Answer:
I need help with this one too!
Step-by-step explanation:
The answer is 12,662 books in the math section.
Since the science section represents 1/3 of the total books, divide 75,972 by 3.
75,972 ÷ 3 = 25,324 books in the science section.
Now, subtract 25,324 science books from the total number of books.
75,972 - 25,324 = 50,648 remaining books.
Divide the remaining books by 4 and then multiply by 3.
50,648 ÷ 4 = 12,662 • 3 = 37,986 business books.
Add the science books and business books together.
25,324 + 37,986 = 63,310 science and business books.
Subtract 63,310 from 75,972.
75,972 - 63,310 = 12,662 books in the math section.
Hope I helped!
Just add them all up that’s it and you will get 20
Answer:
See explanation!
Step-by-step explanation:
<u>We are given a graph that shows the</u><u> value (in dollars) </u><u>of a car stereo at </u><u>time t (in years)</u><u> the time t=0 represents when the stereo was purchased.</u>
<u>A. What does the y-intercept mean in terms of the problem? Include the time and the value of the stereo in your answer.</u>
The graph given shows an exponential expression with a y-interept at
dollars.<em> </em>
<em>This denotes that the initial value of a car stereo at year 0 (i.e. when it first entered the market) was at 300 dollars. </em>
<em />
<u>B. What does V(5)=98 mean in terms of the problem?</u>
Looking at the graph for 
, we know that we are looking at a point 
equal to 
.
This denotes that at year 
, the car stereo value was 
dollars. Thus since the stereo entered the market the value of the car stereo has decreased by over ≈ 202 dollars.
<u>C. Is the graph increasing or decreasing? What does this mean in terms of the problem? </u>
The graph is Exponentially Decreasing suggesting that as the year 
increase, the value of the car stereo is quickly decreasing by larger amounts and not in a linear manner (i.e. the value does not decrease by the same amount every year).
Answer:
73
Step-by-step explanation:
250 - 200 + 38 - 15 = 73
