Use the vertices to find the length and width of the rectangle:
Length = (0,0) (0,4) = 0-0 = 0, 4-0 = 4

Is there a direct proportion in 2y-5=x? If there is one, what is the constant of proportionality?
Answers
=========================================
Explanation:
Solve for y
2y-5 = x
2y = x+5
y = (x+5)/2
y = (x/2) + (5/2)
y = 0.5x + 2.5
The last equation is in the form y = mx+b where m = 0.5 is the slope and b = 2.5 is the y intercept. The y intercept must be b = 0 in order for the graph to go through the origin. Since b = 2.5 is not zero, this is why we don't have a direct proportion.
Note: direct proportions are often written in the form y = k*x which is basically y = mx+b, but the m has been replaced with k and the b is removed (because b = 0)

A bargain bin contains classical and rock and CDs. There are 60 CDs in the bin. Choosing a rock CD have the same number of favorable outcomes. How many rocks CDs are in the bin
Answers
The bin should contain 30 rock CDs, which constitutes half of the total CDs (60). This conclusion is reached by dividing the total number of CDs by 2, as the question implies an equal probability of picking a rock or classical CD.
Explanation:The question pertains to the concept of probability in mathematics. Here, the total number of CDs is specified as 60. If choosing a rock CD has the same number of favorable outcomes, it means that half of the CDs are rock CDs (as the other half would then be classical CDs). So, to find the number of rock CDs in the bin, you simply divide the total number of CDs by 2. Here, 60 CDs divided by 2 equals 30. Thus, there are 30 rock CDs in the bin.

The radius of circle O is 24,and OC = 11. What is the length of AB?
Answers
42.7
Answer: The correct option is (A) 42.7 units.
Step-by-step explanation: Given that the radius of the circle center at O is 24 units and OC is 11 units.
We are to find the length of chord AB.
We have,
in the right-angled triangle OCB (m∠OCB = 90°),
OB = 24 units and OC = 11 units.
Using Pythagoras theorem in ΔOCB, we have
[tex]OB^2=OC^2+BC^2\\\\\Rightarrow BC=\sqrt{OB^2-OC^2}\\\\\Rightarrow BC=\sqrt{24^2-11^2}\\\\\Rightarrow BC=\sqrt{576-121}\\\\\Rightarrow BC=\sqrt{455}\\\\\Rightarrow BC=21.33.[/tex]
Since OC is perpendicular to chord AB, so AC = BC.
Therefore, we get
[tex]AB=AC+BC=2\times BC=2\times 21.33=42.66=42.7.[/tex]
Thus, the required length of AB is 42.7 units.

the annual health insurance premium for Ms. Everett is $12,304 her employer says 70% of the premium and deducts the remainder from her paycheck Ms. Everett is paid monthly what amount is deducted from Ms. Everett paycheck for her health insurance premium.
$141.97
$307.60
$331.26
$717.73
Answers
Her portion will be $3,691.20
If you spread that out over 12 months (3,691.20/12) it comes out to $307.60
To find the amount deducted from Ms. Everett's paycheck for her health insurance premium, calculate 70% of the annual premium, subtract the employer's contribution, and divide by 12 for the monthly deduction, resulting in $307.60. The correct answer is B.
To calculate the amount deducted from Ms. Everett's paycheck for her health insurance premium, first, find 70% of the annual premium:
70% of $12,304 = 0.70 x $12,304 = $8,612.80
The remainder that Ms. Everett must pay is the annual premium minus the employer's contribution: $12,304 - $8,612.80 = $3,691.20
Since Ms. Everett is paid monthly, divide the annual amount by 12 to find the monthly deduction: $3,691.20 ÷ 12 = $307.60
Therefore, the amount deducted from Ms. Everett's paycheck for her health insurance premium is $307.60.

In, 30-60-90 degree triangle ,
the sides are in the ratio [tex]1: \sqrt{3} :2[/tex]
[tex]sin(60)= \frac{opposite}{hypotenuse}[/tex]
for 60 degree, opposite side = square root (3)

There are 2500 students in the school. Find the number of students in the sample who said they will vote for Candidate C. Then predict the number of students in the school who will vote for Candidate C. Candidate A is 25%, Candidate B is 15%, and Candidate C is 60%.
Answers
Final answer:
The sample size is calculated to be 200 based on the percentage for Candidate A. From the sample, 120 students said they will vote for Candidate C. Predicting based on this sample, 1,500 students in the school will vote for Candidate C.
Explanation:
To find the number of students in the sample who said they will vote for Candidate C, we need to use the percentages given for each candidate. If Candidate A is 25%, Candidate B is 15%, and Candidate C is 60%, and knowing that 50 students in the sample voted for Candidate A, we can determine the total sample size. Since Candidate A represents 25% of the sample, we can calculate the total sample size using the equation 50 = 0.25 × (total sample size). Solving for total sample size gives us 200.
With the sample size known, we can calculate the number of students who said they will vote for Candidate C by taking 60% of 200, which is 120 students in the sample. To predict the number of students in the school who will vote for Candidate C, we use the proportion of the sample who choose Candidate C to estimate the proportion for the entire school population. Since there are 2,500 students in the school, we predict that 60% of 2,500 will vote for Candidate C, which amounts to 1,500 students.

PQ bisects ∠SPY. m∠SPQ =[tex] \frac{11}{2}
[/tex] x-5 and m∠YPQ= 4x- [tex] \frac{5}{2} [/tex]
Solve for x and find m∠SPY
Answers
Since PQ bisects the angle, the two angles formed by the bisector are equal:
11/2x - 5 = 4x - 5/2
We will first multiply everything by 2 to eliminate the fractions:
(11/2x)*2 - 5*2 = 4x*2 - (5/2)*2
11x - 10 = 8x - 5
Subtract 8x from each side:
11x - 10 - 8x = 8x - 5 - 8x
3x - 10 = -5
Add 10 to both sides:
3x - 10 + 10 = -5 + 10
3x = 5
Divide both sides by 3:
3x/3 = 5/3
x = 5/3
Now we will plug this in for x in both smaller angles and add them together to find the measure of ∠SPY:
11/2(5/3) - 5 + 4(5/3) - 5/2
55/6 - 5 + 20/3 - 5/2
We will rewrite everything using a denominator of 6:
55/6 - 30/6 + 40/6 - 15/6 = (55-30+40-15)/6 = 50/6 = 8 2/6 = 8 1/3°
how to solve -6<-2x<14
Answers
-6 < -2x < 14
We're trying to solve for x. To solve for x, we must isolate x.
So, let's divide everything by -2!
-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2
**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **
3 > x > -7
So, our answer is : → 3 > x > -7

a number is chosen at random from 1 to 50. find the probability of selecting divisors of 12
Answers
First of all, we need to know how many divisors 12 has.
12: 1, 2, 3, 4, 6, 12
Since there are 6 divisors of 12, this means the probability is 6/50.
You could just stick with 6/50 as your answer, but most probability is measured in percents so we'll convert 6/50 into a percent.
Percents are measured out of 100, so to make 6/50 into a percent we need to do some cross-multiplying.
[tex] \frac{6}{50} = \frac{x}{100} [/tex]
First, multiply 6 by 100
6 × 100 = 600
Next, divide the product by 50.
600 ÷ 50 = 12
So, your final answer is:
As a ratio:
[tex] \frac{6}{50} = \frac{12}{100} [/tex]
As a fraction:
12/100 or 6/50
As a percent:
12%
