Answer: 60.13 USD
Step-by-step explanation: 0.859 x 70 = 60.13
Answer: 3.50
Step-by-step explanation:
First take away what he just earned 15-8=7
And since he spent half of his money already you divide 7 divided by 2 =$3.50
And that's your answer!
Answer:
2/3
Step-by-step explanation:
parallel lines have the same slope
given that a line has a slope of 2/3
a line that is parallel to this line would also have a slope of 2/3
<span>In this problem,think of it this way. 1 is to 22 as 1.6 is to X.
When you solve for X you will have the height of your school
all you need to do is multiply 1.6 by 22 and you've got it!
Cheers!</span>
Answer:
Option D
The domain of the function is: {4, 7}
Step-by-step explanation:
We know that for polynomial functions like 
its domain and its rank are all real numbers. However, for this case we are told that the function range is: the set {25, 64}
This means that the function is bounded.
Then the domain of f(k) are all possible values of k such that f(k) belongs to the interval {25, 64}.
To find the limit values of k then we do f(k) = 25
Now we factor the expression:
Then k = 4 and k = -6.
Now we do f(k) = 64
We factor the expression:
k = -9 and k = 7.
Finally we search between the options given an interval that matches.
The option that matches is option D {4, 7}
