Answer:

B. 3.72 x [tex]10^{7}[/tex]

Step-by-step explanation:

The distance between the sun and Mercury is approximately 36,000,000 miles.

Move the decimal point 7 positions to the left so that there is only one digit to the left of it.

Multiply that number by 10 raised to the power of 7

7 is the number of positions that the decimal point was moved.

I do not know this subject too well but hopefully this helps.

Answer:

K = -2J + 24

Step-by-step explanation:

Find two point of the line

(12,0) ; (10,4)

Use this equation:

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y-0)/(4-0) = (x-12)/(10-12)

y/4 = (x-12)/(-2)

y/4 = (-x+12)/2

y = -2x + 24

4x + 3(2x - 4) = x

Step 2: Solve for x

Answer:

x = 1.33

Step-by-step explanation:

4x + 3(2x-4) = x

-4x                 -4x

3(2x-4) = -3x

Distribute 3 to (2x-4)

6x - 12 = -3x

B.) 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5

Step-by-step explanation:

From the box plot, we can obtain the 5 - Numbe summary and compare with the values in the options given :

Kindly note that each tick mark on the box plot is seperated by a unit of 0.25

Minimum = 0 (starting point of left whisker)

Lower quartile = 0.25 (start point of box)

Median = 0.5 (point in between the box)

Upper quartile = 1.25 (end point of the box)

Maximum = 2.5 (end point of right whisker)

In ascending order we have ;

0, 0.25, 0.5, 1.25, 2.5

The data which best matches the plot is 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5

Answer:

$36

Step-by-step explanation:

1. Determine the surface area of the  largest jaw breaker

Surface area of a sphere = 4πr²

4 x 3.14 x 2² = 50.24in²

2. Determine the surface area of the new jaw breaker

4 x 3.14 x 6² = 452.16 in²

3. Determine the cost per area

4/ 50.24

4. Determine the price for the new jaw breaker

4/ 50.24 x 452.16 = $36

Answer:

40/41

Step-by-step explanation:

From the given diagram;

BA is the hypotenuse = 41

AC is the opposite = 9

CB is the adjacent = 40

Cos<B = adjaccent/hyp

Cos<B = CB/BA

Cos<B = 40/41

Hence the required ratio is 40/41

Answer:

[tex]456\ m^2[/tex]

Step-by-step explanation:

In order to find the surface area of a 3-dimensional figure, one must find the 2-dimensional area of all of its faces, then add up the values to find the surface area of the entire figure. The given prism is drawn out in the form of a net, thus, it is rather easy to find the area of each face, and add up the area to find the surface area.

The lateral surface area refers to the surface area of a figure, not including the base of the figure. In this case, the base is the largest rectangle: the one with the dimensions of the following length  

[tex](12)*(18)[/tex]

Use the following formulas to find the surface area of each face:

Rectangle: [tex](length)(width)[/tex]

[tex](10)(18)=(180)[/tex]

[tex](10)(18)=(180)[/tex]

Triangle:[tex]\frac{(base)(height)}{2}[/tex]

[tex]\frac{(12)(8)}{2}=48[/tex]

[tex]\frac{(12)(8)}{2}=48[/tex]

Add up all of these values to find the total surface area:

[tex](180)+(180)+(48)+(48)=456[/tex]

Answer:

A - 6 units from the y axis. B - 5 units form the x axis. C - 8 units from T to V.

Step-by-step explanation:

So lets go over each question.

A asks for how many units point W is from the y axis. The y axis is the vertical line that goes up and down in the middle of the graph. This line is at x=0.

So we can think of the units between W and the y axis as the distance between W's x coordinates and 0.

In this case, we can see W's x coordinate is at 6.

So this means that W is 6 units from the y axis.

Next we have the distance between the x axis and point U.

The x axis is the line that goes left to right, and is at y=0.

We need to look at the y coordinate of U to find the difference between y=0 and U.

We can see that U is at y=5 on the graph.

So U is 5 units from the x axis.

The last question is the distance between point V and T.

We can see that the x coordinate for both points is x=2.

However, their y coordinates are different.

To find the difference, subtract the y coordinate of one point from the other.

In this case, the y coordinate of V is 5. The y coordinate of T is -3.

So lets see:

v-t=difference of y.

Plug in the values:

5--3

And since the negative sign and the minus sign cancel out:

5+3

=

8

So the difference in y is 8!

Hope this helps!

About $48.39

Step-by-step explanation:

Sales tax only applies to the bill, not the tip.

Calculate the sales tax:

38.96 × 8%

38.96 × 0.08

3.1168

Round to the nearest cent:

3.12

Add the sales tax to the bill:

38.96 + 3.12

42.08

Calculate the tip based "on the total amount of the bill:"

42.08 × 15%

42.08 × 0.15

6.312

Round to the nearest cent:

6.31

Add the tip to the rest of the bill:

42.08 + 6.31

48.39

Answer:

Amount of interest received by Phoebe = $300

Step-by-step explanation:

Given:

Amount Phoebe invested = $5,800

Amount Phoebe received after one year = $6,100

Find:

Amount of interest received by Phoebe

Computation:

Amount of interest received by Phoebe = Amount Phoebe received after one year - Amount Phoebe invested

Amount of interest received by Phoebe = 6,100 - 5,800

Amount of interest received by Phoebe = $300

Answer:

foreign stamps = 299

US stamps = 353

Step-by-step explanation:

Let number of foreign stamps be x.

Given she has 54 more U.S stamps than foreign , US stamps = x +54

Total stamps = US + Foreign

652 = x + 54 + x

652 - 54 = 2x

598 = 2x

x = 299

Step-by-step explanation:

Hi,

I cannot see the options but for vertical compression you need to have values of a that are 0<a<1, then the graph will be compressed.

For example, if we have g(x)= 1/2 x^2 will be compressed by factor of 1/2.

Answer:

The 4th one is the least so you would put that as the first one, then the 2nd one, then the 1st one, then the 3rd one.

Step-by-step explanation:

The fourth one is first because 10 to the power of 0 is 0 times 10 to the power of 1 is still 0 minus 1 to the power of 10 is 1 so 0 minus 1 is -1. The second one is second because 10 to the power of 0 times 10 to the power of 1 is 0, times 1 to the power of 10 is still 0. The first one is third in line because 10 to the power of 0 plus 10 to the power of 1 is 10 times 1 to the power of 10 is 10. The third one is last because its the greatist, 10 to the power of 0 plus 10 to the power of 1 is 10 plus 1 to the power of 10 is 11.
