3.82 E+7 is just an <u>engineering format</u>, another way to write it will be 3.82 x 10⁷ in <u>scientific format</u>, or just 3.82 x 10000000 <--- notice, seven zeros.
and the product of the above is just 38200000, or <u>standard form</u>.
7 * 2.9
(7 * 2) + (7 * 0.9) = 20.3 <==
Answer:
see below
Step-by-step explanation:
If we let X represent the number of bagels produced, and Y the number of croissants, then we want ...
(a) Max Profit = 20X +30Y
(b) Subject to ...
6X +3Y ≤ 6600 . . . . . . available flour
X + Y ≤ 1400 . . . . . . . . available yeast
2X +4Y ≤ 4800 . . . . . . available sugar
_____
Production of 400 bagels and 1000 croissants will produce a maximum profit of $380.
__
In the attached graph, we have shaded the areas that are NOT part of the solution set. (X and Y less than 0 are also not part of the solution set, but are left unshaded.) This approach can sometimes make the solution space easier to understand, since it is white.
The vertex of the solution space that moves the profit function farthest from the origin is the one we are seeking. The point that does that is (X, Y) = (400, 1000).
The number of pounds of copper in 120 pounds of brass is = 78 pounds of copper
<h3>Calculation of number of pounds of copper</h3>
The percentage of copper in the brass = 65%
Therefore the quantity of copper in the brass = 65/100= 0.65 pounds
This means that 1 pound brass contains = 0.65 pounds of copper
The quantity of copper in 120 pounds of brass = 120 * 0.65
= 78 pounds of copper.
