Answer:
Approximately 42.
Exact sum is 42 13/40.
Explanation:
Estimate 11 3/8: 11
Estimate 9 7/10: 10
Estimate 21 1/4: 21
Add them together: 42.
11.375 + 9.7 + 21.25 = 42.325
I made them into decimals and then will convert it into fraction.
42.325 = 42 13/40
Hope this helps!
Answer:
10√3 feet
Step-by-step explanation:
In a 30-60-90 triangle;
-Long leg = long leg
-Short leg = 1/2 * long leg
-2nd longest leg = short leg * √3
-Long leg = 20
-Short leg = 1/2 * long leg = 10
-2nd longest leg = short leg * √3 = 10√3

Answer:
The increment in the model is 106cm
Step-by-step explanation:
Given


Required
Determine the increment
To do this, we simply subtract the initial height of the building from the final height



<em>Hence, the increment in the model is 106cm</em>
First, you'd find the mean of all the numbers by doing 10+9+16+5+10 = 50/5 = 10. Second, you'd subtract all values from the mean by doing
16 - 10 = 6
10 - 10 = 0
10 - 10 = 0
10 - 9 = 1
<span>10 - 5 = 5
Lastly, finding the mean of all 5 numbers would be, 2.4! Hope this helps!! :D</span>
