Answer:

Step-by-step explanation:

6x + 9 = 57

6x = 57 - 9

6x = 48

x = 48/6

x = 8

no...I dont agree with Amanda.

I arrived at x = 8.....and this can be confirmed by subbing in 8 for x back into the original equation.

6x + 9 = 57......x = 8

6(8) + 9 = 57

48 + 9 = 57

57 = 57 (correct)

Help !! Pleaseeeeeeeee
marysya [2.9K]

Answer:

Step-by-step explanation:

arc BE is the same as the interior angle, or 76°

BE = 76 °

we can also find arc CE the same way,  b/c we can see that the interior angle is the suppment with 76  or   180-76 = CE  or 104°

Now we know all the arcs but arc CD

so use the idea that all the way around the circle is 360°

360 = 76 + 104 + 140 + CD

360 - 76 - 104 - 140 = CD

40 = CD

CD = 40 °

If f(x)=5x^2 and g(x)=x-2 what is (fog)(-3)
olga2289 [7]

Answer:

(fog)(-3) = 125

Step-by-step explanation:

So, we need to first evaluate g(-3) and then plug the value of g(-3) into f(x) to find (fog)(-3). So, let's do that:

g(-3) = -3-2 = -5

f(g(-3)) = f(-5) = 5(-5)^2 = 5(25) = 125

Thus, (fog)(-3) = 125.

Open-Ended Question<br>*Picture*
My name is Ann [436]
We have to calculate the volume of the right rectangular prism.
lenght=4 1/2 in=(4+1/2) in=9/2 in
width=5 in
height=3 3/4 in=(3+3/4) in=15/4 in

Volume (right rectangular prism = lenght x width x height.
volume=9/2 in * 5 in * 15/4 in=675/8 in³

we calculate the volume of this little cube.
volume=side³
volume=(1/4 in )³=1/64 in³

Now, we calculate the number of small cubes are needed to fit the right rectangular pris by the rule of three.

1 small cube----------------1/64 in³
x---------------------------------675/8 in³

x=(1 small cube * 675/8 in³) / 1/64 in³=5400 small cubes.

Answer: we need 5400 small cubes to fit the right rectangular prism.

Forty students took a statistics exam having a maximum of 50 points. The distribution of score is given in the stem-and-leaf plo
Aneli [31]

Based on the fact that Tess's score was 25 in the statistics exam as shown by the stem-and-leaf plot, her Tess's percentile was 30th.

<h3>What was Tess's percentile?</h3>

Tess's percentile depends on the number of people whose scores she is above.

When looking at the stem-and-leaf plot, we see that Tess's score of 25 is the 13th score.

Her percentile is therefore:

= (13 - 1) / 40

= 12 / 40

= 30th percentile

Rest of the question is:

Tess’s score was 25. What was her percentile?
