Answer: 1) The missing length is 40. 2) The missing side is 30 .
Step-by-step explanation:
1) 9^2 + b^2 = 41^2
81 + b^2 = 1681
-81 -81
b^2 = 1600
b= 40
2) 24^2 + 18^2 = c^2
576 + 324 = c^2
900 =c^2
c= 30
Answer: 7.5 batches
Step-by-step explanation:
60/6 is 10, so she needs to make 10 batches in total.
10-2.5=7.5
3,6.5,61.5,11,23 that is the pattern of 3's
1. The square root is about 1.73
2. The square root is about 1.41

Your answer is
$130.90
Note: We multiply by 70/100 because of the 30% discount. 100 - 30 = 70. So we have to multiply by 70%.
Also, we multiply by 105/100 because there is 5% tax. The tax means that we have to pay more which means 100 + 5 = 105.
Hope this helped :D
