Answer:
116*
Step-by-step explanation:
36* + 28* = 64*
180* - 64* = 116*
The height when the ball drops would be 0, so plug in 0 for h(t):
0 = -16t^2 + 500
Then you would solve for t, which in this case would equal to the time it takes to land.
-500 = -16t^2
t = 5.59, so it would take about 5.6 seconds to reach the ground.
Answer:
full page = 8
half page = 5
Step-by-step explanation:
two equations can be derived from the question
40x + 75y = 800 equation 1
x + y = 13 equation 2
x = number of half page advertisement
y = number of full page advertisement
multiply equation 2 by 40
40x + 40y = 520 equation 3
subtract equation 3 from 2
280 = 35y
y = 8
substitute for y in equation 2
x + 8 = 13
x = 13 - 8
x = 5
Answer:
x = 57
Step-by-step explanation:
XZ divides <WXY into two equal parts. Which implies that:
m<ZXY = m<ZXW
Therefore:
m<WXY = 2(m<ZXY)
m<ZXY = 58°
m<WXY = 2x + 2
Plug in the values into the equation
2x + 2 = 2(58)
2x + 2 = 116
2x = 116 - 2 (subtraction property of equality)
2x = 114
x = 114/2 (division property of equality)
x = 57
