Answer:

  D.  210

Step-by-step explanation:

If b is the number of boys in the choir, the ratio of boys to girls is ...

  b/150 = 7/5

  b = 150(7/5) = 30(7) = 210

There are 210 boys in the choir.

Hunter-Best [27]

Answer: 100 boxes

Step-by-step explanation:

Hi, since 1 ton = 2,000 lbs

We have to divide 10lbs by 2000 to convert the lbs in tons.

1t/2000lb = xt / 10lb

10 /2000=0.005

0.005 ton = 10 lbs (1 bag)

Each box has 4 bags

0.005 ton x 4 = 0.02 ton

So each box weights 0.02 ton

Since we need 2 tons.

Using proportions:

0.02t/1 box= 2 t / x boxes

x = 2 / (0.02/1)

x = 100 boxes  

Feel free to ask for more if needed or if you did not understand something.

<span>If you were asked to express the weight in ounces of a ladybug in scientific notation, would the exponent of 10 be positive or negative?

Unless it was used otherwise. </span>
