A father is 60 years old and his son is half his age. How old was the boy when his father was four times his age?

So, if the father is 60, his son is half his age, which would be 30.

So, to find out how old the boy was when his father was 4 times his age, you would do, 30 divided by 4 (I believe).

You then should get, 7 1/2 years old the boy is.

Hope this helps! Have a great rest of your day! c:

740 square meters

Just find the areas of all the faces of the prism. And add then all up:

Area of rectangular base (bottom):
16 • 10= 160 square meters

Area of triangle facing front:
1/2 • 15 • 16= 120
Multiply 120 by 2 cause theres a same triangle facing back the prism: 120 • 2= 240

Area of rectangle facing right:
10 • 17= 170
Multiply 170 by 2 cause theres a same rectangle facing left the prism: 170 • 2= 340

Add them all up together:
160+ 240+340= 740

When x=2 and y=3, which expression has the smallest value?<br> x-y<br> x(y)<br> x+y <br> x/y
Archy [21]

Answer:

  x - y = -1

Step-by-step explanation:

The value of the first expression is negative:

  2 - 3 = -1

All of the other expressions give positive values, so are larger.

The expression with the smallest value is x-y.

_____

If x(y) is supposed to mean x^y, the exponentiation operator is needed. Otherwise, it is interpreted as x·y.
