If 16 ounces feeds 80 and you need to find how many 12 ounces feeds, you need to find how many 1 ounce feeds. so take 80 and divide by 16, you get 5 birds per ounce. now since it is 5 per ounce and you have 12 ounces you multiply 5 by 12 and get 60. Hope this answers you question.

If you look at the figure, you will see that there is an angle opposite each angle whose value we have. Therefore, just do (3x+2x+x)·2= 6x·2=12x

Now, 360/12=30°

x=30°

Tyler baked 702 cookies he sold them in boxes of 18 after selling all of the boxes of cookies for the same amount of each he ear
jenyasd209 [6]

Keywords:

<em>Cookies, boxes, sale, profit, unit cost </em>

For this case we have to bake an amount of 702 cookies, which were distributed in boxes of 18 for sale. Selling each box at the same price earned a profit of 136.50 dollars, you want to know the unit cost of each box of cookies.

Let "x"be the number of boxes of cookies:

So, to know the number of boxes we divide 702 cookies among 18:

x = \frac {702} {18}\\x = 39

So, we have Tyler sold 39 boxes of cookies

Now, let "y" be the cost of each box of cookies, to know the unit cost or sale price of the cookie boxes, we divided 136.50 dollars among 39 boxes of cookies, then:

y = \frac {136.50} {39}\\y = 3.5

Thus, the cost of each box was 3.5 dollars.

Answer:

The cost of a box is 3.5 dollars

mash [69]

Answer:

The correct option is a.

Step-by-step explanation:

The general form of a quadratic regression equation is

y=ax^2+bx+c                         ..... (1)

Using graphing calculator we get

a=-0.143393\approx -0.143

b=0.59525\approx 0.595

c=2.82964\approx 2.830

Substitute these values in equation (1) to find the quadratic regression equation for this data set.

y=-0.143x^2+0.595x+2.830

Therefore the correct option is a.
