A 3-pack of movie tickets costs $20.55. What is the unit price?

1 answer:

6 0

Unit price is the cost of a single ticket.

To find the unit price, divide the total cost by the number of tickets:

20.55 / 3 = $6.85 each.

Simplify<br> 50(x^2+7x+6)

worty [1.4K]

Distribute $50$ to every term inside the parentheses.

$50\cdotx^2+50\cdot7x+50\cdot6$

Simplify with multiplication.

$\huge\boxed{50^2+350x+300}$

You can't simplify further by adding, so leave the answer as-is.

7 pipes fill a tank in 50 minutes. How many minutes does it take if there are 11 pipes?

Alekssandra [29.7K]

Answer: With 11 pipes, you need 31.82 minutes to fill the tank.

Step-by-step explanation:

Let's define R as the rate at which one single pipe can fill a tank.

We know that 7 of them can fill a tank in 50 minutes, then we have the equation:

7*R*50min = 1 tank

Whit this equation, we can find the value of R:

R = 1 tank/(7*50min) = (1/350) tank/min.

Now that we know the value of R, we can do the same calculation but now with 11 pipes.

Then the time needed to fill the tank, T, is such that:

11*(1/350 tank/min)*T = 1 tank

We need to isolate T.

T = 1 tank/(11*(1/350 tank/min)) = 31.82 min

With 11 pipes, you need 31.82 minutes to fill the tank.

What are the coordinates of the point on the directed line segment from (–9, -7) to

pentagon [3]

Answer:

Step-by-step explanation:

Saving the long, drawn out derivation of the formulas to find the x and y coordinates of the directed point, suffice it to say that it is:

x coordinate: $\frac{bx_1+ax_2}{a+b}$ and

y coordinate: $\frac{by_1+ay_2}{a+b}$

where x1, x2, y1, and y2 are the coordinates from the given points and a and b are the numbers in the ratio, namely a = 3 and b = 4. Filling in accordingly:

the x coordinate of the directed point is

$\frac{4(-9)+3(-2)}{7}$ which simplifies down to -6, and

the y coordinate of the directed point is

$\frac{4(-7)+3(7)}{7}$ which simplifies down to -1.

The coordinate of the point is (-6, -1). Write that down so you don't forget it.
