Answer:

Area = 64 + 16\pi

Step-by-step explanation:

Given

See attachment for the heart created

Required

The area of the heart

The area of the heart is the sum of the area of the square and the areas of the two semicircles.

From the attachment, we have:

s = 8in --- length of the square

d = 8in --- diameter of each semicircle

Calculate radius

r = 0.5 * d

r = 0.5 * 8 = 4in

The area of the square is:

Area = Length^2

A_1 = 8^2

A_1 = 64in^2

The area of the two semicircles is:

A_2 =2 * \frac{\pi r^2}{2} i.e. 2 multiplied by the area of 1

A_2 = \pi r^2

A_2 = \pi *4^2

A_2 = \pi *16

A_2 = 16\pi

So, the area of the heart is:

Area = A_1 + A_2

Area = 64 + 16\pi

Convert the timing into hours only:
11:15  = 11.25h
 9:45  = 9.75h
11:45 = 11.75h
 7:45  = 7.75h
10:45 = 10.75h

To find the average, we need to find the middle of these timing:
11.25 + 9.75 + 11.75 + 7.75 + 10.75 = 51.25

51.25 ÷ 5 = 10.25h = 10:15 am

------------------------------------------------------------------------
Answer: The average time it docks is 10:15 am.

Kobotan [32]

Answer:

90,60,75,135,30,0,180

Step-by-step explanation:

Given : Chris has decided to triple the amount of time he spends studying each night

To Find: . If the data set that represents the number of minutes he had previously spent studying each night is 30, 20, 25, 45, 10, 0, 60, which data sets represents the number of minutes he will now spend studying.

Solution:

Previous Hours : 30,20,25, 45, 10, 0, 60

Now since she decided to triple the amount of time she spends :

So,

30*3=90

20*3=60

25*3=75

45*3=135

10*3=30

0*3=0

60*3=180

So, the new set of data is 90,60,75,135,30,0,180

A = \frac{1}{2} × PQ × PR × sin P

   = 0.5 × 5.2 × 2.8 × sin50°

   ≈ 5.6 ( to 1 dec. place )
