Answer: Addition
Step-by-step explanation: You can represent that as 10^5*10^-5
If you add the exponent values, you get 10^0 which is equal to 1. If you multiply them, you get 10^-25 which is wrong.

Answer:
Step-by-step explanation:
Question: 5 - 7(z+1) = 7(-9-3z)
We multiply the number in front of the bracket first, since that is multiplication.
--> 5 -7z -7 = -63 - 21z
--> -7z -2 = -63 - 21z
Now, we move all the z and all the numbers to each side.
--> -7z +21z = -63 +2
--> 14z = -61
--> z = -61/14
This cannot be simplified further, so z is -61/14.
Since 6/7 = ( 2*3 ) / ( 2*4 ) = 3/4 the least number of 6/8 pound bags will be 4.
Answer : 4
Answer:
285
Step-by-step explanation:
First find the area of the rectangle
A = l*w
A = 19*12 = 228
The find the area of the semicircle
A = 1/2 pi r^2
We know the diameter is 12 so the radius is half the diameter so 1/2 (12) = 6
A = 1/2 (3.14)(6)^2
= 1/2 (3.14) (36)
= 56.52
Add the two areas together
225+56.52
284.52
Rounding to the nearest whole number
285
