X greater then or equal to -1
Answer: 340 students
Step-by-step explanation:
The number of students walking to school is 119 and this is 35% of the total number of students.
Assume the total number is denoted by "x".
That would mean that the following formula captures the situation:
119 = 35% * x
119 = 0.35x
x = 119/ 0.35
= 340 students
Consider c as the cost of the widget so that our given equation is
c = 0.1w^2 + 20w
Take the derivate of the equation.
d/dt (c = 0.1w^2 + 20w)
dc/dt = 0.2w + 20
Given dc/dt = $16000 per month, the number of widgets would contain:
16000 = 0.2w + 20
-0.2w = 20 - 16000
-0.2w = -15980
w = 79900 widgets
Answer:
40,320
Step-by-step explanation:
The first object in the arrangement can be chosen 8 ways. The second, 7 ways (after the first one is chosen). And so on down to the last object, which will be the only remaining one. Altogether, the number of ways you can arrange the objects is ...
8·7·6·5·4·3·2·1 = 8! = 40,320
