A ballroom has a square dance floor. The area of the floor is 400 square feet.
If the length of each side of the square increased by one foot, would its area be a rational number?
Choose all that apply.
Answers:
A. - The area of the floor would be a rational number.
B. - The area of the floor would be an irrational number.
C. - Each side length would be a perfect square.
D. - The area of the floor would be a perfect square.
E. - The area of the floor would be a nonterminating, nonrepeating decimal.
Answer:
D
Step-by-step explanation:
Area of square=400sq.ft
or,l²=400sq.ft
or,l=(400sq.ft)½
or,l=(20²sq.ft)½
or,l=20ft
Thus,length of square is 20ft.
If length of square is increased by 1 ft then ,
New length=(20+1)ft=21ft
Area of square=(21ft)²
=441sq.ft

Answer:
Step-by-step explanation:
This is a definite maybe kind of question.
Start with the 280. It has a range of 280 +/- 10 mL. That means that each serving is between 270 and 290. If she serves exactly 280 every time she will need 22 * 280 = 6160 mL or 6160/1000 = 6.16 L which gives her a margin of 0.340 L or 340 mL
Consider 270 mL
270 mL * 22 = 5940 mL or 5.94 L She has a little over 1/2 L left over. She has enough soup for 22 people.
Finally think about 290 per serving
290 * 22 = 6380. This should work as well providing she has more than 6.38 Liters which is not a slam dunk. With a leeway of 0.5 L and she only makes 6 Liters, she does not have enough.
So maybe. (Since you can explain this question, you can, I should think, use 0.5 Liters as a leeway).
There is one condition I have not considered and that is what happens if you have 7 Liters of soup? Then the leeway in the serving size does not matter.

How do I solve it ? I don’t understand
Answer:
1) 3 Points Include: E, B and F. To explain in Detail. Point E, which is (-1,1) Point B, which is (0,-2) and Point F, which is (2,3) The Directions tell you to name 3 Points on the image. The points I just explained are all on the graph, so they are all points in the Image.
Two Lines are: Lines CD and Lines AB. These are both lines on the images. The points A and B are connected with a line, so they are a line on the graph. The Points C and D are also connected by a line, therefore, both lines CD and AB are lines on the image.
A Line Segment: A line segment is a line connected with two end points, You can say a line is a segment when both ends of the line have a dot, also known as a point. One line segment in this image is Line EB, both the points are connected by a line, and both sides of the line have a point.
The Plane: The plane is the entire surface that everything is on. The plane has all the lines, segments, and points. All planes extend infinitely far. We can see, the plane is "O". The letter O is located towards the middle of the graph, Therefore, the Plane is "O"
2)One Point: On the Plane, one point is point S. Q and R are also points, but the question only asks for one point.
The Line: There is only one line on the plane, this line is line QR. Both points Q and R are connected by a line.
The Plane: The Plane is "T" in the bottom left of the image, in the corner of the plane (the plane is the blue area) you can see the letter T. "T" is the plane.
Does the line go through the Plane? Yes. The line does go through the plane. Here's why: On the line QR, both sides of the line have arrows. If a line has arrows that means the line goes on forever in the direction the arrow is pointing. If a line has two dots, its a segment, which means the lines end at the points, they do not go on forever. In this case, the line goes on forever and it goes through the blue area, which is the plane.

The perimeter of a rectangle is 60 meters. Its length is 10 meters. What is its width?
Answer:
[tex]\boxed {\tt 20 \ meters}[/tex]
Step-by-step explanation:
The perimeter of a rectangle can be found using the following formula.
[tex]p= 2l+2w[/tex]
We know the perimeter is 60 meters and the length is 10 meters.
[tex]p=60 \ m[/tex]
[tex]l= 10 \ m[/tex]
Substitute the values into the formula.
[tex]60 \ m = 2(10 \ m) + 2w[/tex]
Multiply 2 and 10.
[tex]60 \ m = 20 \ m +2w[/tex]
Subtract 20 from both sides of the equation.
[tex]60 \ m - 20 \ m = 20 \ m - 20 \ m +2w[/tex]
[tex]60 \ m - 20 \ m =2w[/tex]
[tex]40 \ m = 2w[/tex]
Divide both sides of the equation by 2.
[tex]\frac{40 \ m}{2} =\frac{2w}{2}[/tex]
[tex]\frac{40 \ m}{2} =w[/tex]
[tex]20 \ m =w[/tex]
The width of the rectangle is 20 meters.

The rise and span for a roof is the ratio of the rise to the half-span. If the rise is 8 feet and the span is 30 feet,what is the pitch in simplest form?
Answer:
8 feet to 15 feet or [tex]\dfrac{8}{15}[/tex].
Step-by-step explanation:
We know that pitch is is the ratio of the rise to the half-span.
It is given that, the rise is 8 feet and the span is 30 feet.
[tex]\text{Half of span}=\dfrac{30}{2}=15[/tex]
We need to find the pitch in simplest form.
[tex]Pitch=\dfrac{\text{Rise}}{\text{Half-span}}[/tex]
[tex]Pitch=\dfrac{8}{15}[/tex]
Therefore, the pitch in simplest form is 8 feet to 15 feet or [tex]\dfrac{8}{15}[/tex].
IF HJ = 7x-27, find the value of x
Answer:
x= (1/7)hj + (27/7)
Step-by-step explanation:
1) Flip the equation:
7x-27=hj
2) add 27 to both sides
7x = hj +27
3) divide both sides by 7
x = 1/7hj + (27/7)
