A weather balloon is descending from the atmosphere. Its altitude changes by
OlgaM077 [116]

The change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

Given that a weather balloon is descending from the atmosphere, and its altitude changes by -6 meters every second, to determine what is the change in altitude after 135 seconds the following calculation must be performed:

  • Amount of time x change per second = total change
  • 135 x (-6) = X
  • -810 = X

Thus, the change in altitude after 135 seconds was a decrease of 810 meters, that is, -810 meters.

What is an equation of the line that passes through the point (1,-3) and is perpendicular to the line x+3y=21
docker41 [41]

The linear equation that is perpendicular to the line x+3y=21 is:

y = 3*x - 6

<h3>How to find the equation of the line?</h3>

A general line in the slope-intercept form is written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

Two linear equations are perpendicular if the product between the two slopes is equal to -1.

Rewriting the given line we can get:

x +3y = 21

3y = 21 - x

y = 21/3 - x/3

y = (-1/3)*x + 21/3

Then the slope is (-1/3), if our line is perpendicular to this one, then:

m*(-1/3) = -1

m = 3

our line is:

y = 3*x + b

To find the value of b, we use the fact that our line passes through (1, - 3)

-3 = 3*1 + b

-3 - 3 = b

-6 = b

The line is y = 3*x - 6

The states C and D spend a total of ​$54.6 million for tourism. The state C spends ​$2 million more than the state D. Find the a
Roman55 [17]

State C spent $28.3 million and State D spent $26.3 million.

Step-by-step explanation:

Total spent for tourism = $54.6 million

Let,

The amount spent by State C = x

The amount spent by State D = y

According to given statement;

x+y = 54.6    Eqn 1

x=y+2    Eqn 2

Putting value of x from Eqn 2 in Eqn 1

(y+2)+y-54.6\\y+2+y=54.6\\2y=54.6-2\\2y=52.6\\

Dividing both sides by 2

\frac{2y}{2}=\frac{52.6}{2}\\y=26.3

Putting y=26.3 in Eqn 2

x=26.3+2\\x=28.3\\

State C spent $28.3 million and State D spent $26.3 million.
