The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. What is the temperature outside a plane flying at an altitude of 5 kilometers?

Answers

Answer 1

Answer:

Answer:

$-22$ degrees Celsius.

Step-by-step explanation:

Let x represent number of kilometers.

We have been given that the temperature decreases by 6.8 degrees Celsius for every increase of 1 kilometer above the ground. So temperature decreased in x hours would be $-6.8x$ .

The ground temperature at Brigham Airport is 12 degrees Celsius. The temperature at an altitude of x kilometers would be $12-6.8x$ .

To find temperature outside a plane flying at an altitude of 5 kilometers, we will substitute $x=5$ in our expression as:

$12-6.8(5)$

$12-34$

$-22$

Therefore, the temperature outside a plane flying at an altitude of 5 kilometers would be $-22$ degrees Celsius.

Answer 2

Answer: -22 degrees Celsius should be the answer
6.8 times 5 is 34
since 34 is bigger than 12, you take 12 from 34 and add a negative sign, and that would be -22.
You can use a calculator if u want and is allowed too. :)

Is the square root of 130 rational or irrational? and where would it be located on a number line?

Answers

Let's start by the easiest question, the second.

We knoa that $11^2=121\ \textless \ 130\ \textless \ 12^2=144$ hence $\boxed{11\ \textless \ √(130)\ \textless \ 12}$

Now let's try simplifying the square root of $130$ : $130=2\cdot5\cdot13$ , which are all prime numbers that appear only once : the square root of 130 is irrational.

while shopping,lucinda spent $48. if the amount she spent was 15% of her savings, how much savings did she have before shopping?

Answers

15% is the same as $(15)/(100)$
We can simplify this fraction by dividing by 5 from both the numerator and the denominator.
$(15)/(100)$ ÷ $(5)/(5)$ = $(3)/(20)$
Now we know that part of the money Lucinda spent is 15%.
Since it wasn't her total money and only part of it, 48 will be the numerator.
We are trying to find the total amount of savings (her total money)
Now we can create a proportion.
$(48)/(x) = (3)/(20)$
48 ÷ 3 = 16
Now multiply the numerator and denominator by 16 :)
$(3)/(20)$ × $(16)/(16)$ = $(48)/(320)$
And yes the answer is 320 since that was the total amount of money spent
