Answers

Answer 1

Answer: so 9:30 17 min goes by so its 9:47 but tim arrived 8 mins before so it was 9:39 when he arrived. Next tyson arrived 20 min after tims ORIGINAL oppt 9:47 20 min 10:07 then for marks 35 min after witch is 10:12

Three times twice an unknown number equals 30.

Answers

If three times twice an unknown number equals 30, then the unknown number is 5.

What is the unknown number in the question ?

It is given that three times twice an unknown number equals 30.

Let the unknown number be x.

From the above information,

⇒ 3*(2x) = 30

⇒ 6x = 30

∴ x = 5

Thus the unknown number is 5 .

Therefore, if three times twice an unknown number equals 30, then the unknown number is 5.

x is unknown number
3x=30
divide by three on both sides and get
x=10

A 2000 gram sample of radioactivematter will completely decay (be
undetectable) in 20 hours. There
exists a set of ordered pairs (t, m),
where t is the amount of time in hours
that the substance has been decaying,
and m is the mass in grams that has
decayed.
If t > 0, what is the range of m?

Answers

Answer:

The range is 0 < m < 2000 when t > 0

Step-by-step explanation:

* Lets explain how to solve the problem

- The exponential function is $f(x)= a(b)^(x)$ , where

a is the initial amount and b is the growth factor

- If b > 1, then it is exponential growth function

- If 0 < b < 1, then it is exponential decay function

* Lets solve the problem

- A 2000 gram sample of radioactive matter will completely decay

(be undetectable) in 20 hours

- There is a set of ordered pairs (t , m) exists, where t is the amount

of time in hours that the substance has been decaying and m is

the mass in grams that has decayed

∵ We can represent this situation by an exponential decay function

∴ $m(t)= 2000(b)^(t)$ , where b is the growth factor which is

greater than zero and less than 1 , t is the lime in hours and

m(t) is the mass of the substance in gram

- In any function the domain is the value of x and the range is

the value of y

∵ In the function the domain is t and the range is m

∵ When t = 0 then m = 2000 ⇒ initial amount

∵ When t = 20 then m will be closed to zero

∴ The domain of the function is 0 < t < 20

∴ The range of the function is 0 < m < 2000

* The range is 0 < m < 2000 when t > 0

Your hot air balloon is rising at the rate of 4 feet per second. Another aircraft nearby is at 7452 feet and is losing altitude at the rate of 30 feet per second. In how many seconds will your hot air balloon be at the same altitude as the other aircraft?

Answers

Answer:

$219.2\ sec$

Step-by-step explanation:

Let

y ----> the altitude in feet

x ----> the time in seconds

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope ot unit rate

b is the y-intercept or initial value

In this problem we have

Your hot air balloon

The slope is equal to $m=4\ (ft)/(sec)$

The y-intercept is $b=0$ ---> represent a proportional relationship

The linear equation is

$y=4x$ ----> equation B

Another aircraft

The slope is equal to $m=-30\ (ft)/(sec)$ ---> is negative because is a decreasing function

The y-intercept is $b=7,452\ ft$

The linear equation is

$y=-30x+7,452$ ----> equation B

Equate equation A and equation B

$4x=-30x+7,452$

solve for x

Adds 30x both sides

$4x+30x=7,452$

$34x=7,452$

Divide by 34 both sides

$x=219.2\ sec$
