Answer:
x=3
y=12
Step-by-step explanation:
The scale factor is 1:4
we divide 12 by 4 to get 3
if we multiply 3 by 4 it is 12 so y=12

The bulletin board is in the shape of a square. Find two rational numbers that are within 1/8in. of the actual side length.
Answers
Answer:
And the answer may be 3/8 and 11/8 (among an infinite amount of different rational numbers less than 188 of the actual side length), as shwon below.
Explanation:
1) Calculate the side length of the bulletin board in the shape of a square:
The area of a square is equal to the square of length of the sides
A = x²
Substitute A = 150 unit²
150 = x²
Extract square root of both sides:
2) Find two rational numbers that are within, this is they are less than, 1/8 of the actual side length:
Since, 12² = 144 and 13² = 169, the square root of 150 is between 12 and 13.
Then, you can pick any two whole numbers less than 13 and multiple them by 1/8.
Remember that multiplying by 1/8 is the same that dividing by 8.
Choose 12 and 11, for instance, and two rational numbers that are less than 1/8 of the actual side length are 12/8 and 11/8.
12/8 can be simplified to 3/2 and 11/8 is in its simplest form.
Thus, two rational numbers that are within 1/8 of the actual side length of the bulletin board are 3/2 and 11/8.

Answer:
we know the trapezoids are similar, so that means all sides are at a ratio, thus
that means from the model to actual, the scale is 1:12, so the large side is 12 times as large.
so for the large trapezoid
EF = 6 * 12 =... 72
EH = 4 * 12 =.. 48
HG = 3 * 12 = ..36
GF = 3 * 12 =...36
72+48+36+36 = 192.

SAT math scores for a particular year are normally distributed with a mean of 510 and a standard deviation of 80.
What is the probability that a randomly selected score is greater than 590? Enter the numerical answer only (no percent sign).
Answers
Using the normal distribution, it is found that there is a 16% probability that a randomly selected score is greater than 590.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 510[/tex] and [tex]\sigma = 80[/tex].
The probability that a randomly selected score is greater than 590 is one subtracted by the p-value of Z when X = 590, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{590 - 510}{80}[/tex]
Z = 1
Z = 1 has a p-value of 0.84.
1 - 0.84 = 0.16.
0.16 = 16% probability that a randomly selected score is greater than 590.

Kerri takes out a mortgage for $55,000 at 9% for 25 years. What are her monthly payment, the total amount paid, and the cost of the mortgage?
Answers
The total amount paid for the mortgage will be $123750 and the cost of the mortgage is $178750.
How to calculate the mortgage?From the information, Kerri takes out a mortgage for $55,000 at 9% for 25 years. The total amount paid will be:
= ($55,000 × 9% × 25)
= $123750
The cost of the mortgage will be:
= $55000 + $123750
= $178750
The monthly payment will be:
= ($55000 + $123750) / 25 years
= $178750/(25 × 12)
= $178750/300
= $595

You spend a $20 per turn on a fair game to win $50 for each win. You lose the first round but win the next two rounds.
What was the net payoff?
$100
-$60
-$30
$40
Answers
The net payoff obtained during the game is $40. Option D is the correct answer.
What is net payoff?The term "net payoff" describes the profit or loss realised from a transaction or operation after deducting all costs, charges, and taxes. It is determined by deducting the total cost of the activity or investment from the total income received. A gain is shown by a positive net reward, whereas a loss is indicated by a negative net payoff.
Given that, each round cost $20, and each win gives $50.
Now, for 3 rounds the total cost is:
$20 x 3 = $60
After winning the two round the win amount is:
$50 x 2 = $100
Now, the net payoff is:
$100 - $60 = $40.
Hence, the net payoff obtained during the game is $40. Option D is the correct answer.

Step-by-step explanation:
A scale model represents a ratio. All sides must be shrunk or increased based on a constant value. In this case the ratio of the model is 1/13 the size of the original giving us a 1:13 ratio. So each side of your scale model must be multiplied by 13 to find the real value of the side.
First convert all units to inches then divide the width of the real windmill by the width of the scale model (both in inches) you will see the answer is 13. Multiply the inch values of all sides of your model by 13 and this gives you the proportional value of each side of the real windmill in relation to the scale model.
