What Is The Sign Of -xy?

Answers

Answer 1

Answer:

Positive

Step-by-step explanation:

Since x > 0 =  x is positive

Since y < 0 = y is negative

Product of positive and negative number is negative.

Therefore,

       xy = - xy

    - (xy) = -( -xy)

    - (xy) = xy              [since product of negative and negative is positive]

Answer:

perimeter

Step-by-step explanation:

perimeter is the distance around

volume is the amount it will hold

weight is  how heavy it is

area is the amount of space it covers

Answer:

Primeter

Step-by-step explanation:

So Weight is out of the question since you do not need to weigh anything

Area is the inside of the picture so that is also out

It is either primeter or volume

Volume is used to find the surface of an object, it takes up. It is used for 3-d objects, since this is not a 3-d piece it is not that.

It is the primeter since you will need to find out the side legnths to find out what frame will work.

What is ​75% of 16​?

Answers

Answer:

12

Step-by-step explanation:

16 times 0.75 = 12

Answer:

12

Step-by-step explanation:

75%=3/4.

So, we can simplify it to 3/4 of 16

4/4 of 16 is 16.

So, 3/4 of 16 is 1/4 less than that.

1/4 of 16 is 4. We want 3/4 so we multiply 4*3=12

You are using a hose to fill up your backyard swimming pool on a hot day. Water flows out of the hose at a rate of 6 gallons per minute. In the equation below, m is the number of minutes the hose has been running, and g is the number of gallons of water in the pool.
The relationship between these two variables can be expressed by the following equation:
g=6m,
Identify the dependent and independent variables.

Answers

Answer:

The independent variable is the m, which is the number of minutes the hose has been running. The dependent variable is the g, which is the gallons per minute.

Answer:

g=36

Step-by-step explanation:

so if g=6m you would do 6x6 as 6 gallons per minute and g is the amount in the pool so you times them to get 35 so g=36

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1

Answers

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

Answer : -1 < -0.25,

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two functions. The function integer_to_reverse_binary() should return a string of 1's and 0's representing the integer in binary (in reverse).
