It should be 40 percent.
You can think of it as starting with 100 as in 100 dollars or 100 tic tacs
If you take away 25%, you take away 25 tic tacs and now you only have 75.
From your 75, you take away 20% which is equal to 15. 75- 15=60
If you look at the end result of 60, you can see that that is 100 - 40 so 40% of the total was taken off
The <em><u>correct answer </u></em>is:
B. 14
Explanation:
Let x be the number of days. On day 1, we begin with 64 orders. We gain 18 orders per day; this is 18x, and gives us
64+18x.
We also make 28 crates per day, which decreases the number of crates we need by 28 per day; this is -28x, and gives us
64+18x-28x
Combining like terms, we get
64-10x
For day 5, we replace x with 5:
64-10(5) = 64-50 = 14
Answer:
2. a and b only.
Step-by-step explanation:
We can check all of the given conditions to see which is true and which false.
a. f(c)=0 for some c in (-2,2).
According to the intermediate value theorem this must be true, since the extreme values of the function are f(-2)=1 and f(2)=-1, so according to the theorem, there must be one x-value for which f(x)=0 (middle value between the extreme values) if the function is continuous.
b. the graph of f(-x)+x crosses the x-axis on (-2,2)
Let's test this condition, we will substitute x for the given values on the interval so we get:
f(-(-2))+(-2)
f(2)-2
-1-1=-3 lower limit
f(-2)+2
1+2=3 higher limit
according to these results, the graph must cross the x-axis at some point so the graph can move from f(x)=-3 to f(x)=3, so this must be true.
c. f(c)<1 for all c in (-2,2)
even though this might be true for some x-values of of the interval, there are some other points where this might not be the case. You can find one of those situations when finding f(-2)=1, which is a positive value of f(c), so this must be false.
The final answer is then 2. a and b only.
Unit rate would be 50 because 250÷5=50, so the answer would be (250×3)+50, witch is 800.
