Answer:

168cm^3

Step-by-step explanation:

Q to P is going to be 3cm. it is identical to the length T to U.

R to T , W to Q, S to U is going to be identical to P to V. P to V has been identified as 12 cm.

in the middle of the shape, there are 4 identical triangles. the height time length will give us the area of that one shape:

e.g for shape P to V to W to Q and back to P is one rectangle. the length is 12 cm and the width is 3 cm.

12 x 3= 36

36cm^3 is one rectangles surface area, we have 4 identical triangles that means we need to times 36 by 4.

so 36x4=144.

now on the left and right side, we have two squares. on the right, we have T to U to V to W back to T this has the height of 3 width of 4 then we do 3 X 4 which is 12, we times it by 2 because we have two identical squares.

12 X 2=24

finally we add 24 and 144 = 168cm^3.

hope this helps :)

You want to find the number of visits IN BETWEEN 12:30 PM and 6:45 PM

there some visits already recorded before 12:30. These visits are visits that you want to exclude but are included in the TOTAL visits

Before 12:30 the website has 1200 visits and at 6:45 the website has 14000.

In an optical fibre, the power drops by a factor of 10 approximately every 30 km. If the transmit power is 0. 35 W, how far will
IgorC [24]

Answer:

  • 30000 km

Step-by-step explanation:

First convert the transmit power into μW, considering 1 W = 1000000 μW:

  • 0.35 W = 0.35*1000000 μW = 350000 μW

Find how many factors of 10 the power dropped:

  • 350000 / 350 = 1000

Find the distance:

  • 1000*30 km = 30000 km
