Write the slope intercept form of the equation of the line through the given points and slope 1,1 and slope of -3/5

Answers

Answer 1
Answer:

Slope is already given in the question so we only need to solve for the y-intercept.

Slope intercept form: y = mx + b

m = slope

b = y-intercept

-3/5 = -0.6

1 = -0.6(1) + b

1 = -0.6 + b

1 + 0.6 = -0.6 + b + 0.6

1.6 = b

Now, write in slope-intercept form.

y = -3/5x - 1.6

Answers

The 60$ system had a greater percentage decrease because it was a lower number to begin with. Taking the same portion out of two different numbers will always be a greater decrease for the lower number.

Five girls participated ina race. Maria finished
before Sarah, but behind
Ella. Marianne finished
before Julia, but behind
Sarah. In what order did
the girls finish the race?​

Answers

Answer:

Ella ............> Maria .............> Sarah ............> Marianne .............> Julia

Explanation:

1- For the first given:

Maria finished before Sarah, but behind Ella

So, we can infer that:

Ella finished first, followed by Maria and then Sarah

Ella ............> Maria .............> Sarah

2- For the second given:

Marianne finished before Julia, but behind Sarah

So, we can infer that:

Sarah finished first, followed by Marianne and then Julia

Sarah ............> Marianne .............> Julia

3- Combining the above parts:

By combining what we got from parts 1 and 2, we can deduce that:

Ella finished first, followed by Maria, Sarah, Marianne and finally Julia

Ella ............> Maria .............> Sarah ............> Marianne .............> Julia

How to make 9 2/5 into a improper fraction and plz show your work because my brain is not that smart

Answers

Answer:

47/5

Step-by-step explanation:

First step: multiply the denominator (bottom of the fraction) of the fraction by the whole number.

5*9 = 45

Second Step: add the numerator

45 + 2 = 47

Third step: Put the result over the denominator.

A cube with 3-inch edges is to be constructed from 27 smaller cubes with 1-inch edges. Twenty-one of the cubes are colored red and 6 are colored white. If the 3-inch cube is constructed to have the smallest possible white surface area showing, what fraction of the surface area is white?

Answers

The fraction of the surfacearea that is white is 2/9.

What is a cube?

It is a polygon having six faces.

The volume of a cube is Side³.

We have,

Cube:

Volume = Side³
Side = 3 inch

Volume = 3³ = 27 inches³

Now,

Redcubes = 21

White cubes = 6

Now,

The total surfacearea of the cube.

= 6 x side²

= 6 x 3²

= 6 x 9

= 54 inches²

Now,

27 cubes make the total surface area 54 inches².

27 cubes = 54 inches²

Multiply 6/27 on both sides.

6 white cubes = 6/27 x 54

6 white cubes = 12 inches²

Now,

White surfacearea = 12/54 inches²

12/54 = 2/9

Thus,

2/9 fraction of the surfacearea is white.

#SPJ2
The volume of the larger cube is 3*3*3, which is 27.
The volume of the smaller cubes is 1*1*1, which is 1.
27/1=27
That means all cubes will be used, so only the placement of the cubes matter.
The center of the cube will show no sides,
The center of the face will show 1 side, which has a surface area of 1sq.in.
Since there are 6 white cubes and 6 faces with 6 face centers, and only one cube center, there will be 5 cubes on the center of the faces and 1 in the cube center.

This means there will be 0 faces of 1 cube and 1 faces shown for the rest of the cubes. Since each face is 1sq.un., the rest is math

(0*1)+((1*1)5)
(0)+(1*5)
0+5
5sq.un. of the cube is white.

a=The fraction of surface area showing
b=Surface area of large cube

b=3*3*number of sides on cube(6)

5*a=b
5*a=54
a=54/5

Your answer is 54/5.
