How to increase a number by a percentage?

Number = n 
percentage = p, in decimal, e.g. 50% = 0.5, 120% = 1.2

10 increased by 50% = n+n*p
= 10 + (10*.5)
=15

n+ (n*p) = number increased by percentage of that number

Any number can be increased if the percentage is more than 100%
for instance
120% of 10
120*10/100 =12
here the number 10 is increased to 12

Given g(x) = -x + 5, solve for x when g(x) = 3.
Elan Coil [88]
Both equal g(x) so put them together

-x+5=3 then solve for x

-x=3-5
-x=-2
-2 divided by -x =2

x=2

Andy has a collection of movie dvds. in andys collection 3/5 of the dvds are action 1/4 of the dvds are comedy. andy said that 4
Lerok [7]
If 3/5 are action and 1/4 are comedy then:

(3/5)+(1/4) are action or comedy

To add/subtract fractions you need a common denominator...

(3/5)*(4/4)+(1/4)(5/5)

(12/20)+(5/20)

17/20

So 17/20 (85%) of his collection are action or comedy not 4/9...

Please help me solveeeee
elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

I think the only way you can solve this is to assume that <R means PRT in the given ratio. If I am wrong, I don't think the problem can be solved.

Find <T

Let <T = x

and <PRT = 3x

KLMN is a Parallelagram and therefore two adjacent angles are supplementary.

<PRT + <T = 180 degress

3x + x = 180 degrees

4x = 180

x = 45

So <T = 45

<PRT = 3*45 = 135

If RD is perpendicular to PS then <PDR = 90o

Here's the trick.

RD is also Perpendicular to RT

<MRD + <MRT = 90

<MRT = 180 - 90 - <T

<MRT = 180 - 90 - 45

<MRT = 45

Here comes your answer

=================

<MRD + MRT = 90

<MRD + 45 = 90

<MRD = 45

====================

Note: you must ignore everything to do with the diagram. It is not drawn to scale and the letters are not the same as in the question. The only thing you use is that the figure is a ||gm

Which expressions are monomials?
Nimfa-mama [501]

Monomials are the expressions with one terms.

A.) -4+6 = 2

Since, it has only one term. Therefore, it is a monomial.


B.) b+2b+2 = 3b+2

Since, it has two terms. Therefore, it is not a monomial.


C.) (x-2x)^2 = (-x)^2=x^2

Since, it has only one term. Therefore, it is a monomial.


D.) \frac{rs}{2}

Since, it has only one term. Therefore, it is a monomial.


E.) 36x^2yz^3

Since, it has only one term. Therefore, it is a monomial.


F.) a^x

Since, the variable is in the power. So it is not a monomial.


G.) x^\frac{1}{3}

Since, the power is not a integer. Therefore, it is not a monomial.
