Volume of a Cone: V = 1/3πr²hStep-by-step explanation:
Step 1: Define variables
r = 10 in
h = 8 in
Step 2: Find Volume
Substitute: V = 1/3π(10 in)²(8 in)Evaluate: V = 1/3π(100 in²)(8 in)Multiply: V = 1/3π(800 in³)Multiply: V = 1/3(2513.27 in³)Multiply: V = 837.758 in³And we have our final answer!

Answers
Answer:
First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))
So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).
So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.
Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3
In short, 3(2^0) = 3

After raining for 3/4 of an hour, a rain gauge is 2/5 filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled?
To help answer this question, Diego wrote the division equation 3/4 ÷ 2/5 = ?. Explain why this equation does not represent the situation.
Answers
Number of minutes in 3/4 of an hour is :
n = 3/4 × 60 = 45 minutes.
Now, If it continues to rain at that rate for 15 more minutes :
So, time taken = 45 + 15 min = 1 hour.
Let, rain gauge is filled x fraction in 1 hour.
So,
[tex]\dfrac{3}{4}x = \dfrac{2}{5}\times 1\\\\x = \dfrac{8}{15}[/tex]
Hence, this is the required solution.

Write an equation of the line that is perpendicular to 2x +4y = 6 and passes through the point (6,4)
Answers
Answer:
B
Step-by-step explanation:
let equation be y = mx + b.
2x + 4y = 6
1/2x + y = 3/2
y = -1/2x + 3/2
since perpendicular, their gradients produced equals neg 1.
so,
m = -1/(-1/2) = 2
sub (6, 4):
4 = 2(6) + b
b = -8
therefore, eqn is y = 2x - 8

Step-by-step explanation:
Since each grid square is 1/4 unit. the coordinates in terms of grid squares are ...
A(0.50, -1.25) ⇒ (0.50/.25, -1.25/.25) = (2, -5) . . . grid squares
Point A is located 2 squares right and 5 squares down on the grid. This matches choice D.

—————. = 168
n
180( n - 2) = 168n
180n - 360 = 168n
12n = 360

Answers
Answer: ∠1 = 77; ∠3 = 41; ∠5 = 41; ∠6 = 92; ∠9 = 103; ∠12 = 47; ∠14 = 103; ∠17 = 41
because of 2 parallel lines
=> ∠1 = ∠10 = 77°
∠7 = ∠12 = 47°
∠16 = ∠7 + ∠6 = 139° ⇒ ∠6 = 139° - ∠7 = 92°
have: ∠7 + ∠6 + ∠5 = 180° ⇒ ∠5 = 180° - (∠7 + ∠6) = 180° - 139° = 41°
∠10 + ∠14 = 180° ⇔ ∠14 = 180° - ∠10 = 103°
∠14 = ∠9 = 103°
∠3 = ∠5 = ∠17 = 41°

what is the value of angle s
Answers
Answer:
54
Step-by-step explanation:
As we know s+19+(180-73)=180
so s+19=73
s=54
Answer: 54°
Explanation:
73° is a complementary angle so the angle next to it has to add up to 180 so it’s 107
All 3 angles have to add up to 180 so 107+19=126
180-126= 54
