Answer:

Start: Brown feather % is  97% Grey feather % is 3%

End: Brown feather % is  19% Grey feather % is 81%

Step-by-step explanation:

Start:

There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7

divide each number by 7(679/7 and 21/7)

and you get 97 and 3 which will be your percentages

End:

There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4

divide each number by 7.7(140/7.4 and 600/7.4)

and you get about 19(rounded) and about 81(rounded) which will be your percentages

Hope this helps!!!

The millers are going to put a pool in their backyard this summer. The pool will have a depth of 5 feet, and the dimensions show
erica [24]

Answer:

D : 510 units

Step-by-step explanation:

NOTE:

Something to consider when solving problems like this is to break the large shape down into smaller, more managable shapes. So for this problem, you can break down this irregular shape into two rectangles. This will make solving problems similar to this easier in the future :)

WORK:

I broke down this shape into two rectangles with the following dimensions:

- 12 meters by 5 meters

- 3 meters by 14 meters

You also know that the depth has to be 5 feet (the problem itself did not account for differences in feet and meters, as when I converted the 5 feet to meters and solved that way, none of the answers were correct)

Using this information, you can now solve for the volume of each of the rectangles

12*5*5 = 300 units

3*14*5 = 210 units

Then, you simply add the two volumes together to find the total volume needed to fill the pool which equals

510 units

Can anyone help me with inverse function please? ​
12345 [234]

{h}^{ - 1} oh(x) = x \\  {h}^{ - 1} (4x + m) = x \\ 2k(4x + m) +  \frac{5}{8}  = x \\ 8kx + 2km +  \frac{5}{8}  = x

k and m must satisfy 8k = 1 mean k = ⅛

and 2km+⅝=0 mean m = -5/2
