Step-by-step explanation: The total number of pizzas is 12 + 18 = 30. Mitchel bought 12 of those 30 pizzas. To find the percentage you do the portion/total. Thus 12/30 = 0.4, as a proportion. To turn a proportion into a percentage simply multiply by 100. 0.4 * 100 = 40%
Answer:
3,468?
Step-by-step explanation:
I think the prompt is a little confusing, but I went with the logic of literally using the numbers and combining them.
The journey is broken down into five segment
Shop - first delivery =

miles
First delivery - second delivery =

Second delivery - third delivery =

Third delivery - fourth delivery =

Fourth delivery - shop =

The average distance for each segment are:
![[12 \frac{1}{3}+8 \frac{3}{4}+17 \frac{2}{8}+23 \frac{2}{3}+10 \frac{5}{10} ]](https://tex.z-dn.net/?f=%5B12%20%5Cfrac%7B1%7D%7B3%7D%2B8%20%5Cfrac%7B3%7D%7B4%7D%2B17%20%5Cfrac%7B2%7D%7B8%7D%2B23%20%5Cfrac%7B2%7D%7B3%7D%2B10%20%5Cfrac%7B5%7D%7B10%7D%20%5D%20%20%20%20)

(all answers are c)
S = p/(q +p -pq)
q +p -pq = p/s
q -pq = p/s - p
q(1-p) = p/s - p
q = (p/s - p) / (1-p)
