At a baseball game, the ratio of Barons fans to Blue Sox fans is 8 : 3. If you know that at least 22,000 people are attending th

Stells [14]

When we look at ratios, we use for : against and add both to get the total in the set. therefore 8+3 = 11. divide the 22000 fans into 11 sections we have each section worth 2000 fans. The number of blue sox fans would be 3 x 2000 or 6000 fans with the remaining 16000 being baron fans.

How to work out Pythagoras Theoram

Vlad [161]

The Pythagorean Theorem works only with right angle triangles. There are three sides: Side A, Side B, and the hypotenuse.

The formula for the Pythagorean Theorem is: a^2 + b^2 = c^2

To find the answer (without the exponent), you should find the square root.

Now that we have the formula, let's apply it to a triangle:

90^2 + 95^2 = c^2 =

8100 + 9025 = 17125

Square root = 130.86252328302

130.86252328302 is the exact measure of the hypotenuse.

I hope this helped!

A car wash attendant counted the number of cars washed and the total amount of money earned. The company charged the same price

Bogdan [553]

The answer is m(n)= 11n
If you take the different of the money from 21 cars and 25 cars, you get 44 and since 21 and 25 is only a difference of 4, you’ll divide the 44 earned by the 4 cars washed to get $11 per car and then just make sure to use the correct variables

The focus of a parabola is located at (4,0), and the directrix is located at x =-4. Which equation represents the parabola?

Liono4ka [1.6K]

Answer:

Step-by-step explanation:

One of the important things to remember about parabolas is that the vertex is directly in between the focus and the directrix. Our focus is at (4, 0) and the directrix is at (-4, 0), so that means that the vertex (h, k) is at the origin (0, 0). Another important thing to remember is that the distance between either the vertex and the focus or the vertex and the directrix is the p value, the value that tells us how stretched or compressed the parabola is. Another thing to remember is that a parabola will always wrap itself around the focus away from the directrix. So here's what we know then:

Our parabola opens to the right, the equation for that is

$(y-k)^2=4p(x-h)$ ,

p = 4, and the vertex is (0, 0). Filling in the formula for the parabola using that info:

$(y-0)^2=4(4)(x-0)$ which simplifies a bit to

$y^2=16x$ and solving it for x:

$\frac{1}{16}y^2=x$
