Find 3/4 of 16.
16 * 3/4
48/4
12
<span>So she uses 12 gallons of gas.</span>
For the lunch it would be 20$
Should be D. (5^2)^2= 5^4 (you multiply them) and 5^4+5^4=5^8
To answer this question you would start with 1 whole piece and break it into 4 equal pieces. Each piece would be 1/4 of the original.
If you used 3 of these, you are left with 1/4.
Out of the 1/4 leftover, you create 5 equal-sized pieces.
1/4 divided by 5.
1/4 x 1/5 = 1/20 of the original board for each.
Since angle QST is 45°, RQST is a square.
Therefore, QR = QT = 6.2
P.S. Good job trying to do Trigonometry tho :D
