Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year ago?

Answers

Answer:

weight of the kitten last year = 9 ounces

Step-by-step explanation:

Let

x = weight of the kitten last year

Weight of the kitten this year = 2 1/3 * x = 21

7/3*x = 21

7/3x = 21

x = 21 ÷ 7/3

x = 21 × 3/7

= 63/7

x = 9 ounces

weight of the kitten last year = 9 ounces

Answers

Answer:

In 2020 the population would be 673.

Step-by-step explanation:

Giving the following information:

Current population (PV)= 250

Growth rate (g)= 2% annualy

Number of periods (n)= 2020 - 1970= 50 years

To calculate the number of people in 2020, we need to use the following formula:

FV= PV*(1+g)^n

FV= 250*(1.02^50)

FV= 672.89 = 673

What is the equation of the line that passes through the point (8, 4) and has a slope
of 3/2?

Answers

Answer:

y = (3/2)x - 8    slope-intercept form

3x - 2y = 16      standard form

Step-by-step explanation:

Use the point-slope form of a line to do this problem.

[tex]y - y_{1} = m(x - x_{1} )\\[/tex]

In your case [tex](x_{1} , y_{1} ) = (8, 4)[/tex]

So. y - 4 = 3/2 ( x - 8)  

multiply thru by 2

2y - 8 = 3(x - 8)

2y - 8 = 3x - 24

2y = 3x - 16

y = (3/2)x - 8    slope-intercept form

3x - 2y = 16      standard form
