You are told that the angle the shape makes is 90 hence its a quarter of the circle so you just find the area of the full circle and divide by 4
(6^2*pi)/4
36pi/4
9pi which is around 27 2 Sig fig

Help please I’ll give you 45 points

Answer:

63 square inches

Step-by-step explanation:

You already have the polgygon divided into two rectangles, so we will use them.

The top rectangle has the dimensions of 5 and 9.

The bottom rectangle has the dimensions of 6 and 3.

To find the area of a rectangle:

area = length x width

A = lw

The area of the top rectangle:

A = 5 x 9

A = 45 square inches

The area of the bottom rectangle:

A = 6 x 3

A = 18 square inches

To find the total area, add the two areas together.

45 + 18 = 63 square inches

(6x −9)3−1=((6x−9)3)(0) Solve for X

Tasya [4]

Answer:

Step-by-step explanation:

Remark

Anything multiplied by 0 = 0. So the whole right side is 0.

(6x - 9)*3 - 1 = 0 Add 1 to both sides.

(6x - 9)*3 - 1 + 1 = 0 + 1 Combine

(6x - 9)*3 = 1 Divide both sides by 3

(6x - 9)*3/3 = 1/3 Simplify

(6x - 9) = 1/3 Remove brackets. Add 9 to both sides

6x - 9+9 = 9 1/3 Combine

6x = 9 1/3

6x = 28/3 Divide both sides by 6

6x / 6 = 28/3 // 6 Invert the 6 and multiply.

x = 28/3 * 1/6

x = 28/18

x = 14/9

In the following exercises, solve

Answer:

When the volume of a gas in a container varies inversely with the pressure on the gas and a container of nitrogen has a volume of 29.5 litres with 2000 psi. So, if the tank has a 14.7 psi pressure, then the volume of the tank would be 4013.6 litres.

Step-by-step explanation:

The volume of a gas in a container varies inversely with the pressure on the gas. If a container of nitrogen has a volume of litres with psi, what is the volume if the tank has a psi pressure.

Calculate the volume to the nearest whole number.

Use the given values and calculate the proportionality constant as well as required solution.

Step 1 of 2

Write the inversely proportionality relation between the volume and pressure of a gas in container.

$v \propto \frac{1}{p}$

Where volume is represented by v and pressure is represented by p.

Remove the proportionality and place a constant say k.

$v=\frac{k}{p}$

Substitute the given values of nitrogen that v=29.5 and

p=2000 and calculate the value of k from above equation.

$\begin{aligned}&29.5=\frac{k}{2000} \\&\Rightarrow k=29.5 \times 2000 \\&\Rightarrow k=59000\end{aligned}$

Step 2 of 2

Substitute the value p=14.7 and above calculated k value in the equation

$\begin{aligned}&v=\frac{k}{p} . \\&v=\frac{59000}{14.7} \\&\Rightarrow v=4013.6\end{aligned}$
