Answer:
I think it is d
Step-by-step explanation:
The pythagroean theorem says a² + b² = c² and we're given a and c in this case
12² + b² = 13²
144 + b² = 169; subtract 144 from both sides
b² = 25; square root both sides
b = 5 so the length of side AB is C) 5
Answer:
-64 is the 26th number
it's an arithmetic sequence because the difference between the number is constant : -3
they are all -3 in difference
Step-by-step explanation:
an = a1 + (n-1)d
an = the nᵗʰ term in the sequence
a1=the first term in the sequence
d=the common difference between terms
-64 = 11 + (n - 1)-3
-64=11 -3n+3
-78 = -3n
n = 26
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.
Hope this helps!
