Answer:
There are 100 seats that are next to a window.
Step-by-step explanation:
You have to calculate 20% of the total number of seats.
20% can also be written as 20/100
so 20/100 x 500. If you solve this then you will get 100. Therefore, 100 seats are next to a window.
Answer: 100 seats are next to a window.
Step-by-step explanation: 1. We assume, that the number 500 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 500 is 100%, so we can write it down as 500=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 500=100%
2) x=20%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
500/x=100%/20%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 20% of 500
500/x=100/20
(500/x)*x=(100/20)*x - we multiply both sides of the equation by x
500=5*x - we divide both sides of the equation by (5) to get x
500/5=x
100=x
x=100
now we have:
20% of 500=100
Heidi drove to visit her friend one summer. The miles she traveled are shown on the graph below.
What is the unit rate of miles driven per hour?
A.
50 miles per hour
B.
25 miles per hour
C.
75 miles per hour
D.
100 miles per hour
Answer:
A
Step-by-step explanation:
Look at the line and wherever the line meets with the miles then find the miles and that's your answer.
If you want to make sure, do "50(mph) * 2(hours)" and it should land on "100"
Find the ordered pair (x,y) that satisfies the system of equations
x + y = 15
x - y = 3.
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)

In a parking lot there are only white cars, green cars, and red cars. If one car is selected at random from the lot, the probability that the selected car would be a green car is one sixth and the probability that it would be a red car is one eighth. What is the probability that it would be a white car?
Answer:
17/24
Step-by-step explanation:
With the understanding that the three given cars form three mutually exhaustive and disjoint sets i.e., they form the partition of sample space, the probability that the selected car would be white is [tex]\frac{17}{24}[/tex].
What is partition of a sample space?A collection of sets B1, B2, . . . , Bn is said to partition the sample space if the sets (i) are mutually disjoint and (ii) have as union the entire sample space.
In this question, we take three sets - set of all red cars, white cars and green cars.
A car can be either red, white or green. Thus they are mutually exclusive.
Also, let the cars in parking lot be the sample space. Every car we pick has to be of one of the three colors. This imply that the three sets of the three cars are mutually exhaustive.
P(selecting a red car) + P (selecting a green car) + P(selecting a white car) = 1
[tex]\frac{1}{8} + \frac{1}{6} + P(selecting\ a\ white\ car) = 1\\\\ P(selecting\ a\ white\ car) = \frac{17}{24}[/tex]

Answer:
c
Step-by-step explanation:
subtract 5.4 from 9.9 to get the length of the triangle then multiply by 3.3 and 1/2 to get the area of the triangle then add that to the area of the rectangle by multiplying 5.4 by 3.3
4.5 x 3.3 x 1/2 = 7.425
5.4 x 3.3 = 17.82

Use the given information to write an equation of each parabola.
The parabola has focus (-8.0) and vertex at the origin
Step-by-step explanation:
use y^2=4px
p is the distance from the vertex to the focus, which is 8 units left
y^2=4(-8)x
y^2=-32x
Use y²=4px where p is the distance from the vertex to the focus,
p = 8 to the left,
so p = -8
Plug that in:
y² = 4(-8)x
Sole / simplify / multiply:
y² = -32x

5x-2 = -2+5x. a) infinite solution b) no solution c) 1 solution
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The given equation is :
[tex]5x - 2 = - 2 + 5x[/tex]here, 5x is on both sides, so they cancel out. hence value of x can't be determined.
so, the equation have no solution.
correct choice is B.) no solution
5x -2 = -2 + 5x
Add 2 to both sides to get 5x = 5x
Because this is true then any value of x will still make the equation true.
This means there are infinite solutions.
Answer: a) infinite solution

Answer: [tex]y = \frac{1}{3}x-2[/tex]
This is the same as writing y = (1/3)x - 2
Slope = 1/3
y intercept = -2
======================================================
Explanation:
We first need to determine the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-3-3}{-3-15}\\\\m = \frac{-6}{-18}\\\\m = \frac{1}{3}\\\\[/tex]
Then we'll use this value of m, along with (x,y) = (15,3), to determine the y intercept b value.
[tex]y = mx+b\\\\3 = (1/3)(15)+b\\\\3 = 5+b\\\\3 - 5 = b\\\\-2 = b\\\\b = -2[/tex]
You could use the other point (-3,-3) as well
[tex]y = mx+b\\\\-3 = (1/3)(-3)+b\\\\-3 = -1+b\\\\-3 +1 = b\\\\-2 = b\\\\b = -2[/tex]
Either way, we end up with the same y intercept. You don't need to show both sets of steps when computing b. You only need to pick one set of steps.
Since m = 1/3 and b = -2, we go from y = mx+b to y = (1/3)x - 2 which is the same as writing [tex]y = \frac{1}{3}x-2[/tex]
Answer:
y = 7/18 - 11/6
Step-by-step explanation:
y2 - y1 / x2 - x1
-3 - 4 / -3 - 15
-7/-18
= 7/18
y = 7/18x + b
4 = 7/18(15) + b
