Answer:
The cafeteria provides three meals per day.
<u>Reason 1</u>
Yes, they vary directly
As number of days increases ,Total number of meals i.e
1st day ⇒ 3
2nd day⇒6
3 rd day⇒9
4th day⇒12
......................
.........................
increases.
Total number of Meals = k×Number of days
But there is another possibility also
<u>Reason 2</u>
1 st day ⇒ 3
2nd day ⇒3
3rd day⇒ 3
.....................
.....................
As you can see from the above expression On each day number of meals is
constant.
So we can say that ,
On each Day=Constant amount of meal=3
So, there is no Proportionality between Days and Meal.
Answer:32
Step-by-step explanation:
24/x = 3/4.....cross multiply and then divide
Answer:
137
Step-by-step explanation:
38 + 48 = 86
86/2 = 43
180 - 43 = 137
Answer:
0
Step-by-step explanation:
First, you need to try to get rid of the ().
To do this:
15 * 3 and 15 * x
This makes 45 and 15x after the = , so the formula is now:
15x + 45 = 45 + 15x
Now get the 15x to the left side. When a number switches sides, it becomes negative when positive and positive when negative. So in this case 15x will become -15x and the 45(on the left) becomes - 45
15x - 15x = 45 - 45
Answer: 0
Answer:
Every day, the mass of the sunfish is multiplied by a factor of <u>[ln(1.34)/6]. </u>
<u></u>
Step-by-step explanation:
You have the following function:
To know what is the factor that multiplies the mass of the sunfish each day, you derivative the function M(t):
![\frac{dM(t)}{dt}=(1.34)^{\frac{t}{6}+4}(\frac{1}{6})ln(1.34)\\\\\frac{dM(t)}{dt}=\frac{ln(1.34)}{6}[(1.43)^{\frac{t}{6}+4}]\\\\\frac{dM(t)}{dt}=\frac{ln(1.34)}{6}M(t)](https://tex.z-dn.net/?f=%5Cfrac%7BdM%28t%29%7D%7Bdt%7D%3D%281.34%29%5E%7B%5Cfrac%7Bt%7D%7B6%7D%2B4%7D%28%5Cfrac%7B1%7D%7B6%7D%29ln%281.34%29%5C%5C%5C%5C%5Cfrac%7BdM%28t%29%7D%7Bdt%7D%3D%5Cfrac%7Bln%281.34%29%7D%7B6%7D%5B%281.43%29%5E%7B%5Cfrac%7Bt%7D%7B6%7D%2B4%7D%5D%5C%5C%5C%5C%5Cfrac%7BdM%28t%29%7D%7Bdt%7D%3D%5Cfrac%7Bln%281.34%29%7D%7B6%7DM%28t%29)
(1)
where you have used the following general derivative:
The derivative give you the increase in the mass per day (because t is days). By the expression (1) you can conclude that each day the mass increase a factor of [ln(1.34)/6].
Every day, the mass of the sunfish is multiplied by a factor of <u>[ln(1.34)/6]. </u>
