It is asking to find the cost (c) for (p) number of pizzas at $8 each. So 1 pizza would be $8 and 2 would be 2 * 8 = 16 and 3 would be 3 * 8 = 24 and 4 would be 4 * 8 = 32 and p would be p * 8 = c. So the answer is:
c = 8p
15. a ratio is a fraction comparing numbers showing how they relate to each other.
if she mixed 3 ounces of blue and 2 of yellow, this would make 5 ounces of green paint. So the ratio is 3/2. to get 20 ounces of green paint she would have to do this mixture 4 times since she gets five each time. If she mixes 2 ounces of yellow paint four times, she would use 4 * 2 = 8 ounces of yellow painy
Answer:
a
Step-by-step explanation:
Discriminant = b^2 - 4ac; where a = 1, b = 9 and c = 14
d = (9)^2 - 4(1)(14)
d = 81 - 56
d = 25
the discriminant is greater than zero, so there are two real roots
Answer:
The correct option is (B)
.
Step-by-step explanation:
The exponential decay function is as follows:

Here,
<em>y = </em>final value
<em>a</em> = initial value
<em>r</em> = decay rate
<em>t</em> = time taken
It is provided that:
<em>a = </em>150 mg
<em>r</em> = 9% = 0.09
Then the next hour the amount of caffeine in the body will be:

Then after two hours the amount of caffeine in the body will be:

Similarly after 10 hours the amount of caffeine in the body will be:

Then the inequality representing the range of the exponential function that models this situation is:

Thus, the correct option is (B).
