So what will it be a percentage of? it will be the percentage of the original recruits, of the original 150.
for this, we need to divide the number of recruits that left over all recruits, and multiply by 100%:
so the number of trainees decreased by 20 %
A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.
Answer:
Step-by-step explanation:
This first step is to take the square root of the minus which is understood to be - 1
sqrt(-1) = i
So far what you have is
sqrt(-98) = i*sqrt(98)
sqrt(98) is just found the ordinary way
sqrt(98) = sqrt(7*7*2)
sqrt(7*7*2) = 7*sqrt(2)
Answer: 7 * i * sqrt(2) = i7*sqrt(2)
Pick the choice that looks like what you have done for homework.
