A meteorologist monitors the steady snowfall for a report on the news. After 2 hours, there are 10 inches of snow on the ground. There are 12 inches of snow 2 hours later. Write a linear function rule for y, the depth of the snow on the ground, after any number of hours x. If the meteorologist started measuring the snow at noon, how deep will the snow be when the news airs at 6 P.M?

Answers

Answer:

14 inches

Step-by-step explanation:

x = number of hours

y = depth of the snow on the ground

Formula:

y = ax + b

Informations: when the monitors started, there are a quantity of inches on the ground. 2 hours later, there are 10 inches. Then:

10 = 2a + b

2 hours later, there are 12 inches:

4a + b = 12

a and b, in both equations, are the same value. Then:

{2a + b = 10

{4a + b = 12

{- 2a - b = - 10

{4a + b = 12

---------------------

2a = 2

a = 1

2a + b = 10

2.1 + b = 10

2 + b = 10

b = 10 - 2

b = 8

Then, the linear function rule is:

y = x + 8

At noon, x = 0.

At 6 P.M, x = 6

Changing x for 6 in linear function rule:

y = 6 + 8

y = 14

Yellow cab taxi charges $3.00 flat rate and $0.65 per mile. If Katie has no more than $10 to spend. How many miles can she travel without exceeding her limit?

Answers

Answer:

0.65+0.65=1.30+0.65=1.95+0.65=2.60

Step-by-step explanation:

well katie if katie wants to spend 3.00 she would have to do add it 4 times and it will be 2.60 and she would save 0.40 cents but if she adds it again it would be 3.25.

Write a power represented with a positive base and a positive exponent whose value is less than the base.

Answers

For this case we must write a number of the form:

Where,

a: power base

b: exponent of the power

We must write a power that complies with the following inequality:

Substituting values we have, for example:

What the circumference of the base?

Answers

The formula for the circumference of a circle is:

C = 2πr

The radius (r) is half of the diameter, so to find the radius just divide the diameter by two...

radius = 20 ÷ 2

radius (r) = 10 m

Plug in what you know into the formula for the circumference:

C = 2π(10)

C = 20π

The exact circumference is: 20π m

The approximate circumference is: 63 m

Hope this helped!
