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.

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.

find the quadrant ;)
Answer:
The area is 15 units and it is in quadrant I and II
Step-by-step explanation:
Area = 1/2length x height
= 1/2(6) x 5
=3 x 5
=15
The quadrants go top left = I, top right = II, bottom left = III, and bottom right = IV

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.

5b. 2.8
5c. 13^2-5^2=b^2
5d.12
Step-by-step explanation:
All are based on a^2+b^2=c^2
2^2=4. 4+4=8 The square root of 8 is 2.8
You work backwards with the other one. 5^2+b^2=13^2

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.
