45 =p x 60
NEED HELP ASAP
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%

What is the sum of -9 and -18?
Answer: The answer to the question you asked up top would be -27, however the question in the picture doesn't match. As for the question in the picture, the answer is should be choice B or 4 square root 2i
Step-by-step explanation:
The first one: add the number together since they are both negative and just place a negative sign in front.
The second one: break down the square root of -18 into 9*-2. Then add [tex]\sqrt{-2} + 3 \sqrt{-2}[/tex] which equals [tex]4\sqrt{2}i[/tex]

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.
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

Find the missing side length of this right triangle
Answer:
Choice A.
Step-by-step explanation:
Since this is a right triangle, we can use Pythagorean Theorem to solve for the missing side length.
3² + x² = 8²
9 + x² = 64
x² = 55
x = √55
Therefore, the answer is choice A.

Answer:
Area_3 = 25
Distance from Washington to Springfield = 70.7 miles
Step-by-step explanation:
Two
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 14s = 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
169 - 144 = Area_3^2
side_3 = sqrt(25)
area= 25

How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

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

The endpoints of the diameter of a circle have the coordinates (3,8) and (9,16) .
What are the coordinates of the center of the circle?
9514 1404 393
Answer:
(6, 12)
Step-by-step explanation:
The center of the circle is the midpoint of the diameter, the average of the end point coordinates:
((3, 8) +(9, 16))/2 = (3+9, 8+16)/2 = (12, 24)/2 = (6, 12)
The center of the circle is (6, 12).
