The correct surface area is 72 cm^2
Step-by-step explanation:
Esther didn't divide the area of the faces by 2.
The correct surface area is:
(4 * 4) + 4((4 * 7)/2)
16 + 4(28/2)
16 + 4(14)
16 + 56 = 72 cm^2
Answer:
n=65th term
Step-by-step explanation:
AP:3,15,27,39......
From the AP
a=3
a+d=15
a+2d=27
3+d=15 (1)
3+2d=27 (2)
Subtract (1) from (2)
We have,
2d-d=27-15
d=12
54th term=a+(n-1)d
=3+(54-1)12
=3+(53)12
=3+636
=639
The term is 132 more than the 54th term
132+54th term
=132+639
=771
Find the term
771=a+(n-1)d
771=3+(n-1)12
771-3=12n-12
768=12n-12
768+12=12n
780=12n
n=780/12
=65
n=12
The term which is 132 more than the 54th term is the 65th term
Eman is wrong heheheheheheehheherheheheehehrhehrhrhrh
Answer:
I’m not sure what the question is since you are just giving me the information, but I’m gonna tell you this:
History >> 2 hrs
Chem >> 30 mins
Alg 2 >> 1 hr 30 mins
Hope this helps!

Step-by-step explanation:
4 hours << total
Half her time on history>>4/2>>2 hrs on history
Leftover time>>4-2=2 hrs left
A fourth of leftover time on chem>>2hrs/4 = 30 mins on chem
What’s left? 2hrs - 30 mins= 1hr and 30 mins << leftover <<alg 2
