Answer:

4 books

Step-by-step explanation:

First you add up the lunch and gym clothes together which is 3. Then you subtract 19 (the total of weight she can carry in her bag) by 3 and you get 16. 16 divided by 4 which is the weight of each book gets you 4, the answer.

The total surface area of a cuboid is 112cm^2. find the value of x. values given: 10cm and 2cm.
Tatiana [17]

Answer:

x= 5.6

Step-by-step explanation:

we will need to put the information we currently have into an equation:

10•2•x= 112

then multiply 10•2 which equals 20...then the equation wil turn out like this:

20•x=112

now you will isolate the x... but how?? dividing 20 by itslef.. cancelling it out, and if you do one thing to the other side of the equation, you have to do it to the other...

20/20•x=112/20

you will end up with x= 122/20

you can use a calculator for this step, but  to practice long division... (check the screen shot thingie)

hope this helped !! ^^

Which characteristics describe the scatterplot? Check all that apply.
denpristay [2]

Answer:

1. Negative Correlation

3. Strong Correlation

5. Linear

Step-by-step explanation:

We have been given a scatter-plot. We are asked to choose the characteristics of the given scatter-plot.

Upon looking at our given scatter-plot, we can see that as the values of x are increasing values of y are decreasing.

We know that the relationship between two variables in which one variable increases as the other decreases is known as negative correlation. Therefore, the given scatter-plot represents negative correlation and 1st option is a correct choice.

We can also see that the slope of the line connecting all data points is approximately -1, which represents a strong negative correlation, therefore, 3rd option is correct as well.

If we draw a line on our given scatter-plot, it will connect all the data points. Therefore, the given scatter-plot has a linear correlation and 5th option is correct as well.

An image point has coordinates B'(7, -4). Find the coordinates of its pre-image if the translation used was (x + 4, y + 5).
Vera_Pavlovna [14]

Answer:

B

Step-by-step explanation:

B'(7, -4)

Let the pre-image coordinates be (x,y)

Consider x-coordinate,

x + 4 = 7

x = 3

Consider y-coordinates,

y + 5 = -4

y = -9

pre-image coordinates is (3, -9)
