Your Assignment
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. What is the area of the actual electronics board?

The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1). Name the vertices of P'Q'R' after a reflection over the x-axis.
Answer:
The coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)
Step-by-step explanation:
We are given:
The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1).
We need to:
Name the vertices of P'Q'R' after a reflection over the x-axis.
Reflection over the x-axis
The rule used for reflection over x-axis
P(x,y)= P'(x,-y)
The coordinates of x-axis remains same, while coordinates of y-axis become negative.
Now, finding coordinates of P'Q'R'
P (2,-8) -> P' (2,8)
Q(1,-4) -> Q' (1,4)
R(4,-1) -> R'(4,1)
So, the coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)

Answer:
11
Step-by-step explanation:
Pulg in 2 into the equation x+3^2
I dont know if theres supposed to be a parenthese like [tex](x+3)^{2}[/tex] but if there isn't then it would be 2+[tex]3^{2}[/tex] which is 2+9
if there is parenthese... it would be:
[tex](2+3)^{2}[/tex] = [tex](5)^{2}[/tex]=25

Step-by-step explanation:
Warren is on vacation and needs to arrange transportation. A rental car costs 60 dollars per day plus a one-time cost of 14 dollars for insurance. Construct a function C(x) that gives the total cost of renting a car for x days.
C(x) = ______________
If Warren has budgeted 434 dollars for the rental, how many days can he afford?
Answer:
The answer is C(x) = 60x + 14 and the answer to the second one is 7 days.
Step-by-step explanation:
C(x) =60x + 14
434 = 60x + 14
-14 -14
420 = 60x
/60 /60
7 = x
or
x = 7 days

PLEASE HELP I NEED THIS ANSWER
Answer:
E
Step-by-step explanation:
Since the value of x is 10 and the value of y is -2, we can plug it into the equation for E. -2 = -1/5(10) which makes it -2=-2 which is true.
Step-by-step explanation:
For every 10 units across (0 to 10),
the line decreases by 2 units (0 to -2).
Slope of line
= Rise / Run = (-2) / (10) = -1/5.
Also the y-intercept of the line is 0
as it passes through the origin.
Hence the equation is y = -1/5 x. (E)

Answer:
She will have to pay back the principal amount of $28,000 plus $728.00 in interest for a total of $28,728.00
Step-by-step explanation:
Interest = principal x interest rate x time period
Interest = 28,000 x .013 x 2
Interest = $728
Total payback amount = principal + interest
Total payback amount = 28000 + 728
Total payback amount = $28,728.00

y = - x + 4 y = 2x - 8
Answer:
{y,x} = {0,4}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = 2x - 8
// Plug this in for variable y in equation [1]
[1] (2x-8) + x = 4
[1] 3x = 12
// Solve equation [1] for the variable x
[1] 3x = 12
[1] x = 4
// By now we know this much :
y = 2x-8
x = 4
// Use the x value to solve for y
y = 2(4)-8 = 0
Find the value of x.

Suppose you saved $300 dollars from a summer job. If school starts September 1, can you afford a cell phone data plan of $29.95 per month for the next year(until next September 1)?
Answer:
No
Step-by-step explanation:
Given that:
Amount saved = $300
Monthly data cost = $29.95
Number of monthly data that can be done from saving :
= amount saved / monthly data cost
= $300 / $29.95
= 10.016694
Hence, saving can only last for 10 months of data subscription.
Hence it can't last till September 1, if the following year, which is about 12 months
Last One, I'd really appreciate it!
Answer:
n = 20
Step-by-step explanation:
Since the triangles are similar, we can create a common proportion.
[tex]\frac{15}{12} =\frac{n}{16}[/tex]
Now you have to solve this proportion
Start by cross multiplying, and you get 12n = 240
Divide both sides by 12, and you get n = 20.
Hope this helped
Hey there!
The answer to your question is n = 20
Since they are similar, we can use proportions:
12/15 = 16/n
Then we can use cross products:
15 x 16 = 12n
140 = 12n
20 = n

round 25395 nearest hundred
Answer:
25,400
Step-by-step explanation:
round the three in the hundreds place up since to the right there is a 9
Hey there!
The answer to your question is 25,400
To round to the nearest hundred, you would be rounding the last three numbers, since that represents a "hundred". So, we look at those numbers, and we see what hundred it is closer to. "395" is closer to 400 than 200, so your answer would be 25,400.
Hope it helps! Have a great day, and good luck!
