Dave is three times as old as his sister. In seven years the sum of their ages will be 38. How old are they now?
bija089 [108]

Answer:

Dave is 18 and his sister is 6.

Step-by-step explanation:

If you do 38 -7x2 you can work out the combined ages of them now which is 24 (you have to do 7x2 because there are two of them and its seven years in the future). Then you can work out their ages using a ratio. Dave’s age : his sister’s age is 3:1 so if you divide 24 by 4 (3+1 = 4 so your can work out one portion of their age) you can find out how old the sister is which is 6. Times that by 3 to get Dave’s age which is 18. A formula for this (where x is his sisters age) would be 3x=38-7x2 which cancels down to 6.

Answer:

The probability that a point randomly chose in the rectangle is in the triangle is \frac{1}{8}, so the answer would be A

Step-by-step explanation:

To find the probability of a random point being in the triangle, we must find the area of the triangle and the area of the rectangle.

The area of the rectangle can be found by multiplying the width by the height, so the equation would be

8 *4 = 32

The area of the the triangle can be found by the formula A = \frac{1}{2} bh

This means that the equation would look like

\frac{1}{2} *2*4=4

Now that we have both the area of the triangle and the rectangle, we can create a ration of the area of the triangle to that of the rectangle. It would look like this

\frac{4}{32}

This would simplify to \frac{1}{8}
