Geometry help needed! Jennifer decided to replace the rectangular rug in her living room. The dimensions of the old rug are 8 fe

aliina [53]

The area of the old rug, we know, is 8 * 4 = 32 feet squared.

If we double the dimensions, we get that 8 becomes 8 * 2 = 16 and 4 becomes 4 * 2 = 8.

Then, the new area is 16 * 8 = 128 feet squared.

128/32 = 4, or choice (J).

The top and bottom ends of a windshield wiper blade are R = 24 in. and r = 14 in., respectively, from the pivot point. While in

Orlov [11]

Answer:

Area swept by the blade = 448 $in^{2}$

Step-by-step explanation:

The arc the wiper wipes is for 135 degrees angle.

So, find area of sector with radius 24 inches. And the find area of arc with r=14 inches.

Then subtract the area of sector with 14 inches from area of sector with radius as 24 inches.

So, area of sector with r=24 in = $\frac{135}{360} *\pi *24^{2}$

Simplify it,

=216 $\pi$

Now, let's find area of sector with radius 14 inches

Area of sector with r=14 in = $\frac{135}{360} *\pi *14^{2}$

Simplify it

=73.5 $\pi$

So, area swept by the blade = 216 $\pi$ -73.5 $\pi$

Simplify it and use pi as 3.14.....

Area of swept =678.584 - 230.907

=447.6769

Round to nearest whole number

So, area swept by the blade = 448 $in^{2}$

How to solve 45y to the second power plus 15y minus 10 ?

Lerok [7]

Answer:

Either y = $\frac{-2}{3}$ or, y = $\frac{1}{3}$

Step-by-step explanation:

We have to solve the following quadratic equation

45y² + 15y - 10 =0

Now, dividing both sides with 5 we get, 9y² + 3y -2 =0

Hence, to solve the above equation we have to factorize the left-hand part of the equation.

So, 9y² + 3y - 2 =0

⇒ 9y² +6y -3y -2 =0

⇒ (3y +2) (3y -1 ) =0

⇒ Either (3y +2) =0 or (3y -1) =0

⇒ Either y = $\frac{-2}{3}$ or, y = $\frac{1}{3}$ (Answer)
