Answer:

768000

Step-by-step explanation:

From 1900 to 2020 = 120 means that it doubles 4 times ( once every 30 years)

=> 48000 * 2 ^ 4 = 768000

Number #7 please I need help on it
Rom4ik [11]
Answer: 104$

Explanation:

She is paid 7$ for each of the first 7 demo

And she is paid 11$ for each demo over the 7 demo

But she did 12 demo, which mean the first 7 demo she got paid 7$ each and for the last 5 demo she got paid 11$ for each demo.

(7 • 7) + (11 • 5)
= 49 + 55
= 104$

Explain how to subtract 247 from 538
Licemer1 [7]
For this case we have the following operation:
 538 - 247
 To subtract both numbers we must follow the following steps:
 1) Subtraction is done from left to right:
 2) We subtract the first digits:
 8 - 7 = 1
 3) We subtract the second digits:
 3 - 4
 Since 4 is greater than 3 then we add a digit to 3 and accumulate it for the next subtraction:
 13 - 4 = 9
 4) We subtract the digit accumulated in the previous subtraction to the following number:
 5 - 2 - 1 = 2
 Finally the result is:
 538 - 247 = 291

The top box has a length of 6 yards
cricket20 [7]

Answer:

42 yd²

Step-by-step explanation:

Area of a rectangle = width x length

lateral surface area is the area of the sides only

So the difference between the total surface area and the lateral surface area would be the surface area of the ceiling and floor (top and bottom).

area of floor and ceiling = 2(3.5 x 6) = 42 yd²

Or, we can calculate the total surface area and lateral surface area, then find the difference:

total surface area = 2(3.5 x 4.2) + 2(4.2 x 6) + 2(3.5 x 6) = 121.8 yd²

lateral surface area = 2(3.5 x 4.2) + 2(4.2 x 6) = 79.8 yd²

difference = 121.8 - 79.8 = 42 yd²
