The blues band, Jonny and the Silver Toads, charges $25 per ticket at their performances. Their next venue charges them $900 for use of the venue. Based on the inequality below, how many tickets, , do they need to sell in order to profit at least $1,925?
Answer:
The band must sell at least 113 tickets to make a net profit of at least $ 1,925.
Step-by-step explanation:
While the band charges $ 25 for each entrance ticket to their performances, and the venue charges them $ 900 for the use of the place, the number of tickets that must be sold for the band to obtain a profit of at least $ 1,925 arises from the following calculation:
1,925 + 900 = Costs plus profit
2,825 / 25 = Number of tickets needed to cover costs and profit
113 = Number of tickets needed to cover costs and profit.
Therefore, the band must sell at least 113 tickets to make a net profit of at least $ 1,925.
Kaitlyn start a job that pays $8.50 per hour Caitlin's manager says that if her job reviews were favourable she can expect annual pay rate increases of $0.75 which equation represents the relationship between years on the job and pay for our
Given:
Initial pay rate = $8.50 per hour
Increase in pay rate = $0.75 per year
To find:
The equation that represents the relationship between years on the job and pay for hour.
Solution:
Let x be the number of years and y be the pay rate after x years.
According to the question,
Increase in pay rate in 1 year = $0.75
Increase in pay rate in x year = $0.75x
So, variable pay rate = $0.75x
Initial pay rate = $8.50
So, the total pay rate is
Total pay rate = Initial pay rate + Variable pay rate
[tex]y=8.50+0.75x[/tex]
Therefore, the required equation is [tex]y=8.50+0.75x[/tex].

What is a quadratic equation?A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.
For the given situation,
The equation is 9x^2 + 3x – 4 = 0
The roots of the equation can be found by the formula,
[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]x=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]
here, a = 9, b = 3 and c = -4
Substitute the above values,
⇒ [tex]x=\frac{-3+\sqrt{3^{2}-4(9)(-4) } }{2(9)}[/tex] or [tex]x=\frac{-3-\sqrt{3^{2}-4(9)(-4) } }{2(9)}[/tex]
⇒ [tex]x=\frac{-3+\sqrt{9+144 } }{18}[/tex] or [tex]x=\frac{-3-\sqrt{9+144 } }{18}[/tex]
⇒ [tex]x=\frac{-3+\sqrt{153 } }{18}[/tex] or [tex]x=\frac{-3-\sqrt{153 } }{18}[/tex]
⇒ [tex]x=\frac{-3+12.36 }{18}[/tex] or [tex]x=\frac{-3-12.36 }{18}[/tex]
⇒ [tex]x=\frac{9.37}{18}[/tex] or [tex]x=\frac{-15.37}{18}[/tex]
⇒ [tex]x=0.5205[/tex] or [tex]x=-0.8538[/tex]
Hence we can conclude that the roots of the equation are x = 0.5205 and x = -0.8538. These roots are real, rational and unequal, thus option (B) is the correct answer.

Y= -2x+4 by graphing
Answer:
See attached file.
Step-by-step explanation:
This can be graphed by plugging in two distinct x values and solving each for y. That will give you two x,y coordinates to draw on the graph, which will let you trace the line defined by them.
You can get the points where the line intersects the axis by solving either variable for zero. Try giving x a value of 2 or 0 to find those.

Use the provided ruler to find the scale and the scale factor of the drawing. The scale measures 4 centimeters equal to 120 meters. The scale factor is ?
Answer:
1 : 3000
Step-by-step explanation:
Given that:
Scale measurement as following:
4 centimeters are equal to 120 meters.
To find:
The scale factor = ?
Solution:
First of all, let us learn about the definition of scale factor.
Scale factor means 1 unit on scale is equal to what length of actual measurement.
We are given that 4 cm on scale is equal to 120 meters of actual length.
We need to find nothing but how much 1 cm of scale is equal to actual length.
4 cm of scale = 120 meters or 12000 cm of actual length
Dividing by 4 on both sides, we get:
[tex]\frac{4}{4}[/tex] = 1 cm of scale = [tex]\frac{12000}{4}[/tex] = 3000 cm of actual length
Therefore, the scale factor is 1 : 3000
The scale factor is 1; 3000.
Given
The scale measures 4 centimeters equal to 120 meters.
What is the scale factor?The scale factor is a measure for the identical shapes, which look identical but have various scales or measures.
Scale factor means 1 unit on the scale is equal to what length of actual measurement.
4 cm of scale = 120 meters or 12000 cm of actual length.
1 cm of scale = 4/4
Then,
[tex]= \dfrac{12000}{4}\\\\=3000[/tex]
Hence, the scale factor is 1; 3000.

The correct option is D. No, the graph fails the vertical line test.
What is vertical line test?The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function. It is done by visually examining the number of intersections of the curve with vertical lines.
In the given graph, the graph of a function intersects the y axis twice.
Any vertical line in the x y plane must intersect the graph of a function at most once.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y = 4x be equation (1)
On simplifying the equation , we get
when x = 1
y = 4 ( 1 )
y = 4
when x = 2
y = 4 ( 2 )
y = 8

13 = √x^2+(x+7)^2 now you can solve
Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + (x + 7)² = 13² ← expand and simplify left side
x² + x² + 14x + 49 = 169 ( subtract 169 from both sides )
2x² + 14x - 120 = 0 ( divide through by 2 )
x² + 7x - 60 = 0 ← in standard form
(x + 12)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 12 = 0 ⇒ x = - 12
x - 5 = 0 ⇒ x = 5
But x > 0 , thus x = 5

Emma's grandmother sent her an $80 bookstore gift card for her birthday. Emma wants to make sure that her purchases don't exceed the amount of her gift card. So far, she has selected books that cost $8.95, $11.95, $22.25, and $24.95. She has also found a calendar she likes for $8.25. Round each item up to the next dollar to overestimate the total cost of the items in Emma's shopping basket.
Answer: total cost of the estimated items = $76
Step-by-step explanation:
Step 1
Rounding up each item to the next dollar
Book 1 = $8.95 ≈ $9.00
Book 2 = $11.95≈ $12.00
Book 3 = $22.25≈$22.00
Book 4 = $24.95≈$25.00
Calendar = $8.25 ≈$8.00
Step 2
The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00
=$76 which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.
Answer: 78$
Actual Estimate
$8.95 --------------------------$9.00
$11.95--------------------------$12.00
22.25--------------------------$23.00
$24.95------------------------$25.00
$8.25--------------------------$9.00
Then add the estimate numbers to get $78

Solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] and find value of k
Solving:
[tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex]
Convert mixed fraction into improper fraction
[tex]\frac{2}{5}K-\frac{7}{2}K =15[/tex]
Taking LCM of 5 and 2 we get 10
[tex]\frac{2*2K-7*5K}{10} =15\\\frac{4K-35K}{10} =15\\\frac{-31K}{10} =15[/tex]
Divide both sides by -31/10
[tex]\frac{-31K}{10}*\frac{-10}{31}=15* \frac{-10}{31}\\K=\frac{-150}{31} \\K=-4\frac{26}{31}[/tex]
So, solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]
