Answer:
The number of 7th graders exceed that of the number of 5th and 6th graders taken together by 5.88%.
Step-by-step explanation:
I am going to say that:
x is the proportion of 5th graders.
y is the proportion of 6th graders.
z is the proportion of 7th graders.
The number of 6th graders in RSM summer camp to that of 7th graders was 4 to 11
This means that:
\frac{y}{z} = \frac{4}{11}
z
y
=
11
4
So
11y = 4z11y=4z
y = \frac{4z}{11}y=
11
4z
The number of 5th graders to that of the 6th graders was 13 to 9.
This means that:
\frac{x}{y} = \frac{13}{9}
y
x
=
9
13
9x = 13y9x=13y
x = \frac{13y}{9}x=
9
13y
All of them is 100%
This means that:
x + y + z = 1x+y+z=1
We need to find z.
y = \frac{4z}{11}y=
11
4z
x = \frac{13y}{9} = \frac{13*4z}{9*11} = \frac{52z}{99}x=
9
13y
=
9∗11
13∗4z
=
99
52z
Then
x + y + z = 1x+y+z=1
\frac{52z}{99} + \frac{4z}{11} + z = 1
99
52z
+
11
4z
+z=1
The lcm(least common multiple) between 11 and 99 is 99. Then
\frac{52z + 9*4z + 99z}{99} = 1
99
52z+9∗4z+99z
=1
187z = 99187z=99
z = \frac{99}{187}z=
187
99
z = 0.5294z=0.5294
By what percent did the number of 7th graders exceed that of the number of 5th and 6th graders taken together ?
z(7th graders) is 52.94%.
x + y(5th and 6th graders) is 100 - 52.94 = 47.06%
52.94 - 47.06 = 5.88
The number of 7th graders exceed that of the number of 5th and 6th graders taken together by 5.88%.

D. Tel along the x-axis, and two along the y-axis
The variables displayed in a scatter plot are: (a) one along the x-axis, and one along the y-axis
The variables of a scatter plot are the quantities whose correlation is being determined
In a scatter plot, they are always two variables.
One is placed on the x-axis, while the other is on the y-axis
Hence, the variables displayed in a scatter plot are: (a) one along the x-axis, and one along the y-axis

Identify the slope and y-intercept of the graph y = -1/3x + 6.
2. slope = 6, y-intercept = -1/3
1. slope = -1/3, y-intercept = 6
Answer:
A.slope = 6, y-intercept = -1/3
Step-by-step explanation:
Y = 4x + 9
What is the slope and the y-intercept?
Answer:
y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9
Answer:
m = 4b = 9Step-by-step explanation:
We know that:
y = mx + by = 4x + 9If we compare these two equations, we can find the slope and the y-intercept.
=> (y = mx + b) = (y = 4x + 9)
We can clearly see that 'm = 4' and 'b = 9'.
Conclusion:
Therefore:
m = 4b = 9Hoped this helped.
A. Are the expressions 3(m−2) + 2(m−2) and 5(m−2) equivalent expressions?
B. In two or more complete sentences, justify your answer to A.
Answer: yes, this is because when you solve the first equation then your answer will be 5(m-2). You do this by distributing 3 to m & 2 (multiply), then you will distribute 2 to m & 2 (also multiply).

A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in 1 over 5 of a minute. Don calculated the unit rate to be 3 over 20 of a gallon per minute. What did he do wrong?
Answer:
First, you have to see how many gallons fill in a minute, obviously, so take 3/4 and divide it by 1/5, which gives 15/4. so you can see, don multiplied the two numbers instead of dividing, which is what he did wrong.Step-by-step explanation:
Answer from NukeExplosions1
Answer:
What he did wrong is that he multiplied the denominator wrong. it is supposed to be a 15. Don should re-calculate it to 3 over 15 of a gallon per minute.

No links or unreasonable random answers. Thank you.
Step-by-step explanation:
A better way to word this is how much more is 4/9 than 2/9 which is 2/9 more because 2/9 plus 2/9 is 4/9 and the denominator stays the same

which is shorter 8ft or 95in !?
Answer: 95 in is shorter
Step-by-step explanation:
there are 12 in in a foot, so in that case you have to divide 95 in by 12. The answer is 7.91666667 but if you round it up you would get 8, which that is = 8ft but without rounding it up you would get 7.9ft which is less than 8ft. so the answer is 95 in is shorter than 8ft
A number line going from 0 to 1. There are 6 equal spaces between 0 and 1. The line contains 0, A, B, blank, C, D, 1.
What fraction is represented by Point A?
Point A is at
.
Which point represents 5
6
?
Point
represents 5
6
.
Answer:
The number line is divided by 6ths.
Step-by-step explanation:
There are 6 equally sized spaces between 0 and 1 on a number line. By definition of a fraction, a quantity is divided upon a number of equal parts in which can be expressed as the number of parts divided by the total number of parts. Therefore, the numerator in this case will be how many of the 6 parts are there at a certain point; the denominator will be 6, since there are 6 total, equal parts. In this case, think of the fraction as a distance traveled from 0 to 1 in 6 parts; the numerator is how far is traveled, and the denominator is the total travel distance. Point A is located at 1/6, since it is 1 out of the 6 pieces traveled. Point D would be at 5/6 because it has traveled 5 out of the 6 distances.
Point A is at
✔ 1/6
Point
✔ D
