hari purchased a camera for rs 1560 and sold ot at 5% loss. find hos loss amount
Answer:
[tex]SP = 1482[/tex]
Step-by-step explanation:
Given
[tex]CP = Rs. 1560[/tex] --- Cost Price
[tex]Loss = 5\%[/tex]
Required
Determine the selling price (SP)
This is calculated using:
[tex]\%Loss =\frac{CP - SP}{CP} * 100\%[/tex]
So, we have:
[tex]5\% = \frac{1560 - SP}{1560} * 100\%[/tex]
[tex]5 = \frac{1560 - SP}{1560} * 100[/tex]
Multiply through by 1560
[tex]1560 * 5 = \frac{1560 - SP}{1560} * 100*1560[/tex]
[tex]1560 * 5 = (1560 - SP) * 100[/tex]
[tex]1560 * 5 = 1560 * 100- SP * 100[/tex]
[tex]7800 = 156000- 100SP[/tex]
Collect Like Terms
[tex]100SP= 156000- 7800[/tex]
[tex]100SP= 148200[/tex]
Make SP the subject
[tex]SP = \frac{148200}{100}[/tex]
[tex]SP = 1482[/tex]
The selling price is Rs. 1482
Which of the following is equivalent to the complex number i^34 ?
Choose 1 answer:
А
1
B I
C
-1
D
-I
Given:
The complex number is [tex]i^{34}[/tex].
To find:
The value of given complex number.
Solution:
We have,
[tex]i^{34}[/tex]
It can be written as
[tex]i^{34}=i^{32+2}[/tex]
Using properties of exponents, we get
[tex]i^{34}=i^{32}i^{2}[/tex] [tex][\because a^{m+n}=a^ma^n][/tex]
[tex]i^{34}=i^{4\times 8}i^{2}[/tex]
[tex]i^{34}=(i^4)^8i^{2}[/tex] [tex][\because (a^{m})^n=a^{mn}][/tex]
We know that, [tex]i^4=1,i^2=-1[/tex].
[tex]i^{34}=(1)^8(-1)[/tex]
[tex]i^{34}=(1)(-1)[/tex]
[tex]i^{34}=-1[/tex]
The value of [tex]i^{34}[/tex] is -1. Therefore, the correct option is C.

Answer:
a = 15/28
Step-by-step explanation:
As long as the bases are the same, in this case 2, keep the base and add the exponents when multiplying
keep the base and subtract the exponents when dividing
1/4 + 3/7 = 3/28 + 12/28 = 15/28
A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solution?
Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50
Answer:
50 grams

Jane corporation produces model toy cars each sells for $29 99 sense its variable cost per unit is $14 25 sense what is the break even point for Jane corporation assuming it has a fixed cost of $314800
Answer:
Break-even point in units= 20,000
Step-by-step explanation:
Giving the following information:
Selling price per unit= $29.99
Unitary variable cost= $14.25
Fixed costs= $314,800
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 314,800 / (29.99 - 14.25)
Break-even point in units= 20,000

Answer:
D. 15Step-by-step explanation:
First find the value of x:
3x - 16 + 6x + 7 = 180 (supplementary angles)9x = 189x = 21Find the value of y:
11y - 32 = 6x + 7 (vertical angles)11y - 32 = 6*21 + 711y = 32 + 13311y = 165y = 165/11y = 15Correct choice is D
Find the measure of angle x in the figure.
Answer:
x = 124°
Step-by-step explanation:
The polygon given is a 7-sided polygon with 7 interior angles.
Sum of all 7 interior angles of the polygon = (n - 2)*180, where n = 7, we would have the following equation:
131° + 131° + 126° + 118° + 134° + 136° + x° = (7 - 2)*180
776 + x = 900
Subtract 776 from each side
x = 900 - 776
x = 124°
Answer: 123
Step-by-step explanation:
The equation: (n-2)180
