Identify the slope, y-intercept, and write an equation (don't add spaces):
You and your friends go to the movies and buy a large bucket of popcorn containing 682 pieces of popcorn. As a group, you consume 40 pieces of popcorn every minute.
Answers
Equation: 682 = 40x
Slope = 40 (or 40/1)
Y-intercept = 0
In this case,
y = the total
x = the amount of minutes
y-intercept = 0, since there isn’t a b in the equation.
slope = 40, because y = mx + b is 682 = 40x
This should be correct, unless there is missing information in the question.
Equation of expression
[tex]\\ \tt\hookrightarrow y=40x+682[/tex]
Compare to y=mx+b
Slope=m=40Y intercept=b=682Z(0,-5) Go left 5, up right, and down 3.
Answers
Answer:
I believe the answer is -4, -7. This would be the case if it meant to go up once and right once. However, the answer could also be -2, -5. This would be the case if it meant going up, right, and down each three times.

Ezra has $30 to spend on a taxi ride. The taxi company charges a flat rate of $8, plus $2.00 per mile. What is the maximum amount of miles Ezra can afford to travel in this taxi?
-I need this as quick as possible!
Answers
Answer:
11 miles
Step-by-step explanation:
Start by figuring out how much of the money, excluding the flat rate, can be used for mileage:
$30-$8=$22
So $22 can be used for mileage
Divide your mileage total by the amount per mile:
$22÷$2/mile=11 miles
Ezra can travel up to 11 miles

as such, since the diameter is 10 in,
radius = 10/2 = 5 in
Answer:
Step-by-step explanation:
The area of a 10-inch circle is 78.54 square inches. Using the formula A = 1/4πd 2 where d is the diameter, we have Area = 1/4πd 2 = 1/4 x 3.14 x 10 2 = 78.54 What is the radius of a circle with a 10-inch diameter? The radius of a 10-inch circle is 5 inches because the radius is half of the diameter of a circle.
Find the surface area of the composite solid.
Answers
Answer:
281 ft^2
Step-by-step explanation:
We need to add each individual 2d shape together to find the surface area
Bottom: 5*12 = 60
Left side and right side: 4*5 = 20, 2 sides so 20*2= 40
Side facing us and side facing away from us: 12*4 = 48, 2 sides so 48*2=96
Top side that is cut by base of triangle: 7*5 = 35
Each triangle face: base = 5 (12-7), height = 5 1/2base * height so each triangle is .5*5*5 = 12.5; 4 triangles so 12.5*4=50
60+40+96+35+50=281

Freddy reads an equal number of pages of a book every week. The graph below shows the number of pages of the book left to read, y, after x weeks:
A graph titled Freddy’s Book Reading shows Number of Weeks on the x-axis and Number of Pages Left on the y-axis. The scale on the x-axis shows numbers from 0 to 6 at increments of 1, and the scale on the y-axis shows numbers from 0 to 280 at increments of 40. A straight line joins the ordered pairs 0, 200 and 1, 160 and 2, 120 and 3, 80 and 4, 40 and 5, 0.

the plus 6 and minus 6 cancel each other out and make the same area that the square has.

Step-by-step explanation:
The Mean Absolute Deviation (MAD) is the average amount that each point is from the overall average of the data set.
So, first find the overall average (also called the mean):
avg = (1 + 1 + 2 + 3 + 5 + 7 + 9) / 7
= 28 / 7
= 4
The average (mean) is 4, so now you calculate how far each point is from 4 and average those numbers:
Note: Remember to use absolute values, since distance can't be negative.
4 - 1 = 3
4 - 1 = 3
4 - 2 = 2
4 - 3 = 1
4 - 5 = |-1| = 1
4 - 7 = |-3| = 3
4 - 9 = |-5| = 5
And finally, average (or find the mean) the new data set:
avg = (1 + 1 + 2 + 3 + 3 + 3 + 5) / 7
so 18 / 7 is the MAD of the data set.
Finally, round it to the nearest tenth:
18 ÷ 7 = 2.57142857143 ≈ 2.6

A new club sent out 294 coupons to boost sales for next year's memberships. They provided 6 times as many to potential members than to existing members. How many coupons did they send to existing members?
Answers
Answer:
42
Step-by-step explanation:
6 times as many means that they sent out 6 to 1. Anytime I see x times as many i always add 1. The formula for this would be x+1. x=6 6+1=7. There were 294 coupons sent out so 294/7=42. 42 equals the amount of existing members there are. I hope you understand.

D. There is no solution
Step-by-step explanation:
The slope-intercept formula is y = mx + b
The mx stands for the slope, and the b stands for the y-intercept.
y > 1/3x + 5
Since you're talking about y, think in terms of up and down!
The > means anything that is above the line should be shaded. (Because it's greater than)
y < 1/3x - 1
The < means anything that is below the line should be shaded. (Because it is less than)
All the graphs shown have the same lines plotted, so pay attention to the shading.
For y > 1/3x + 5, look for shading above the line with a y-intercept at 5.
For y < 1/3x - 1, look for shading below the line with a y-intercept at -1.

A school class went on a field trip to see a magician perform there were 17 females 20 males in the class the magicians randomly selected a volunteer from the audience in which had 52 females and 68 males given that the randomly selected audience member is a student from the class which equation can be used to find the probability p that the person also a female?
( I'll give brainly to whoever answers it correctly )
Answers
Answer:
P(B)= 17/20
Step-by-step explanation:
The audience of the magic show is conformed by a total of 120 people, 52 of which are female and 68 are men.
Within the audience there is a school class of 37, of these students, 17 are female and 20 are male.
If a random member of the audience is selected as a volunteer:
Let "A" represent the event that "the selected volunteer is a student of the class"
And "B" the event that "the selected student is female"
You have to calculate the probability of the selected volunteer being female, given that it is a member of the school class.
Symbolically:
P(B|A)
Using the formula of conditional probabilities you can calculate it as:
P(A∩B)= =
As you can see the probability of the event "The volunteer is female given that it was a student of the school class" means that you already know the selected volunteer was a student and only needed to calculate the probability of that student being female.
P(B)= 17/20
I hope this helps
