Representing 3 and one tenth as decimal by 3.1
<u>Step-by-step explanation:</u>
Here 3 is the whole number.
1 tenth is nothing but 
.
= 0.1
When we write numerals with tenths using the decimals we can use a decimal point also the tenths positioned to the right of the decimal point. The tenth place is denoted as immediately right to the decimal point.
So it is represented as 3.1.
Using the Pythagorean theorem we can solve for x.
x^2 + 6^2 = 10^2
Simplify:
x^2 + 36 = 100
Subtract 36 from both sides:
x^2 = 64
x = √64
x = 8
3k²+11k+6, or (k+3)(3k+2), which is the 3rd one. :)
Answer:
57
Step-by-step explanation:
because all the angle of a triangle add up to 180
180-63-60=57
Answer:
256
Step-by-step explanation:
sum of the first n odd number is n^2
if we want to find the sum of of 1 thru 31
to find out how many numbers that is
(1+31)/2 = 32/2 =16
there are 16 numbers
n^2 =16^2 =256
