There are 143 people in an audience. Out of this number, 63 are female. What percent of the people in the audience are male?

Lerok [7]

143-63=80. There is 80 males in the audience. So you divide 80 and 143:

80/143

then you multiply the answer by a 100:

(80/143)*100

80/143=0.55944055944

Multiply that number with a 100 which is 55.94

the answer 55.94% or you can simplify which is 56%

The perimeter of a rectangle is 40 inches. The table shows some of the possible dimensions for the length and area of the rectan

Mama L [17]

Answer:

Therefore the Dimensions are

Length =18 inches and Width = 2 inches

Length =2 inches and Width = 18 inches

Step-by-step explanation:

Let the Width of rectangle be 'W' inches.

The length of a rectangle be 'L' inches.

Area of rectangle given is 36 square inches.

Perimeter of Rectangle is 40 inches.

To Find:

Length = L = ?

Width = W = ?

Solution:

Perimeter of Rectangle is given as

$\textrm{Perimeter of Rectangle}=2\times (Length +Width)$

Substituting we get

$40=2(L+W)\\\\L+W=20\\\therefore L=20-W$

We have area of rectangle given as

$\textrm{Area of Rectangle}=Length\times Width)$

Substituting the given values we get

$36=(20-W)\times W\\W^{2}-20W+36=0$

Which is a Quadratic Equation, So by Splitting the middle term we get

$W^{2}-18W-2W+36=0\\W(W-18)-2(W-18)=0\\(W-2)(W-18)=0\\\therefore W=2\ inches\ or\ W =18\ inches$

Therefore the Length will be

$L=20-W=20-2=18\ inches\\OR\\L=20-18=2\ inches$

Therefore the Dimensions are

Length =18 inches and Width = 2 inches

Length =2 inches and Width = 18 inches
