height?
User pie= 3.14 and round your answer to the nearest hundredth.
hz
millimeters
Answer:
10
Step-by-step explanation:
Volume of a cone is:
V = 1/3pi•r^2•h
Fill in the given information.
847.8
= 1/3(3.14)9^2•h
847.8 = 84.78h
divide by 84.78

On a coordinate plane, point F is located at points 3, 7 and point G is located at points 9,7. whats the distance in units between point F and point G? Enter the answer in the box.
Answer:
6 units
Step-by-step explanation:
since the y- coordinates of both points are 7 then the horizontal distance between the points is the absolute value of the difference in the x- coordinates , that is
d = | 9 - 3 | = | 6 | = 6 units , or
d = | 3 - 9 | = | - 6 | = 6 units
Find the slope of the line passing through (-2 , 1) and (1,1)
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)

Does anybody know this?Two complementary angles are in the ratio of 4:6 find the measure of the smallest angle and the value of x.
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.
(-9m+9) + (8m+8) simplify
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....

Answer:
9000 ft
Step-by-step explanation:
Given: A airplane is ascending at a constant rate of 15 feet per second,
What we need to know: The change in altitude during 10 minutes of flight,
60 seconds = 1 minute
60 × 10
= 600 seconds
600 × 15
= 9000 ft
Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.
A center has a center at X(4, -3) and a point on the circle is W(8, 0). What is the location of Y on the diameter WY?

We have a circle with center K with an arc HJ with a measure of 40°. What is the measure of angle HIJ?
40°
60°
80°
20°
The measure of angle HIJ is 20°. The correct option is the last option 20°
Circle GeometryFrom 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°

Jones planted s flowers. He planted fewer flowers than Kerry. Kerry
planted 50 flowers. Write the expression that shows how many flowers Jones
planted.
Answer:
s < 50
Step-by-step explanation:
This is an inequality that can be used to express the amount of flowers planted. If Jones planted s flowers, Kerry planted 50, and Jones planted less flowers than Kerry, s must be less than 50.

year, what happened to the purchasing power of her savings?
•
It increased
It decreased
It stayed the same
It matched inflation
The purchasing power of Sandra's savings according to the description above has decreased.
What happens to the purchasing power of Sandra's savings?It follows from the task content that Sandra's savings attracted an annual interest rate of 1% while the inflation is 2% per annum. On this note, it follows that Sandra's savings purchasing power has reduced as the prices of commodities have gone up and the interest rate is unable to match it.

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