I'm pretty sure it would be 4 5/6 - 3 2/3 = 1 1/6.
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$
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
Y/b=11 that’s a turned around phase question
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
