Agame has a circular playing area in which you must hit a ball into a circular hole. the area of the playing area is 16ft2. the hole has a diameter of 1 ft. what is the probability of hitting a ball into the circular hole?
express your answer as a percentage rounded to the nearest tenth.

Step-by-step explanation:

we know that

To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area

Let

x ----> the area of the hole

y ----> the area of the playing game

so

we have

Find the area of the hole

The area of the circle (hole) is equal to

we have

----> the radius is half the diameter

assume

substitute

Find the probability

we have

substitute

Convert to percentage

Round to the nearest tenth

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
