Answer:
Looks like a 0 to me, but i see where the A comes in.
Step-by-step explanation:
#1
3 1/2 +5 2/3
you would want to get these to have common denominators so you would multiply them, the lowest number they both can go into is 6 so you would have both of them go into that number. And they would equal
3 3/6 + 5 4/6 = 8 7/6
You can reduce this down to
9 1/6
__________________________________________________________
#2
2/5 (3/4)
you want to remove the parentheses so it would be
2/5 x 3/4
Then you will cross cancel the numbers (2 and 4)
1/5 x 3/2
then you want to multiply the fractions, and it would be.
3/5x2
and you multiply once again for your final answer
3/10
Answer #1: 9 1/6
Answer #2: 3/10
52 people
276 people
924 people
1,148 people
924 people rode the rollercoaster.
The answer is option (C).
The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying by 100.
The percentagechange is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
To find the number of people who rode the roller coaster,
We can multiply the total number of people at the park by the percentage who rode the roller coaster:
So,
The number of people who rode the roller coaster.
= 77% × 1,200
= 77/100 x 1200
= 924
Therefore,
924 people rode the rollercoaster.

Answer:
{-1, 3}
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x) = x^2 - 2x - 3.
To find the zeros of this quadratic, set it equal to zero first:
f(x) = x^2 - 2x - 3 = 0.
Now factor this result: (x - 3)(x + 1) = 0.
The zeros are {-1, 3}
