Answer:

y(x) = 9 + 0.25*(18 - x)

Step-by-step explanation:

We have the following variables:

y: hours of sleep

x: age

Each day, a young person should sleep 9 hours

This means that y is 9 added to something

plus 1 4 hour for each year that the person is under 18 years of age.

For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.

So the equation relating hours of sleep y and age x is:

y(x) = 9 + 0.25*(18 - x)

Anuta_ua [19.1K]

first you would put the expression in a fraction for

180/460

you already know that the both numbers are divisible by 2

  • so the answer would be 90/230 but we are still no done because these values are divisible by three

the rule to prove that the number is divisible by three is when you add the digits of the number for example 333. 3+3+3=9 and nine is divisible by nine

THE ANSWER IS:::::::: 90/230

A circle has an area of 4040 square meters. Which answer is closest to the measure of its diameter?
ch4aika [34]
Well the answer I got was closest to 71.

3.14 x radius squared = area

If you divide 4040 by 3.14 you get radius squared which is 1286.6242
If you square root it you get the radius which is 35.869544
If you multiply the radius by 2 you get diameter which is about 71.739088

Use the method from the Example to approximate the solution to the equations below to two decimal places.
STALIN [3.7K]

Answer:

x = 3.85

Step-by-step explanation:

Given equation:

6ˣ = 1,000

now,

on taking log both sides, we get

⇒ log(6ˣ) = log(1,000)

or

⇒ log(6ˣ) = log(10³)

now we know the property of log function that

log(aᵇ) = b × log(a)

thus, applying the above property, we get

⇒ x × log(6) = 3log(10)

or

⇒ x × log(2×3) = 3log(10)

now,

we have another property of log function as":

log(A) = log(A) + log(B)

therefore,

x × [log(2) + log(3)] = 3log(10)

also,

log(10) = 1

log(2) = 0.3010

log(3) = 0.4771

Thus,

⇒ x × [0.3010 + 0.4771 ] = 3 × 1

or

⇒ x × 0.7781 = 3

or

⇒ x = 3.85
