Answer: n=-5
Step-by-step explanation:
distribute: 0.6(10n+25)=10+5n 0.6(10n)= 6n 0.6(25)=15 so then you put the problem together again... 6n+15=10+5n then you cancel out the n variable... 10-15=-5 6n=-5+5n 6n-5n=1n 1n=-5 -5/1 n=-5

Given the following list of data, find the median. 3,18,11,36,23,5,8,15,32,22,16 Give your answer as a number only. For example, if you found the median was 20, you would enter 20.
Answer:
The median is 16.
Step-by-step explanation:
To find the median of a set, first we sort the set in an incresing way. So
3,5,8,11,15,16,18,22,23,32,36
The set has 11 elements, so the median will be element at the position (11+1)/2 = 6, that is, the 6th element of the sorted set.
In this case, the median is 16.

Malik completes 0.7 of the total number of push-ups his coach requires. Which does NOT represent the part of the push-ups Malik completes? Please help I really need your help!!!
7%
14/20
70%
0.70
Answer:
7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.
Step-by-step explanation:
Given that Malik completes 0.7 of the total number of push-ups his coach requires.
Checking the given options:
7% = 7/100 = 0.07
14/20 = 0.7
70% = 70/100 = 7/10 = 0.7
0.70 = 0.7
Therefore,
7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.

1. The height of a soccer ball that is kicked from the ground can be approximated by the function:
y= -18x^2 + 90x
where y is the height of the soccer ball is x seconds after it is kicked.
Find the time, in seconds, it takes from the moment the soccer ball is kicked until it returns to the ground.
2. The height of a soccer ball that is kicked from the ground can be approximated by the function:
y = -16x^2 + 64x
where y is the height of the soccer ball in feet x seconds after it is kicked. What is the soccer ball's maximum height in feet?
Answer:
2. [tex]\displaystyle 64\:feet[/tex]
1. [tex]\displaystyle 5\:seconds[/tex]
Step-by-step explanation:
2. Sinse we do not have a y-intercept [C-value in this case], we have to use a part of the quadratic formula to solve for x, and rewrite this equation in Vertex Form, with [tex]\displaystyle [h, k][/tex] as the vertex point. Observe:
[tex]\displaystyle -\frac{b}{2a} = x \\ \\ -\frac{64}{2[-16]} = \frac{-64}{-32} = 2[/tex]
Now, keep in mind that [tex]\displaystyle -h[/tex] in the vertex formula, [tex]\displaystyle y = a[x - h]^2 + k,[/tex] gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so in this case, sinse 2 is already positive, you do not need to alter its operation sign. With this being stated, you should already have this:
[tex]\displaystyle y = -16[x - 2]^2[/tex]
Now, to find k, all you have to do is plug 2 into the TOP equation to get your maximum height:
[tex]\displaystyle -16[2]^2 + 64[2] = -16[4] + 128 = -64 + 128 = 64 \\ \\ \\ y = -16[x - 2]^2 + 64[/tex]
Therefore, sinse 64 is your k-value, 64 feet is indeed your maximum height.
1. Simply factour the quadratic equation:
[tex]\displaystyle y = -18x^2 + 90x \\ 0 = -18x[x - 5] \\ \\ 5, 0 = x[/tex]
In this case, from a height of sixty-four feet, it is IMPOSSIBLE for the football to hit the ground in zero seconds, therefore the ball will reach the ground in 5 seconds, which makes alot more sence.
I am joyous to assist you at any time.
** Minimum Height → [tex]\displaystyle A[/tex]
** Maximum Height → [tex]\displaystyle -A[/tex]

Clarissa has a bag of marbles. 9 are blue, 5 dre yellow, 2 dre purple, and 4 are green. What is the probability Clarissa reaches in the bag and pulls out a yellow marble, and then without replacing it, pulls out a marble that is not blue?
Answer:
Step-by-step explanation:
So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.
5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%
Then, lets do just finding the probability of a color that isn't blue.
Out of 20 marbles, 11 are color not blue, and 9 are.
So that probability is 11/20
Now, I think we need to do 11/20-5/20 so 6/20=3/10
Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.
Simplify the expression using distributive property

Which we can write as
-6x-18
Answer:
[tex]\huge\boxed{\boxed{{\boxed{{-6x-18}}}}}[/tex]
Step-by-step explanation:
Hello.
In order to simplify the expression, we should multiply -3 times 2x and 6:
-3 times 2x = -6x
-3 times 6=-18
-6x-18
And we're done!

The graph shows y as a function of x:
In which segment is the function constant?
О А
O B
О C
O D
Answer:
A
Step-by-step explanation:
A constant line looks like a flat line with a slope of 0.
The segment that shows a constant function is segment A.
Option A is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,A function is constant if the graph is a straight line.
So,
From the given graph, we see that line A is a straight line.
This means,
Segment A shows a constant function.
Thus,
The segment that shows a constant function is segment A.

kareem is paid 72 for working 8 hours how much would he have been paid to work only 5 hours
Answer:
If Kareem were to work for 5 hours, she would get paid $45.
Step-by-step explanation:
If she gets paid $72 for working 8 hours, you would need to find how much she gets paid per hour by doing [tex]72/8[/tex].
Which then gives you $9 per hour, so then all you need to do is multiply $9 by the number of hours which in this case is 5 to get the answer of $45.

The 150 students in the band will attend an awards assembly. A random survey of 30 was done to see what type of pizza they would order. 10 Pepperoni 15 Cheese • 5 Hamburger Based on the survey results, which of these is the best prediction of the types of pizza wanted by the 150 students? A. There are 40 students who want pepperoni B. There are 100 students who want either pepperoni or hamburger C. There are 10 more students who will want cheese than hamburger D. There are 5 more students would want pepperoni than hamburger (PLEASE ANSWER ILL GIVE BRAINLIEST)
Answer:
None are correct.
Step-by-step explanation:
10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.
15/30 wanted cheese, so 1/2 wanted cheese.
5/30 wanted hamburgers, so 1/6 wanted hamburgers.
You can use this information to estimate the number of the 150 students who wanted each.
1/3 of 150 = an estimated 50 wants pepperoni
1/2 of 150 = an estimated 75 wants cheese
1/6 of 150 = an estimated 25 wants hamburgers
Now you can use this to see which one is true.
A. There are 40 students who want pepperoni
not true, there are 50
B. There are 100 students who want either pepperoni or hamburger
50(pepperoni) + 25(hamburger) = 75, so this is not true
C. There are 10 more students who will want cheese than hamburger
75(cheese) - 25 (hamburger) = 50, so this is not true.
D. There are 5 more students would want pepperoni than hamburger
50 (pepperoni) - 25 (hamburger) = 25, so this is not true
None of these answers are correct
