Two numbers such that the greater number is 75 percent more than the lesser number

victus00 [196]

<h2>Greetings!</h2>

If x = the first number (equal to 1x) then the second number is 75% more than this.

This means the value of the bigger number is 100 + 75 (because 100 is the starting number and 75 is the percent bigger)

This can be shown with the following equation:

Amount * $\frac{percentage}{100}$

x * $\frac{175}{100}$ = 1.75x

1.75x is the value of the bigger number.

<h2>Hope this helps!</h2>

The salary at Beth’s company is $32,000 for someone with no experience and increases by $2700 per year of experience. Write a ru

AlekseyPX

Answer:

In general, the salary S in terms of years of experience Y is S = 2700Y + 3200

Step-by-step explanation:

we start at 32000 without experience.

as the experience goes up, the wage increases 2700 per year so we can multiply 2700 by the years of experience to find the increase of salary. To find the salary of a certain employee with a certain amount of experience, plug the years of experience in for Y and solve.

for Y=0

S= 2700(0) + 3200 = 0 + 3200 = 0

for Y=2

S= 2700(2) + 3200 = 5400 + 3200 = 8600

for Y=5

S= 2700(5) + 3200 = 13500 + 3200 = 16700

for Y=7

S=2700(7) + 3200 = 2700(5) + 2700(2) + 3200 = 5400 + 13500 + 3200 = 22100

Please Help me! Algebra 1

Option a: The number of bacteria at time x is 0.

Option b: An exponential function that represents the population is $y=200(1.5)^x$

Option c: The population after 10 minutes is 11534(app)

Explanation:

It is given that the coordinates of the graph are (0,200), (1,300) and (2, 450)

Option a: To determine the number of bacteria x when y = 200

From the graph, we can see that the line meets y = 200 when x = 0

Thus, the coordinates are (0,200)

Hence, the number of bacteria at time x is 0 when y = 200.

Option b: Now, we shall determine the exponential function of the population.

The general formula for exponential function is $y=a \cdot b^{x}$

Where a is the starting point and $a=200$

b is the common difference.

To determine the common difference, let us divide,

$\frac{300}{200} =1.5$

Also, $\frac{450}{300} =1.5$

Hence, the common difference is $b=1.5$

Thus, substituting the values $a=200$ and $b=1.5$ in the formula $y=a \cdot b^{x}$ ,

we have, $y=200(1.5)^x$

Hence, An exponential function that represents the population is $y=200(1.5)^x$

Option c: To determine the population after 10 minutes, let us substitute $x=10$ in $y=200(1.5)^x$ , since the x represents the population of the bacteria in minutes.

Thus, we have,

$\begin{aligned}y &=200(1.5)^{x} \\&=200(1.5)^{10} \\&=200(57.67) \\&=11534\end{aligned}$

Hence, the population after 10 minutes is 11534(app)
