Answer:

-21

Step-by-step explanation:

3x - 3y

x = -3

y = 4

Substitute the variables x and y in the equation with the numbers they represent.

3(-3) - 3(4)

-9 - 12

-21

None of the answers you have proposed are correct.

Determine whether the number is a perfect square 47
Ghella [55]
Perfect squares are n² where n is a whole number
whole numbers are like 0,1,2,3,4,5,6, etc
no decimal or fractions

we can do that be looking at the perfect squares we know
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
etc

so we see 47 is between 6² and 7²
therefor, for n²=47, n is between 6 and 7 and is therfore not a whole number
that makes 47 not a perfect square

Brine is a solution of salt and water. If a tub contains 50 gallons of a 5% solution of brine, how much water must evaporate to
vova2212 [387]
<span>Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 x = 18.75 lb of water evaporated : ; Check; amt of salt remains the same, only the percentage is different, right? .05(50) = .08(50-18.75) .05(50) = .08(31.25) 2.5 = 2.5</span>

A can of tuna fish is a cylinder with a height of 1.75 inches and a diameter of 3 inches. If the can is half full, how many cubi
zlopas [31]

Answer: 6.185in^3

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

V_{cylinder}=\pi r^2h

r is the radius of the cylinder and h is the height of the cylinder.

Given the diameter of 3 inches, calculate the radius of the cylinder with:

r=\frac{d}{2} (Where d is the diameter)

 r=\frac{3in}{2}=1.5in

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

V_{can}=\pi (1.5)^2(1.75in)=12.37in^3

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

V_{tuna}=\frac{V_{can}}{2}\\\\V_{tuna}=\frac{12.37in^3}{2}\\\\V_{tuna}=6.185in^3
