Answer:
Infinite solutions
Step-by-step explanation:
This question seems a little weird, when you have x^2 = 0 and put it into a graphing calculator, it seems to look like a never ending vertical line. So I believe it should be infinite.

Step-by-step explanation:
What is the INTERQUARTILE RANGE for the data: , 3, 4, 4, 6, 7, 7, 9,
Answer:
The interquartile range for this data set is 3.
Step-by-step explanation:
We are given the data set : 3, 4, 4, 6, 7, 7, 9
In order to find the interquartile range, we can create a box plot for this data set. Each box plot contains a minimum, lower quartile, median, higher quartile, and maximum. Let's find the minimum and maximum before the others as it is the easiest one to identify. The minimum here would be 3 since that's the lowest number here in this data set. The maximum here would be 9 since that's the highest number here in this data set. Before we find the lower and higher quartile, let's find the median first since that way, we don't get mixed up between so many numbers. To find the median, you need to find the value that lies at the middle point throughout the data set. Since there are 7 values in this data set which is a odd number, all we need to do is cross out the first and last value as each set goes by.
3, 4, 4, 6, 7, 7, 9
4, 4, 6, 7, 7
4, 6, 7
6
The work above shows each set of the first and last value getting shorter and shorter, so the median of the data set would be 6. The values, 3, 4, and 9 have already been used. Now that we know the median, the second lowest number here is 4 (lower quartile) and the second highest number here is 7 (higher quartile). In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.
7 (higher quartile) and 4 (lower quartile) = 3 (interquartile range)
Therefore, the interquartile range for this data set is 3.

One angle of a right measures 79°. What is the measure of the other acute angle?
Answer:
11
Step-by-step explanation:
Sum of all angles = 180
Right angle = 90
Acute angle = 79
90+79 =169
180 -169 = 11
Answer:
11 degrees
Step-by-step explanation:
a right angle = 90 degrees
90-79=11 degrees
Factor each polynomial using the Greatest Common Factor.
Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)

what is x? Options: 81, 57, 143, 66.
Answer:
x = 103
Step-by-step explanation:
In my opinion, because x and 77 are the supplementary angles, so 180-77 = x or x+77=180. The answer should be 103......even though it's not in the options (I'm sorry).
Answer:103 degrees
Step-by-step explanation:
Straight line equals 180 degrees
180 degrees minus 77 degrees = 103 degrees

Sana's mother bought produce for Sunday dinner. She bought one more pound of peaches than of tomatoes. She bought 3 times as many pounds of tomatoes than pounds of mushrooms. If peaches cost $6 per lb, tomatoes cost $3 per lb, and mushrooms cost $10 per lb, how many of each did Sana's mother buy for $80?
Please explain how you got the answer like the steps and please dont link any files
1(Identifying):
Tomatoes-x--$3 per lb
Mushrooms- 1/3 x-- $10 per lb
Peaches- x+1-- $6 per lb
2(Equation):
3x+6(x+1)+1/3x*10=80
3x+6x+6+10/3 x=80
12 1/3 x= 74
x=74÷(12+1/3)
Step 3(Final Equations):
74*3/37=6=tomatoes
Meaning...
6+1=7=Peaches
6/3=2= mushrooms
Answer:
7 lb of peaches, 6 lb of tomatoes, and 2 lb of mushrooms
Answer:
7 lb of peaches, 6 lb of tomatoes, and 2 lb of mushrooms

Find the probability. Write answer as a reduced fraction using the forward slash (/).
You have 10 blue marbles, 8 red marbles, and 6 white marbles in a bag. You pick a red marble and put it back, pick a blue marble and put it back, and then pick a red or white marble.
Answer: depends on which probability you want (tell me and I’ll edit)
Step-by-step explanation:
10 blue
8 red
6 white
24 total
Pick a red marble: 8/24 or 1/3
Pick a blue marble: 10/24 or 5/12
Pick red or white: 14/24 or 7/12
do you want to know the probability of doing all that (pick red, put back, pick blue, put back, then pick red or white)? Or just the probability of each outcome?

A certain triangle, one angle measures ten degrees more than the second angle and ten degrees less than the third angle. What is the measure of the smallest angle?
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°

The complex polygon below represents the layout of a parking lot. Find the area of the parking lot in square meters.
Answer:
The area of the parking lot is: 144cm^2
Step-by-step explanation:
Given
See attachment for polygon
Required
The area of the parking lot
The attached plot has 6 congruent triangles with the following dimension;
[tex]Base = 6cm[/tex]
[tex]Height = 8cm[/tex]
[tex]Area = \frac{1}{2} * Base * Height[/tex]
[tex]Area = \frac{1}{2} * 6cm * 8cm[/tex]
[tex]Area = 24cm^2[/tex]
The area of the 6 triangles is:
Area = 6 * Area of 1 triangle
[tex]Area = 6 * 24cm^2[/tex]
[tex]Area = 144cm^2[/tex]
On his way to a job site, Spencer stops to buy bags of concrete mix. Each bag weighs 60 pounds. Spencer’s truck can carry at most 1,700 pounds, and he already has 320 pounds of tools and other equipment in his truck. What are the possible numbers of bags of concrete mix Spencer can buy?
Answer:
28 bags but see below
Step-by-step explanation:
Start by subtracting 320 from 1700
1700 - 320 = 1680
Now he can buy any number of bags as long as he doesn't go over 1680 pounds. Let's see what that means
1680 / 60 = 28 bags of cement.
The answer to the math problem is 28 bags.
In real life, you likely want to trim it that close. What if you hit a bump. That would be very hard on the springs. I'd drop it down to 26 bags if I was actually transporting concreate mix.
He could by any number of bags between 1 and 28 in a math class and a few less in actual practice.
