Answer:

7

Step-by-step explanation:

you add all the numbers together and get 70, and then you divide that answer (70) by the amount of numbers that are listed (10), and you get the answer 7. Also if this is wrong its because i'm in class and about to leave so i'm in a rush.

Answer:

M+16m

Step-by-step explanation:

-9m+9 cancel eachother out because it is a negative and a postive value, so you would just put the variable. For 8m+8 it would be 16m because the sre both positive so you would add them like normal

Step-by-step explanation:

[tex] = ( - 9m + 9) + (8m + 8)[/tex]

[tex] = - 9m + 9 + 8m + 8[/tex]

[tex] = - 9m + 8m + 9 + 8[/tex]

= m + 17

hence m + 17 is the answer....

The measure of angle HIJ is 20°. The correct option is the last option 20°

From the question, we are to determine the measure of angle HIJ

From one of the Circle theorems, we have that

The angle at the center of a circle is twice the angle at any part of the circumference

From the information,

The measure of arc HJ is 40°. That is, the angle at the center is 40°.

Then, using the above theorem,

Measure of angle HIJ = 40° / 2

Measure of angle HIJ = 20°

Hence, the measure of angle HIJ is 20°. The correct option is the last option 20°

Answer: (0, -6)

Step-by-step explanation:

The center is the midpoint of the diameter, meaning that the coordinates of Y must be (0, -6).

[tex]\text{Given that,}~ (x_1 ,y_1) = (0,-4)~ \text{and}~ (x_2 ,y _2) = (30,-9)\\\\\text{Slope,}~ m = \dfrac{y_2-y_1}{x_2 -x_1}\\\\\\~~~~~~~~~~~~~=\dfrac{-9-(-4)}{30-0}\\\\\\~~~~~~~~~~~~~=\dfrac{-9+4}{30}\\\\\\~~~~~~~~~~~~~=\dfrac{-5}{30}\\\\\\~~~~~~~~~~~~~=-\dfrac 16[/tex]

The slope of the line that passes through the points (0, -4) and (30, -9) is -1/6

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=(y₂-y₁)/(x₂-x₁)

x₁=0, y₁=-4, x₂=30, y₂=-9

Substitute in slope formula

m=(-9-(-4))/(30-0)

m=-9+4/30

m=-5/30

m=-1/6

Hence the slope of the line that passes through the points (0, -4) and (30, -9) is -1/6

Answer:

36

Step-by-step explanation:

A ratio 4:6 means the one quantity is 4/10 of the full thing:

While the other quantity is 6/10 of the full thing

So the smaller angle will be 4/10 of the the complementary angle.

Complementary angle is 90.

So 4/10 of 90 is 36.

Using the surface area of the sphere, it is found that the radius of the bearing that Helen needs to buy is of 6 millimeters.

The surface area of a sphere of radius r is given by:

[tex]S_A = 4\pi r^2[/tex]

In this problem, we have that:

[tex]S_A = 452.16[/tex]

Hence:

[tex]4\pi r^2 = 452.16[/tex]

[tex]r = \sqrt{\frac{452.16}{4\pi}}[/tex]

r = 6.

Answer:

The slope of the line is: M = 0

Step-by-step explanation:

Using the "Slope from 2 points" formula which is \/

M = (y2 - y1) / (x2 - x1)

We just need to input the numbers to find the slope!
M = ( 1 - 1 ) / (1 - - 2 )

Now solve within the parentheses:

M = ( 0 ) / ( 3 )

Which is basically just 0.

I hope the formula: M = ( y2 - y1) / (x2 - x1)
