Answer:

g + 200 - 2*600 = 1400

g = 2400 pounds

Step-by-step explanation:

g + 200 - 2*600 = 1400

g + 200 - 1200 = 1400

g - 1000 = 1400

g = 2400

The function, f(t) = 100.000 describes the number of people who will become infected with a virus in t weeks. Approximately how
Alchen [17]

Answer:

100,000

Step-by-step explanation:

We are given a function: f(t) = 100,000, where,

f(t) is a function that tells us about the number of people who will be infected in t weeks. Here t that is number of week is the independent variable and f(t) is the dependent variable.

We observe that f(t) is a constant function that is it does not depend on the value of t. Whatever may be the value of t it will always take the constant value of 100,000.

So, after ten weeks that is we put t = 10, we get,

f(10) = 100,000

Thus, after 10 weeks 100,000 people will be infected.

A man walks 10 miles in x hours. How far does he walk in one hour?
Andreas93 [3]

Answer:

Option  (c) is correct.

The distance covered by the man in 1 hour is represented by te expression  \frac{10}{x} miles.

Step-by-step explanation:

Given: A man walks 10 miles in x hours.

We have to choose a correct  expression that represents the distance covered by the man in 1 hour.

Consider the given statement."A man walks 10 miles in x hours."

Using UNITARY METHOD,

(is a method in which we first find the value of a single unit and then multiply it with desired quantity)

Distance covered by man in x hours = 10 miles,

So distance covered by man in 1 hour = \frac{10}{x} miles.

So, The distance covered by the man in 1 hour is represented by te expression  \frac{10}{x} miles.

A certain bacteria is growing at a rate of 4 percent each day. If the culture of bacteria has 5,000 bacteria today, how many bac
Snezhnost [94]
This is the concept of exponential growth, To get the number of bacteria after 10 days we use the formula:
f(t)=ae^(kt)
where;
a=initial number=5000
k=constant of proportionality= 0.04
t=time=10 days
f(t)=future number
thus the number of bacteria in 10 days will be:
f(t)=5000e^(0.04*10)
f(t)=7,459.12
The answer is 7,459.12
