Answer:

19°

Step-by-step explanation:

Set up the equation (triangles add up to 180 degrees)(Right angles are 90 degrees).

39 + 90 + 2x + 13 = 180

142 + 2x = 180

2x = 38

x = 19

a cone with radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown find the volume of the total figure

Darina [25.2K]

Answer: Volume of the cone = 47.12 cubic feet.

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

plug and chug!

h stands for height and r stands for radius.

Work out (8x10^-3) x (2x10^-4)

love history [14]

Answer:

$1.6 \times 10^{-6}$

Step-by-step explanation:

$(8 \times 10^{-3}) \times (2 \times 10^{-4})$

$8 \times 2 \times 10^{-3} \times 10^{-4}$

$16 \times 10^{-3+(-4)}$

$16 \times 10^{-3-4}$

$16 \times 10^{-7}$

$1.6 \times 10^{-6}$

Airline companies raise and lower their ticket prices based on the supply and demand. Due to high numbers of fliers, one company

vovikov84 [41]

The raised price represents 110% of the original price (100% plus the extra 10%)

A percentage is converted into a decimal multiplier by dividing by 100:
$\frac{110}{100} = 1.10$

To clarify the final stage, consider this (where $n$ is the original price):
$n * 1.10 = 192.50$
$1.10n = 192.50$

From here, basic algebraic rules make solving for $n$ easy:
$n = \frac{192.50}{1.10} = 175$

Therefore the original price of a ticket was $175
