18. Use an inequality symbol (<, >,=, s) to compare -3 +7_-10 - 2
A. s
B.>
C. =
D.<
Answer:
-3 +7 > -10 - 2
Step-by-step explanation:
Given
-3 +7_-10 - 2
Required
Compare using any of the given inequality symbols
We start by solving both sides of the inequality
- 3 + 7 _ -10 - 2
(-3 + 7) _ (-10 - 2)
(4) _ (-12)
Having solved both sides of the inequality, it'll be observed that 4 (on the left hand side) is greater than -12 (on the right hand side);
Hence, the _ symbol can be replaced by the greater than symbol.
(4) _ (-12) can then be rewritten as
(4) > (-12) or
- 3 + 7 > -10 - 2
From the list of given options, option B is correct

30. The box-and-whisker plot shows the average temperatures in Tucson, Arizona in December. (1 point)
Which statement about the temperatures in Tucson must be true?
About half of the days in December had average temperatures above 60 degrees.
About half of the days in December had average temperatures between 52 and 60 degrees.
The coldest day in December was 52 degrees.
The hottest day in December was 65 degrees.
Answer:
About half of the days in December has average tempetare between 52 and 60 degrees
(SEE THE ATTACHMENT)
Step-by-step explanation:
See the box-and-whisker plot.
Median = 58
1st quartile (which is the median of all value below 58) = 52
2nd quartile (which is the median of all value above 58) = 60
From 1st quartile to median = Almost quarter of the values
From median to 2nd quartile = Almost quarter of the values
From 1st quatile to 2nd quartile = Almost half of the values
So
1st statement is wrong
2nd statement is correct
3rd statement is wrong (Coldest day was 49 degrees)
4rth statement is wrong (Hottest day was 68 degrees)

Consider a circle whose equation is x2 + y2 + 4x - 6y - 36 = 0. Which statements are true? Check all that appl"
To begin converting the equation to standard form, subtract 36 from both sides.
mu To complete the square for the x terms, add 4 to both sides.
Answer:
To complete the square for the x terms, add 4 to both sides.To convert the given equation of the circle to standard form we should do as follows.
1. Add 36 to both sides of the equation.[tex]x^{2} +y^{2}+4x-6y-36+36=36\\ x^{2} +y^{2}+4x-6y=36[/tex]
2. We order the terms according to their variables.[tex]x^{2} +4x +y^{2}-6y=36[/tex]
3. Divide the linear term by 2, then elevate it to the square power.[tex]x^{2} +4x + (\frac{4}{2} )^{2} +y^{2} -6y+(\frac{6}{2} )^{2} =36[/tex]
4. Solve operations, and add the same units to the other side of the equation.[tex]x^{2} +4x+4+y^{2} -6y+9=36+4+9\\[/tex]
5. Now, we sum costant terms, and factor both trinomials.[tex](x+2)^{2} +(y-3)^{2} =49[/tex]
As you can observe, the circle has center at (-2,3) and it has a radius of 7 units.
Notice that the second choice is correct, because we added 4 units to both sides to complete the square for the x terms.

AB is a segment with one endpoint A(-7,9) and midpoint M(8,1). Can
you find the coordinates of the other endpoint B?
Enter the x-coordinate of the other endpoint here
Enter the x-coordinate of the other endpoint here
Answer:
x-coordinate of the other endpoint: 23
y-coordinate of the other endpoint: -7
Step-by-step explanation:
To find the x-coordinate of the other endpoint, we need to find the run between the known endpoint and the midpoint
run: xM - xA = 8 - (-7) = 15
where xM and xA are the x-coordinates of M and A respectively.
The run between the other endpoint and the midpoint must be the same as before:
x - 8 = 15
x = 15 + 8
x = 23
To find the y-coordinate of the other endpoint, we need to find the rise between the known endpoint and the midpoint
rise: yM - yA1 = - 9 = -8
where yM and yA are the y-coordinates of M and A respectively.
The rise between the other endpoint and the midpoint must be the same as before:
y - 1 = -8
y = -8 +1
y = -7

An empty swimming pool is going to be filled with water. The swimming pool is a cuboid, that is 25 metres long, 10 metres wide and 2 metres deep. It is being filled at a rate of 800 litres per minute Given 1m3 = 1000 Litres, how long it will take to fill the swimming pool? Give your answer in hours and minutes.
Answer: 10 hours and 25 minutes.
Step-by-step explanation:
Multiply 25, 10, and 2 to find volume. Volume is 500 metres.
1 meter = 1000 litres. 500 * 1000 = 500,000 litres in volume.
500,000/ 800= 625 minutes.
625 minutes = 10 hours and 25 minutes
It take 10 hours and 25 minutes to fill the swimming pool.
The volume of a cuboid is given by the formula:
Volume = Length × Width × Depth
= 25 m × 10 m × 2 m
= 500 m³
Now, convert the rate of filling from liters per minute to cubic meters per minute:
1 m³ = 1000 liters
So, 800 liters per minute = 800/1000
= 0.8 m³ per minute
Next, the time it will take to fill the pool:
Time (in minutes) = Volume / Rate of filling
= 500 m³ / 0.8 m³ per minute
= 625 minutes
Now, 1 hour = 60 minutes
625 minutes = 625 / 60
= 10 hours and 25 minutes
So, it take 10 hours and 25 minutes to fill the swimming pool.

Find the value of x.
Answer:
x=root 70
Step-by-step explanation:
We have three triangles in this picture. The big triangle and 2 small triangles. They are all similar triangles.
Thus, because they are similar we have (7+3)/x=x/7
That gives us 10/x=x/7.
Cross products gives us x^2=70, so x=root 70
Question 1
In this hanger, the weight of the triangle is x and the weight of the square is y.
a. Write an equation using x and y to represent the hanger.
B. If x is 6, what is y ?
Answer:
a. -3x = -2y
When x=6, y=9
Step-by-step explanation:
From the hanger, There are two sides
If x=triangle and y=square
First side has 1 triangle and 3 squares
It can be represented by
x+3y
Second side has 4 triangles and 1 square
It can be represented by
4x+y
Equate the first and second side
x+3y=4x+y
Collect like terms
x+3y-4x-y=0
-3x+2y=0
-3x=-2y
Find y when x=6
-3(6)=-2y
-18=-2y
Divide both sides by -2
-18/-2=-2y/-2
9=y
y=9
The value of y when x = 6 is 9
Given that the weight of the triangle is x and the weight of the square is y.
For the hanger at the left, the resulting equation will be:
x + 3y (1 triangle and 3 square)
For the right-hand side
4x + y (4 triangles and 1 square)
Equating both expressions
x + 3y = 4x + y
x - 4x = -2y
-3x = -2y
3x = 2y
If x = 6, hence;
3(6) = 2y
2y = 18
y = 9
Hence the value of y when x = 6 is 9
