A ballroom has a square dance floor. The area of the floor is 400 square feet. Of the length of each side of the square increased by one foot, would its area be a rational number? Explain.
Answers
Answer:
It is given in the question that
A ballroom has a square dance floor. The area of the floor is 400 square feet.
And the formula of the area of the square sides square.
So we will get
400= side^2
Taking square root on both sides,
side=20
And on increasing the side length by one foot, we will get the side length of 21 feet.
And it is not a perfect square.
And the area is
Area= 21^2 = 441ft^2
And 441 is a perfect square and a rational number.
Therefore true statements are A and E.

These are SIMILAR figures. Fill in the missing values for the angles and sides
Answers
Answer:
75 62 22 30 65 18
Step-by-step explanation:
Given that the figures are similar figures, then:
x and y in the Parallelograms:
x = 88
y = 118°
x, y, and z in the Hexagons:
x = 164°
y = 36
z = 33
x, y, and z in the Triangles:
x = 10
y = 21
z = 75°
What are Similar Figures?Similar figures have pairs of angles that have the same degree measure, and the ratio of their corresponding sides are equal.
Given that the pairs of figures are similar, let's find the missing angles and sides as shown below:
Find x and y in the Parallelograms:
x/66 = 100/75
Cross multiply
x = (100 × 66)/75
x = 88
y = 118° (opposite angles of a parallelogram are congruent)
Find x, y, and z in the Hexagons:
x = 164° (congruent angles)
y/54 = 20/30
y = 36
22/z = 20/30
z = 33
Find x, y, and z in the Triangles:
x/15 = 12/18
x = 10
14/y = 12/18
y = 21
z = 180 - 65 - 40 = 75°

Answer:
[tex]y=-\frac{2}{5} -1[/tex]
Step-by-step explanation:
So first thing is that slope intercept form is setup like this
y=mx+b
m=slope
b=y intercept
the slope is change in y over change in x
as y goes down 2 x goes up 5
so the slope is -2/5
the y intercept is at (0,-1) so the y intercept is -1
therefore the answer is
[tex]y=-\frac{2}{5} -1[/tex]
have a great day :)
Answer:
[tex]y=-\frac{2}{5}x-1[/tex]
Step-by-step explanation:
In order to find the answer, we first need to know the slop form.
y=mx+b
In order to find the slope (m), we need to find at least 2 clear points on the graph. Looking at the graph, we can see that one point is (-5, 1) and (0, -1).
We can use either the formula [tex]\frac{y2-y1}{x2-x1}[/tex] or rise over run. In this scenario, looking at the graph and using rise over run will be the fastest way. Starting at point (0, -1), you have to rise 2 and run 5.
In addition, the line is going into infinite value in the second and fourth quadrant. This tells us that the slope is negative. [tex]m=-\frac{2}{5}[/tex].
To find the b value, all we have to do is find the y-value that is on the y-axis. (0, -1), and the answer is -1.
This, gives use the formula [tex]y=-\frac{2}{5}x-1[/tex]
If you want to check your answer, simply plug in a random point on the line into the formula and the equation will be valid.

3x - 2y = 2
A. Multiply O by 2 and multiply by 3
B. Multiply by 2
C. Multiply O by 2
D. Multiply by 2 and multiply O by -2
Answers
Answer: A
Step-by-step explanation:
The best way to solve the system below by elimination is to multiply
2x + y = -3 by 2.
What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
Equations given
2x + y = -3 -------------------------- (1)
3x - 2y = 2 --------------------------(2)
Now, solving by applying elimination method
Case 1: solving for y , eliminate x
Multiplying equation (1) by 3 and equation (2 ) by 2
6x + 3y = -9
6x - 4y = 4
now subtracting both we will get value of y then we can get x by substituting y in equation
Case 2:
solving for x , eliminating y
Multiply equation (1) by 2
4x + 2y = -6 ---------------------------- (3)
3x - 2y = 2 --------------------------(2)
now, adding both equation will give x value then we can get y by substituting x in equation
Hence, Multiply equation (1) by 2 will be best way .

Kasey and Jordan are counting calories while eating lunch in the school cafeteria. in one week, Kasey had 10 slices of pizza and 5 cups of fruit salad. Jordan had 6 slices of pizza and 7 cups of fruit salad. Kasey’s calorie count was 3070 and Jordan’s was 2522. How many calories are in a slice of pizza?
Answers
Answer:
222 calories from the pizza
Step-by-step explanation:
nandhini123-
Given:
slices of pizza ate by Kasey =10
cups of fruit salad by Kasey= 5
slices of pizza ate by Jordan = 6
cups of fruit salad by Jordan= 7
Kasey's calorie count = 3070
Jordan calorie count = 2522
To Find:
calories Jordan got from pizza =?
Solution:
Let the calorie of one slice of pizza be x
and the calorie of one cup of fruit salad be y
According to the question, the equation that represents the Kasey's Scenario is
10x + 5y = 3070-------------------------------------(1)
Similarly the equation that represents the Jordan Scenario is
6x + 7y = 2522--------------------------------------(2)
multiply eq(1) by 6 we get
60x + 30y = 18420---------------------------------(3)
multiply eq(2) by 10 we get,
60x + 70y = 25220----------------------------------(4)
Subtracting eq (3) from (4) we get
60x + 70y = 25220
60x + 30y = 18420
(-) (-) (-)
-----------------------------------
0x + 40y = 6800
---------------------------------
=>40 y = 6800
=>y =
=> y = 170
So calorie of one cup fruit salad is = 170 calories
substituting the y values in eq 1 we get
10x + 5(170) = 3070
10x + 850 = 3070
10x = 3070 - 850
10x = 2220
x =
x= 222
So calorie of one pizza slice = 222 calories
Now we know that Jordan ate 6 slices of pizza
calories Jordan get from pizza = number of pizza he ate X calore per pizza slice
=> 6 x 222
=>1332 calories
