Answer:
The area of the triangle is 10.92 cm².
Step-by-step explanation:
The formula for the area of a triangle is
where b is the length of the base and h is the height. We know that b = 2.8 and h = 7.8, so you would substitute into the formula:
cm²
Answer:The slope is 1
Step-by-step explanation:
y2-y1=-3
x2-x1=-3
put them into a fraction and the slope is 1 because -3/-3=1
Step-by-step explanation:
% calculations are totally easy, if you remember to always find and the use 1%.
100% = $2.85
1% = 100%/100 = 2.85/100 = 0.0285
the price difference was
2.91 - 2.85 = $0.06
how many % are these $0.06 compared to yesterday's price ?
that is how many times 1% can fit into this number.
0.06 / 0.0285 = 2.105263158...%
so, rounded this is 2.1%
A break even problem is found when you calculate starting a buisieness
so lets ssay you have to buy 3 coppy machines and each machine costs 2000 dollars,
the people who want to use your coppy machines have to pay $0.40 per page
so you have spent 6000 dollars already
when you break even, it is when your earnings equals your expenditure (how much you earned equals how much you paid)
