Answer:
(1/3)πr2h.
Step-by-step explanation:
Volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
Base surface area of a cone (a circle):
B = πr2
Total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

what do I do for this
Answer:
The answer is C
Step-by-step explanation:
OK, so you know the equation y = mx + b?
To find the slope, divide rise/run
Since the line is going down, that means the slope is negative.
See which y has x = 0
In this case it’s -1
so it has to be C

Trent borrowed $250 with a 2.5% simple interest rate he pays back the money in one year what was the total amount that he repaid
Answer:
$256.25
Step-by-step explanation:
The amount Trent pays back is the principal ($250) plus the interest after one year ([tex]$250\times 0.025 = 6.25[/tex]). We add the total to obtain $256.25.

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.
Imagine this happening:
1$
Uses 1/4
So... Let's look at what I've given you.
2/4=0.5
3/4=0.75
Well, let's stretch some things a liiiiitle bit.
Bob has a dollar bill blah blah...
We get to 1/4.
Le's make that 2/4.
2/4 is 0.5
So... By stretching the truth
We can infer that
If we put 1/4 back
(Oh no now the word problem creators are mad at me ;) lol)
Anyways, we can infer that by putting 1/4 back
That since 3/4 is 0.75
Then what's connected to 0.5 and 0.75?
The answer, my friend,
Is 0.25

Step-by-step explanation:
I NEED THE ANSWERS WITH AN EXPLANATION PLS!!
1. The perimeter = 120 m; length = 45 m ; breadth = ____
2. Perimeter of a rectangle = 250 m; breadth = 50m; length = _____
1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5
2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

An irregular hexagon has angles that measure the following. Angle 1: 2x + 15 Angle 2: 9x - 3 Angle 3: 77 Angle 4: 8x + 8 Angle 5: 13x Angle 6: x - 4 What is the value of x?
Answer: 19
Step-by-step explanation:
1) You combine like terms with all the angles
Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93
2) You set up an equation using the formula for the sum of the interior angles
Ex. 33x + 93 = 180(n - 2)
3) Since a hexagon has 6 sides, n is 6
Ex. 33x + 93 = 180(6 - 2)
4) Solve like a regular equation
Ex. 33x + 93 = 180(6 - 2)
33x + 93 = 720
- 93 = - 93
33x = 627
- Divide 627 by 33
x = 19

Answer:
y = -4/3x - 1
Step-by-step explanation:
solve
4(2x - 3) = 6x + 2
Answer:
x =7
Step-by-step explanation:
Let's solve your equation step-by-step.
4 ( 2x − 3 ) = 6x + 2
Step 1: Simplify both sides of the equation.
4 ( 2x − 3 ) = 6x + 2
( 4 ) ( 2x ) + ( 4 ) ( −3 ) = 6x + 2 ( Distribute )
8x + −12 = 6x + 2
8x − 12 = 6x + 2
Step 2: Subtract 6x from both sides.
8x − 12 − 6x = 6x + 2 − 6x
2x − 12 = 2
Step 3: Add 12 to both sides.
2x − 12 + 12 = 2 + 12
2x = 14
Step 4: Divide both sides by 2.
2x / 2 = 14 / 2
x = 7

Suppose a is an irrational number
and is a rational number. Can
their sum be rational? Explain your
answer.
Answer:
The sum of a rational number and an irrational number is irrational
Step-by-step explanation:
By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal.
Example:
[tex]3+\sqrt{5} = 3+2.236067977...=5.236067977....[/tex]

1. Find the sum of the measures of the interior angles of a convex 11-gon.
Answer:
The measure of the sum of interior angles of a 11-gon is [tex]1620^{o}[/tex].
Each interior angle is approximately [tex]147.273^{o}[/tex].
Step-by-step explanation:
A convex polygon has the measure of each interior angles to be less than [tex]180^{o}[/tex].
But,
sum of interior angles of polygon = (n - 2) x [tex]180^{o}[/tex]
where n is the number of sides of the polygon.
For a convex 11-gon, we have;
sum of angles of a 11-gon = (11 - 2) x [tex]180^{o}[/tex]
= 9 x [tex]180^{o}[/tex]
= [tex]1620^{o}[/tex]
Sum of angles of a 11-gon = [tex]1620^{o}[/tex]
To check: convex polygons' interior angles are less than [tex]180^{o}[/tex].
so that,
each interior angle of 11-gon = [tex]\frac{1620}{11}[/tex]
= [tex]147.273^{o}[/tex]
