1+1/3+1/3 because 1/3 and 1/3 have the same denominator.
Answer:
B
Step-by-step explanation:
In a parellelogram opposite angles are always equal
In 3's multiplication table every next number is addition of 3 to its previous number.
The 3' s multiplication table is,
3, 3+3=6, 6+3=9, 9+3=12, 12+3=15, 15+3=18,.... so on.
I’m not quite sure but I think it’s B)
Answer:
Step-by-step explanation:
Pythagorean theorem: base ² +altitude² = hypotenuse²
1) hypotenuse² = base² + altitude²
x² = 6² + 3²
= 36 + 9
= 45
x = √45
x = 6.7 cm
4) base ² +altitude² = hypotenuse²
x ² + 3.7 ² = 4.2 ²
x ² + 13.69 = 17.64
x ² = 17.64 - 13.69 = 3.95
x = √3.95
x = 1.99 cm
10)c ² = a ² + b ²
= 3 ² +4 ²
= 9 + 16
c ² = 25
c = √25 = 5
11) a ² + b ² = c ²
9 ² +b² = 13 ²
81 + b² = 169
b² = 169 - 81 = 88
b = 9.38
12) a² + b² = c²
12² + b² = 22²
144 + b² = 484
b² = 484 - 144 = 340
b =√340 = 18.44
