Answer:
using the pythagoras theorem the answer is a=3
Step-by-step explanation:
basically in a right angled triangle a² + b² equals c². in this equation c is the number on the hypotenuse (the line opposite the right angle)
and 4 could be a or b it doesnt make a difference so I'll call it b.
because we have c² and b² we work backwards like this:


because 9 is a², we must find the square root to find <em>a</em>

so a equals 3
Answer:
287
Step-by-step explanation:
400+10=410
(70:100)*410
(70*410):100
28700:100 = 287
Answer:
Step-by-step explanation:
a93 = 93 + 2(52 − 1)
a93 = 93 + 2(52 + 1)
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
Originally 52 - Get rid of the first 2
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
2 each week. - Annoying. That doesn't help.
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
We're not buying any new ones in the first week, so purchases are one down.
a93 = 52 + 2(93 − 1)
I think we made it.
45÷[(2×4.7)-4.4]×6 is where you would place them each
