Answer:

Emily is 17

Step-by-step explanation:

If Jamie is 47 and she is 4 less than 3 times older than Emily, you want to start by doing the opposite of each identifying word. Remember to work backwards. 4 less means minus 4, but you want to do the opposite so you will add 4 to 47. 47 + 4 = 51 Then if it says 3 times this mean multiplication but again, we wanna do the opposite so 51 ÷ 3 = 17

To check it Multiply 17 by 3 and then subtract 4. 17*3=51 51-4=47

Find the height of a cylinder that has a radius of 5 m and a volume of 450 mº.
jekas [21]

The height of cylinder is 5.73 meters.

Further explanation:

Given

Volume\ of\ cylinder=V=450\ m^3\\Radius=r=5\ m

The formula for calculating volume of cylinder is:

V=\pi r^2h

Putting the values of volume, radius and pi

450=3.14*(5)*h\\450=3.14*25*h\\450=78.5*h\\h=\frac{450}{78.5}\\h=5.73\ meters

The height of cylinder is 5.73 meters.

Keywords: Volume of cylinder, Surface area of cylinder

The value of x from the given expression is -2

<h3>Slope of a line</h3>

The formula for calculating the slope of a line is expressed as:

Slope = y2-y1/x2-x1

Given the following parameters

m = 1

(x1, y1) = (0, 2)

(x2, y2) = (x, 0)

Substitute

1 = x-0/0-2

1 = x/-2

x = -2

Hence the value of x from the given expression is -2
