NEED HELP ASAP

Answers

Answer:

p = 3/4 or 0.75

Step-by-step explanation:

your equation: 60p = 45

divide both sides by 60: p = 45/60

simply the fraction by dividing the numerator and denominator by 15: p = 3/4

your answer: 3/4 or 0.75

Answer: p = 75%

Step-by-step explanation:

p = 45/60 then divide that by 15/15

so 45 divided by 15 is 3

and 60 divided by 15 is 4

this equals too 3/4 = 0.75

0.75 = 75%

Step-by-step explanation:

If one side of a square is 50 miles, all sides are.

a^2 + b^2 = c^2

You are looking for c.  a and b both equal 50

50^2 + 50^2 = c^2

c^2  = 2500 + 2500

c^2 = 5000

√c^2 = √5000

c = 70.7 miles

One

Again you are using a^2 + b^2 = c^2

c = 169

Perimeter of square 2  = 48

a = ?

a is square 3.b is square 2c is square 1

4s =  48  

s = b = 48/4

s = b = 12

area_2 = s^2

Area_2 =12^2

Area_2 = 144

Area_ 1^2 - Area_2 ^2 = Area_3^2

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 cost of 2 pencils be = A

Now , the equation will be

The cost of 6 pencils is = 36 cents

So ,

The cost of one pencil is = cost of 6 pencils / 6

The cost of one pencil is = 36 / 6

The cost of one pencil is = 6 cents

And , the cost of 2 pencils is calculated by the equation

The cost of two pencils is A = cost of one pencil x 2

The cost of two pencils is A = 6 x 2

The cost of two pencils is A = 12 cents

Therefore , the value of A is 12 cents

Hence , The cost of 2 pencils is 12 cents

Stock prices for a certain company start at $12 per share an increase at a rate of
$2 per month. Write an equation of the function of the value of the stock price v,
as a function of the number of month that have passed, m.

Answers

Step-by-step explanation:

V = $12

M = The number of months

So, function = v + $2m

Lets take an Example = for example the stock price now is $20

V + $2m = $20

V = $12

So, 12 + $2m = 20

$2m = 20 - 12

$2m = 8

m = 8/2

m = 4

So this used we can easily find the number of months

Now let's try with the stock price only

The total now is $24

And 6 months passed

v + $2m = $24

v + $2(6) = $24

v + $12 = $24

v = $24 - $12

v = $12

So we got the same stock price

We found with this function the stock price as well as the number of months
