Answer:
The volume of this figure is approximately 418.88 centimeters squared!
Step-by-step explanation:
The volume for a right circular cone is V = (π)(r^2)(h/3)
Substituting known values is as follows:
V = (π)(r^2)(h/3)
V = (π)(4^2)(25/3)
V = (π)(16)(25/3)
V ≈ 418.88 cm^3
What is being done to the variable in the equation = -40?
It's being multiplied by -40.
It's being multiplied by -5.
It's being divided by -40.
It's being divided by 5.
Answer:
It's being divided by 5.
Step-by-step explanation:
In this question, the variable being used in the equation is being divided by 5. This is represented by the / symbol in the equation which is the symbol for division. If we multiply both sides by 5 we can isolate the variable M and get its value like so...
M/5 = -40 ... multiply both sides by 5
M = -200
Therefore in this scenario, the value of M would be -200

z²÷ayWhat is the area of the figure, in m2 , shown below?.
Answer:
The area of this figure is 22 meters squared
Step-by-step explanation:
Two shapes exist on this figure: a rectangle and a triangle. We must first find the area of the rectangle and add that area to the area of the triangle. So first, let's solve the rectangle.
As the area of a rectangle is length multiplied by width, we have 8 * 1 = area, or 8 meters squared. Now we save the value of 8 to add to the area of the triangle. So let's now figure out the area of the triangle.
As the area of a triangle is A = (HB)/(2), or that triangles height multiplied by its base, and dividing that whole number by 2, we can substitute numbers into this equation. This means we take 3.5, the height of the triangle, and multiply that number by 8, the base of the triangle, to get a value of 28. We then divide 28 by 2 to satisfy the equation A = (HB)/(2), and we get the value of 14.
Because of this, we add 8, the area of the rectangle, and 14, the value of the triangle to get a total value of 22. Now let's not forget to add meters squared as the unit of measurement as stated in the question.
This means that the total area of this figure is 22 meters squared.

A woman bought 210 oranges for 650 she sold all of them at 3 for 20 how much profit did
she make
Answer:
750
Step-by-step explanation:
total cost = 650
total selling = 210/3 x 20 = 70 x 20 = 1400
total profit = 1400 - 650 = 750

What is the Slope-Intercept Form of 16x + 4y = 44
Answer:
Y=-4x+11
Step-by-step explanation:
So first you gotta realize that slope intercept from is
y=mx+b
So you have the equation of
16x+4y=44 as the initial response
Now you just have to isolate it into the from of y=mx+b
SO first subtract 16x on both sides to isolate the 4y since its the initial response as y=mx+b
Then when that is done you should have the answer of
4y= 44-16x
Now You have to isolate the “y”.
By dividing 4 on both sides to get the new equation which will be
y= 11-4x
You can leave it like that or just move around the (x) to make it more plausible as the answer of y=mx+b
y= -4x+11
However you would put it, that is the answer
y= -4x+11
And
y= 11-4x

Work out the surface area of this solid prism.
9m
10m
6m
8m
Given:
Consider the below figure attached with this question.
To find:
The surface area of this solid prism.
Solution:
The surface area of this solid prism is
[tex]A=P\times h+2B[/tex]
Where, P is the perimeter of the base, B is the area of the base and h is the height of the prism.
Perimeter of the base is:
[tex]P=6+8+10[/tex]
[tex]P=24[/tex]
Area of the base is:
[tex]B=\dfrac{1}{2}\times base\times height[/tex]
[tex]B=\dfrac{1}{2}\times 8\times 6[/tex]
[tex]B=24[/tex]
Putting [tex]P=24[/tex] and [tex]B=24[/tex] in the formula for area, we get
[tex]A=(24)\times 9+2(24)[/tex]
[tex]A=216+48[/tex]
[tex]A=264[/tex]
Therefore, the surface area of the given prism is 264 m².

Find the missing term(s) of the geometric sequence: 39, a2 , 975, ... Hint: r can be positive or negative.
9514 1404 393
Answer:
±195
Step-by-step explanation:
For some common ratio r, your missing term satisfies ...
39r = a2
a2·r = 975
So, ...
975 = 39r^2
25 = r^2
r = ±√25 = ±5
The missing term a2 = 39r could be either of 195 or -195.
