Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number
Answer: I think its A
Step-by-step explanation:
Answer:
The answer is the first choice, x < −4.
Step-by-step explanation:
Let's solve your inequality step-by-step.
2x−2>4x+6
Step 1: Subtract 4x from both sides.
2x−2−4x>4x+6−4x
−2x−2>6
Step 2: Add 2 to both sides.
−2x−2+2>6+2
−2x>8
Step 3: Divide both sides by -2.
x<−4
10 minutes warm-up, 25 minutes lifting weights, 15 minutes treadmill.....so the entire workout is (10 + 25 + 15) = 50 minutes
the ratio of minutes lifting weights to total workout...
he lifted weights 25 minutes
the total workout was 50 minutes
so the ratio is : 25/50 which reduces to 1/2 or 1:2 or 1 to 2 <==
Answer: the answer is 15000.
