A slope of something that is parallel is the same slope. It's 2 (2/1) and it can be anything for the y intercept but 5

Step-by-step explanation:

$\begin{array}{ccc}1&-&d\\2&-&c\\3&-&a\\4&-&b\\5&-&f\\6&-&e\end{array}$

Value 1:

r = 5ft, h = 10ft. Substitute:

$SA=2\pi(5)(10)+2\pi(5^2)=100\pi+50\pi=150\pi\ ft^2$

Value 2:

r = 2in, h = 4in. Substitute:

$V=\dfrac{1}{3}\pi(2^2)(4)=\dfrac{1}{3}\pi(4)(4)=\dfrac{16\pi}{3}\\\\\pi\approzx3.14\to V\approx\dfrac{(16)(3.14)}{3}\approx16.75\ in^3$

Value 3:

r = 6m. Substitute:

$V=\dfrac{4}{3}\pi(6^3)=\dfrac{4}{3}\pi(216)=4\pi(72)=288\pi\ m^3\\\\\pi\approx3.14\to V\approx288(3.14)=904.32\ m^3$

What is 12% of 30 HELP I DON'T KNOW THIS QUESTION AT ALL

luda_lava [24]

Convert percent to decimal by moving the percent sign two places to the left.

12% => 0.12

'Of' in math means multiply: 0.12 * 30 = 3.6

3.6 is the answer.

Find a. Round to the nearest tenth.

Kazeer [188]

Answer:

21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

We need to know the angle A. Its value is ...

A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.
