Pretty, pretty, pretty please help!!!Which proportion models this problem?

1 answer:

8 0

8 of 19 players said that they had 2 or more siblings.

8 out of 19 is equal to what out of 570

8/19 = x/570

This proportion can be written in different ways.

8/19 = x/570 cross multiplies to 19*x = 8*570

The task is to find a proportion among the answer options that cross multiplies to the same equation.

Option C is x/570 = 8/19. That cross multiplies to 19*x = 8*570 and is the correct answer.

$\bf 16)\\\\
V=\pi r^2 h\implies \cfrac{V}{\pi h}=r^2\implies \pm\sqrt{\cfrac{V}{\pi h}}=r\implies +\sqrt{\cfrac{V}{\pi h}}=r

x^2+6x-7=0\qquad 
\begin{cases}
-1\cdot 7=&-7\\
-1+7=&6

x=

$\bf -------------------------------\\\\
(x+3)^2=16\implies x+3=\pm\sqrt{16}\implies x+3=\pm 4

A nursery owner buys 5 panes of glass to fix some damage to his greenhouse. The 5 panes cost 12.75$. Unfortunately, he breaks

igomit [66]

Answer:

$5.10

Step-by-step explanation:

The owner buys 5 panes of glass for $12.75. So to find the cost of 1, we need to divide the total cost by the amount of planes. In this case, 12.75 divided by 5. This gives you $2.55 per plane. And since he is buying 2 more, we would multiply the cost of the plane (2.55) by the amount we are buying (2). So we do 2.55 X 2 and we get $5.10
