There are 99 males and 121 females participating in a marathon. What percent of the participants are female?​
ioda

To do this, we first want to see how many participants there are in total by adding both males and females.

99+121=220

Now we know that there were 220 total participants, but only 121 were females.

This allows us to set up the fraction 121/220= the percent female.

\frac{121}{220} =0.55

or 55%

Answer:

36.48 cm²

Step-by-step Explanation:

If you take a careful look at the figure given, you'd realise that the area of the shaded portion is actually created by 2 overlapping quarter circle.

The area of the shaded portion = Area of Square - Area of Unshaded part

Area of square = s² = 8² = 64 cm²

Area of the Unshaded portion = 2(Area of Square - Area of Quarter Circle)

= 2(s² - ¼*πr²)

Where, radius (r) = s = 8 cm, take π as 3.14

Area of unshaded part = 2(8² - ¼*3.14*8²)

= 2(64 - ¼*3.14*64)

= 2(64 - 1*3.14*16)

= 2(64 - 50.24)

= 2(13.76)

Area of unshaded part = 27.52 cm²

Area of shaded part = Area of Square - Area of Unshaded part

Area of shaded part = 64 - 27.52 = 36.48 cm²

Solve for F.<br> 3(6-f)-4=3f-4
Alinara [238K]

Answer:

F=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(6−f)−4=3f−4

(3)(6)+(3)(−f)+−4=3f+−4(Distribute)

18+−3f+−4=3f+−4

(−3f)+(18+−4)=3f−4(Combine Like Terms)

−3f+14=3f−4

−3f+14=3f−4

Step 2: Subtract 3f from both sides.

−3f+14−3f=3f−4−3f

−6f+14=−4

Step 3: Subtract 14 from both sides.

−6f+14−14=−4−14

−6f=−18

Step 4: Divide both sides by -6.

−6f−6=−18−6f=3

Answer:

f=3
