120 = KB

KB= 9.759=9.76 miles

Difference between the two miles =

13.25 miles - 9.76 miles = 3.49 miles

The southern lighthouse is 3.4 miles closer than the northern lighthouse
