Answer:
The area of the base of the pencil holder in square centimeters is 18 square centimeters
Step-by-step explanation:
The volume of a triangular prism is given as base area X height.
To get the base area, we can quickly shuffle the order of the terms to make sure that the base area is the subject of the formula.
Base area = volume of prism / height
Base area = 216/12 = 18 square centimeters
Therefore, the area of the base of the pencil holder in square centimeters is = 18 square centimeters
The school that Anthony goes to is selling tickets for a choir concert. On the first day of ticket sales his school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. What is the price of a senior citizen ticket?
Answer:
A senior citizen costs $8
Step-by-step explanation:
Represent senior citizens with S and children with C.
The first day is represented as:
[tex]3S + C = 38[/tex]
The second day is represented as:
[tex]3S + 2C = 52[/tex]
Required
Solve for C and S
Make C the subject in the first equation
[tex]C = 38 - 3S[/tex]
Substitute 38 - 3S for C in the second equation
[tex]3S + 2(38 - 3S) = 52[/tex]
[tex]3S + 76 - 6S = 52[/tex]
Collect Like Terms
[tex]3S - 6S = 52 - 76[/tex]
[tex]- 3S = -24[/tex]
Divide through by -3
[tex]S = 8[/tex]
Recall that: [tex]C = 38 - 3S[/tex]
[tex]C = 38 - 3 * 8[/tex]
[tex]C = 38 - 24[/tex]
[tex]C = 14[/tex]
Hence, a senior citizen costs $8

Solve (x + 3)(x - x = 0. (2 points) x = 3, x = -8 O x = -3, x = 8 x = 3, x = 8 O x = -3, X = -8
answer:
the answer is -3 and 8
Step-by-step explanation:
we will place -3 in the equation
(x+3)(x-x)=0
(-3+3)=0 (because -3+3 will cut down together)
we will place two 8(eights) in the equation
(8-8)=0
final answer is
(0)(0)=0
so -3 and 8 fits well in the equation

Number 21 plsss helppppp
Answer:
B
Step-by-step explanation:
First off, we see that x ≥ -2. That little horizontal line right under the > sign indicates that x is "greater than or equal to" -2. Because we want to include -2 in the solution set, the dot on the number line at -2 should be shaded in.
This already eliminates A and D.
Now, we're left to choose between B and C.
Well, we know that x is greater than or equal to -2, so possible values of x should be numbers that are more positive than -2, or that point in the positive direction. That's exactly what B illustrates, so that's our answer.

Memorial Stadium has worked with the same advertising company for 10 years. According to the company's data the stadium has spent approximately $2.5 million on advertising over that period for 100 events. If the patrons to all of these events numbered 18.5 million, what is the ratio of patrons to advertising dollars?
Answer:
7.4:1
Step-by-step explanation:
The rate of patrons to advertising dollar is7.4 patrons per dollar.
What is rate?A rate is a comparison between two quantities that's calculated by dividing one quantum by the other. The quotient a/ b is appertained to as the rate between a and b if a and b are two values of the same kind and with the same units, similar that b isn't equal to 0. rates are represented by the colon symbol(). As a result, the rate a/ b has no units and is represented by the memorandum ab.
Given:
The colosseum has spent roughly $2.5 million on advertising over that period for 100 events.
So, the rate of patrons to advertising
= 18.5 million patrons to $2.5 million
= 18.5/2.5
= 7.4 patrons per dollar

Thirteen candy bars weigh 26 ounces what is the weight of 35 candy bars
Answer:
70 ounces
Step-by-step explanation:
We can solve the weight of 35 candy bars by first finding the weight of one and multiplying by 35.
If 13 candy bars each weigh 26 ounces, one will weigh 2. We can write this out as shown:
13x = 26
x = 2
Now we simply multiply by 35 to get the total weight of 35 candy bars:
35x = 35(2) = 70

The are of the square is 3*3 = 9
Since we have two squares we need to mulitply by 2
9*2 = 18 is the total area of the squares
if you draw a line from the one square to the other you make a rectangle in the middle
the are of the rectangle is 10*3 which is 30
Two triangle has appared as we draw the line from one square to the other square.
The height of the traingle is (7 - 3)/2 which is 2
(2*10) / 2 = which is 10
Since we have 2 triangle we get result as 2*10 = 20
20+30+18 = 68

Step-by-step explanation:
after a 30% reduction, you purchase a dictionary for $30.80 what was the dictionary price before the reduction
Answer:
Well the original price would be $44
Step-by-step explanation:
So make an equation
Lets make X stand for the price before the deduction
so x-x(0.3)=30.80
Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change
Now just solve the equation
You’ll get 44.

Mr. Patel bought his 3 friends Casio G-Shock watches for Christmas. The retail price for each watch on Amazon was $39.91. How much did he pay for all 3 watches, excluding tax?
Answer:
Mr. Patio paid $312.00 for the three watches
Step-by-step explanation:
The price of one of the Casio G-Shock watches that Mr. Patel bought his 3 friends for Christmas is $39.91.
For Mr. Patio to have bought this watch for each of his 3 friends, we have that the cost will be multiplied by three. He is spending three times the amount he would have spent if he is buying for only a single person.
Cost = 39.91 X 3 =$312.00
Mr. Patio paid $312.00 for the three watches

Which equation represents a line which is parallel to the line y=5/6x−7?
Answer: The choice will be any equation where the slope is the same and the y-intercept is different.
[tex]y=\frac{5}{6}x + b[/tex]
Step-by-step explanation: Using slope-intercept form, y = mx + b,
m is the slope, b is the y-intercept.
Parallel lines will have the same slope.
So, you are looking for another equation that has 5/6 as the coefficient of x.
It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.
