14 trout out of 50 total fish. The total amount of fish in the lake is 7500. Let’s make this into a proportion.

14/50=x/7500

x represents how much trout is in the lake, we don’t know yet, but we’ll find out.

First, cross multiply.

14*7500=105000
50*x=50x

Now let’s turn this into an equation.

50x=105000
Divide both sides by 50
50x/50=x
105000/50=2100

x=2100
Out of the 7500 fish in the lake, 2100 were trouts.

nadezda [96]

Answer:

60º

Step-by-step explanation:

Label the radii OB and OC where AB and AC are tangents. OB and OC are 4.5 cm as they are both radii. Then we can see that OBA and OCA are both right triangles with OBA=OCA=90º. OAB=OAC=30º because the side lengths fit the criteria for a 30-60-90 triangle. OAB+OAC=60º

On every sale he makes, Bill earns a commission. On a bed he sells for $591, Bill earns a $43 commission. Find the percent commi
user100 [1]

The percent of commission is 7.3% to the nearest tenth of a percent

Step-by-step explanation:

The given is:

  • Bill earns a commission on every sale he makes
  • He sells a bed for $591 and earns a $43 commission

We need to find the percent commission

To find the percent of commission divide the commission by the selling price and multiply the answer by 100%

∵ His commission is $43

∵ The selling price is $591

∵ The percent of commission = \frac{commission}{selling price} × 100%

∴ The percent of commission = \frac{43}{591} × 100%

∴ The percent of commission = 7.2758%

- Rounded it to the nearest tenth percent

∴ The percent of commission = 7.3%

The percent of commission is 7.3% to the nearest tenth of a percent
