Emma enjoys flying kites. her red kite has a maximum altitude of 117.46 meters, and her black kite has a maximum altitude of 362
7nadin3 [17]
You have to convert 117.46 meters to feet. so you know that 0.3048 meters is 1 foot.  

117.46 / 0.3048= 385.37feet red kite
now you can simply subtract
385.37-362.26=23.11ft
the answer is, the red kite has an altitude 23.11 feet higher then the black kite.

Select the assumption necessary to start an indirect proof of the statement. If 3a+7 < 28, then a<7.
pashok25 [27]
When applying indirect proofs, we assume the negation of the conclusion is true, and show that this assumption would lead to nonsense, or contradiction.

In our case we assume a is not smaller than 7, that is we assume a≥7.

a≥7 then, multiplying both sides by 3:
3a≥21, then, adding both sides 7:

3a+7≥28,

which is a contradiction because 3a+7 is smaller than 28.

So our assumption is wrong, which means the opposite of it is correct.


Answer: assume a≥7
