Answer:
2) 92.2km
3) B
4) 4.8m
Step-by-step explanation:
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
Answer:
for #1: 70x = y
for #2: 70x + 100 = y
Step-by-step explanation:
you pay $70 for x amount of time with will equal your total therefore it's 70x = y
if you have to pay a one-time fee of $100.00 then you have to add that to your equation giving you 70x + 100 = y
hope this is right
hope it helps too :)
There are 5 x 10 = 50 different outcomes.
Of them only 3x10, 4x10, 4x9, 4x8, 5x10, 5x9, 5x8, 5x7 and 5x6 are greater or equal than 30. Those are 9 possibilities.
Then 50 - 9 = 41 are the possibilities that the product of the two numbers is less than 30.
The probalility, then, is 41/50 = 0.82
