You always have to find the LSA (lateral surface area) first.
(which is the shape's area combined w/out the bases.)
rectangle A would be 60 and so would rectangle C
rectangle B would be 96
if u add them all together that would be 12.5
Now you have to find the TSA (total surface area).
(which is the TOTAL net combined w/ bases)
the bases would be 7.5
7.5 x 2 is 12.5
Add the LSA and the TSA
216+12.5=228.5
<u>so the overall answer would be 228.5cm</u>
i hope this helps!!
Answer:
For mean
To show the mean of height measures for 40 students, you need to write-out exactly 40 heights into a calculator and add them up.
Then divide that total number by 40.
Step-by-step explanation:
Eg for 4 students
5 , 5.1, 5.2, 5.7 = 21ft
21/4 = 5.25ft.
Apply the same method but use 40 measures in addition for calulator or long addition. Then divide by 40.
2050=.34x-623.67
2673.67=.34x
x=2673.67/.34
x= 7863.74
x~ 7864
Answer:
D
Step-by-step explanation:
To compare the two, get the same denominator, so multiply -8/18 by 27 on the numerator and denominator, and multiply -17/27 by 18 on the numerator and denominator. That gives -216 /486 and -306 /486. On a number line, the one on the left is less. That greater than symbol is correct. Both to the left of 0, -8/18 on the right of -17/27.
