Answer: I don't know about the formula, but consider the logic below.

Step-by-step explanation:

Martina = 12

Joey = 0

12 x 3 = 36

36 - 3 = 33

If Joey was 21, Martina would be 33.

April shoots an arrow upward at a speed of 80 ft/sec from a platform of 25 ft. High. The pathway of the arrow can be represented
soldi70 [24.7K]

Answer:

125feet

Step-by-step explanation:

Given the equation that modeled the height expressed as h = -16t^2 + 80t + 25, where h is the height and t is the time in seconds.

The arrow reaches the maximum height at dh/dt = 0

dh/dt = -32t + 80

0= -32t+80

32t = 80

t = 80/32

t = 2.5secs

substitute t = 2.5 into the formula;

h = -16t^2 + 80t + 25

h = -16(2.5)^2 + 80(2.5) + 25

h = -16(6.25)+225

h = -100+225

h = 125

Hence the maximum height the arrow reaches is 125feet

The answer of the question,, it's a maths questions
olga55 [171]
You can solve this problem two ways.

1. Divide 68g by 100 to get how many grams per pound and multiply that by 150. This is the hard way.

2. Multiply 68 by 1.5 to get your answer. This is possible because 150 is 1.5 of 100, so multiplying the amount for 100 by 1.5 gives you your answer.
