Middletown sponsors a two day conference for selected middle school students to study government. Suppose 20 student delegates will the attend the conference Each school should be represented fairly in relation to it's population.
Answers
Answer:
North Middle School = 10 students Central Middle School = 6 students South Middle School = 4 studentsStep-by-step explanation:
First calculate the total number of students in all the schools:
= 618 + 378 + 204
= 1,200 students
Use this number to calculate the proportion of the total population that a school so that this can then be used to determine the proportion of the 20 delegates they should sent.
North Middle school:
= 618/1,200 * 20
= 10 students
Central Middle School:
= 378 / 1,200 * 20
= 6 students
South Middle School:
= 204/1,200 * 20
= 4 students

Answer:
1. 8x + 3y - x - 2y
= 8x - x + 3y - 2y
= 7x + y
2. 3n - 7n - 2n + x + 8x
= 3n - 9n + 9x
= - 6n + 9x
3. 2r - 5n + 9y - 3r + n
= 2r - 3r - 5n + n + 9y
= -r - 4n + 9y
4. 12y - 6x + 5y - 3n
= 12y + 5y - 6x - 3n
= 17y - 9n
5. - 13n + 4n - r
= -9n - r
6. 7xy - 8x + 6xy - y
= 7xy + 6xy - 8x - y
= 13xy - 8x - y
7. - 14r - 10n - 3r - 9n
= -14r - 3r - 10n - 9n
= - 17r - 19n
8. 6r + 9r - 2r - 13n
= 6r + 7r - 13n
= 13r - 13n
9. n + r + x - 3x +4r
= n + r + 4r + x - 3x
= n + 5r - 2x
10. 15y - 7x + 9z + 4z - 3x
= 15y - 7x - 3x + 9z + 4z
= 15y - 10x + 13z

Answers
Let's put it in the second equation
3/4x-3=1/4x+1
3/4 x -1/4 x = 1+3
2/4 x = 4
X= 4*4/2
x=8
Put x= 8 in first equation
y= 3/4 *8 -3
y=6-3
y=3
Check the answer
3=3/4 *8 -3
3=6-3
3=3
Correct
So(y, x) = (3,8)
Because x=8 and y=3

Step-by-step explanation:
a) Any set of functions that has a total degree of 4 and a total number of x-intercepts of 4 will do. Shown in the first attachment are 4 linear functions. A quadratic function with two x-intercepts could replace two of the linear functions, or a cubic with 3 x-intercepts could replace 3 of the linear functions.

b) Again, the total degree must be 3. Since there can only be one x-intercept, the quadratic factor must have none. A possible choice is shown in the second attachment.

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will it takes the plant to reach one foot.
Answers
Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks

Trail Mix Ingredients 4 cup almonds 4 cup pumpkin seeds 4cup coconut 4cup dried cranberries 1 4cup walnuts 1 cup granola4cup dried bananas
Answers
Answer:
The values written as Trail mix ingredients is not well written below is the trail mix ingredients
answer :
i) Ian made : 1 3/4 cups of trail mix
ii) Racheal made 1/4 more cup of trail mix
Step-by-step explanation:
Given that :
Trail Mix Ingredients
3 /4 cup almonds
1 /4 cup pumpkin seeds
2 /4 cup coconut
3 /4 cup dried cranberries
1 2 /4 cup walnuts
1 cup granola
2 /4 cup dried bananas
i) Ian used all of coconut , dried cranberries and dried Bananas
= 2/4 + 3/4 + 2/4
Amount of trail mix made = 7/4 = 1 3/4 cups
ii) Racheal made 2 cups of trail mix containing ; all almonds , pumpkin seeds and granola
= 3/4 + 1/4 + 1 = 2 cups of trail mix
Hence Racheal made ( 2 - 1 3/4 ) more trail mix than Ian
= 1/4 more cup of trail mix was made by Racheal
An online games club charges $5.75 for the first game download and $2 for each additional
download per month. Write a rule for describing the total monthly fees f as a function of
additional downloaus d. What are the fees for 15 game downloads in a month?
Answers
Answer:
a) The rule is;
f = 5.75 + 2d
b) f = $33.75
Step-by-step explanation:
Here, we want to write a rule
The rule is that we have a standard download fee of 5.75 for the first download, and then a download fee of $2 per download for the rest
We have this as;
f = 5.75 + 2(d)
f = 2d + 5.75
Now for 15 downloads;
first download is $5.75, remaking 14 is at a rate of $2 per one
Thus, we have the fee value as;
f = 5.75 + 2(14)
f = 5.75 + 28 = $33.75

Answers
Answer:
x = 5, y = 17, z = 8
Step-by-step explanation:
Since the triangles are congruent to each other, corresponding angles and sides are congruent to each other.
JL corresponds with QS so...
3x - 1 = 14
3x = 15
x = 5
RS corresponds with LK so...
y + 10 = 27
y = 17
Angle L corresponds with angle S so...
180 - 58 - 87 = 4z + 3
35 = 4z + 3
