The value of x+y/y is an integer when y=4. which of the following is a possible value of x?

prisoha [69]

Assuming that you mean

$\dfrac{x+y}{y}$

if we let $y=4$ , the expression becomes

$\dfrac{x+4}{4}$

This is an integer if and only if x+4 is a multiple of 4, which in turn happens if and only if x is itself a multiple of 4.

So, the only good options are the multiple of 4, in your case -16.

Mary leaves her house to take a walk. The graph shows the distance, d, in feet from her house that Mary is at any given time, t,

Vitek1552 [10]

You haven't provided the graph, therefore, I cannot provide you with a specific solution for this question.
However, I will tell you how to solve it and you can apply on the graph you have.

Now, we are given that:
x-axis represents the distance in ft
y-axis represents the time in minutes

To get the time that she has walked when she reaches the farthest point from her house, all you have to do is:
1- go to the greatest point on the x-axis. This point would be representing the farthest distance.
2- get the value of the y corresponding to the x-point you got in step one. This would be the time walked when she reaches the farthest point which is the value you are looking for.

Hope this helps :)

Lucia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating. At what rate is lucla using energy in calor

navik [9.2K]

we know that

$1\ kilocalories=1,000\ calories\\ 1\ hour=60\ minutes$

1) Convert $\frac{kcal}{h}$ to $\frac{cal}{h}$

$420\frac{kcal}{h}=420*1,000=420,000\frac{cal}{h}$

2) Convert $\frac{cal}{h}$ to $\frac{cal}{min}$

$420,000\frac{cal}{h}=420,000/60=7,000\frac{cal}{min}$

therefore

the answer is

$7,000\frac{cal}{min}$

How many different words can be formed with the letters AAAABBCCD (not necessarily meaningful words)?

Nikitich [7]

Answer:

3780 different words

Step-by-step explanation:

The number of possible words that can be formed by a word with n letters is given by n! (factorial of n), but when we have repeated letters, we need to divide the result by the factorial of each number of repeated letters.

In this case, we have 9 letters, but we have 4 times A, 2 times B and 2 times C, so the formula to calculate the number of different words is:

$number = {9!}/(4!2!2!)$

$number = (9*8*7*6*5*4*3*2)/(4*3*2*2*2)$

$number = 3780\ words$

So we can form 3780 different words.
