U have to use Pythagoras theorem to solve this.. (adjacent)^2+(opposite)^2=hypotenuse^2
looking at the question,
the hypotenuse =15ft
opposite =12ft
adjacent =???
adjacent^2+(12)^2=15^2
a^2+144=225
group like terms
a^2=225-144
a^2=81
introduce square root to both side
root a^2=root81
a=9ft
therefore, the answer is 9ft.
Answer:
d. The common ratio is 1.1
Step-by-step explanation:
To see if the data has a common ratio or common difference, we have to see if the division between them is equal(common ratio), or if the difference between them is equal(common difference).
In this case, since
, it has a common ratio.
To find it, we divide consecutive terms. For example:

So the correct answer is:
d. The common ratio is 1.1
Divide: 7/3: 1/5= 7/3· 5/1= 7 · 5/3 · 1= 35/3
Answer:
False
Step-by-step explanation:
if x=4 the answer would not be -9
x+51 would add up to 55
so it would be : 4+51=55
now if we wanted the answer to be -9 , x would have to be different
-60+51=-9
but in this case x is no -60, it's 4, so no this statement is false.
