The length of wrapping paper piece is 10 inches and width is 15 inches.

Step-by-step explanation:

Let,

Length of rectangular piece = x

Width of rectangular piece = y

Perimeter = 50

2(x+y) = 50

Dividing both sides by 2

\frac{2(x+y)}{2}=\frac{50}{2}\\x+y=25\ \ \ Eqn\ 1

x+y=25   Eqn 1

The length was 5 less than the width.

x = y-5   Eqn 2

Putting value of x from Eqn 2 in Eqn 1

(y-5)+y=25\\y-5+y=25\\2y=25+5\\2y=30

Dividing both sides by 2

\frac{2y}{2}=\frac{30}{2}\\y=15

Putting y=15 in Eqn 2

x=15-5\\x=10

The length of wrapping paper piece is 10 inches and width is 15 inches.

Step-by-step explanation:

The volume (V) of a pyramid is

V = \frac{1}{3} area of base × height, hence

V = \frac{1}{3} × 96 × 15 = 32 × 15 = 480

3 times a number is 54 less than the square of that number. Find the negative solution.
son4ous [18]

Answer:

-6

Step-by-step explanation:

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

n(n - 9) + 6(n - 9) = 0

(n - 9)(n + 6) = 0

n = 9 , -6

The circumference of the hub cap of a tire is 83.96 centimeters. Find the area of this hub cap. Use 3.14 for . Use pencil and pa
Bess [88]

Answer:

Area = 561.2485 square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Step-by-step explanation:

As we know the circumference of a circle is 2\pi r

The radius of the hub cap needs to be devised to determine the area

83.96 = 2* 3.14*r

r = \frac{83.96}{2*3.14}

r = 13.37 centimeters

Area of the hub cap = \pi r^{2}

Substituting the devised value of r in the above equation, we get -

3.14 * 13.37^2\\

561.2485 square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
