Answer:
Step-by-step explanation:
the disc. is the part under the root in the general formula
which is equal b^2 - 4 x a x c
in this equation a = 1 " coefficient of x^2"
b = 0 "coefficient of x which isn't found here "
c = 12 " the absolute "
[tex]0^{2} - 4[/tex]×[tex]1[/tex]×[tex]12[/tex] = -4×12 = something i don't have a calculator
but it will be negative so the roots will be complex and unreal

The Extreme Rock Climbing Club planned a climbing expedition. The total cost was $4600, which was to be divided equally among the members going. Prior to the trip,
10 members decided not to go. If the cost per person increased by $230, how many people went on the expedition?
Let x = number of people that were supposed to go to the trip, where x is greater than or equal to 0.
Let y = price per person initially with x people going on the trip.
xy = 4600
Solve for y.
y = 4600/x
(x - 10)(y + 230) = 4600
Replace y with the fraction 4600/x.
(x - 10)[(4600/x) + 230)] = 4600
What you need to do:
1. Solve (x - 10)[(4600/x) + 230)] = 4600 for x.
2. When you find x, subtract 10 from the value of x to find the number of people that went on the expedition.
You finish.

What is 35% of 80? use the if/of formula
Answer:28
Step-by-step explanation:
10%= 8
35%/10%= 3.5
8 x 3.5 = 28
Answer:
28
Step-by-step explanation:
80/x=100/35
(80/x)*x=(100/35)*x - we multiply both sides of the equation by x
80=2.85714285714*x - we divide both sides of the equation by (2.85714285714) to get x
80/2.85714285714=x
28=x
x=28
now we have:
35% of 80=28

C = 7 cm and a = 4 cm
b= _____ cm
Answer:
√33 cm
Step-by-step explanation:
We know that this is a right triangle, which means that we can apply the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 4 and c = 7, so plug thes in to find b:
a² + b² = c²
4² + b² = 7²
b² = 49 - 16 = 33
b = √33
The answer is thus √33 cm.
Determine the number that can be used in place of the question mark to make the equation true.
49^? = 7

40 percent of students in a class of 35 students are girls. how many girls are in this class?
Answer:
14 girls
Step-by-step explanation:
40% of 35 = [tex]\frac{40}{100}[/tex] × [tex]\frac{35}{1}[/tex] [tex]\frac{40}{100}[/tex] × [tex]\frac{35}{1} = \frac{1400}{100}[/tex] [tex]\frac{1400}{100} = \frac{14}{1} = 14[/tex]I hope this helps!
Answer:
14 girls in the class
Step-by-step explanation:
use percentage equation, p = nw or part of the question = the percentage times the total amount.
So in this case our p, or girls in the class (which is part of the total), is unknown. We have the percentage and we have the total. So all we need to do is multipy them. However how do you multiply percentage . . . well 40 percent also equalts to 0.40. So all you have to do is multiply .40 by 35 and you have your answer.

Given that for all values of x,
f(x) = 4x + p
g(x) = px + 1
and fg(x) = 12x + q
where p and q are constants.
Work out the values of p and q.
Answer:
Step-by-step explanation:
p = 3
M also looking for q.
If f(x) = 4x + p, g(x) = px + 1 and fg(x) = 12x + q. The value of p and q are 4 and 7.
What is Function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)
f(x) = 4x + p
g(x) = px + 1
and fg(x) = 12x + q...(1)
So f(g(x)=4(px+1)+p
=4px+4+p...*
Comparing * with (1).
4p=12
P=3
q=4+p
q=4+3
q=7
Therefore p is 3 and q is 7.

A baseball team has won 8 out of the first 20 games and has 40 games remaining. The team needs a winning percentage of 62.5% make the playoffs. How many more wins does the team need in order to get into the playoffs? If the team wins the number of games to get into the playoffs, what is the final win percentage if the team wins 2 and loses 3 games in the playoff?
Answer:
30 More Games for Playoffs | Win Percentage of 40% in Playoffs
Step-by-step explanation:
We find the total amount of games by adding first 20 and 40 remaining
This will leave us with 60 games
In order to calculate the playoff, we would have to calculate 62.50% in those 60 games.
62.50% is 5/8, we divide 60 by 8 and get 7.50
We multiply both sides by 7.50 and get 37.50/60
We subtract 8 from 37.50 and get 29.50
We round it to the nearest ones and get 30
In order to win the game they would need to win 30 more games
To calculate the final win percentage, we would add 2 and 3, which would give us 5.
After winning 2 and losing 3,
it would give us 2/5,
which in percentage is 40%

Step-by-step explanation:
The y-intercept is point on the y-axis that the line passes through.
You can see the line passes through 3 on the y-axis.
On the y-axis, every point has a 0 for the x-coordinate.
The ordered pair for the point that is 3 on the y-axis is (0, 3).
