What is 80% of blank games is 32 games

1 answer:

5 0

So basically you are saying that 80% of ____ games is 32 games.

So 32 is the 80% of the games played.

so we can divide 32 by 8, and that will give us 4 ( you might be confused why I did this, just be patient please)

so 4 is 10% of the games played.

We have to find out 20%, so we just multiply 4 by 2, which is 8

too find out 100%, we just add 80% and 20%, so 32 was 80%, and 8 was 20%, and 32 + 8 = 40

So the answer would be 40.

Solve the system of equations by elimination.

n200080 [17]

Answer:

Step-by-step explanation:

1. 2x - 9y = 23

2 x = 9 y + 23

y = (2 x)/9 - 23/9

2 x - 9 y - 23 = 0

2. 5x - 3y = -1

5 x + 1 = 3 y

y = (5 x)/3 + 1/3

5 x - 3 y + 1 = 0

I belive that should help you out a bit :D

2x^3-3x^2-11x+6 divide by x-3

Alexxx [7]

Answer: $2x^2+3x-2$

Step-by-step explanation:

You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.

Do $\frac{2x^3}{x}=2x^2$ . Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.

$2x^2*(x-3)=2x^3 -6x^2\\(2x^3 -3x^2-11x+6)-(2x^3-6x^2) = 3x^2-11x+6$

Now do $\frac{3x^2}{x} =3x$ . Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:

$3x(x-3)=3x^2-9x\\(3x^2-11x+6)-(3x^2-9x)=-2x+6$

Your final step is to do $\frac{-2x}{x} =-2$ . Write this -2 next to your other two parts

Multiply -2 by (x - 3) to get:

$-2(x-3)=-2x+6\\(-2x+6)-(-2x+6)=0$

Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:

$2x^2+3x-2$ times

Linda owns 4 shares of a certain stock. Yesterday the total value of her shares went down by 32 dollars. What was the change in

Annette [7]

Answer:

The value of each share decreased by $8.

Step-by-step explanation:

Number of shares of a certain stock Linda owned = 4

Total value of shares went down by = $32

So find the change in value of each share.

Solution:

Let the total value of each share in dollars be = $x$

Value of 4 shares in dollars will be = $4x$

The total value of shares went down by $32

So, new value of 4 shares = $4x-32$

New value of each share = $\frac{New\ value\ of\ total\ shares}{4}$

⇒ $\frac{4x-32}{4}$

Splitting the denominators.

⇒ $\frac{4x{{4}-\frac{32}}{4}$

⇒ $x-8$

Original value of each share in dollars was = $x$

New value of each share in dollars = $x-8$

Thus, we can see that the value of each share decreased by $8.

To input your angle measures in degrees, use the functions sind, cosd and tand, instead of sin, cos and tan. Zach stands at the

kramer

Answer:

about 2949 feet

Step-by-step explanation:

The geometry of the situation can be modeled by a right triangle. The height of the cliff can be taken to be the side opposite the given angle, and the distance to the coyote will be the side adjacent to the given angle. The relation between these values is the trig function ...

Tan = Opposite/Adjacent

<h3>setup</h3>

Filling in the known values, we have ...

tan(6°) = (310 ft)/(distance to coyote)

<h3>solution</h3>

Multiplying by (distance to coyote)/tan(6°) gives ...

distance to coyote = (310 ft)/tan(6°) ≈ 310/0.105104 ft

distance to coyote ≈ 2949.453 ft

The coyote is about 2949 feet from the base of the cliff.

The cost, in millions of dollars, for a company to manufacture x thousand speed boats is given by the function C(x) = 3x2 - 30x

nalin [4]

Answer:

5000

Step-by-step explanation:

In vertex form, the cost function is ...

C(x) = 3(x² -10x) +175 = 3(x² -10x +25) +175 -3(25)

C(x) = 3(x -5)² +100

The vertex is at x=5, so the cost function will be minimized when 5000 speed boats are produced.
