Answer:
A
Step-by-step explanation:
The function is f(x) = 15x + 25 as 25$ is a fixed rate ( it does not change and is always charged) when 15$ for any other service which can be anything, a costumer can have 0 services other than the hair cut which gives f(0). As for the question, it's asking for haircut, shampoo, highlight, and blow dry so that is 3 other services other than the fixed haircut which means f(3). substitute x=3 in the function to get 15(3) + 25 = 45+25 = 70.
First lets get the total weight that Hailey bought, that is working with fractions:
1 3/7 = 7/7 + 3/7
= 10/7 = 1.43
so we use a rule of three to solve this:
1.43 kg ------> $13
1 kg --------> x
x = (1)(13)/(1.43)
x = 9.09
therefore a 1kg of sliced salami costs $9.09
No, the height wouldn't be 70 feet, it would be 80 feet.
You would get this answer by using the equation h= A/b (h meaning height)
A = area ( or 20,000)
b= base ( or 250)
Then you divide A by b:
20,000/ 250 =
80
I hoped this helped! :)
Answer:
the answer is A because it's pace at the y axis
Think about the rule when multiplying powers together.
When multiplying two powers that have the
same base, simply add their exponents.
In this problem, each power has a base
of <em>a</em> and our exponents are <em>m </em>and <em>n</em>.
So adding these exponents together, we have a^m + n.
