This seems like a personal question
Answer:
Step-by-step explanation:
Let number of large pizzas be l and number of small be s.
<u>Then we have equations:</u>
- l + s = 100
- 16l + 11s = 1550
<u>From the first equation, we get l = 100 - s and substitute in the second equation:</u>
- 16(100 - s) + 11s = 1550
- 1600 - 16s + 11s = 1550
- 5s = 1600 - 1550
- 5s = 50
- s = 10
Number of small pizzas is 10
Question 10
30-2=28
28*2= 56
56*2= 112
120*2= 240
240+112=352.
Area = 352 square feet
Question 11
Volume = pi*r*r*h
=3.142*2.5*2.5*0.5
= 9.817
From the choices the answer is
D. 9.8 cubic ft
There is a 25% decrease because the decrease is 30, which is 25% of 120.
