Answer:

A. 1.20x; individuals signing up the day of the activity get charged 20% more

Step-by-step explanation:

Amount charged before the day of activity = x

Amount charged on any individual who decides to sign up on the day of activity would be the normal price, x dollars, plus an additional price of 0.20x dollars.

0.20x = 20% of x.

That is, the additional fee added to the normal price is 20% of the normal price.

Therefore, amount paid on the day of the activity is x + 0.20x = 1.20x dollars.

What this fee means is that those who decide to sign up on the day of the activity are charged 20% more.

Answer:

y= - 4/6x+1.66

Step-by-step explanation:

To get the slope you subtract y2-y1 / x2-x1. This gives the slope. Then you need to get the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Answer:

28 more beef cattle.

Step-by-step explanation:

Do 16*4 since 1/4 = 16 beef cattle. 16*4=64 total beef cattle on the farm.

Then do if there are 24 dairy cattle in the barn and that is 2/3 of all the cows.

1/3 = 12 so the total number of dairy cows on the farm is 12*3=36

Now subtract 64-36=28

There are 28 more beef cattle than dairy cows.

Hope this Helps!!

The number of cattle more than the number of beef will be 12.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Two-thirds of the dairy cattle on a farm are in the barn. One-fourth of the beef cattle are in the barn. There are 24 dairy cattle and 16 beef cattle in the barn.

Then the number of cattle is calculated as,

⇒ (2/3) x 24

⇒ 16

Then the number of beef is calculated as,

⇒ (1/4) x 16

⇒ 4

Then the number of cattle more than beef is calculated as,

⇒ 16 - 4

⇒ 12

The number of cattle more than the number of beef will be 12.

The lowest form of the ratio 84 : 99 is 28 : 33.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A ratio 84 : 99.

The lowest form of the ratio is when it can not be simplified further.

Answer:

80 degrees

Step-by-step explanation:

both intersections are the same, so we can count them as one. We notice that one line is a straight line compared to other so we can subtract 100 from 180 and get 80

Answer:

80

Step-by-step explanation:

Vertical angles equal 360 in total and the angles across from each other equal the same. 100 x 2 = 200

360-200 = 160

Answer:

Some points are: (1, 4), (0, 9), and (3, -6), just to name a few.

Step-by-step explanation:

We can find out an ordered pair for this equation by plotting the line 5x + y = 9 on a graph. If you graph 5x + y = 9, then we see that the point (1, 4) is a point that the line intersects. Let's substitute that values:

5(1) + 4 = 9

Order of operations, multiply first...

5(1) = 5

Then it becomes...

5 + 4 = 9

We can see that 5 plus 4 actually does equal 9, so the point (1, 4) works. Let's try a different point. We can see the point (0, 9) is another point that the line intersects. Same process for this point too.

5(0) + 9 = 9

Then...

5(0) = 0

0 + 9 = 9

We see that 0 plus 9 ALSO works, but let's try one more time. Another point that works is the point (3, -6) Again, same process.

5(3) + -6 = 9

That is equal to:

5(3) - 6 = 9

Simplify...

5(3) = 15

15 - 6 = 9

15 minus 6 works as well! Any point that the line intersects will be a solution for the equation. I hope this helps!

Answer: 2 inches

Step-by-step explanation:

14 inches

Step-by-step explanation:

Length of the hole = 16(½) inches

Length of the dirt = 8(¾)inches

The distance between the top of the pile to the bottom of the hole = ?

Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.

Distance from the top to the bottom = length of dirt + length of the hole

Length of dirt = 8×¾ = 6 inches

Length of the hole = 16 × ½ = 8 inches

Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches

Distance from the top of the dirt to the bottom of the hole = 14 inches

Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left

Distance left = length of hole - length of dirt

Distance left = 8 - 6 = 2 inches .

Answer:

A & B

Step-by-step explanation:

See attachment for complete question

Given

[tex]y = \frac{1}{2}x[/tex]

Analyzing the given options

Option A:

[tex]6y = 3x[/tex]

Divide both sides by 6

[tex]\frac{6y}{6} = \frac{3x}{6}[/tex]

[tex]y = \frac{3x}{6}[/tex]

[tex]y = \frac{1}{2}x[/tex]

This is true for the given expression:

Option B:

From the graph:

x = 2, when y = 1

x = 4, when y = 2

Solving for the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2 -1}{4 - 2}[/tex]

[tex]m = \frac{1}{2}[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 1 = \frac{1}{2}(x - 2)[/tex]

[tex]y - 1 = \frac{1}{2}x - 1[/tex]

Add 1 to both sides

[tex]y - 1 +1 = \frac{1}{2}x - 1 + 1[/tex]

[tex]y = \frac{1}{2}x[/tex]

This is also true for the given expression.

Option C:

From the graph:

x = 2, when y = 4

x = 4, when y = 8

Solving for the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{8 - 4}{4 - 2}[/tex]

[tex]m = \frac{4}{2}[/tex]

[tex]m =2[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 4 = 2(x - 2)[/tex]

[tex]y - 4 = 2x - 4[/tex]

Add 4 to both sides

[tex]y - 4 + 4= 2x - 4 + 4[/tex]

[tex]y = 2x[/tex]

This isn't true for the given expression.

Option (D):

From the table:

x = 2, when y = 1

x = 4 when y = 3

Solving for the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{3 - 1}{4 - 2}[/tex]

[tex]m = \frac{2}{2}[/tex]

[tex]m = 1[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 1 = 1 * (x - 2)[/tex]

[tex]y - 1 = x - 2[/tex]

[tex]y = x - 2 +1[/tex]

[tex]y = x - 1[/tex]

This isn't true for the given expression.
