A soup can has a diameter of 4 inches and the height of the can is 7 inches. Desiree needs to design a label for the soup can. A

Hoochie [10]

Answer:

87.96 square inches

Step-by-step explanation:

The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area

Use the formula, LA = 2 $\pi$ rh

The diameter is 4 inches, so the radius is 2 inches

Plug in the radius and height into the formula, and solve:

LA = 2 $\pi$ rh

LA = 2 $\pi$ (2)(7)

LA = 28 $\pi$

= 87.96

So, the label will take up approximately 87.96 square inches

How many ways can a committee chairman choose 4 people for a subcommittee if there are 12 members on the whole committee?

Marina86 [1]

A group of k elements can be chosen from a group of n elements in $\frac{n!}{k!(n-k)!}$ ways.

$(^{12} _4)=\frac{12!}{4!(12-4)!}=\frac{12!}{4! \times 8!}=\frac{8! \times 9 \times 10 \times 11 \times 12}{2 \times 3 \times 4 \times 8!}=\frac{9 \times 10 \times 11 \times 12}{2 \times 3 \times 4}= \\ \\
=3 \times 5 \times 11 \times 3=495$

The answer is B. 495.

SOLVE THE SIMULATENOUS EQUATIONS Y=X-2 AND Y= 3X+5

natta225 [31]

Answer: y = x-2

y = 3x + 5

x-2 = 3x+5

x+3x = 5+2

4x = 7

x = 7/4

y = x-2

y = 7/4 - 2

y = 7-8/4

y = -1/4
