Answer:
Estimate = 3400 books
Step-by-step explanation:
Given that:
Books read by students.
Kindergarten 247
First grade 385
Second grade 1347
Third grade 1549
We have to round the each number to nearest hundred.
247 rounded to the nearest hundred is 200.
385 rounded is 400
1347 rounded is 1300
1549 rounded is 1500
Total = 200 + 400 + 1300 + 1500 = 3400
Hence,
Estimate = 3400 books
Answer:
f(x) = x³ − 5x² − 16x + 80
Step-by-step explanation:
The degree is 3, so there are exactly 3 zeros.
The zeros are -4, 4, and 5.
f(x) = (x + 4) (x − 4) (x − 5)
f(x) = (x² − 16) (x − 5)
f(x) = x³ − 5x² − 16x + 80
This is how it would look on a graph.
the proportion you need to find is how many dollars per treat, so you do 3.50 divided by 5, and you get 0.7. then you do 0.7 times 12 and you’ll get $8.40 as your final answer.
hope this helped!!!
