Answer:

You basically multiply the number outside the parentheses by everything inside.

So 2 × 6x = 12x,

2 × 5 = 10,

2 × 2y = 4y.

So your answer is 2(6x + 5 + 2y).

Find the given angle to the nearest degree.

Darina [25.2K]

Answer:

$\alpha=44\°$

Step-by-step explanation:

By definition, the tangent of an angle is the quotient between the side opposite the angle and the side adjacent to the angle

In other words:

$tan(\alpha) = \frac{opposite}{adjacent}$

In this triangle, the length of the side adjacent to the desired angle is 50, and the length of the opposite side is 48

So:

$tan(\alpha) = \frac{48}{50}\\\\tan(\alpha)= 0.96$

Finally

$\alpha =arctan(0.96)\\\\\alpha=44\°$

Let $x$ be the number of lower-level tickets sold, and $y$ the number of upper-level tickets sold.

Now, if the theater sells 350 tickets total, that means the number of lower-level and upper-level tickets that got sold should add up to 350, so one equation in the system is

$x+y=350$

You also know that the theater earns $10250 in sales, so if each lower-level ticket costs $35, and each upper-level ticket costs $25[/tex], this means $35x$ represents the amount of money made from selling lower-level ticekts, and $25y$ represents the amount of money made from selling upper-level tickets. You get the second equation in the system,

$35x+25y=10250$

So the system is

$\begin{cases}x+y=350\\35x+25y=10250\end{cases}$

Any one of the methods listed in the second part works in solving this system (though I'm not sure what "variable" refers to), but I think substituting involves the least work.

Solve the first equation for either variable; I'll choose $x$ .

$x+y=350\implies x=350-y$

Now substitute this into the second equation for $x$ , then solve for $y$ .

$35(350-y)+25y=10250\implies 10y=2000\implies y=200$

So 200 upper-level seats were sold. Meanwhile, since $x+y=350$ , this means

$x+200=350\implies x=150$

so that 150 lower-level tickets were sold.

To investigate whether or not sexism was present in the workplace, 48 male bank supervisors were each given a personnel file and

Volgvan

There is a clear bias. It is important however to not look at how many women got promoted with respect to men but which proportion of each subset got promoted. In the man files, 21/24 got promoted; this is a very high percentage, equal to 87.5%. Nonetheless, regarding women, 14/24 got promoted, 58,3%, barely over half of them. Hence, we conclude that there is a significant bias that favors male workers.

You fill the entire fish tank with water. Then you dump out some of the water. The volume of the water in the tank decreases by

lukranit [14]

Answer:

1. 6/10 – 2/5 =

Ans: 2/10, which can be reduced to 1/5.

2. If a tank is 5/8 filled with solution, how much of the tank is empty?

Ans: 3/8 of the tank is empty. Since the whole tank would equal 8/8, or 1, and 5/8 of it is filled, then that

means 3/8 of it remains empty.

3. 1/2 x 3/5 x2/3 =

Ans: 6/30, which can be reduced to 1/5.

4. 5/9 ÷ 4/11 =

Ans: 55/36. You cannot reduce this fraction any further.

5. Convert 27/4 to a decimal.

Ans: 6.75. This answer is arrived at by dividing 4 into 27.

6. Convert 0.45 to a fraction.

Ans: 45/100, which can be reduced to 9/20.

7. 4.27 x 1.6 =

Ans: 6.832

8. 6.5 ÷ 0.8 =

Ans: 8.125

9. 12 + 4.52 + 245.621 =
