Step-by-step explanation:
Answer:
x = 45
Step-by-step explanation:
The average is calculated as
average = 
here the average = 50 , thus
= 50
Multiply both sides by 4
36 + 44 + 75 + x = 200
155 + x = 200 ( subtract 155 from both sides )
x = 45
Answer:
30 days(To the nearest tenth of a day)
Step-by-step explanation:
In this question, we are asked to give the number of days that a baby whale had grew to a size given the rate at which it grows per day.
We have been told that after the first day, it started growing to a point of 47.075 inch at a rate of 1.5 inch a day.
The number of days taken for this growth can be calculated by dividing the present size by the daily growth rate.
Mathematically, that is 47.075/15 = 31.38333
Now, we are told to convert this to the nearest tenth of a day. The value here should thus be 30.
Answer: 4.25
Step-by-step explanation:
2(d-3) + 22d= 120-24
2d - 6 + 22d= 96
2d +22d= 96+6
24d= 102
d= 102/24
d= 4.25
