Step-by-step explanation:
7 = √49
8 = √64
So any positive integer between 50 to 63, both inclusive, have a square root between 7 and 8.
Answer:
x=500
Step-by-step explanation:
7/10=350/x
cross-multiply by multiplying 350 to 10 and multiply 7 to x.
example:
7•x
350•10
7x=3500
divide both sides by 7

Step-by-step explanation:
the sequence is arithmetic due to the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
Then :
a(n) = 15+(n-1)-4

Answer:
35%
Step-by-step explanation:
easy way to remember: 
= 
= 35%
Because a triangle's angles need to equal 180, you can subtract 100(30+70) and you will get 80. So 80 will be your third angle.
