Answer: Forgot to divide at the end
Step-by-step explanation:
To figure out your friend's error, solve the equation yourself.
- Distribute the 5 to get 25x+30
- Combine like terms in the first equation toget 25x-3=25x+30
- Add 3 to the other side.
When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.
Surface area = πr² + 2πrh
Surface area = π(6)² + 2π(6)(12) = 180π cm²
Answer: 180π cm²
Seems to be a geometric sequence which is found by
an=nth term
a1=first term
r=common ratio
first term is 0.75
it doubles each time so common ratio is 2
to find the nth term, input n and evaluate
example
to find the 20th term
just to find the kth term, input k for n in
Answer:
y = (-3/2x) + (35/4)
Step-by-step explanation:
So the perpendicular line will have a slope that is the opposite reciprocal of the other line's slope. Solve for the original line's slope first:
2x - 3y = 7 --> -3y = -2x + 7 --> y = (2x/3) - (7/3)
So, the slope of the perpendicular line will be (-3/2x)
Solve for the y-intercept of the perpendicular like by using the linear equation and substituting in (2,8):
8 = (-3/(2*2)) + b --> (32/4) = -(3/4) + b --> b = (35/4)
So, y = (-3/2x) + (35/4)
Hope that helps! :D
That is a strangely worded question... but I think you're asking how many people said they got a 6 but did not.
So, a dice that has 6 sides has a 1/6 chance of Landing on a 6. so 1/6 of 360 should be that 60 people got a 6. Therefore 119-60 = 59.
The proportion is 59/360 that lied
