John's salary last year was $80000. Last year he got a raise of 10%. This year the company lost money and his salary was cut back to $80000. By what percent did his salary decrease this year?
Answers
Answer:
9.09%
Step-by-step explanation:
John Salary = $80,000.
Raise = 10% of salary = 10/100*80,000=$8000
New Raised Salary = 80000 + 8000 = $88000
Cut back = 80000
Decrease % = (88000-80000)/88000*100
Decrease % = 8000/88000*100
Decrease % = 9.09%

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?
Answers
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

Answers
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.

Let's pretend the sides of a triangle are A B and C.
The third side of a triangle is always greater tham A-B and lesser than A+B. This is called the triangle inequality theorem.
For 7 and 8, we have three lines that come together at one point (adjacent angles), and the vertical angle postulate where two mirrored angles will always have the same angle.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the product of 4 and number a be = P
Let the number to be multiplied be in set A = { 1 , 2 , 3 , 4 , 5 }
Now , the first number = 4
So , the equation will be
The product of 4 and any number a or any number in set A can be written as
a)
The product is P = 4 x a
Product P = 4 x 1
P = 4
It can be written as sum of two equal addends
P = 2 + 2
b)
The product is P = 4 x a
Product P = 4 x 2
P = 8
It can be written as sum of two equal addends
P = 4 + 4
c)
The product is P = 4 x a
Product P = 4 x 3
P = 12
It can be written as sum of two equal addends
P = 6 + 6
d)
The product is P = 4 x a
Product P = 4 x 4
P = 16
It can be written as sum of two equal addends
P = 8 + 8
e)
The product is P = 4 x a
Product P = 4 x 5
P = 20
It can be written as sum of two equal addends
P = 10 + 10
f)
The product is P = 4 x a
Product P = 4 x 6
P = 24
It can be written as sum of two equal addends
P = 12 + 12
Hence , Yes , the product of 4 and any number can always be written as a sum of two equal addends

hari purchased a camera for rs 1560 and sold ot at 5% loss. find hos loss amount
Answers
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
