The equation, y = 1250x + 22,850, gives the salary of a person as "y" after the stated number of years (x). Model the data with

Sidana [21]

Answer:

(a) $y = 6250x +17850$ --- The function

(b) $y = 49100$ --- The salary in 5 years

Step-by-step explanation:

Given

$y = 1250x + 22850$

Solving (a): Model the function around (1,24100) and (3,36600)

First, we calculate the slope

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

$m = \frac{36600 - 24100}{3 - 1}$

$m = \frac{12500}{2}$

$m = 6250$

The function is then calculated as:

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

$y = 6250(x - 1) + 24100$

$y = 6250x - 6250 + 24100$

$y = 6250x +17850$

Solving (b): Salary in 5 years

Here:

$x = 5$

So:

$y = 6250x +17850$

$y = 6250*5 +17850$

$y = 49100$

It takes Hayden 1 1/2 minutes t complete each level of his video game. If he plays for 10 1/4 minutes, how many levels will he c

antoniya [11.8K]

Given:

Hayden $1\dfrac{1}{2}$ minutes to complete each level of his video game.

He plays for $10\dfrac{1}{4}$ minutes.

To find:

The number of levels he will complete.

Solution:

We have,

Required time for each level = $1\dfrac{1}{2}$

Total time = $10\dfrac{1}{4}$

The number of level is

$n=\dfrac{\text{Total time}}{\text{Required time for each level}}$

$n=\dfrac{10\dfrac{1}{4}}{1\dfrac{1}{2}}$

$n=\dfrac{\dfrac{10(4)+1}{4}}{\dfrac{1(2)+1}{2}}$

$n=\dfrac{\dfrac{41}{4}}{\dfrac{3}{2}}$

On further simplification, we get

$n=\dfrac{41}{4}\times \dfrac{2}{3}$

$n=\dfrac{41}{6}$

$n=6.8333...$

Number of levels must be a whole number. So, approx to value to the preceding whole number.

$n\approx 6$

Therefore, Hayden will complete 6 levels if he plays for $10\dfrac{1}{4}$ minutes.

Debra has 2/3 of a pound of loose green tea leaves. If she wants to keep one-half if the tea at home and the other half at work,

stealth61 [152]

The answer is 1/6 because 2/3-1/2 the command denominator is 6 so 2 goes in six 3 times then you do 3×1 =3 so you got 3/6 then you do 3 goes in 6 2 times then you do 2×2=4 and 4-3=1 so you get 1/6
