What is the value of x that would prove the quadrilateral is a parallelogram?
A. 1
B. 2
C. 3
D. 4
E. 5
Answers
If we substitute 3 into the x values in each equation we can see that the top and bottom is the same value and both sides are also the same value, meaning that it is a parallelogram;
Top and bottom of parallelogram:
2x + 3
2 (3) + 3
= 6 + 3
= 9
And
x + 6
(3) + 6
= 9
And then the two sides;
6x - 5
6 (3) - 5
= 18 - 5
= 13
And
4x + 1
4 (3) + 1
= 12 + 1
= 13
There are two pairs of equal sides which shows that this is a parallelogram.

New Berlin Corporation has annual fixed costs of $800,000, variable costs of $48 per unit, and a contribution margin ratio of 40 percent.
a. Compute the unit sales price and unit contribution margin for the above product.
b. Compute the sales volume in units required for New Berlin Corporation to earn an operating income of $600,000.
c. Compute the dollar sales volume required for New Berlin Corporation to earn an operating income of $600,000.
Answers
Based on the variable costs and contribution margin, the unit sales price is $80 and the unit contribution margin is $32.
The sales volume in units needed to earn $600,000 is 43,750 units and the amount in dollar sales needed is $3,500,000.
What is the unit sales price and unit contribution margin?The unit sales price can be found as:
= Variable cost / (1 - contribution margin ratio)
= 48 / (1 - 40%)
= $80
Unit contribution margin is:
= Selling price x Contribution margin ratio
= 80 x 40%
= $32
In units, this amount is:
= (Fixed cost + income required) / Contribution margin
= (800,000 + 600,000) / 32
= 43,750 units
In dollar terms the amount needed is:
= Units needed x selling price
= 43,750 x 80
= $3,500,000

if you were to flip the coin 15, how many times will the coin land on tails based on experimental probability? jordan flipped a count of 45 times.His result are below: heads: 24 tails: 21
Answers
Answer:
It will land 7.5 times on tails, which is rounded up to 8 times
Step-by-step explanation:
there are 2 possibilities, heads or tails
so you divide 15 in 2 and get 7.5
The coin will land 7 times tail based on the experimental probability.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
When the coin tossed 45 times.
Head= 24, tail = 21
So, fraction of appearing tail will be
= 21 / 45
= 0.466667
Now, if the coin tossed 15 times then the coin land on tails
= 15 x 0.466667
= 7

13. Write a system of linear equations that has the ordered pair (3, -5) as its solution.
Answers
Answer:
[tex]x + y = -2\\x-y=8[/tex]
Step-by-step explanation:
3 is the [tex]x[/tex], and -5 is the [tex]y[/tex].
1) Create two equations that add and subtract them.
[tex]x + y = -2\\x-y=8[/tex]
2) Check whether you get the same answer (3,-5) or not. To do so, you need to solve them simultaneously using the elimination or substitution method. I will demonstrate using the substitution method.
[tex]x = -2 - y\\x-y=8\\(-2 - y) -y =8\\-2-2y=8\\-2y = 8 + 2\\-2y = 10\\y = \frac{10}{-2} \\y = -5[/tex]
To find [tex]x[/tex], substitute the result into one of the two equations. I choose [tex]x+y=-2[/tex].
[tex]x-5=-2\\x = -2 +5\\x = 3[/tex]

Step-by-step explanation:
The area of a parallelogram is given by the formla ...
A = bh . . . . . . where b is the base length and h is the height
__
Here, the base is divided into parts, but their total length is 5m+9m = 14m. The height is given as 8m, so the area is ...
A = (14 m)(8 m) = 112 m²
The area of the parallelogram is 112 square meters.
__
Alternate solution
You can also figure this as the sum of the areas of the two triangles and that of the center rectangle.
A = 2(1/2bh) +bh
A = 2(1/2(5 m)(8 m)) +(9 m)(8 m) = 40 m² +72 m² = 112 m²
8. When solving the equation (2 - x)(x + 1) = 11, Priya graphs y=(2 - x)(x + 1) - 11 and then looks to find where the graph crosses the x-axis.
Tyler looks at her work and says that graphing is unnecessary and Priya can set up the equations 2 - x = 11 and x + 1 = 11, the solutions
are x = -9 or x = 10.
A) Do you agree with Tyler?
yes
no
Answers
Answer:
No
Step-by-step explanation:
Tyler is incorrect. The only way you can set individual terms equal to the result is when the result is zero. This is due to zero times anything equalling zero. If one of the terms equals zero, then the other term does not matter because the whole thing will be zero. Let's say:
[tex](2 - x)(x + 1) = 0[/tex]
If the first term equals zero, the entire left side is zero. For Priya's case, the right side is not zero, it is 11. If one term is 11, the other term will contribute. You can check this by plugging in Tyler's solutions. The correct way to solve this equation is to use FOIL on the two terms, then subtract 11 on both sides to get zero. Then use the quadratic formula.

First, we need to find how many years are in between 1977 and 2004:
2004-1977 = 27
And the different between the prices:
175-15 = $160
Since this is supposed to be linear, we can do 160/27 which is about 5.925.
We can round this out to be about $6 cheaper per year, or $5.90.

Answer:

Step-by-step explanation:
7 times 5 equals 35. Even though the two numbers are positive, the product will be negative, because a negative times a negative equals a positive. A negative times a negative will equal a positive because what was originally negative has been reversed in direction.
So, the answer is 35.
