Answer: The answer is 40 minutes.

Equation: If m is the total number of minutes it takes him to complete his homework, 30% of m is given by 0.3m. Since 30% was done in 12 minutes, we have 0.3m=12.

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

marissa [1.9K]

Complete question:

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

what is the area of the sector?

Answer:

The area of the sector = $\frac{\pi}{2}$ square units

Step-by-step explanation:

To find the area of the sector of a circle, let's use the formula:

$A = \frac{1}{2} r^2 \theta$

Where, A = area

r = radius = 3

$\theta = \frac{1}{9}\pi$

Substituting values in the formula, we have:

$A = \frac{1}{2}*3^2* \frac{1}{9}\pi$

$A = \frac{1}{2}*9* \frac{1}{9}\pi$

$A = 4.5 * \frac{1}{9}\pi$

$A = \frac{\pi}{2}$

The area of the sector = $\frac{\pi}{2}$ square units

How do I solve 1 1/2c = 6

quester [9]

$1 \frac{1}{2} c = 6 \\ \\ \frac{2 + 1}{2} c = 6 \ / \ convert \ to \ improper \ fraction \\ \\ \frac{3}{2} c = 6 \ / \ simplify \\ \\ \frac{3c}{2} = 6 \ / \ simplify \\ \\ 3c = 6 \times 2 \ / \ multiply \ each \ side \ by \ 2 \\ \\ 3c = 12 \ / \ simplify \\ \\ c = \frac{12}{3} \ / \ divide \ each \ side \ by \ 3 \\ \\ c = 4 \ / \ simplify \\ \\$

So, your answer to this problem is c = 4.
