Explanation:

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%.

The distance if you look at the graph has started on 20 so that will be it when they drive

First, let's do the numerator! 4.8 - 0.24 = 4.56. Now, let's simplify the denominator. 0.2 * 0.6 = 0.12

4.56 / 0.12 = 38

Hope this helps :)

Answer: 1

Step-by-step explanation: 1 is the greatest common factor of 70 and 33.

Step by step solution :Step  1  :Equation at the end of step  1  : (((3•(x2))•(y4))3) 4•—————————————————— ((2x3•(y5))4) Step  2  :Equation at the end of step  2  : ((3x2 • (y4))3) 4 • ——————————————— 24x12y20 Step  3  : 33x6y12 Simplify ———————— 24x12y20 Dividing exponential expressions :

3.1    x6 divided by x12 = x(6 - 12) = x(-6) = 1/x6

Dividing exponential expressions :

3.2    y12 divided by y20 = y(12 - 20) = y(-8) = 1/y8

Equation at the end of step  3  : 27 4 • —————— 16x6y8 Step  4  :Final result : 27 ————— 4x6y8

The simplified expression is [tex]27/(16x^6y^8).[/tex]

We have,

To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.

Let's simplify the numerator first:

[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]

Now, let's simplify the denominator:

[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]

Now we can divide the numerator by the denominator:

[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]

To divide the variables with the same base, we subtract their exponents:

[tex]27/16 * x^{6-12} * y^{12-20}[/tex]

Simplifying further:

[tex]27/16 * x^{-6} * y^{-8}[/tex]

To make the exponents positive, we can move the variables with negative exponents to the denominator:

[tex]27/(16x^6y^8)[/tex]

Therefore,

The simplified expression is [tex]27/(16x^6y^8).[/tex]

Answer:

Green is with C, Blue is with A, Orange is with D, Purple is with B

Step-by-step explanation:

Hi!

So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)

(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)

1(left)-7/1/4 is the same as 7/ .25. This is 28.

2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating

3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating

4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)

1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.

2(right) 1/4 x 7 is the same as .25*7. This is 1.75

3(right) 7*4 is 28.

4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533

Now, we can match.

Green is with C.

Blue is with A

Orange is with D

Purple is with B
