Answer:
A. The number of dinner tickets sold.
Step-by-step explanation:
Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold; however, she remembered that she was given 100 tickets and she collected $900.
Let us represent
Number of dinner tickets = x
Number of dessert tickets = y
From the above question, our system of equations is given as:
x + y = 100...... Equation 1
$10 × x + $6 × y = $900
10x + 6y = 900...... Equation 2
Therefore, the variable x in this system of equations represents the number of dinner tickets sold.
Option A is the correct option.
Write the equation of the line passing through the point (-2; 2) that is
PERPENDICULAR to y = -2x + 1 in slope-intercept form. 
Answer:
2y-x-6=0
Step-by-step explanation:
Peter has built a gazebo, whose shape is a regular heptagon, with a side length of $1$ unit. He has also built a pathway around the gazebo, of constant width $1$ unit, as shown below. (Every point on the ground that is within $1$ unit of the gazebo and outside the gazebo is covered by the pathway.) Find the area of the pathway.
Answer:
Area of pathway = 10.375 unit²
Step-by-step explanation:
Given - Peter has built a gazebo, whose shape is a regular heptagon, with
a side length of 1 unit. He has also built a pathway around the
gazebo, of constant width 1 unit, as shown below.
To find - Find the area of the pathway.
Proof -
Central angle = [tex]\frac{360}{7}[/tex] = 51.43°
Now,
Central angle / 2 = [tex]\frac{360}{14}[/tex] = 25.71°
And
height = [tex]\frac{1}{2}.\frac{1}{tan25.41}[/tex] = 1.038
Now,
Inner area of gazebo = 7·[tex]\frac{1}{2}[/tex]·1·(1.038) = 3.634 unit²
Outer area of gazebo = ([tex]\frac{2.038}{1.038}[/tex])²·(3.364) = 14.009 unit²
∴ we get
Area of pathway = Outer area - Inner area
= 14.009 - 3.634
= 10.375 unit²
⇒Area of pathway = 10.375 unit²

Step-by-step explanation:
Total cost: 587.50
He has: 150.00 + 200.00 = 350.00
He needs an additional: 587.50 - 350.00 = 237.50
He saves 12.50 per day.
137.50/12.50 = 19
Answer: 19 days
Answer:
19 days
Step-by-step explanation:
150+200=350
587.5-350=237.5
237.5/12.5=19
A tile is selected from seven tiles, each labeled with a different letter from the first seven letters of the alphabet.
The letter selected will be recorded as the outcome.
Consider the following events.
Event X: The letter selected comes before "E".
Event Y: The letter selected is found in the word "FACE".
Give the outcomes for each of the following events.
If there is more than one element in the set, separate them with commas.
Answer:
Step-by-step explanation:
U= {A,B,C,D,E,F,G}
X = {A, B, C, D}
Y = {A, C, E, F}
a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}
B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}
c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}
Element in the given sets will be [tex]\left \{ A,B,C,D \right \}[/tex] and [tex]\left \{ A,C,E,F \right \}[/tex]
Given information,
A tile is selected from seven tiles, each labeled with a different letter from the first seven letters of the alphabet.
X: The letter selected comes before "E".
Y: The letter selected is found in the word "FACE".
The outcomes in favour of X will be:
[tex]X=[/tex] [tex]\left \{ A,B,C,D \right \}[/tex]
The outcomes in favour of Y will be:
[tex]Y=\left \{ A,C,E,F \right \}[/tex]
Therefore,
Element in the given sets will be [tex]\left \{ A,B,C,D \right \}[/tex] and [tex]\left \{ A,C,E,F \right \}[/tex]

Answer:
3:2
Step-by-step explanation:
Triangles ABC and PMN are similar. This is evident from the marks identifying equal angles.
The ratio of the two longest sides is 20:30, or 2:3.
The ratio of the two shortest sides is 12:18, or 2:3.
Finally, the ratio of the two sides of intermediate length is 16:24, or 2:3.
The scale factor of the alrger triangle to the smaller triangle is 3:2.
If you roll a standard die, what is P(6) ? (probability of rolling a 6)
Answer:
1/6
Step-by-step explanation:
There are 6 sides to a die, and 6 occupies one side, so the probability of rolling a 6 is 1/6.
Answer:
1/6 or 16.7%
Step-by-step explanation:
When you roll a standard die, the probability of getting 6 is 1/6 or 16.7%

1. 72, 32, 74, 66, 71, 45, 38, 49, 66, 69, 75, 34, 102
put the numbers in order

Q1 = (38 + 45)/2 = 41.5
Q2 (the median) = 66
Q3 = (72 + 74)/2 = 73
Interquartile range (IQR) = Q3 - Q1 = 73 - 41.5 = 31.5

solve 7/t+8=6v-8u for t
Answer:
t=7/(6v-8u-8)
Step-by-step explanation:
Isolate t
7/t=6v-8u-8
7/6v-8u-8=6v-8u-8*t/6v-8u-8
t=7/(6v-8u-8)
You can simplify it
t=7/2(3v-4u-4)

Finding angles!!
Answer:
Angle 1: 115
Angle 2: 65
Angle 3: 115
Angle 4: 65
Angle 5: 115
Angle 6: 65
Angle 7: 115
Step-by-step explanation:
Find the value of angle 2 by applying the vertical angles theorem (65)
Find the value of angle 1 by applying the supplementary angles theorem from the original angle (180 - 65 = 115)
Find the value of angle 3 by applying the vertical angles theorem from angle 1 (115)
Angles 4, 5, 6, and 7 are on a line parallel to the orginal line, cut by the same transversal, so they have the same values, according to the same side interior/exterior angles theorems.
