B but I may be wrong but I hope I heped
Change the dimensions to numbers of 0.5 inches: 3.5 is 7×0.5, 2.5 is 5, 1.5 is 3. The number of cubes needed is 7×5×3=105.
The total weight is 2 1/2 lbs
Rock A is 1/7 of the total weight....so it is 1/7 of 2 1/2 lbs..." of " means multiply
1/7 * 2 1/2 =
1/7 * 5/2 =
5/14 lbs <==
Answer:
$ 10¹¹.
Step-by-step explanation:
From the question given above, the following data were obtained:
1 computer programmer makes roughly $ 10⁵ yearly.
Thus, we can obtain the total amount made by 10⁶ programmers yearly as illustrated below:
1 computer programmer makes roughly $ 10⁵ yearly.
Therefore, 10⁶ programmers will make = 10⁶ × $ 10⁵ = $ 10¹¹
Thus, total amount made by 10⁶ programmers yearly is $ 10¹¹.
1/2a - 4
Add 4 to both sides.
1/2a = 4
Divide both sides by 1/2.
a = 8
