Answer:
The answer would be A)98.
I got this by taking the 3 test scores that were provided and adding them then subtracting that by 360 (90x4 - which would give you a 90 in the end) so I had 360 - 262 which equaled 98 and that would be the score needed to have a 90 in the end.
Answer:
2 pi*r^2 + 2 * pi *r * h
Step-by-step explanation:
I will assume that you are looking for surface area
We need to find the area of the top and the bottom, which is the area of a circle
top: pi * r^2
Bottom: pi r^2
Then the side which is the circumference times the height ( it is a rectangle)
side: 2 * pi *r * h
Add them together to get the surface area
SA = pi * r^2 + pi * r^2 + 2 * pi *r * h
= 2 pi*r^2 + 2 * pi *r * h
I think it is 66 not for sure tho thats my answer <span />
I believe its 4. Hope it helped!
X represents the number
4x+13=(1/2)x-8 this is the equation
4x-(1/2)x=(-8)-13 combine like terms
(3 1/2)x=-21 simplify!
(7/2)x=-21 convert 3 1/2 into a fraction
x=(-21)(2/7) multiply both sides by 2/7 in order to isolate x
The answer is X= -6
