Answer:
Therefore, the budget is 656.76$.
Step-by-step explanation:
We know that a lab orders a shipment of 100 rats a week for experiments that the lab conducts. Suppose the mean cost of the rats turned out to be $ 12.63 per week. We calculate budget of a lab for the next year's.
We know that 1 year have 52 weeks. We get
52 · 12.63 = 656.76
Therefore, the budget is 656.76$.
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

Answer:
The 40-ounce jar of peanut butter is cheaper per ounce.
Step-by-step explanation:
30-ounce jar:
6÷30=0.2
40-ounce jar:
7.2÷40=0.18
Woah! A 29-gon. Impressive!
Sum of angles = 180(n-2) [where n is equal to the number of sides]
180(29-2)
180(27)
The sum of the interior angles of a regular 29-gon is 4860 degrees.
Hope that helps!
