Answer:
c=93
Step-by-step explanation:
35+3(x+2)+52=180
87+3(x+2)=180
87+3x+6=180
93+3x=180
3x=180-93
3x=87
x=87/3
x=29
3(29+2)
3(31)=93

Answer:
92.5
Step-by-step explanation:
The total of Megan's scores is ...
94 +81 +87 +93 = 355
so her current average is 355/4 = 88.75
The score (s) Megan needs for a 90 average is ...
(2/3)(88.75) +(1/3)s = 90
2(88.75) +s = 270 . . . . . . . . multiply by 3
s = 270 -177.5 = 92.5
Megan needs a score of 92.5 on her final to have an overall average of 90.
The answer would be -40 / 3 or -13.3333333333
Answer:
408 sq. in.
Step-by-step explanation:
The total surface area of the pyramid is the sum of all 4 faces (each of them a triangle) and square base.
Triangle area is 
where b is base and h is height.
base of triangle is 12 and height is 11
So area of each triangle is 
There are 4 of them, so total is 66 * 4 = 264
Now, square has an area of 
where s is the side length.
It is given s = 12, so the area of the square base is:
Total Surface Area of the Pyramid is 264 + 144 = 408 sq. in.
