Would any three squares
form the sides of a right
triangle? Explain.
Three squares of sides 15 units, 9 units, and 12 units can form a
right-angled triangle.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
Given, We have to form a right-angled triangle that has side lengths of
3 different squares.
Let, The first square has a side length of 9 units, and let this be the height of the right-angled triangle.
Another square has a side length of 15 units and this is the hypotenuse.
Therefore, the base of the triangle must be 15² - 9² = 225 - 81 = 144 = 12 units.
So, The third square must have a side length of 12 units.

Which statements about the system are true?
Select TWO options.
y = 1/3x - 4
Зу - х = -7
A. The system has one solution.
B. The system consists of parallel lines.
C. Both lines have the same slope.
D. Both lines have the same y-intercept.
E. The equations represent the same line.
2 Answers:
B) The lines are parallelC) The lines have the same slope.Parallel lines always have equal slope, but different y intercepts.
==========================================================
Explanation:
Let's solve the second equation for y
3y - x = -7
3y = -7+x
3y = x-7
y = (x-7)/3
y = x/3 - 7/3
y = (1/3)x - 7/3
The equation is in y = mx+b form with m = 1/3 as the slope and b = -7/3 as the y intercept. We see that the first equation, where y was already isolated, also has a slope of m = 1/3. The two equations of this system have the same slope. Choice C is one of the answers.
However, they don't have the same y intercept. The first equation has y intercept b = -4, while the second has b = -7/3. This means that they do not represent the same line. They need to have identical slopes, and identical y intercepts (though the slope can be different from the y intercept of course) in order to have identical lines. So we can rule out choice D and E because of this.
Because the two equations have the same slope, but different y intercepts, this means the lines are parallel. Choice B is the other answer.
Parallel lines never touch or intersect, which in turn means there is no solution point. A solution point is where the lines cross. We can rule out choice A.
I recommend using your graphing calculator, Desmos, GeoGebra, or any graphing tool (on your computer or online) to graph each equation given. You should see two parallel lines forming. I used GeoGebra to make the graph shown below.

Each fier station hose at the la salle fier station is 25 yards long. The station needs enough fier hoses to reach from any fier hoses to reach from any fier hydrant to the farthest house wich could be up to 230 feet away. What is the minimum number of hoses that the la salle fier station should have.
Answer:
4
Step-by-step explanation:
minimum number of hoses needed = farthest length / length of a hose
convert the length of a hose to feet
1 yards = 3 feet
25 x 3 = 75 feet
230 / 75 = 3.1
4 hoses would be needed
Each bar includes the left-end value but not the right-end value. For example, the first bar
includes dogs that weigh 60 pounds and 68 pounds but not 80 pounds.
Step-by-step explanation:
Answers:
How many dogs weigh at least 100 pounds?
14 + 5+ 3 + 1 = 23 dogs.
How many dogs weigh exactly 70 pounds?
is unknown, so will be 60-79 .
How many dogs weigh at least 120 and less than 160 pounds?
8 dogs weigh 120 less than 160 pounds.
How much does the heaviest dog at the show weigh?
is unknown, but could be between - 160-179
What would you consider a typical weight for a dog at this dog show? Explain your reasoning.
A typical dog weighs can be 100 - 120.

What is the midpoint of the segment shown below?
0.2x + 0.3 = 0.1x + 0.5
Answer:
x = 2
Step-by-step explanation:
0.2x + 0.3 = 0.1x + 0.5 ( subtract 0.1x from both sides )
0.1x + 0.3 = 0.5 ( subtract 0.3 from both sides )
0.1x = 0.2 ( divide both sides by 0.1 )
x = 2

A survey was done to determine the amount of electricity used by residents in a local community. The survey data was compiled into the histogram below. Identify the approximate number of participants in the survey.
a) 150
b) 200
c) 350
d) 450
Given:
The histogram of a survey that represents the amount of electricity used by residents in a local community.
To find:
The approximate number of participants in the survey.
Solution:
Using the given histogram, we get the frequency table:
Electricity usage Frequency
50 23
150 34
250 25
350 26
450 42
Sum of frequencies is:
[tex]23+34+25+26+42=150[/tex]
It means the total number of participants in the survey is 150.
Therefore, the correct option is (a).

Joshua has a rectangular work table. The sides of the table are 40 inches by 25 inches. What is the length of the diagonal of the table.
Given:
Dimensions of the rectangular table are 40 inches by 25 inches.
To find:
The length of the diagonal of the table.
Solution:
Diagonal of a rectangle is:
[tex]d=\sqrt{l^2+w^2}[/tex]
Where, l is the length and w is the width of the rectangle.
Putting [tex]l=40,w=25[/tex] in the above formula, we get
[tex]d=\sqrt{(40)^2+(25)^2}[/tex]
[tex]d=\sqrt{1600+625}[/tex]
[tex]d=\sqrt{2225}[/tex]
[tex]d\approx 47.17[/tex]
Therefore, the length of the diagonal is about 47.17 inches.

The amount of gallons of water remaining in a swimming pool after x hours is given by the equation,
y = -4,000x + 20,000
How long before the pool is completely drained?
O 1 hour
5 hours
3 hours
6 hours
Answer:
5 hours
Step-by-step explanation:
The pool will be completely drained when y = 0
0 = -4,000x + 20,000
subtract 20,000 from both sides
-20,000 = -4,000x
divide both sides by -4,000
x = 5
Have a good day!
Answer:
5 hours.
Step-by-step explanation:
When it is drained y will be = to zero, so
-4000x + 20000 = 0
-4000x = -20000
x = -20000/ -4000
= 5.
