Point J is on line segment IK. Given IK = 15 and JK = 6, determine the
length IJ.
Answer:
[tex]\huge\boxed{IJ = 9}[/tex]
Step-by-step explanation:
Given that J is on line segment IK.
So, it is like:
I______?_______J___6___K
|<--------------------15---------------->|
We know that:
IK = IJ + JK
Where IK = 15 and JK = 6
15 = IJ + 6
Subtracting 6 to both sides
IJ = 15 - 6
IJ = 9

Answer:
≤
Step-by-step explanation:
First we solve 5(x + 2) ≥ 2(x + 8).
5x + 10 ≥ 2x + 16
3x ≥ 6
x ≥ 2.
Now we place an equal sign into the box:
4(x - 6) = 2(x - 10)
4x - 24 = 2x - 20
2x = 4
x = 2.
For the solution to only have 1 value, the solution must be x = 2.
Therefore we must have x ≥ 2 and x ≤ 2.

At a concert 60% of the audience are adults . 25% of those remaining are boys and the rest of the audience members are girls .There are 30 girls altogether. How many a people are the at the concert?
Answer:
1800 people were at the concert.
Hello there! :D
Its math time!!
Alright, let's write out all the percentages.
60%= adults
25%= boys
There are thirty girls.
We can find out what percentage of the people there are girls by adding the percentages of the adults and boys and subtracting that from 100.
60+25= 85
100-85=15
So, 15% of the audience are girls. That is equal to 30 people.
I also know that 60 is divisible by 15 and 4. So, if we multiply 30 by 4 we can find out how many adults are at the concert.
30*4= 120 adults
We can also take 15 and divide it by 3 (as well as 30) so we can find out how many people there are for 5% of the concert. That will make it easier to find out how many boys there are.
15/3= 5%
30/3=10
Now we just need to know how many fives go into 25, which is 5.
5*10= 50
Add that to the number of adults and girls:
50+120+30= 200 people
There are 200 people at the concert!
I hope this helped you and you have a wonderful day,

how much dose the least expensive 50 present of trail mix cost? what is the least of 4 pounde of trail mix can cost
The box-whisker plot is missing. Check the attachment for the data.
The least expensive 50% of trail mix costs between $1.25 and $2.75 per pound, as these, depict the minimum point and the median (50% of data), of the given box-whisker plot.
The least 4 pounds of trail mix can cost $6.00, at the minimum rate shown in the box-whisker plot by its starting point of $1.25 per pound.
What is a box-whisker plot?A box-whisker plot is a diagrammatic representation of data. The whiskers start from the minimum data and go up to the maximum. In between the whiskers is a box that starts from the first quartile of the data (below which 25% of the data lies) and goes up to the third quartile (below which 75% of the data lies). In between the box is a line, that indicates the median of the data. The median is the value of the middlemost data.
How to solve the given question?In the question, we are given a box-whisker plot, showing the different costs of trail mix at different prices per pound.
1. We are asked how much the least expensive 50% of trail mix costs.
We know that 50% of data is depicted at the median which is the line in between the box in a box-whisker plot. So the least expensive 50% is shown before the line.
The minimum point in the data is $1.25 and the median is $2.75.
Hence, the least expensive 50% of trail mix costs between $1.25 and $2.75 per pound, as these depict the minimum point and the median (50% of data), of the given box-whisker plot.
2. We are asked to find the least cost of 4 pounds of the trail mix.
We know that the starting point of the whisker shows the minimum point in the data. Hence, the least cost of the trail mix is $1.25 per pound.
So, the cost of 4 pounds is $1.25 * 4 = $6.00.
Hence, the least 4 pounds of trail mix can cost $6.00, at the minimum rate shown in the box-whisker plot by its starting point of $1.25 per pound.

Answer:
[tex]u<-1\text{ or } u>2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-3|2-4u|+5<-13[/tex]
First, subtract -5 from both sides:
[tex]-3|2-4u|<-18[/tex]
Divide both sides by -3. Since we are dividing by a negative, we will flip the sign:
[tex]|2-4u|>6[/tex]
Definition of absolute value:
[tex]2-4u>6\text{ or } 2-4u<-6[/tex]
Note that we flip the sign on the right because we multiplied 6 by a negative.
On both the left and right, subtract 2:
[tex]-4u>4\text{ or } -4u<-8[/tex]
Divide both equations by -4. Since we're dividing by a negative, flip the signs:
[tex]u<-1\text{ or } u>2[/tex]
So, our final solution is:
[tex]u<-1\text{ or } u>2[/tex]
And we're done!
You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the number of dimes. Is your friend correct? Let d represent the number of dimes
An equation that models this situation is _____=2.80
(I’m so stupid help)
Answer:
Step-by-step explanation:
d = number of dimes
2.80 = 0.1d + 0.25 (d + 8 )
2.80 = 0.1d + 0.25d + 2 Combine like terms
2.80 = 0.35d + 2 Subtract 2 from both sides
0.80 = 0.35d Divide both sides by 0.35
d ≈ 2.29
No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.

so 90° - 19 = 71
2. Continuous data are usually _____________________, but discrete data are usually ______________________.
Answer:
Measured and Counted.
Step-by-step explanation:
Continuous data are usually “Measured”, but discrete data are usually “Counted”.
The continuous data are the data that can be measured, for example, Height of children, time in the race, length of leaf, etc. In this case, the data is taken within the range. While the discrete data is the data that can be counted. For example, the number of employees in the office, the number of students in the school, the result of rolling dice, etc. In this case, the data is a fixed number. Accordingly, the continuous data is measurable and discrete data is countable.
How do you find the domain and range of a function and write it in set notation? What is the process of finding it? Tips and tricks are very much appreciated. I literally have no clue how to get them. Send help?
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
Step-by-step explanation:
plz forgive me if my answer is wrong
Domain = looking for the very far left value and the very far right value on the x-axis, and only x-axis, so the farthest left x-axis value and the farthest right x-axis value.
Range = very bottom y-value, and very top y-value
In both cases, if the arrows extend forever then that means you could have the value of infinity.
If you go on a road trip of 270 miles in the mountains and 7/ 10 of the trip is downhill, how many miles of the trip are not downhill? Reduce to the lowest terms.
Answer:
81 miles
Step-by-step explanation:
From the question 7/10 of the trip has been said to be downhill. It therefore means that 3/10 is not downhill.
Miles = 270
Downhill = 7/10
Not downhill = 3/10
Now we have To calculate Miles that are not downhill (uphill)
But first I calculated for the number of downhill miles
270x7/10
Downhill = 189 miles
To get the number of not downhill miles
I subtracted 189 from the total number of miles on the question.
270 - 189
= 81 Miles.
Therefore 81 Miles of the trip are not downhill.

Answer: see below
Step-by-step explanation:
Write each equation in y = mx + b format where m is the slope and b is the y-intercept.
Left side: -4 ≤ x < -1
If you continue the line through the y-axis it will pass through (0, 4) --> b = 4
The rise over run is -1 over 1 --> m = -1
y = (-1)x + (4) --> y = -x + 4
Right side: -1 < x < 4
The line passes through (0,0) --> b = 0.
The rise over run is -1 over 1 --> m = -1
y = (-1)x + (0) --> y = -x
