Answer:

About 9.1 yards tall.

Step-by-step explanation:

So, we can draw the right triangle shown below:

We want to find h.

Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:

$\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}$

So:

$\displaystyle \tan(20)=\frac{h}{25}$

Therefore:

$\displaystyle h=25\tan(20)$

Use a calculator. Ensure your calculator is in the correct mode (degrees mode):

$h\approx 9.1\text{ yards}$

The goal post is around 9.1 yards tall.

write the ratio as a fraction in simplest form. with whole numbers in the numerato and denominator. 40g : 64g

babunello [35]

Answer:

$\frac{5g}{8g}$ OR 5g : 8g

Step-by-step explanation:

Also a ratio can also be represented by a fraction; $\frac{40g}{64g}$

So to make the ratio to the simplest form we have to divide by a number that can divide both number.

40g : 64g

We can start dividing by 2 which will give us;

20g : 32g

$\frac{20g}{32g}$

Now we can divide by 2 again since it can divide both numbers which will give us;

10g : 16g

$\frac{10g}{16g}$

We can still divide by 2 since it can divide both numbers which will give us;

5g : 8g

$\frac{5g}{8g}$

Since no numbers can divide 5 and 8 equally that is our answer.

Also, $\frac{5g}{8g}$

Tannin and Dax bought a new video game for $48 to use the coupon for 25% off how much would the game cost if they paid full pric

olchik [2.2K]

Answer:

$64

Step-by-step explanation:

After using a 25% discount coupon, they paid 48 for the video game.

It means, <em>which number, decreased by 25%, would give us 48?</em>

<em />

First, 25% to decimal is:

25/100 = 0.25

Now, if we let the original price be "x", we can say:

x decreased by 0.25 of x would give us 48

Translating this to algebraic equation gives us:

x - 0.25x = 48

Now, we solve this:

$x - 0.25x = 48\\0.75x=48\\x=\frac{48}{0.75}\\x=64$

If they paid full price, the video game would cost $64
