Your jazz band is selling tickets for a school dance. Student tickets are $8.00 and adult tickets are $15.00. If you sold 167 tickets for a total revenue of $1630, how many of each ticket did you hand sell?
Write and solve a system of equations for each scenario.
Answer:
Step-by-step explanation:
8s + 15a = 1630
s + a = 167
8s + 15a = 1630
-8s - 8a = -1336
7a = 294
a = 42 adult tickets
s + 42 = 167
s = 125 student tickets
My mom packed my lunch three of the past five days, so the probability of my mom packing my lunch is 3/5. Is this Experimental or Theoretical?
Answer:
definitely theoretical. Seems how mom packed the lunch 3/5 times a week, the pattern will follow
Step-by-step explanation:
The given probability is the theoretical probability.
Given that, my mom packed my lunch three of the past five days, so the probability of my mom packing my lunch is 3/5.
What are theoretical and experimental probabilities?Experimental probability is based on the results of several trials or experiments. Theoretical probability is calculated by taking the number of favourable outcomes over the total number of outcomes. Experimental probability is calculated by taking the actual outcomes over the total number of trials.
Now, my mom packed my lunch for three days of the past five days.
Number of favourable outcomes=3
Total number of outcomes=5
Probability of an event =3/5
Therefore, the given probability is the theoretical probability.

How do you know whether an equation is an identity? How many solutions does an identity have? Explain.
Choose the correct answer below.
A.
An equation is an identity if it can be rewritten as an equation of the form "variable=number," such as x=5 or y=3. Such an equation has an infinite number of solutions because a variable can be any number.
B.
An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.
C.
An equation is an identity if it can be rewritten as an equation of the form "variable=number," such as x=5 or y=3. Such an equation has only one solution, and the solution is called the identity of the variable.
Answer:
the correct answer is B
Step-by-step explanation:
HAVE A GREAT DAY!
The correct answer is B.
An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.
An equation is a mathematical statement which is true only for some set of values.
An identify is a mathematical statement which is true only for all the values.
Here, only option B "An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable." satisfies the condition.
So, option B is correct.

Answer:
b) all interior angles are right angles
Given : angle1 cong angle2 Prove p||q
Answer:
Step-by-step explanation:
The two angles ∠1 and ∠3 are equal by the alternate exterior property.
What are lines and angles?Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines.
A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints.
According to the alternate outside angle theorem, alternate exterior angles are regarded as congruent angles or angles of equal measure when two parallel lines are intersected by a transversal.
Here the two angles ∠1 and ∠3 are alternate exterior angles and are equal to each other.

An average drop of blood contains about 1.6 x 10^4 white blood cells. A rare drop of blood contains about 5 x 10^4 white blood cells. What is the difference between the number of white blood cells in a rare drop of blood and the number of white blood cells in an average drop of blood?
Answer:
3.4 x 10^4
Step-by-step explanation:
1.6 x 10^4 - 5 x 10^4 = -3.4 x 10^4
5 x 10^4 - 1.6 x 10^4 = 3.4 x 10^4
The measures of two angles of a triangle are each four times the measure of the third angle. What is the measure of the third angle? (hint: The sum of the angle measure of a triangle are 180°)
Answer:
20°
Step-by-step explanation:
The sum of all triangles must equal 180 degrees.
The measure of two angles of a triangle are each four times the measure of the third angle.
2x+x/4=180
The equation above illustrates a way to solve for X which represents the the independent angle measurement from the two angles.
x = 80
Above, we solved for x by simplifying both sides of the equation and then isolating x. So hmm...does 80 make sense?
80 / 4 = 20. So it is four times the measure of the 3rd angle. But does it all equal to 180?
2 * 80 + 20 = 180.
The angle of the third angle is 20 degrees.
The total number of triangles must be 180 degrees, and the two angles of a triangle are measured every four times the third angle measurement. So, the calculation can be defined as follows:
[tex]\to \bold{2x+ \frac{x}{4}=180}[/tex]
The above equation illustrates a way of resolving the indie angle measurement from both angles for X.
[tex]\bold{x = 80}[/tex]
Above we solved x through simplification and isolation of the x on both sides of the equation.
So 80 is meaningful.
[tex]\frac{80}{4 }= 20.[/tex] Thus, 4 times the 3rd angle measurement. But it all equates to 180.
[tex]\to \bold{ 2+4 = 2 \times 80 + 20.}[/tex]
Therefore, the third angle is 20 degrees.
