H. 33
Answers
Answer:
G.31
Step-by-step explanation:
when n = 31
1116n = 1116*31 = 34596
34596 is square of 186.
= 186^2
= 34596
and other values (24,28,33) of n does not give square during 1,116n but 31 gives.
Hence, 31 is the possible value of n for which 1,116n is the square of an integer(186).

KM = 7

KL = 11
Step-by-step explanation:
Isosceles triangles have 2 congruent sides (in this case they are KM and LM
This means 4d-13 = 12-d
We can now solve for d
4d-13 = 12-d | add d to both sides
5d-13 = 12 | add 13 to both sides
5d = 25 | divide both sides by 5
d = 5

There are 9 marbles all together.
2 are green4 are red3 are blueThe important fact is that he draws 1 marble to begin with and does not replace it. That means that the next marble is out of 8.
Solution
First marble: Blue = 3/9 = 1/3
Second marble: Green 2/8 = 1/4
The probability of that happening is
P(blue,Green) = 1/3 * 1/4 = 1/12

Answers
Answer:
Step-by-step explanation:
Formula
d = speed * time
d = s * t
Givens
t = 1 hour
t2 = 3 hours
s = 5 miles / hour
Solution
t = 1 hour
d = s * t
d = 5 mph * 1 hour
d = 5 miles
t = 3 hours
d = s * t
d = 5 miles / hour * 3 hours
d = 15 miles
Answer
d = s * t
d = 5 miles
d = 15 miles

Hello student!
We are given two angles that are right next to each other and are formed off of a 180 degree angle. These two angles are known as supplementary angles which means that the two angles add up to 180 degrees. Using that information we can create an equation to help us find x.
[tex]Angle_1 + Angle_2 = 180[/tex]
[tex](5x - 18) + (4x + 45) = 180[/tex]
We now have a functioning equation which we can use to determine x. The first step that we have is to combine like terms which means to add together numbers which the same variables. In this case 5x and 4x would add together and -18 and 45 would also add together.
[tex](5x - 18) + (4x + 45) = 180[/tex]
[tex](5x + 4x) + (-18 + 45) = 180[/tex]
[tex]9x + 27 = 180[/tex]
Now we are down to the final steps which is just some algebra. The first step that we need to do is subtract 27 from both sides which will remove the excess numbers from the left side.
[tex]9x + 27 - 27= 180- 27[/tex]
[tex]9x = 153[/tex]
The second step that we will need to do is divide both sides by 9 which will help us isolate x and give us our final answer.
[tex]\frac{9x}{9} = \frac{153}{9}[/tex]
[tex]x=17[/tex]
Therefore, our final answer is that x is equal to 17.

The time he spent on homework each night. this box plot shows the results.
The time spent on homework (min.) 20 40 60 80 100 120.
The percentage will be calculated as:-
Maximum time spent = 120 minutes
The percentage for 80 minutes of homework will be:-
= 120 / 80
= 0.66=66 = 66.66%
Therefore the percentage of time spend at least 80 minutes on homework will be 66.66%.

Answers
The median, mode and range of the numbers are 9, 5 and 7 respectively.
How to find median, range and mode?
The median is the middle number when the data is arranged in ascending order.
Therefore,
7, 7, 7, 8, 10, 11, 12, 12
median = 8 + 10 / 2 = 18 / 2 = 9
median = 9
The range is the largest number minus the smallest number.
Therefore,
range = 12 - 7 = 5
range = 5
The mode is the number that appears most. Therefore,

Answers
Answer:
y=4x-20
Explanation:
Since we already have a slope, all we need to do is just find the y-intercept. To do this we can make an XY t-chart.
Using the chart we can see that for every x that decreases, a y decreases 4 times. So if we subtract 5 from x, we will multiply 5 times y. Note that this graph is increasing so the y-intercept is negative. -5 · 4 = -20
X | Y
6 | 4
5 | 0
0 | -20

Two runners are saving money to attend a marathon. the first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. the second runner has $50 in savings and will save $60 each month. which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money? 112 – 25m 45 = 50 – 60m 112 25 45m = 50m 60 112 25 – 45m = –50m 60 112 25m 45 = 50 60m
Answers
The equation that we need to solve is:
$157 + $50*m = $50 + $60*m
And the solution is m = 10.7 months.
Which equation models the situation?For the first runer we have a initial amount of $112 + $45 = $157 plus $50 per month, so we can write:
f(m) = $157 + $50*m
And the second runner has an initial amount of $50 and saves $60 per month, so we can write the linear equation:
g(x) = $50 + $60*m
They will have the same amount of money when:
f(x) = g(x)
$157 + $50*m = $50 + $60*m
$107 = $10*m
$107/$10 = m = 10.7
So, after 10.7 months, both accounts will have the same money.
