Answer:
You bake 21 chocolate chip cookies.
Step-by-step explanation:
Since the ratio of chocolate chip to oatmeal is 7:5, the ratio is now ?:15. You multiplied the number of oatmeal cookies by 3, which means you must now multiply the number of chocolate chip cookies by the same number. 7 times 3 is 21.
Answer:
26*26*25 = 16,900
Step-by-step explanation:
First, we focus on the first initial, we have 26 letters that could fit in (the whole alphabet).
In the last initial we <em>can't</em> have the same we have in the first one, so we have 25 letters (the whole alphabet minus the letter that we already choose in the first initial
).
We have <em>no restrictions</em> for the middle one, so again we have 26 letters that could fit in.
So, we have 26*26*25 combinations (we multiply them because they happen all at the same time)
There is no need to use factorials, but we can use them if you want to.
Let's notice that 26! = 26*25*24*23*22*...
In our calculation, we only need the two first factors, so we can divide by 24! =24*23*22*21*...
Therefore,
26*26*25 = 26 * 26! /24!
Answer: D)600N
Step-by-step explanation:
The question is incomplete, since it is not given the acceleration. However, let's assume the truck's acceleration is .
Now, according to Newton's second law of motion, the force exerted on an object is directly proportional to its mass and acceleration :
Where:
Solving the equation:
Finally:
