Answer:
Speed of hike = 1.7 miles per hour
Step-by-step explanation:
Given:
Total distance = 8 miles
Distance already traveled = 4.6 miles
Total time remain to travel = 2 hour
Find:
Speed of hike
Computation:
Distance remain = Total distance - Distance already traveled
Distance remain = 8 miles - 4.6 miles
Distance remain = 3.4 miles
Speed of hike = Distance remain / Total time remain to travel
Speed of hike = 3.4 / 2
Speed of hike = 1.7 miles per hour
Answer and step-by-step explanation:
Tim Carter money made:
First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)
Because he works for 50 hours so next 10 hours (50-40) = 10 * (1.5*5.15)
= 10* 7.725 = $77.25
Total money he made:
= 206 + 77.25 = $283.25
Jeese Jones money amde:
First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)
Because he works for 47.5 hours so next 7.5 hours (47.5-40) = 7.5 * (1.5*5.15)
= 7.5 *7.725 = $57.9375
Total money Jeese Jones made:
= 206 + 57.9375 = $263.9375
Barbara Burns money made:
First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)
Because Barbara Burns works for 44 hours so next 4 hours (44-40) = 4 * (1.5*5.15)
= 4* 7.725 = $30.9
Total money Barbara Burns made:
= 206 + 30.9 = $236.9
Hope this help you :3
Answer:
s(t) = -4.9t² + 39.2t
Step-by-step explanation:
Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²
Given
g = -4.9m/s²
v0 = 39.2m/s
s0 = 0m (the initial height)
On substituting into the formula;
s(t) = gt² + v0t + s0
s(t) = -4.9t² + 39.2t + 0
s(t) = -4.9t² + 39.2t
This gives the equation that models the height
The answer is x=3
So c is 3
