It’s should 5x^2+7x+3 in standard form
m<P would be:
25
but m<PQC I forgot how to do... sorry!
Y=9x because if you divided y by x all the numbers will equal to 9 which is proportional
Answer:
22 hours (B)
Step-by-step explanation:
John's velocity = 55mph
Sally's velocity = 65mph
John's time taken = x
Sally's time taken = x - 4
since they must cover the same distance.
and, distance = vel × time
Sally's vel × time = John's vel × time
55x = 65(x-4)
55x = 65x - 220
-10x = -220
x = 22 hours.
Therefore, Sally catches up after 22 hours
t > 35 and t <40
So, Option A is correct.
Step-by-step explanation:
This is the question of compound inequality
Since the temperature of milk should be greater than 35 and the temperature should be less than 40 for keeping the quality of milk.
So, Representing it in inequality the union of both conditions we get:
t > 35 and t <40
So, Option A is correct.
