this triangle has 3 sides one is 12, lets call this side a²
another side is 72, lets call this side c²
this triangle must follow Pythagoras therom if it is right angled, that is a²+b²=c²
where a and b are the two shorter sides and c is the longest side (called the hypotenuse) opposite the right angle
to find the last side you do 72² - 12² = 5040
but it is the square root of 5040 which is 70.99 (two decimal places) if you want it in decimal form, if you want it in surd form it is √5040
Hello!
Let's think about the denominators we have. A seventh goes on forever in no specified order. A fifth an a fourth have set decimal values, 0.2 and 0.25, so they are not repeating decimals. A ninth is 0.111111..., it repeats like this forever in a specified order. Therefore, 2/9, or 0.222222...., would be a repeating decimal.
Therefore, our answer is 
.
I hope this helps!
Answer:
20
Step-by-step explanation:
You use the distributive property.
Distribute the 2 to whatever is inside the parentheses. (You will multiply)
4×2=8
2×6=12
Substitute the answers above into the parentheses.
(8+12)=20
Answer: 145.8
Step-by-step explanation: you have to divide 45 and 25 to get 1.8, then you get 81 and you multiply 81 x 1.8 to get your answer.
Well 3 3/8 as a decimal is 3.375 and 1 5/6 as a decimal is 1.8333333333 and if you add those its <span>5.208333333</span>.
