How do you use scientific notation to estimate the hours in a year

Answer:

8.760 x 10^3

Step-by-step explanation:

There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.

Hope this helps! :)

UkoKoshka [18]

Answer:

$f(x) = 1500x +3000$

Step-by-step explanation:

Given

Represent the months with x and the earnings with y.

So:

$(x_1,y_1) = (1,4500)$

$(x_2,y_2) = (2,6000)$

Required

Determine the linear function

First, calculate slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{6000 - 4500}{2 - 1}$

$m = \frac{1500}{1}$

$m = 1500$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

$y = 1500(x - 1) + 4500$

$y = 1500x - 1500 + 4500$

$y = 1500x +3000$

As a function, we have:

$f(x) = 1500x +3000$

Carmen's golf score is 6 strokes less than Linda's. Their two scores total 156. What is each girls score?

DochEvi [55]

Answer:

Carmen's score is 75 strokes.

Linda's score is 81 strokes.

Step-by-step explanation:

Let the score of Linda be "x".

<em>It is given that Carmen's golf score is 6 strokes less than Linda's.</em>

Thus, Carmen's score is (x-6).

The total score of the girls is

= $x + (x-6) = 2x-6$

The total score is given to be 156.

Thus, the equation becomes,

$2x-6 = 156$

$2x= 162$

$x = 81$

<em>Thus Linda's score is 81 and Carmen's score is (156-81) 75.</em>
