348 rocks because if you add 126 three times, or multiply it by 3, it equals 348. The numbers from the box you would use are 300, 30, and 18 then add them together
The diagonal is solved by a^2+b^2=c^2
c=8 in this problem, so c^2=64
Since the figure is a square, a must equal b.
64/2=32, each side is root of 32 units
the square root of 32 is approximately 5.66.
Ok
1/9=1present
3hours=xpresent
1/9 times x=3
multiplyboth sides by 9
x=27
answer is 27
another way is
1/9 hour=1 present
1hour=9present
3 hour=27 present
Kate has $37, Mary has $48, and Amy has $74.
<h3><u>Equations</u></h3>
Given that Mary, Kate and Amy have a total of $159, and Mary has $11 more than Kate, while Amy has twice as much money as Kate, to determine how much money each girl has, the following calculation must be performed:
- M = K + 11
- A = 2K
- K = K
- K + 11 + 2K + K = 159
- 4K = 159 - 11
- K = 148 / 4
- K = 37
So Kate has $37, Mary has $48, and Amy has $74.
