Answer:

m =-6

Step-by-step explanation:

To solve for the unknown variable, m, we have to get m by itself. Perform the opposite of what is being done to the equation.

-8m-9=39

9 is being subtracted from-8m, so add 9 to both sides. Addition is the opposite of subtraction.

-8m-9+9=39+9

-8m=39+9

-8m=48

-8 and m are being multiplied. Divide both sides by -8, because division is the opposite of multiplication

-8m/-8=48/-8

m=48/-8

m= -6

A car's rear windshield wiper rotates 130°. The total length of the wiper mechanism is 25 inches and the length of the wiper bla
Delicious77 [7]

The area wiped by the viper blade is approximately 486.7 square inches.

The area wiped by the wiper blade (A), in square inches, is equal to the area of the circular section described below:

A = \frac{\theta\cdot \pi}{360}\cdot (R^{2}-r^{2}) (1)

Where:

  • \theta - Angle, in sexagesimal degrees.
  • r - Inner radius, in inches.
  • R - Outer radius, in inches.

If we know that \theta = 130^{\circ}, R = 25\,in and r = 14\,in, then the area wiped by the wiper blade is:

A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}]

A \approx 486.7\,in^{2}

The area wiped by the viper blade is approximately 486.7 square inches.
