Equation:
Time*speed= distance
1.7(time)*22.4(speed)=38.08meter(distance)
Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.
Answer:
130 quarters, 9 candies
Step-by-step explanation:
Answer:
11 seconds
Step-by-step explanation:
If the height h(t) of the sunglasses after t seconds is given by the polynomial function
h(t)=-16t²+1936
The sunglasses will hit the ground when the height h(t)=0
h(t)=-16t²+1936=0
-16t²+1936=0
-16t²=-1936
t²=1936/16=121
t=√121=11 seconds
The Sunglasses will hit the ground 11 seconds after it is dropped by the pilot.
X= 180 - (55 + [180 - 105])
x = 180 - (55 + 75)
x = 180 - 130
x = 50
