Answer:
* 100
Step-by-step explanation:
The voters would be 11+15 and since there were 11 votes for A, that is the equation you should use.
Answer:
306 km
Step-by-step explanation:
put both of them to equal in ratio form so now
85 / (7/6) = x / (21/5)
85 * (21/5) = 7/6x
357 = 7/6x
x = 306 km
Answer:
D) 32.6
Step-by-step explanation:
This question is asked to find the value of "c", a variable.
We can rewrite the equation like this: 62 = 29.4 + c.
So, something + 29.4 = 62.
62 - 29.4 = 32.6.
Hope this helps!
Answer:
x=2, y=3
Step-by-step explanation:
Answer:
18.75 mg
Step-by-step explanation:
We can model this problem using the exponencial equation:
y = yo * (1 + r)^x
Where y is the final value, yo is the inicial value, r is the rate and x is the amount of time.
In this problem, we want to find y after x = 4 hours (from 9am to 1pm), we have yo = 300 and r = -0.5 (for every hour, half the caffeine leaves the body). So we have that:
y = 300 * (1 - 0.5)^4
y = 300 * 0.5^4
y = 300 * 0.0625
y = 18.75 mg
