Luna ray has 1 orange pick for every 2 green picks.How many green picks does Luna have if she has 12 total picks?
Lana71 [14]

Answer:

8 green picks

Step-by-step explanation:

Since this problem is a ratio that also gives a total, setting up equivalent ratios in a table with the total would be a good way to find the answer.  Since there is 1 orange pick for every 2 green picks and there are a total of 12 picks, we can set up the following:

Orange 1 2 3 4 5

Green 2 4 6 8 10

Total 3 6 9 12 15

You can see from the table, that when there are 12 total picks, 4 of them are orange and 8 of them are green.

1. Which of the following will simplify to the<br> correct solutions of y = 2x2 + 5x - 7?
natka813 [3]

Answer:

Option B

Step-by-step explanation:

Given quadratic equation is,

y = 2x² + 5x - 7

By comparing this equation with y = ax² + bx + c

a = 2, b = 5 and c = -7

Solution of the polynomial (2x² + 5x - 7) can be determined by the quadratic formula,

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Substitute the values of a, b and c.

x=\frac{-5\pm \sqrt{5^2-4(2)(-7)}}{2(2)}

   =\frac{-5\pm \sqrt{25+56} }{4}

Therefore, Option B will be answer.
