Answer:

8.5.28492 cm/s

Step-by-step explanation:

We are given that

Radius of circular planter=11.7 cm

Time taken by bug =13.91 s

We have to find the speed of bug.

We know that

Speed =\frac{distance}{time}

Distance traveled by bug =2\pi r

Distance traveled by bug =2\times 3.14\times 11.7

Because \pi=3.14

Speed of bug=\frac{2\times 3.14\times 11.7}{13.91}=5.28224 cm/s

Hence, speed of bug=5.2822 4 cm/s

Answer:8.5.28492 cm/s

Find the value of X and the missing angle
GuDViN [60]

Answer:

x = 10

missing angle = 83°

Step-by-step explanation:

These are supplementary angles meaning they have a sum of 180°.

8x + 3 + 97 = 180

8x + 100 = 180

8x + 100 - 100 = 180 - 100

8x = 80

x = 10

Substitute the value for the variable.

8(10) + 3

80 + 3

83

Miles takes a 350-mile round-trip flight to visit his parents. To qualify for Gold status at Awesome
Vika [28.1K]

Answer:

Miles must travel a minimum of 22 times and a maximum of 36 times to achieve Gold status.

Step-by-step explanation:

Given that Miles takes a 350-mile round-trip flight to visit his parents, and to qualify for Gold status at Awesome Airlines, one must fly at least 7700 and less than 12600 miles each year, to determine how many times would Miles need to visit his parents each year to attain Gold status, the following calculation must be performed:

7700/350 = X

22 = X

12600/350 = X

36 = X

Thus, Miles must travel a minimum of 22 times and a maximum of 36 times to achieve Gold status.
