If 8 apples cost $ 4, then (4/8) = 1/2 (or 0.50)....so each apple is 0.50 (or 50 cents)
so if u want 9 apples, u will have to pay : 9 * 0.50 = $ 4.50 <=
The slopes of perpendicular lines are negative reciprocals.
If one line has a slope of 1/6, then the negative reciprocal would be -6/1 which is simplifies as -6.
The answer is C.
Answer: It will take about 77 years (76.8 years).
Step-by-step explanation: Time is given by the equation: N=No.e^kt. You know that the concentration has to be 15% from the original so N=15 and No=100. To determine k, you have to look at the half-life. k=ln(0.5)/half-life time. For 28 years, k=-0.0247. Replacing it back into the N=No.e^kt equation, the answer will be 76.8 years.
Answer:
The answer to your question is: 4a² + 4b² + 8ab
Step-by-step explanation:
Simplify 4(a² + b² + 2ab)
The only step is to multiply 4 by each term
4a² + 4b² + 8ab
30% of 500 days is 150.
You'll change your percent into a decimal that will leave you with 0.30.
Next, multiply 0.30 by 500.
Your answer will show 150.
