Step 2: Find Value

[Rational Expression] Substitute in x:

[tex]\displaystyle\begin{aligned}\frac{x}{x^2 - 9} ,\ x = -3 & \rightarrow \frac{-3}{(-3)^2 - 9} \\& \rightarrow \frac{-3}{0}\end{aligned}[/tex]

∴ since we can't divide by 0, our rational expression when x = -3 will have to be undefined.

6x - 4= -4(X-5)
What value of x makes the equation true?

Answers

Answer:

Step-by-step explanation:

Equation 6x - 4= -4(X-5)                      Remove the brackets

Solution

6x - 4 = -4x + 20                                   Add 4x to both sides

6x + 4x -4 = -4x+4x + 20                      Combine

10x - 4 = 20                                           Add 4 to both sides

10x - 4 + 4 = 20 + 4                               Combine

10x = 24                                                 Divide by 10

10x/10 = 24/10

-. The side views of two different ramps are shown below. Which is a true
tatement about the slope of the ramps?

Answers

The statement that is true about the slope of the ramps is: A. Slope of ramp A = slope of ramp B.

What is the Slope?

Slope = gradient = rise / run = vertical distance / horizontal distance.

Slope of the side view of ramp A = rise / run = 20 / 30 = 2/3.

Slope of  the side view of ramp B = rise / run = 14 / 21 = 2/3.

The slope of A = slope of B = 2/3

The statement that is true of the slopes of both ramps is therefore: A. Slope of ramp A = slope of ramp B.

find the prime factorization of the following number 252?​

Answers

Answer:

2,3,7 are the prime factorization of number of 252

Hi Student!

Prime factorization is the process of stripping down a number to it's basic elements.  We take a number and bring it down the most we can.  For example we take 4 and make it 2 x 2.  In this case we are given a number of 252 so we can began by dividing by 2.

[tex]252 / 2[/tex]

[tex]126[/tex]

Looking at the numbers that we have now, 126 x 2, we can see that 126 can still be divisible by another 2 so lets do that again.

[tex]126 / 2[/tex]

[tex]63[/tex]

Now, looking at the numbers that we have, 63 x 2 x 2, we see that we can no longer divide it by a 2 because 63 is not divisible by 2.  However, we can divide 3 away from the number so lets do that.

[tex]63 / 3[/tex]

[tex]21[/tex]

Once again, looking at the numbers that we have, 21 x 3 x 2 x 2, we see that we can once again divide a 3 away from our first number so lets do that again.

[tex]21 / 3[/tex]

[tex]7[/tex]

Finally, we have come down to the last line where our final elements are 7 x 3 x 3 x 2 x 2.  This is our prime factorization of the number 252 and this is where we can conclude our solution seeking.

34% of the 6th graders and 50% of the 7th graders want to go to the water slides. What percentage of the 8th graders want to go to the water slides?

Answers

The percentage of the 8th graders to want to go to the water slides will be 70.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.

The percentage of the 8th graders want to go to the water slides is found from;

[tex]\% (8 ^{th} grade)= 0.46-(0.5 \times 34 \%+0.3 \times 50\%_)\\\\ \% (8 ^{th} grade)=0.46-(0.17+0.15)\\\\ \% (8 ^{th} grade)=0.14\\\\ \% (8 ^{th} grade)= \frac{0.14}{0.20} \\\\ \% (8 ^{th} grade)=70\%[/tex]

A submarine begins 300 feet below sea level. It makes four moves of 30 feet each
toward the surface. How many more feet does the submarine need to move to reach
the surface?

Answers

Answer:

180 feet

Step-by-step explanation:

Starting number is 300.  Four moves of 30 feet is 120 feet.

30x4 = 120

300-120 = 180

Answer:

180 feet.

Step-by-step explanation:

Remark

You need some formal way of expressing what is happening. You start at 300 feet below sea level, and make make 4 moves of 30 feet each. Where are you and how much further do you have to go to reach the surface?

Equation

Distance to go = distance in feet below sea level - number of moves *  feet / move.

Givens.

original distance below sea level = 300 feet.

number of moves = 4

distance towards the surface for each move = 30  feet.

Distance to go. = ?

Solution

Distance to go = 300  - 4*30

Distance to go = 300 - 120

Distance to go = 180 feet

Answers

Answer: Option (c) is correct.

68% of the data points lie between 10 and 18.

Step-by-step explanation: Given :  a normal distribution with a standard deviation of 4 and a mean of 14

We have to choose the  sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.

Since, given 68% data.

We know mean of data lies in middle.

And standard deviation is distribute equally about the mean that is 50% of values less than the mean  and 50% greater than the mean.

So, 68% of data lies

mean - standard deviation = 14 - 4 = 10

mean + standard deviation = 14 + 4 = 18

So, 68% of the data points lie between 10 and 18.

Given: AC = 4x-29
A 19 B 2x-18
X=
AC =
BC=
C

Answers

Answer:

x = 15
AC = 31
BC = 12

Explanation:

To setup the equation it is:

2x + 1 = 4x - 29

Because AC is the whole thing.
Meaning AB + BC = AC.

1 = 2x - 29
30 = 2x
30/2 = 15

15 = x

4(15) - 29 = 31
31 = AC

2(15) - 18
12 = BC

We know that Angles subtended by the very same arc at any position on the circular path are half of the angles subtended by the very same arc at the centre.

Then we have

2∠ABC = ∠AOB

2∠ABC = 80°

 ∠ABC = 40°
