The hole for a support needs to be 5 feet deep. It is currently 1 foot and 9 inches deep. How much deeper must the hole​ be

3 foot 3 inches

Step-by-step explanation:

How much deeper the hole should be = intended depth - current depth

Convert feet to inches for easy calculation

1 ft = 12 inch

5 x 12 = 60 inches

1 foot = 12

12 + 9 = 21 inches

60 - 21 = 39 inches

convert inches to feet

39 /12 = 3 feet 3 inches

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)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
