Answer: 420 minutes.
Step-by-step explanation:
The first method could be to do 180 / 3 then multiply that by seven:
180 / 3 = 60
60 * 7 = 420.
That solution would be to find out what 1/7 of her total monthly minutes is, and then multiplying it in order to get the total monthly minutes.
Another solution could be to divide 180 by 3/7:
180 / (3/7) = 420
Answer:
irrational
Step-by-step explanation:
is an irrational number because it is not a perfect square root
hope this helps... -_-
Answer:
see below
Step-by-step explanation:
The parent function is x^2 which is a parabola at vertex (0,0)
g(x) = ( x+3) ^2
y = f(x + C) C > 0 moves it left
So the parabola is shifted to the left 3 units
h(x) = -( x+3) ^2
y = −f(x)
Reflects it about x-axis
Means flip it about the x axis
This the equation you will need to use (the Pythagorean Theorem)

when you put the numbers in for the variables given it will look like this

3 squared equals 9 and 4 squared equals 16:

so side c is 25 units
Answer:
Each balloon costs $1
Each banner costs $2
Step-by-step explanation:
First of all, let's write down the equation from this problem.
Let "y" be the cost of the ballon, and let "x" be the cost of a banner. Then the following is true from the question...
4y + 2x = 8
6y + x = 8
Now since both of them are equal to 8 both of them are equal to each other, and so we can get the following equation...
4y + 2x = 6y + x
2x - x = 6y - 4y
x = 2y
Now if we substitute 2y instead of x in one of the previous equations we will obtain...
6y + x = 8
6y + 2y = 8
8y = 8
y = 1
From the equation x = 2y we know that...
x = 2y
x = 2(1)
x = 2
