Anna cuts four identical circles from a square piece of black poster board as shown. What is the area of the left over poster bo
nydimaria [60]
Formula for a circle: A=Pi*r^2
Diameter:2ft
Radius:1ft
A=3.14*1^2
A=3.14
Multiply by 4
4 squares=12.56ft squared
Formula for a square: A=s^2
A=4^2
A= 16ft squared
To find leftover you need to subtract 12.56 ft from 16 ft to get 3.44 ft squared(A).

At a rock concert, the ratio of girls to boys is 3:7. If there are 360 more boys than girls, how many girls are at the concert?
bixtya [17]
You could understand the ration as parts: the total number of parts was 3+7=10.

So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).

so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.

The digit in the tens place of a two digit number is three times that in the units place. If the digits are reversed the new num
S_A_V [24]
We could do it with algebra.  But we can also do it the long way, which is
shorter than the algebraic way.

The digit in the tens place is 3 times the digit in the units place.
So the number MUST be
31, or
62, or
93 .
It can't be anything else.

Now here they are again, with the reverse of each one:

31 . . . 13      The new number is  18 less.
62 . . . 26      The new number is  36 less.
93 . . . 39      The new number is  54 less.

Obviously, the original number is 62.
