Answers

-10 + -v - 2 + -9

First, simplify. / Your problem should look like: -10 - v - 2 - 9
Second, simplify/subtract. / Your problem should look like: -v - 21

Answer: -v - 21

-10+-v-2+-9 = -10-v-2-9 = -v -21 =\boxed {-1 (v+21)}

The combined area of the 3 windowpanes and frame shown below is 924 in.2. The frame is of uniform width. What is the side length, x, of each square windowpane?

A. 10 in. B. 20 in. C. 15 in. D. 25 in.

Answers

Answer:

Option A. x=10\ in

Step-by-step explanation:

we know that

The combined area of the 3 windowpanes and frame is equal to

(3x+12)(x+12)=924\n \n3x^(2)+36x+ 12x+144=924\n \n 3x^(2)+48x-780=0

using a graphing tool to solve the quadratic equation

The solution is x=10\ in

If the diameter of a circle is 6 inches, how long is the arc subtended by an angle measuring 70°?

Answers

Answer:

7π/6 inches ( = 3.67 inches)

Step-by-step explanation:

given diameter = 6 inches, radius = 6/2 = 3 inches

circumference (i.e full 360°) = 2πr = 2π (3) = 6π inches

fraction of full circle represented by 70° = (70/360)

arc length subtended by 70° = (70/360) x 6π = 7π/6 inches ( = 3.67 inches)
