1. We don't know the meaning of "{There is a box image here}".
If you're dealing with congruent figures, match the corresponding letters in the name of the figure:
.. E F G H
.. Q R S T
If you're concerned with QT (1st and 4th letters), you need to look at EH (1st and 4th letters).
If EFGH ≅ QRST, then QT = EH = 6.3.
2. LM = ST = 5.2
Answer:
The salt concentration of the mixed solution = 10%
Step-by-step explanation:
First assuming that the concentration of salt given is on a vol% basis.
First solution has 0.7 gallon of 5% salt
Amount of salt in this solution = 5% × 0.7 = 0.035 gallon
Second solution has 0.3 gallon of 22% salt
Amount of salt in this solution = 22% × 0.3 = 0.066 gallon
Total amount of salt in the resulting solution = 0.035 + 0.066 = 0.101 gallon
Total volume of the resulting solution = 0.7 + 0.3 = 1.00 gallon
Concentration of the mixture of salt = (0.101/1) = 0.101 = 10.1% = 10% to the nearest percent
