Integer generally means number.
if s = seconds then
2s = 18
solve for s,
18/2 = 7
s = 7 seconds
Answer:
Correct option A
Step-by-step explanation:
Average rate = 260/4 = 65 mph
It increases by 12mph
So 65+12 = 77 mph
Correct option A
Answer:
g = At/60
Step-by-step explanation:
Given:
A = 60(g/t)
60(g/2) is a mistake in the question which the question has corrected in the comments)
A is the average for a professional hockey goalie.
g is the number of goals scored against the goalie.
t represents the time played in minutes.
Finding 'g':
A = 60(g/t)
can be written as A = (60*g)/t
Multiplying by 't' on both sides:
At = (60*g)*t/t
At = 60*g
Dividing by '60' on both sides:
At/60 = 60*g/60
At/60 = g
⇒ g = At/60
Let x lb be the weight of a box. Since 152-lb person, a 15-lb weight, and a box are on the ladder without breaking it and the ladder holds 220 lb, then
152+15+x≤220.
Solve this inequality:
167+x≤220,
x≤220-167,
x≤53 lb.
The maximum weight of the box can be 53 lb.
