Jan is saving for a skateboard. She save $30 already which is 20% of the total price. How much does skateboard cost

Find the slope of a line given the following two points: (4, 3) and (5, 2). 1, -1, 2, -2

Mars2501 [29]

The slope formula is y2-y1/ x2-x1 so after plugging it in it would be 2-3/5-4 and you will get your answer.

What is the current density of the solution a/m2

Jlenok [28]

Current density of solution a/m2 is given below

Step-by-step explanation:

Current density is the measure of current generated per unit surface area of electrode.

Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,

CD= Current/(projected area of electrode)

area of rectangle= LxB= 5cm x 2cm =10cm2

CD= 200mA/10cm2

CD= 20mA/cm2

Your Current will be 200mA.

Current density will be 20mA/cm2.

Help please

nika2105 [10]

Answer:

The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Step-by-step explanation:

Consider the provided number line.

From the number line we can observed that:

1) A, B, C and D lies between -1 and 0.

2) Point A and B lies between -1 and -0.5

3) Point C and D lies between -0.5 and 0

Therefore, the value of A and B must have a negative value lying between -1 and -0.5

Also, the value of C and D must have a negative value lying between -0.5 and 0.

Now consider the provided options.

Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16

This is Incorrect representation because the value of A and B should lying between -1 and -0.5.

Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

$A = -0.7\\B = -\displaystyle\frac{9}{16} = -0.5625\\C = -0.4\\D = -\frac{5}{16} = -0.3125$

Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.

Also they are in ascending order from -1 to 0.

Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

A preimage can never be congruent to Which of the following is the notation for a translation that moves a figure 2 units right

DIA [1.3K]

The notation for the translation is (x, y) → (x + 2, y + 2)

<h3>How to determine the translation?</h3>

The translations are given as:

2 units right
2 units up

The above implies that we add 2 to the x coordinate and 2 to the y coordinate.

So, we have:

(x, y) → (x + 2, y + 2)

Hence, the notation for the translation is (x, y) → (x + 2, y + 2)

Which question is a statistical question?

Sidana [21]

Answer: Third option is correct.

Step-by-step explanation:

Statistical questions are those in which we get more than one numerical answer.

According to options,

In option 'A' how many theatres are there in my city, we get only one numerical value instead of collection of data.

In option 'B' how many students like classic movies in my class , in which we get only one numerical value.

In option 'C' how many movies do the students in my class watch in a month.

In this option we would get a collection of data i.e. more than one numerical value.

Because not every student watch same number of movies in a month.

In option 'D' again we get only one numerical value.

Hence, Third option is correct.
