Answer:
33.33%
Step-by-step explanation:
We need to calculate the unit selling price and cost of each cosmetics.
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;
x = 1 cosmetic
since 360 = 12 cosmetic
cross multiply
12x = 360
x = 360/12
x = 30
Hence the unit cost price of the cosmetics will be Rs. 30
Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)
Selling price per unit = Rs. 40
Cost price per unit = Rs. 30
percent gain = SP-CP/CP * 100%
percent gain = 40-30/30 * 100
percent gain = 10/30 * 100
percent gain = 100/3
percent gain = 33.33%
Hence the percentage gain is 33.33%

As per the given information: quadrilateral ABCD is a parallelogram.
[tex] m\angle B + m\angle DCB =180\degree \\[/tex]
(adjacent angles of a parallelogram)
[tex] 110\degree + m\angle DCB =180\degree \\
m\angle DCB =180\degree - 110\degree \\
m\angle DCB =70\degree\\
m\angle DCG=\frac{1}{2} m\angle DCB \\(\because GC \: bisects \: \angle DCB) \\
m\angle DCF=\frac{1}{2}\times 70\degree... (\because C-G-F) \\
m\angle DCF=35\degree\\
m\angle BFC = m\angle DCF = 35\degree\\ (Alternate \: \angle s) \\\\
m\angle BFC + m\angle CFA = 180\degree\\ (straight \: line \: \angle s) \\\\
35\degree + m\angle CFA= 180\degree\\
m\angle CFA = 180\degree-35\degree \\\\
m\angle CFA= 145\degree \\\\
\huge\purple {\therefore m\angle GFA = 145\degree} \\(\because C-G-F) \\[/tex]

Mallie's car dealership expects to sell 18 cars every 6 days. Based on this information, how many days does the dealership expect that it will take to sell 90 cars
Answer:
30 days
Step-by-step explanation:
1 way:
18 cars/6 days = 3 cars/1 day
90cars/3 cars a day= 30 days
another way:
90 cars/18 cars= 5
6 days * 5= 30 days

Is ABC is similar to DEF?
Answer:
Yes
Step-by-step explanation:
yes
They both have interior angles of 90-51-39, which automatically makes them similar. You could also see the dilation factor of .75 based on the 2 sides of a right angle to prove it.
ΔABC and ΔDEF are similar by AA Similarity Theorem.
Given in the question,
In ΔABC,
m∠A = 51°AB = 8 unitsBC = 10 unitsIn ΔDEF,
m∠F = 39°EF = 7.5 unitsTo prove these right triangles similar, we can use AA-Similarity Theorem,
By applying triangle sum theorem in ΔDEF,
m∠D + m∠E + m∠F = 180°
m∠D + 90° + 39° = 180°
m∠D = 51°
Hence, ∠D ≅ ∠A and ∠E ≅ ∠B
Therefore, ΔABC ~ ΔDEF [By AA Similarity Theorem]

A+b=30, a-b=20, a/b=?
Answer:
5
Step-by-step explanation:
a+b=30
a=30-b------1
&a-b=20
a=20+b-----2
From eqn 1 and 2, we get
30-b=20+b
or, 10=2b
b=5
Now, a=20+5
a=25
Therefore, a/b=25/5
=5
Using a system of equation, the value of a/b obtained from the values of a and b calculated is 5
The system of equations:
a + b = 30 - - - (1)a - b = 20 - - - (2)From (1) :
a = 30 - b - - - (3)
Substituting a = 30 - b into (2)
30 - b - b = 20
30 - 2b = 20
30 - 20 = 2b
10 = 2b
b = 5
From (3) :
a = 30 - 5
a = 25
Hence,
a/b = 25 / 5 = 5
Hence, the value of a/b is 5

You currently make $18.32 an hour, get time and a half for anything over 40 hours, and a 10% commission on
all sales for the month. Determine your gross monthly salary given that your sales on average are $7,891 per
month and you work 5 hours of overtime a week.
a. $4,011.78
b. $4,132.95
C. $4,269.90
d. $4,320.12
Answer: b
Step-by-step explanation:
The correct answer is:
C) $4269.90.
Explanation:
40 hours per week at 18.32:
40*18.32 = 732.80.
Over time is time and a half; this means:
18.32*1.5=27.48 per hour overtime.
5 hours of overtime per week would be:
27.48*5=137.40.
Together this makes:
732.80+137.40=870.20 per week.
There are 4 weeks in a month;
4*870.20=3480.80.
You make 10% commission on the sales; 10% = 0.1.
0.1*7891=789.10.
Add this to the monthly income:
3480.80+789.10=4269.90.
