In a trivia contest, players form teams and work together to earn as many points as possible for their team. Each team can have between 3 and 5 players. Each player can score up to 10 points in each round of the game. Elena and four of her friends decided to form a team and play a round.
Write an expression, an equation, or an inequality for each quantity described here. If you use a variable, specify what it represents.
1. the number of points that Elena's team earns in one round
2. the number of points Elena's team earns if each player misses one point
3. the number of players in a game if there are at least 3 teams
Answer:
(i) From 0 to 50.
(ii) From 3 to 5.
(iii) From 3R to 5R, where R=3,4,5,...
Step-by-step explanation:
Let N be the number of players in a team.
As each team can have numbers of player ranging from 3 to 5, so
[tex]3\leqN\leq5\cdots(i)[/tex]
Let P be the points scored by one player in one round of the game.
As each player can score up to 10 points in each round of the game, so
[tex]0\leq P \leq 10\cdots(ii)[/tex]
(1) There are 5 members in the team formed by Elena.
So, points earned by 5 players in 1 round = 5P
From equation (ii), the range is
[tex]0\leq 5P \leq 50[/tex]
Hence, the points earned by Elena's team is ranging from 0 to 50.
(2) If each played misses 1 point, then,
Points earned by 1 player in 1 round = 10-1=9
Hence, points earned by 5 players in 1 round = 9x5=45.
(3) Let R (an integer) denoted the number of teams.
As there are at least 3 teams in the game, so
[tex]R\geq3\cdots(iii)[/tex]
As the number of players in one team is N, so
the number of players in R team is NR, where R=3,4,5,...
Now, from equation (i)
[tex]3R\leqNR\leq5R[/tex]
Hence, if there are at least 3 teams, then the number of players is ranging from 3R to 5R.
For R=3, the number of players in the game is ranging from 3x3=9 to 5x3=15.

12(x−13)=13(12−x) x=?
Answer:
x = 12.48
Step-by-step explanation:
Simplifying
12(x + -13) = 13(12 + -1x)
Reorder the terms:
12(-13 + x) = 13(12 + -1x)
(-13 * 12 + x * 12) = 13(12 + -1x)
(-156 + 12x) = 13(12 + -1x)
-156 + 12x = (12 * 13 + -1x * 13)
-156 + 12x = (156 + -13x)
Solving
-156 + 12x = 156 + -13x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '13x' to each side of the equation.
-156 + 12x + 13x = 156 + -13x + 13x
Combine like terms: 12x + 13x = 25x
-156 + 25x = 156 + -13x + 13x
Combine like terms: -13x + 13x = 0
-156 + 25x = 156 + 0
-156 + 25x = 156
Add '156' to each side of the equation.
-156 + 156 + 25x = 156 + 156
Combine like terms: -156 + 156 = 0
0 + 25x = 156 + 156
25x = 156 + 156
Combine like terms: 156 + 156 = 312
25x = 312
Divide each side by '25'.

Lina and Josh each made a factor tree to find the prime factorization of 126. Lina's Solution Josh's Solution 2 factor trees. Alina's factor tree of 126. 126 branches to 3 and 42. 42 branches to 6 and 7. 6 branches to 2 and 3. The equation is 126 = 2 times 3 squared times 7. Josh's factor tree of 126. 126 branches to 2 and 63. 63 branches to 9 and 7. The equation is 126 = 2 times 7 times 9. Which statement explains the accuracy of the students' work? Lina's solution is correct because it expresses 126 as a product of prime factors. Josh's solution is correct because the factor tree of every even number must begin with 2 and its factor pair. Both solutions are correct because they both express 126 as a product of factors. Neither solution is correct because the factor tree should have begun with 6 and 21.
Answer:
Lina's solution is correct because it expresses 126 as a product of prime factors.
Step-by-step explanation:
Prime factorization can be defined as a methodology of breaking down an original number down into the set of prime numbers which when multiplied together give us the original number.
Prime factorization makes use of a factor tree
The number we are to carry out prime factorization on is 126
126
/\
3 42
/\
6 7
/\

The Prime Factorization is:
2 x 3 x 3 x 7
Hence, Lina's factor tree of 126. 126 branches to 3 and 42. 42 branches to 6 and 7. 6 branches to 2 and 3. The equation is 126
= 2 times 3 squared times 7.
Is correct.

