Find the probability that the dart lands in the shaded circular region. The radius of the dartboard is 4 in, and the radius of t

PilotLPTM [1.2K]

Answer: The required probability is 0.25.

Step-by-step explanation:

Since we have given that

Radius of the dartboard = 4 in

Area of the dartboard is given by

$\pi r^2=3.14\times (4)^2=3.14\times 16=50.24\ in^2$

Radius of the shaded region = 2 in

Area of shaded region is given by

$\pi r^2=3.14\times (2)^2=12.56\ in^2$

So, the probability that the dart lands in the shaded circular region is given by

$\dfrac{12.56}{50.24}=0.25$

Hence, the required probability is 0.25.

A craft store buys 50 yards of satin ribon for $12.50. The store sells the ribbon by the foot. A customer can purchase 5 feet of

amm1812

Answer:

$8.1

Step-by-step explanation:

Convert 45 yards of ribbon to feet through proper conversion factor.

(45 yards)(3 ft / 1 yard) = 135 feet

Divide this number by 5 to determine the number of 5-ft ribbon that customers can purchased.

n = 135 ft / 5 ft = 27

Then, multiply by $0.80.

R = (27)($0.80) = $21.6

The profit is equal to $21.6 and $13.50,

P = $21.6 - $13.50 = $8.1

Answer: $8.1

There are 45 students who play a woodwind instrument in the school band. Of these, 18 play the saxophone. What percent of these

Mashutka [201]

Answer:

40% students play the saxophone.

Step-by-step explanation:

Given:

Total Number of students who play woodwind instrument = 45

Number of students who play saxophone = 18

We need to find the percent of students who play saxophone.

Solution:

Now we can say that;

To find the percent of students who play saxophone we will divide Number of students who play saxophone by Total Number of students who play woodwind instrument and the multiply by 100.

framing in equation form we get;

percent of students who play saxophone = $\frac{18}{45}\times100= 40\%$

Hence 40% students play the saxophone.
