Since the percentage is 8/10, we can take it and mutiply it by 10 (8 and 10) to get 80/100. The percentage is 80%.
I’m guessing this is a trick question, but I’m gonna go with what I think
Answer: She would have to pay 58 in a month if she downloaded 50 songs with the subscription from the streaming music services. She’d pay 50 dollars for 50 songs, since one song costs a dollar.
Answer:
8 and 3
Step-by-step explanation:
We first want to add 5 to both sides, making the equation x^2 -11x +24=0, now, we want to use the quadratic formula, which is( -b <u>+</u> sqrt(b^2 -4ac)) /2a
for equations of the form ax^2 + bx +c, so in our case, a =1, b= -11, and c=24,
when you plug in the variables, you will get the answers! :)
<h3>Answer:</h3>
3. R(x) = 25,500 -720x -12x²
<h3>Explanation:</h3>
Starting from 340 tickets, the number of tickets increases by 4 for each unit change in x. Hence, tickets sold will be (340 +4x).
Starting from $75, price per ticket decreases by $3 for each unit change in x. Hence ticket price is (75 -3x).
Revenue from ticket sales is the product of the number of tickets and the price at which they are sold:
... R(x) = (340 +4x)·(75 -3x)
... R(x) = 25,500 -720x -12x² . . . . . matches the 3rd choice
