Answer:
[tex]2[/tex]
Step-by-step explanation:
Let [tex][n][/tex] denote the area of some polygon [tex]n[/tex].
The sum of the area of quadrilaterals BCDE and MNDE is equal to [tex][ABC]-([MBE]+[NDC]+AMN])[/tex] (big triangle subtracting the three smaller triangles that aren't part of BCDE or MNDE).
Let the area of triangle ABC be [tex]\alpha[/tex].
Triangle AMN is similar to triangle ABC. Because their side lengths are in ratio 1:2 respectively, the ratio of the area of triangle AMN to triangle ABC is [tex]1:2^2=1:4[/tex].
Therefore, [tex]\displaystyle [AMN]=\frac{1}{4}[ABC]=\frac{1}{4}\alpha[/tex].
Now for triangle NDC, NDC is similar to triangle AMC. Since M is the midpoint of AB, AMC is half the area of ABC. The ratio of the side lengths between triangle NDC and triangle AMC is [tex]1:2[/tex] because the D is the midpoint of MC, so it follows the ratio of their areas must be [tex]1:4[/tex], respectively.
Therefore, [tex]\displaystyle[NDC]=\frac{1}{4}[AMC]=\frac{1}{8}[ABC]=\frac{1}{8}\alpha[/tex].
We can use the same concept for triangle MEB. Triangle MEB is similar to triangle ANB, and the ratio of their sides is also [tex]1:2[/tex], since E is the midpoint of BN. Their areas are in the ratio [tex]1:2^2=1:4[/tex] and we have [tex]\displaystyle [MBE]=\frac{1}{4}[ANB]=\frac{1}{8}\alpha[/tex].
Thus,
[tex]\displaystyle \frac{[ABC]}{[BCDE]+[MNDE]}=\frac{\alpha}{\alpha-\frac{1}{4}\alpha-\frac{1}{8}\alpha-\frac{1}{8}\alpha}=\frac{\alpha}{0.5\alpha}=\frac{1}{\frac{1}{2}}=\boxed{2}[/tex]
Sara earns $12.75 per hour at her job. She works 18 hours each week. While at work, she parks her car in a garage that charges $10.50 every 3 hours.
After paying for parking, how much does Sara earn each week?
A.$198.00
B.$229.50
C.$166.50
D.$261.00
Answers
She earns $229.50 each week, since 12.75•18 is 229.50. If the garage charges $10.50 every 3 hours, and she works 18 hours, she would have to pay $63 for parking. 229.50 - 63 = $166.50 each week.
9514 1404 393
Answer:
C. $166.50
Step-by-step explanation:
The rate Sara pays for parking is ...
$10.50/(3 hours) = $3.50 /hour
So, Sara's net pay, after paying for parking, is ...
$12.75/hour - 3.50/hour = $9.25 /hour
If she works 18 hours per week, her net earnings are ...
(18 h)($9.25/h) = $166.50 . . . . weekly earnings

12. Suppose a computer manufacturer has the total cost function C(x) = 65x +3500 and the total revenue function
R(x) = 365x, where x represents the number of computers produced and sold. What is the profit on 326 items?
a. $86,500
b. $101,300
c. $94,300
d. $1,238,800
$143.680
Answers
Cost is 65x + 3500 where x is = 326.
65(326) + 3500
21,190 + 3500 = $24,690 is the cost.
Revenue is 365x where x is 326.
365(326) = $118,990
Now we subtract the two:
118,990 - 24,690 = $94,300
This means that the answer is C) $94,300.

Function or non functional???
Answers
Answer:
The relation is a function.
Step-by-step explanation:
In the given relation, {(A, 8), (B, 8), (D, 5), (F, 5), (G, 8)}:
A relation is a function for which none of the ordered pairs have the same first component and different second components.
In the given relation:
The first component comprises of: {A, B, D, F, G}. The second component comprises of: {8, 8, 5, 5, 8}.The given relation represents a function since none of the first components have the same corresponding second components. In other words, there are no repeating values of A, B, D, F, and G. Each of these values has its own corresponding second component.
Therefore, the relation, {(A, 8), (B, 8), (D, 5), (F, 5), (G, 8)} is a function.

Which employee did not have the same dollar amount in sales for the month of February as the other two employees?
a.

b.
Employee #2
c.
Employee #3
d.
They each had the same dollar amount in sales.
Answers
The employee who did not have the same dollar amount in sales for the month of February as the other two employees is (a) Employee 1.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Earnings of three employees in the month of February are :
Employee 1 = 4.7 = $4700
Employee 2 = 4.9 = $4900
Employee 3 = 4.4 = $4400
Earnings of employee 1 = $2,000 + 3% on all sales
Let the amount of all sales be x.
2000 + (3% x ) = 4700
2000 + 0.03x = 4700
0.03x = 2700
x = 90,000
Earnings of employee 2 = 7% on all sales
Let the amount of all sales be x.
0.07x = 4900
x = $70,000
Earnings of employee 3 = 5% on the first $40,000 + 8% on anything over $40,000
Let the amount of sales be 40,000 + x.
(0.05 × 40,000) + (0.08 x) = 4400
2000 + 0.08x = 4400
0.08x = 2400
x = $30,000
Amount of sales = $40,000 + $30,000 = $70,000
Hence employee 1 did not have the same amount as the other 2 in February.

You are working with a square. All 4 sides are equal
2x+ 1 = 4x - 7 Subtract 2x from both sides
1 = 4x - 2x - 7 Combine
1 = 2x - 7 Add 7 to both sides
1 + 7 = 2x Combine
2x = 8 Divide by 2
2x/2 =8/2
x = 4
The diagonals of a square bisect the 90 degree angle.
7y + 3 = 45 Subtract 3 from both sides
7y = 45 - 3 Combine
7y = 42 Divide by 7
y = 42/7
y = 6
