A roast requires 3 hours and 40 minutes in the oven to be cooked. In order to have the roast ready to serve at 6:30 PM, it must be put into the oven at

2:50 PM

Step-by-step explanation:

Step 1: State what is given

Roast takes 3 hours and 40 minutes or 220 minutes

Need the roast to be done by 6:30 PM

Step 2: Subtract 3 hours from 6:30

6:30 - 3:00

3:30 PM

Step 3: Subtract 40 minutes from 3:30

3:30 - 40

2:50 PM

Therefore the roast needs to be put into the oven at 2:50 PM

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
