Answer:

cos R = .38

Step-by-step explanation:

First you need to find the length of the hypotenuse.

Use a squared + b squared = c squared

100 + 576 = c squared

square root of 676 is 26

CosR is adjacent over hypotenuse.

Adjacent is 10

Hypotenuse is 26

10/26 = .38

The floor of Cara's living room is 10 feet by 14 feet. What is the area, in square feet, of the largest circular rug that can fi

Rus_ich [418]

Answer:

$78.5\ ft^{2}$

Step-by-step explanation:

we know that

If the floor of Cara's living room is 10 feet by 14 feet

then

the diameter of the larger circular rug that can fit in Cara's living room is equal to 10 feet

Find the area of the circular rug

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=10/2=5\ ft$ ----> the radius is half the diameter

$\pi=3.14$

substitute the values

$A=(3.14)(5)^{2}=78.5\ ft^{2}$

Carbon dioxide comprises approximately what percentage of the atmosphere

In-s [12.5K]

The Carbon Dioxide in the atmosphere is only very small relative to other gases. Typically, it only consists about 0.038 percent or 0.04 percent of the gases in the atmosphere.

Even though it is only small, CO2 is very important since it is one of the greenhouse gases which ensures that the Earth stays warm.
