Salim bought 31/4kg oranges,151/2kg pineapples and 103/4kg bananas. find the total weight of fruits. if he used 23/4oranges ,121/4kg pineapples and 61/2kg bananas to make juice in a day then find the weight of fruits left?

109 kg total

57 3/4 after

Step-by-step explanation:

31/4 orange

302/4 pineapples

103/4 bananas

436/4 total=109

436/4-205/4=231/4=57 3/4

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
