Multiply by the reciprocal. (Flip fraction) so the reciprocal of 3 is 1/3 (because 3= 3/1)

If you multiply a number and its inverse, you get one. To obtain an inverse, you divide 1 by the number. 0 doesn't have an inverse, because you cannot divide by 0.

5 3/8 + 4 1/4 = ? PLEASE HELP QUICK!

malfutka [58]

To solve this question, we first need to convert both of these values into mixed numbers. 5 $\frac{3}{8}$ becomes $\frac{43}{8}$ and 4 $\frac{1}{4}$ becomes $\frac{17}{4}$ . Now we have to find a LCD. An LCD for 4 and 8 is 8, so now we have to change $\frac{17}{4}$ into something over 8. $\frac{17}{4}$ becomes $\frac{34}{8}$ when you multiply the fraction by the form of 1 $\frac{2}{2}$ . 34 + 43 = 77, so our answer is 77/8 which simplifies to 9 $\frac{5}{8}$ .

The side length, s, of a cube is 4x2 3. if v = s3, what is the volume of the cube? 64x6 144x4 108x2 27 64x6 48x4 12x2 1 4x6 36x4

sdas [7]

The volume of the cube given the dimensions of the side length is $64x^{6} + 144x^{4} + 108x^{2} + 27$

<h3>What is the volume of the cube?</h3>

A cube is a 3-dimensional object that has six faces, twelve edges and eight vertices.

Volume of a cube = a³

Where a = length of a side

(4x² + 3) × (4x² + 3) = 16x^4 + 24x² + 9

(16x^4 + 24x² + 9) × (4x² + 3) = $64x^{6} + 144x^{4} + 108x^{2} + 27$

On the last test, 40% of all sudents in Mrs. Well's class got an A. How many students are in this calss if there were 28 A's on

Murljashka [212]

Answer:

70 students

Step-by-step explanation:

If 40% of all students in Mrs. Well's class got an A, and 28 students got an A, that means that 28 = 40%

To find the total number of students, we need to find 100%

40% = 28

Divide by 4

10% = 7

Multiply by 10

100% = 70

So there are 70 students in Mrs. Well's class.

Hope this helps you! :D

Find the slope of the line graph

Tamiku [17]

Answer:

-1

Step-by-step explanation:

the "slope" of a graph is rise / run

you divide the "rise" from one point on a graph to another by the "run" from one point to another.

We can use any two points on a graph to find this value. (There are other ways to find slope, but this is the easiest method for find the slope of a graphed line)

We can see two points on the line already pointed out, but we can also look to see other points (that require less math)

[remember, points are written as (x,y) ]
We can see a point at (1,0) and another point at (0, 1)

the "rise" between two points is the difference in y-values.

0 - 1 = -1

{you can also look at the graph/count the boxes}

So, the rise between these two points is -1.

(really, it's a drop)

the "run" between these two points is the difference in x-values.

1 - 0 = 1

so, the run between these two points is 1.

Now, all that's left to do is divide the rise / run:

-1 / 1 = -1
