Hope this helps!
<u>Answer</u>
C. 4 + 6
D. 3.15151515.. + 4.6
E. √64 × √25
<u>Explanation</u>
A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.
π×6 = 6π ⇒ can not be written as a rational number.
√3 + √5 ⇒ the sum of two irrational numbers can not be rational.
4 + 6 = 10. Ten is a rational number. it can be written as 10/1
3.15151515.. + 4.6 = 104/33 + 23/5
= 1279/165
√64 × √25 = 8×5=40 This can be written as 40/1
X / 6/7 is 3 2/5. First, concert the numbers to decimals for simplicity sake, and you get x/.857 = 3.4. Multiply both sides by .857 to get x alone and you get x ≈ 2.9143
Two ways ∴
Fraction: 1 12/100
Decimal: 1.12
Answer:
208
Step-by-step explanation:
8*8=64
9*8/2=36
36*4=144
144+64=208
have a nice day :)
