Answer: 220
Step-by-step explanation: Use distributive propetry and PEMDAS to solve.
.06 x 13.46 =.80
.80 + 13.46 =14.46.
Answer: $14.46
Answer:
23.8
Step-by-step explanation:
2(5.7) + 2(6.2)
11.4 + 12.4
23.8

Step-by-step explanation:
but I'd love to help
To find the time at which both balls are at the same height, set the equations equal to each other then solve for t.
h = -16t^2 + 56t
h = -16t^2 + 156t - 248
-16t^2 + 56t = -16t^2 + 156t - 248
You can cancel out the -16t^2's to get
56t = 156t - 248
=> 0 = 100t - 248
=> 248 = 100t
=> 2.48 = t
Using this time value, plug into either equation to find the height.
h = 16(2.48)^2 + 56(2.48)
Final answer:
h = 40.4736
Hope I helped :)
