John is a quarterback. This year, he completed 350 passes, which is 70%, percent of all the passes he's attempted this year.
PolarNik [594]
Let all attempted passes = x

70% of x = 350

(70/100)*x = 350

7x/10 = 350

7x = 350 * 10

x = (350 * 10) /7

x = 500

John attempted 500 passes.

If the parabola y - 8 = 3(x - h)² has the line x = 5 as its axis of symmetry, find h.
Goshia [24]
h = 5 because if you added 8 to the other side of the equation, then the equation would be in vertex form, where the opposite of h, and the value of k (8) is your vertex. So, we know that the x-value of the vertex is also the axis of symmetry, so the axis of symmetry is also the x-value of the vertex, or h. 

Hope this helps! :)

What is 9.1 divided by 3576 and than the answer rounded to the nearest whole number?
Bumek [7]
9.1 is less than half of 3576, so it's going to round down to 0. (mental math)

<em>I'm not sure if you were also asking for the actual value because of the wording, so here it is if you need it</em>.

As a fraction, \frac{9.1}{3576}=\frac{91}{35760}.
(multiply both the top and the bottom by 10)

As for the actual decimal value, it's something like 0.0025447....You can find this out using long division (you're going to have to know the multiples up to 10 of 3576, so list those off to the side) or simply a calculator. As for handling the decimal, just divide into the 9.1 like a normal number (only the digits are important when you're doing the long division) and bring up the decimal point when you're done. You might also need to use zeroes as placeholders. (9.1 = 9.10000...)

What is the perimeter of this equilateral triangle? <br> Choices <br> 4<br> 20<br> 40<br> 60
aliina [53]

Answer:

60

Step-by-step explanation:

If it is an equilateral triangle the sides are equal

24-x = 5x

Add x to each side

24-x+x = 5x+x

24 =6x

Divide by 6

24/6 =6x/6

4 =x

Each side is 5x or 5*4 = 20

Add the 3 equal sides

20+20+20 = 60

The perimeter is 60
