Answer:
66.5 liters
Step-by-step explanation:
0.95 x 70 is 66.5
Answer:
10.47 s
Step-by-step explanation:
We must solve the quadratic equations for t.
1. On the moon
h = -0.8t² + 10t +2
The standard form of a quadratic equation is
y = ax² + bx + c = 0
By comparing like terms, we see that
a = -0.8; b = 10; c = 2
We can now use the quadratic formula:
(a) Evaluate the discriminant D
D = b² - 4ac = 10² - 4 × (-0.8) × 2 = 100 + 6.4 = 106.4
(b) Solve for x
2. On the Earth
(a) Evaluate the discriminant
D = b² - 4ac = 10² - 4 × (-4.9) × 2 = 100 + 39.2 = 139.2
(b) Solve for x
3. Difference in time of flight
Time on Moon - time on Earth = 12.70 s - 2.22 s = 10.47 s
The ball will stay in flight 10.47 s longer on the moon than on Earth.
The graphs below show the times of flight on the Moon and on Earth
P = 2(L + W)
84 = 2(35 + W)
84/2 = 35 + W
42 = 35 + W
W = 42 - 35
W = 7

Answer
Equation Simplified = 35 +0.05 x 35 = 36.75
Step by step
5% = 0.05
35 in this equation represents the principle
0.05 represents the rate
35 + 0.05 x 35 = 36.75
Simplified Equation: 35 +0.05 x 35
Price After Markup = 36.75
