Area of the base is πr² where r is the radius. The volume of a cone is ⅓ πr²h where h is the height.
So the volume is ⅓ π×9×10=30 π=94.25 cu in approximately.

What is the result of multiplying the second equation by 2 and adding to the first equation?

vladimir1956 [14]

Answer:

5x + y = 8

Step-by-step explanation:

Given the equations:

x+3y=10 ____ (1)

2x−y=−1 ____ (2)

Multiply (2) by 2

2(2x - y = - 1) = 4x - 2y = - 2

4x - 2y = - 2 - - - (3)

Add (1) and (3)

4x - 2y = - 2

x + 3y = 10

___________

5x + y = 8

Use the properties of logarithms to expand the following expression as much as possible. simplify any numerical expressions that

FinnZ [79.3K]

$\bf log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)
\\ \quad \\\\
% Logarithm of rationals
log_{{ a}}\left( \frac{x}{y}\right)\implies log_{{ a}}(x)-log_{{ a}}(y)
\\ \quad \\\\
% Logarithm of exponentials
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\\\\
-----------------------------\\\\
ln\left( \cfrac{6x^9}{y^5} \right)\implies ln(6x^9)-ln(y^5)\implies ln(6)+ln(x^9)-ln(y^5)
\\\\\\
ln(6)+9ln(x)-5ln(y)$

What are 3 complex fractions that simplify to 1/4??

Aleksandr-060686 [28]

Give 3 complex fractions that simplify to ¼
Complex fractions are bigger fractions that can be simplified into smaller fractions. => First is 15 / 60
15/60 = 1 /4
=> second is 50/200
50/200 = 1 / 4
=> Third is 43/172
43/172 = 1 / 4

There are many possible answer. There are infinite complex fractions that can be simplified to 1 /4. I only gave 3 examples to show how simplified fraction works.

Here's the question

zheka24 [161]

Answer:

Step-by-step explanation:

perimeter (p) = 8 + 17 + 15 = 40

semi-perimeter (s) = p/2 = 20

Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.

Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
