Answer:
see below
Step-by-step explanation:
Monica earned twice as much as Samuel
m = 2*s
Divide each side by 2
1/2 m = 1/2 ( 2s)
1/2 m = s
If monica earned 56
1/2 (56) = s
28 =s
This is the required formula.
2) 92.2km
3) B
4) 4.8m
Equation: a² + b² = c²
2)
60² + 70² = c²
3600 + 4900 = c²
8500 = c²
√8500 = c
92.2 = c
3)
12² + 4² = c²
144 + 16 = c²
160 = c²
√160 = c
12.6 = c
4)
4.5² + 1.6² = c²
20.25 + 2.56 = c²
22.81 = c²
√22.81 = c
4.8 = c
