Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board. Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area. Adam says he knows another way. Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board. 1. What is the area of the board shown on the scale drawing? Explain how you found the area. Write your answer in the space below. 2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason. Write your answer in the space below. 3.

Answer:
1. Area is 1800 cm. I found this out by multiplying 36 and 50 together.
2. He can figure out that the scale factor 5:1 means that 1 cm in the drawing is 0.2 cm in reality, so he would take 36 and 50 and multiply them both by 0.2 cm then add them to get 17.2, which is the actual area of the rectangle.
3. Actual area is 17.2

Answers
10+ (-4)-(-6) = 12
-8(-7-3) = 80
3-9+2(-9+4) = -16
12-{15+(-3)} / 6-8 = -9
15- 5{-(-5)} = 15
Answer:
1) 22
2)12
3)-80
4)-16
5)-10.5
6)-10
Step-by-step explanation:
-12x + 2y when x = -2 and y = -1
= -12 (-2) + 2 (-1)
= 24 + (-2)
= 22
10 + a - b when a = -4 and b = -6
= 10 + (-4) - (-6)
= 10 - 4 + 6
= 10 + 2
= 12
8(n-3) when n = -7
= 8 (- 7 - 3)
= - 56 - 24
= - 80
3 - x + 2(-x + 4) when x = 9
= 3 - 9 + 2 (- 9 + 4)
= - 6 - 18 + 8
= - 24 + 8
= - 16
12 - (15 + y) / 6 - 8 when y = -3
= 12 - 15 + 3 / 6 - 8
= 12 - 15 + 0.5 - 8
= - 3 - 7.5
= - 10.5
15 - a(-b) when a = 5 and b = -5
= 15 - 5 (5)
= 15 - 25
= - 10

Answer:27
Step-by-step explanation:
3x 11 is 33 and 3 x 5 is 15 then you would do 1 x 2 which is 2 then you would add 2 to 33 which is 35 then subtract 15 which is 20 then add 7 to get 27
Answer:
27
Step-by-step explanation:
First, you do what is inside the parantheses, so 11 - 5 is 6, then you multiply 1 x 2 = 2, and 3 x 6 is 18. Lastly, you add it all up and get the sum of 27. Hope this helps!

Step-by-step explanation:
Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
If Salesman A has exactly
sales, he will reach his maximum weekly commission.
Answers
If we take the paycheck amount of $1020 and subtract it by the weekly salary of $300.
$1020 - $300 = $720
We get $720 in sale commissions. So to get the number of sales, you divide the $720 by the $40 per sale commission.
$720/$40 = 18
Therefore, the sales Salesman B has for the week is 18.
Answer:
20
Step-by-step explanation:
If salesman A works solely on commision and makes $65/sale with a limit of $1,300, you need to divide 1,300 by 65.
Therefore, your answer is 20.

When working with interest, how many decimal places should you have when working with money?
2 decimal places because we're working with money
No decimal places; always round to the nearest dollar.
1 decimal place
Answers
Answer:
I'm pretty sure it's 4 decimal places but that's not one of your answers so I don't know.
Step-by-step explanation:
9514 1404 393
Answer:
more significant figures than in the answer
interest is reported to 2 decimal places when working with money
Step-by-step explanation:
Sums of money can involve large numbers of significant figures. A billion dollars, accurate to the penny, has 12 significant digits. Everyday finance may not involve billions of dollars, but measures of world economic activity may involve substantially more.
In general, if you want interest rate calculations accurate to the penny, the number of significant digits in the interest rate used must match or exceed the number of significant digits in the end result of the computation.
A million-dollar loan may have payments in the $10,000 range or higher, requiring 7 or 8 significant digits to express the payment value. Hence its computation should be made using interest rates accurate to 7 or 8 significant figures.
__
Example:
$1,800,000 loan for 15 years at 3.2% interest. The monthly payment is given by ...
A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . for principal P at rate r for t years
The payment is expected to be in the $10,000 range, so will have 7 significant figures. If we round the monthly interest rate to 7 decimal places, we get ...
A = 1.8×10^6(0.0026667)/(1 -(1.0026667^-180)) = 12,604.38
If we round the monthly interest rate to 8 significant figures, we get ...
A = 1.8×10^6(0.0026666667)/(1 -(1.0026666667^-180)) = 12,604.34
Notice there is a difference in the last digit of the payment value. We should also note here that there was no rounding at any point in the calculation until the final answer.
__
Money amounts are generally rounded to the nearest penny when reported on statements of account. That is, interest amounts are rounded, and the account value is maintained to two decimal places. Because of this, payment-by-payment loan amortization schedules may differ from the calculated values arrived at using formulas such as the one above.
For tax purposes, the amount of tax due may be maintained to a number of decimal digits greater than those that appear on the pay stub. A pay-period tax due of 5.3333, for example, may be charged as 5.33 for two pay periods and 5.34 for the third pay period. The idea is to make the yearly total come out right. Usually, 4 or 5 decimal places will be sufficient for this purpose.
_____
The short answer is ...
enough significant digits to ensure appropriate accuracy of the computed result
(for penny-accurate computations in the trillion-dollar range, 18 significant digits or more may be required.)
interest will be reported to 2 decimal places when working with money
