Answer:
3 tenths
Step-by-step explanation:
One candy bar
= 1 candy bar
= 1.0, or 10 tenths (one tenth is 0.1)
If Theo eats 0.7 of a candy bar, we know that
1.0 - 0.7 = 0.3
0.3 = 3 *0.1 (one tenth)
Therefore, the answer is 3 tenths.

3+7=10
55/10=5.5
5.5 x 3=16.5
5.5 x 7=38.5
16.5 : 38.5
Using SOH CAH TOA
Sin =opposite/hypotenuse
that means opposite=2
Hypotenuse=3
Cos=Adjacent/Hypotenuse
Using Pythagorean theorem
Hyp^2=Opp^2 +Adj^2
3^2 =2^2+adj^2
9=4+adj^2
9-4=adj^2
5=adj^2
Taking the square root of both sides
√5=adj
:: cos=√5/3
