Nostrana [21]

Answer:

Latest time for start hiking = 4:57 PM

Step-by-step explanation:

Given:

Time of sunset = 9:26 P.M

Time taken for hiking = 3 hours and 3 minutes (03:03)

Time taken for set up = 1 hour and 26 minutes (1:26)

Find:

Latest time for start hiking

Computation:

Latest time for start hiking = Time of sunset - Time taken for set up - Time taken for hiking

Latest time for start hiking = 9:26 - 1:26 - Time taken for hiking

Latest time for start hiking = 8:00 PM - 03:03

Latest time for start hiking = 7:60 - 03:03

Latest time for start hiking = 4:57 PM

A phone cost 199$ and is on sale for 25% off. What is the sale price?
andrey2020 [161]

Answer:

<em>See below.</em>

Step-by-step explanation:

Divide the percentage by 100 to turn it into decimal form.

\frac{25}{100}=.25

Then, multiply the percentage by the original amount.

199*.25=49.75

Last, subtract that from the original price.

199-49.75=149.25

<em>Answer: </em>149.25

A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)
Hatshy [7]

The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

C=2\pi r

putting the values

75.36 = 2*3.14*r\\75.36 = 6.28r

Dividing both sides by 6.28

\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm

The area of circle is given by:

A = \pi r^2

Putting the values

A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2

Hence,

The area of flying disk is 452.16 square centimeters

Keywords: Circle, area
