How much of a spice that is 3% salt should be added to 175 ounces of a spice that is 6% salt in order to make a spice that is 5%

kozerog [31]

<h3>Answer:</h3>

87.5 ounces

<h3>Explanation:</h3>

There's a cute "X-diagram" tool that can be used for solving mixture problems of all kinds. (See the attachment.) The numbers on the left represent the percentages of the constituents of the mix. The number in the center is the desired percentage in the resultant mix. The numbers on the right in the X are the differences along the diagonals. (6-5=1, 5-3=2)

These are also the proportions of the constituents in the final mix. That is, there are 2 parts of spice that is 6% salt for each 1 part of spice that is 3% salt. So, we need half as much of the latter as the former.

Half of 175 ounces is 87.5 ounces, the amount of 3% spice that is needed.

_____

If you really want to write an equation, you can let x represent the amount of 3% spice needed. Then the amount of salt in the mix is ...

... 175×6% +x×3% = (175+x)×5%

Dropping the percent symbols and eliminating parentheses, we have

... 1050 +3x = 875 +5x

... (1050 -875) = (5x -3x) . . . . . add -875-2x

... 175/2 = x = 87.5 . . . . . . . . . . divide by the coefficient of x

Answer:

Area is 582 feet squared

Step-by-step explanation:

So, it suggests you break the shape apart, which is exactly what we can do to solve this problem.

We know that the longest side is 38ft, but to find the remaining length of the top, we will subtract 21 from 38.

So: 38ft - 21ft = 17ft

Now we can break the shape. The square will be 21 by 18 ft, and the remaining rectangle shape will be 12 by 17ft.

For the area, we'll start with the square. The formula for area is length times width: A=LW

For the square, we have the length, 21, and the width 18ft. All we have to do is multiply them:

21 * 18 = 378ft. squared

Now we can move on the rectangle, which has a length of 17ft, and width of 12ft.

12 * 17 = 204ft. squared

Last step! We add our areas together to get the entire shape's area. So..

378ft. + 204ft. = 582ft. squared

Good luck :P
