Answer:
the fifth number is 11
Step-by-step explanation:
8,11,13 and 17, x
the mean is =12 ( which means the sum of the terms divided by the numbers of terms )
to find the mean :
(8+11+13+17+x)/5 =12
5*12=49+x
60-49=x
x=11
Answer:
p : q : r = 10 : 4 : 3
Step-by-step explanation:
Expressing the ratio in fractional form
=
( cross- multiply )
4r = 3q ( divide both sides by 4 )
r =
q =
× 2 = 
Then
p : q : r
= 5 : 2 :
( multiply all parts by 2 )
= 10 : 4 : 3
The answer should be 1 1/4
Answer:
I don't have a clue
Step-by-step explanation:
I believe the answer would 5 blocks
If you go 3 blocks East and 4 north, they are like the straight sides of a triangle, so to find the diagonal distance, or the shortest distance, you would find the diagonal side of a triangle it is
A squared + B squared = C squared
So 3x3 = 9
And 4x4 = 16
16+9=25
And the square root of 25 is 5
Please correct me if I am wrong and have a good day
