Step-by-step explanation:

% change = (new - original)/original × 100

= (8,000 - 5,000)/5,000 × 100

= 3,000/5000 × 100

= 60%

Answer:

126:54, or

63:27,or

7:3

Step-by-step explanation:

we can see that 126 can be divided by 2, and so can 54, so we reduce to #2,

we can see #2 can be divided by 9, so we get to #3

Answer:

Rewriting the equation in slope intercept form is: Y= -8x+4

Step-by-step explanation:

Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.

First of all, we know that our slope is -8... so we have y= -8x so far

From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.

To wrap things up, the slope is -8 and the y intercept is 4.

We then get Y= -8x+4

Hope this helps! :)

hi

3x+y +2 = 0   so   y = -3x-2

parrallel  line has the same slope , so  is  -3x

then  :     -3 (3) +c  = -4

               -9 +c = -4

                 c = -4 +9

                 c = 5

so parallel is   : y=   -3x +5

Answer:

Hi there!

Your answer is:

Estimated to 60.38$

Step-by-step explanation:

7.5 hrs yesterday

8.05$ per hour

7.5hrs * 8.05dollars per hour = 60.375$

Estimated to 60.38$

Answer:

20 minutes

Step-by-step explanation:

The question can be shown like so, 1.5+0.6x

Since the total charge was 13.5, you can write an equation

13.5=1.5+0.6x

Simplify using property of subtraction

13.5 - 1.5= 1.5 - 1.5 + 0.6x

12 = 0.6x

Simplify using property of division

12/0.6= 0.6x/0.6

x=20

Answer:

y=28/3x+6

Step-by-step explanation:

If you use the slope formula,     y2-y1

                                                      _____\

                                                       x2-x1

You would get that the slope is 23/3 and you can see the y-intercept is 6 so you would get y=28/3x+6.

Hope this helps:)

Answer:

6.8127 *10^16

Step-by-step explanation:

Scientific notation is a way to make these numbers easier to work with. In scientific notation, you move the decimal place until you have a number between 1 and 10. Then you add a power of ten that tells how many places you moved the decimal.

Answer: two points

Step-by-step explanation:

The intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

The intersection of a circle and a regular hexagon.

As we know, the polygon is a geometric figure with a finite number of sides in two dimensions.

On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

If the circle and regular hexagon will intersect on a coordinate plane then it will create two intersection points.

Thus, the intersection of a circle and a regular hexagon can be two pints option (C) two points is correct.

Answer:

maria : 1/3 =0.3 line on top of three

franco:1/4=0.25

Step-by-step explanation:

tried my best hope its right :)

Answer:

Maria: 1/3 cups for each gallon

Step-by-step explanation:

Maria: 2/3 for every 2 gallons.  2/3:2

Franco: 1 1/4 for every 5 gallons.  1 1/4/:5

Okay, so I'm actually going to do it my way.

Maria : [tex]\frac{2}{3} = 4/6\\\frac{4}{6} /2 =2/6[/tex]

So, I simply turn it into a bigger fraction and cut it in half!

So, Maria uses 1/3 of a cup for each gallon

Hope this will help you figure out Franco's!!!
