Answer:
--- the equation of SaveMore company
Step-by-step explanation:
Given
SaveMore
Required
Determine the equation
Let
So, we have:
The equation for the second company is not given. So, the (b) part cannot be correctly answered.
A general solution to the (b) part is:
Assume the equation is:
Next, we equate both
i.e.
This gives:
Collect like terms
Divide by 0.2
<em>Hence, the charges will be the same after 30 texts</em>
Answer:
The second option
Step-by-step explanation:
The second option because it is the one in which if you multiply f4 to the values of x, you would get y.
And that is why it is the second option.
Answer: B-horizontal or vertical stretch
Step-by-step explanation:
Ap3x
You can solve it using an arithmetic sequence.
The nth term of the sequence is equal to the number of penguins in the nth row. It's equal to the number of the row.
There was one penguin in the first row.
The sum of the sequence:
There were 250 penguins - set the sum equal to 250 and solve:
The number of rows can't be a negative number so n≈21.87.
So, there were 21 full rows and one not full.
Calculate the number of penguins in 21 rows:
There were 19 penguins in the last row.
The answer:
There were 22 rows of penguins. The last row wasn't full, it contained 19 penguins.
Let's start out with what we do know:
We have a 5.2L pitcher and 0.4L glasses and we want to know how many glasses we can fill with the 5.2L pitcher of water.
To answer that, we need to divide 5.2L by 0.4L in order to get the number of glasses (the number of 0.4L glasses that can go into a 5.2L pitcher)
So our equation will look like this:
where n = number of glasses
so by doing that division we get:
Notice that the L's cancel out leaving us with a plain number.
So a 5.2L pitcher of water can fill up
13 glasses!