Answer:
∠ A = 60°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{15}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{13}{15}[/tex] ) ≈ 60°
------------------------------------------------
Using the cosine ratio in the right triangle
cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus
∠ R = [tex]cos^{-1}[/tex] ( [tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. places )

Step-by-step explanation:
The balance owed on your credit card triples from $700 to $2100 in 12 months. If the balance is growing linearly then it would take 45.4 months to reach $6000. If, on the other hand, the balance is growing exponentially, f(x)=700(1+0.096)x where x represents the number of months, what would the balance be after 45.4 months? Round your answer to the nearest cent.
Answer:
If the balance is growing exponentially the balance after 45.4 months will be $44,925.94.
Step-by-step explanation:
The exponential growth equation is:
[tex]f(x)=700(1+0.096)^{x}[/tex]
Compute the value of f (x) for x = 45.4 as follows:
[tex]f(x)=700(1+0.096)^{x}[/tex]
[tex]=700(1+0.096)^{45.4}\\\\=700\times (1.096)^{45.4}\\\\=700\times 64.1799181\\\\=44925.94267\\\\\approx 44925.94[/tex]
Thus, if the balance is growing exponentially the balance after 45.4 months will be $44,925.94.

Sam will take four science tests this quarter. Her scores on three of the tests
are shown below.
Test 1
83%
Test 2
91%
Test 3
88%
Test 4
?
What does Sam need to score on the fourth test to ensure that she will have an
average of 90% for all four tests?
%
Answer:
98%.
Step-by-step explanation:
The following data were obtained from the question:
Test 1 (T₁) = 83%
Test 2 (T₂) = 91%
Test 3 (T₃) = 88%
Test 4 (T₄) =?
AVERAGE = 90%
We can obtain the score of 4th test by doing the following:
AVERAGE = (T₁ + T₂ + T₃ + T₄) /4
90 = (83 + 91 + 88 + T₄) /4
90 = (262 + T₄) /4
Cross multiply
90 × 4 = 262 + T₄
360 = 262 + T₄
Collect like terms
360 – 262 = T₄
T₄ = 98%
Therefore, Sam need to score 98% in the 4th test in order to have an average score of 90%.

What is the value of x in the figure below? In this diagram, ΔABD ~ ΔCAD.
Answer:
D
Step-by-step explanation:
The triangles CDA and ADB are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{AD}[/tex] = [tex]\frac{DA}{DB}[/tex] , substitute values
[tex]\frac{13}{x}[/tex] = [tex]\frac{x}{3}[/tex] ( cross- multiply )
x² = 39 ( take square root of both sides )
x = [tex]\sqrt{39}[/tex] → D

Answer:
58
Step-by-step explanation:
Step-by-step explanation:
AD=DC
So angle A is equal to angle C
Let Angle A be x
And angle ABD is equal to 90 degree
So in triangle ADB
90+32+x=180 (angle sum property)
x=180-122
x=58
As angle A and angle C are equal
So angle C=58 degrees

A business breaks even when the production costs are equal to the revenue. The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item. Write an expression for the revenue generated by selling x items. How many items would you need to sell to break even? Write an equation and solve it.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item.
The net income formula:
y= (5 - 4)x - 120
(5-4)= contribution margin per unit sold (x)
120= fixed costs
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 120 / 1
Break-even point in units= 120 units
Prove:
y= 1*120 - 120
y= 0

52-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is two inches more than seven times the length of the first piece. Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.
Answer:
First piece = a = 5 inches
Second piece = b = 10 inches
Third piece = c = 37 inches
Step-by-step explanation:
Let us represent:
First piece = a
Second piece = b
Third piece = c
52-inch piece of steel is cut into three pieces.
a + b + c = 52 inches
The second piece is twice as long as the first piece
= b = 2a
The third piece is two inches more than seven times the length of the first piece.
= c = 2 + 7(a)
Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.
a + b + c = 52 inches
Substitute 2a for b
2 + 7a for c
a + 2a + 2 + 7a = 52
Collect like terms
10a = 52 - 2
10a = 50
a = 50/10
a = 5 inches.
b = 2a
b = (2 × 5)
b = 10 inches
c = 2 + 7a
= 2 + 7(5)
= 2 + 35
= 37 inches
