There are 200 end of the year school dance tickets available. Students who have perfect attendance are able to purchase them in
ivanzaharov [21]

Answer:

9% of tickets were sold in advance for the dance

Step-by-step explanation:

In order to find the percent of the tickets purchased in advance, you have to divide the number of tickets already purchased by the total number of tickets.

18 / 200 = 0.09

Now, you will multiply this number by 100 to get the percentage.

0.09 * 100 = 9

9% of the tickets that were purchased in advance are able to purchase.

URGENT HELP PLEASE
sammy [17]

Answer:

slope1 : 7,  slope 2 = 3     solution: (2,5)

Step-by-step explanation:

I simplify some steps

pair 1:    x1   0     2

            y1   -9     5 ........ -9, y1 intercept

pair 2:   x2   0    2

             y2  -1    5   ........ -1, y2 interept

2 pairs meet at (2,5)

y=7x-9 ......A

y=3x-1  ......B

A-B    0=4x-8

4x=8

x=2

y=5

slope 1=( y2-y1) / (x2-x1) = (5- -9)/(2-0) = 14/2 =7

slope 2 = (5 - -1) / (2 - 0) = 6/2 = 3

Choose the equation that is the standard form of
Ronch [10]
For this case we have the following equations:
 5y = 3-2x
 5y-3 = -2x
 2x + 5y = 3
 2x + 5y-3 = 0
 The standard form of the equations is given by:
 Ax + By = C
 Therefore, the equation written in its standard form is:
 2x + 5y = 3
 Where,
 A = 2
 B = 5
 C = 3
 Answer:
 
The equation that is the standard form is:
 
2x + 5y = 3

Easton wants to put a variety of donuts in a display case. The case is large enough to hold 100 donuts. Complete the table below
shutvik [7]

The amounts for each donut are given as follows:

  • Strawberry: 15.
  • Chocolate: 45.
  • Sprinkle: 40.

<h3>How to obtain the amounts?</h3>

The amounts for each donut are found applying the proportion, multiplying the decimal equivalent of each percentage by the total number of donuts.

From the problem, the total number of donuts is given as follows:

100 donuts.

The percentages of each type of donuts are given as follows:

  • Strawberry: 15%.
  • Chocolate: 45%.
  • Sprinkle: 40%.

The decimal equivalent of each percentage is given as follows:

  • Strawberry: 0.15.
  • Chocolate: 0.45.
  • Sprinkle: 0.4.

Hence the amounts are given as follows:

  • Strawberry: 15, as 0.15 x 100 = 15.
  • Chocolate: 45, as 0.45 x 100 = 45.
  • Sprinkle: 40, as 0.4 x 100 = 40.
