Answer:
Finding Rate of Change. When finding the slope of real-world situations, it is often referred to as rate of change. “Rate of change” means the same as “slope.” If you are asked to find the rate of change, use the slope formula or make a slope triangle.
Step-by-step explanation:
The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth graders. If 4/5 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answer:
584 is the total number of students in the school.
5/8 are in seventh grade and 3/8 are in eighth grade.
4/5 of the seventh graders participated in the track meet, so there were (4/5 · 5/8) · 584 students in the seventh grade participating in the track meet.
7/8 of the eighth graders participated, so there were (7/8 · 3/8) · 584 students in the eighth grade participating in the track meet.
So, all together, there were
(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 students from the school in the track meet.
Let's simplify as you asked:
(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 = [(4/5 · 5/8) + (7/8 · 3/8)] · 584 (distributive property - factoring)
= [20/40 + 21/64] · 584 (multiply fractions)
= (1/2 + 21/64) 584 (reduce the first fraction to lowest terms)
= (32/64 + 21/64) 584 (getting a common denominator)
= (53/64) 584 (combine/add the two fractions)
= 483.625 (multiply together)
All together, there were: 483.625 students in the meet.

Read the excerpts from Team Moon and the NASA article.
And only now—a solid, panic-stricken, gut-wrenching, heart-palpitating ten minutes by clock but feeling like an eternity later—did it sink in for John Coursen, Tom Kelly, and a lot of the other Grumman folks who had poured years of their lives into building the lunar module: Their baby was on the moon. Let the cheering begin!
When the lunar module lands at 4:18 p.m. EDT, only 30 seconds of fuel remain. Armstrong radios "Houston, Tranquility Base here. The Eagle has landed." Mission control erupts in celebration as the tension breaks, and a controller tells the crew "You got a bunch of guys about to turn blue, we're breathing again."
How is the information in the excerpts different?
A. The first excerpt is less emotional than the second excerpt.
B. The first excerpt is less interesting than the second excerpt.
C. The first excerpt is more emotional than the second excerpt.
D. The first excerpt is more interesting than the second excerpt.

A florist had 88 flowers. She wanted to put
them into 42 bouquets with the same number of
flowers in each. How many flowers will she get to put
into each bouquet? How many will be left?
or *
Answer:
2 (Remainder 4) In decimal form to the hundredths: 2.09
Step-by-step explanation:
42 can only go into 88 two times, so 42 x 2 = 84. So then 2 is your answer. BUT you have 4 left, so it's 2 remainder 4. If you want to round to the tenths, hundredths, ect, here is the original decimated number: 2.09523809524Here is the real problem ! Giving 30 points!

An amusement park had 250 people attend during the course of 7 hours. At this rate, how many would they expect to attend over 15 hours?
Answer:
536 people
Step-by-step explanation:
What I did was I divided 250 by 7 which gives the average hour of people which is=36 people per hour
Then you multiply 35.7 by 15 which gives you=536 people at the amusement park in 15 hours.

Saba and Hena saved up Rs. 81.75 and Rs 45.25 respectively to buy a gift for
Mother’s Day. How much money in all have the sisters set aside for the gift?
Answer: $127.00
Step-by-step explanation:
Step 1: Line 81.75 + 45.25 up with 81.75 on top and 45.25 underneath.
Step 2: add the two 5’s (making 10) put the 0 underneath that and carry the one over to the left. ( 7+2+1 =10) then put your decimal point after the zero. repeat process (5+1+1=7) than add up 8+4 =12

∠A and ∠B are vertical angles. ∠B is supplementary to ∠C. If ∠C measures 42°, how large is ∠A?
Answer:
138 degrees
Step-by-step explanation:
Since angles B and C are supplementary, that would mean they add up to 180. The problem tells us that angle C is 42 degrees, so that would mean that angle B is 138 degrees. We are also told that angles A and B are vertical, which would mean that they are congruent to each other. That leaves us with the answer that angle A is 138 degrees.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)
Answer:
(0,0) and (3,12)
Step-by-step explanation:
The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).
As shown in the graph,
x-axis represents the number of years
y-axis represents the number of puppies.
The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.
The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.
The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.
For example, in the case of (2, 6), the number of puppies should be 8, not 6.
Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).

Okay so the 4(2t +2) and 4t + 8 + 4t go under 8t + 8, because when you distribute and add like terms, you get 8t+ 8 for both
(8*t)+(8*8) and 8t + 64 go under 8(t+8) because similar to the other, when you distribute and add like terms you get 8(t+8) for both
The last two options 8t+16 and (8+t) +(8+8) go under neither because when distributed and added, they don't match up to either or

PLEASE HELP ME MY BRAIN CAN'T TAKE IT: Lin’s family has completed 70% of a trip. They have traveled 35 miles. How far is the trip in miles?
Answer:
Okay so, 70% of a trip.
Divided 35 by 7, and you get 5. Therefore I think 5 miles is 10% of the trip. So, the entire trip would be 50 miles. SORRY IF THIS IS WRONG

Which statements accurately describe how to determine the y-intercept and the slope from the graph below?
On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.

Answer:
summary
Step-by-step explanation:
Answer: Choice C
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)
============================================
Explanation:
The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.
The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,
slope = rise/run = (change in y)/(change in x)
Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.
