If t represent the number of tickets purchased for a baseball game, which scenario is modeled by the equation, 32.50t + 5 = 28.7

5t + 20, to determine the number of tickets that result in the same cost for both levels? The price for the lower level is $5.00 a ticket, plus $32.50 for a discounted parking pass. The middle-level tickets are $20 each, plus $28.75 for a parking pass. The price for the lower level is $32.50 a ticket, plus $5.00 for a discounted parking pass. The middle-level tickets are $28.75 each, plus $20.00 for a parking pass. The price for the lower level is $32.50 a ticket, plus $20.00 for a discounted parking pass. The middle-level tickets are $28.75 each, plus $5.00 for a parking pass. The price for the lower level is $28.75 a ticket, plus $5.00 for a discounted parking pass. The middle-level tickets are $32.50 each, plus $20.00 for a parking pass.

Considering the expression x/2 + y2. Which statements are true?Mark all that apply.
Svet_ta [14]

Answer:

  D.  8/2 +(-10)² = 104

Step-by-step explanation:

To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.

The respective expression values are ...

  A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83

  B 31 ≠ 61

  C 52 ≠ 61

  D 104 =104 . . . . true statement

__

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.

Topic: The Quadratic Formula
Finger [1]

Answer:

Step-by-step explanation:

The quadratic formula for a equation of form

ax²+bx + c = 0 is

x= \frac{-b +- \sqrt{b^2-4ac} }{2a}

For the first equation,

x²+3x-4=0,

we can match that up with the form

ax²+bx + c = 0

to get that

ax² =  x²

divide both sides by x²

a=1

3x = bx

divide both sides by x

3 = b

-4 = c

. We can match this up because no constant multiplied by x could equal x² and no constant multiplied by another constant could equal x, so corresponding terms must match up.

Plugging our values into the equation, we get

x= \frac{-3 +- \sqrt{3^2-4(1)(-4)} }{2(1)} \\= \frac{-3+-\sqrt{25} }{2} \\ = \frac{-3+-5}{2} \\= -8/2 or 2/2\\=  -4 or 1

as our possible solutions

Plugging our values back into the equation, x²+3x-4=0, we see that both f(-4) and f(1) are equal to 0. Therefore, this has 2 real solutions.

Next, we have

x²+3x+4=0

Matching coefficients up, we can see that a = 1, b=3, and c=4. The quadratic equation is thus

x= \frac{-3 +- \sqrt{3^2-4(1)(4)} }{2(1)}\\= \frac{-3 +- \sqrt{9-16} }{2}\\= \frac{-3 +- \sqrt{-7} }{2}\\

Because √-7 is not a real number, this has no real solutions. However,

(-3 + √-7)/2 and (-3 - √-7)/2 are both possible complex solutions, so this has two complex solutions

Finally, for

4x² + 1= 4x,

we can start by subtracting 4x from both sides to maintain the desired form, resulting in

4x²-4x+1=0

Then, a=4, b=-4, and c=1, making our equation

x=\frac{-(-4) +- \sqrt{(-4)^2-4(4)(1)} }{2(4)} \\= \frac{4+-\sqrt{16-16} }{8} \\= \frac{4+-0}{8} \\= 1/2

Plugging 1/2 into 4x²+1=4x, this works as the only solution. This equation has one real solution

Answer:

(1436.8cm³)  let me know if that helps

Step-by-step explanation:

-so if the diameter is a straight line and it's 15 cm

-The formula for the sphere it would be v=4/3πr³

-The radius is going to be r=7cm

-v = 4/3 π (7cm)³

-so you would type in 4/3 x 3.14 x 7 ³ =1,436

  - 3.14 or π

- you would round it to the nearest 10th (1436.8cm³)
