QUESTION POSTED AT 20/02/2020 - 11:19 PM

The answer to this question would be:
Jim     =6 years
Harry =2 years

To answer this question, you need to translate the description into a  mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J
2. (J+2)= 2(H+2)
J+2= 2H+4
J= 2H +2

If you put the 1st and 2nd equation together, the result would be:
H+4= J
H+4= (2H +2)
H-2H= 2-4
-H= -2
H=2

After that insert the H value to either 1st or 2nd equation.
H+4= J
2+4=J
J= 6

### Simplify the expression. Write the answer using scientific notation. Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles. Suppose a star is 13.4 light-years from Earth. In scientific notation, how many miles away is it?

So u will do 13.4*5880000000000=78,792,000,000,000 is how many miles away it is

### Find the volume V of the cone

V=πr^2(h/3)
V≈804.25

Since the height is 12, and radius is 8, take the radius and square it. 8 squared equals 64. Now, take the height (12) and divide that by three. This equals 4.

So Volume = Pi times 64 times 4. The answer should be 804.247. Once rounded, you should get 804.25

### Find the area of the shaded portion of the diagram (use 3.14 for p).A)220.16 square yardsB)6.88 square yardsC)55.04 square yardsD)13.76 square yards

Get the area of the circle. Use this formula:

We know the radius is 4 yards.

Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is
Area = side^2

Area = 8^2
Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So,
D) 13.76 square yards is the answer to this question.

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis.

The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38 The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78.
