Hey! Sorry about your misunderstanding of your work, Allow me to help :)

Let's turn that phrase into an equation.

Negative K ( - k) over five ( /<span>5 ) equals ( = )  seven (7) over five ( /5)

Let's put that together.

- k/5 = 7/5

To solve, we need to get rid of the fraction by getting rid of the denominator, in this case, the denominator for both sides is 5. Multiply each side by 5 to cancel out the 5. We get :

- k = 7

Now we need to get rid of that negative sign next to k, so what we do is divide each side by -1 so we can cancel out that negative 1 next to k.

Our Final answer is k = -7 .

To measure the height of the cloud cover at an airport, a worker shines a spotlight upward at an angle 75° from the horizontal.
DaniilM [7]
The geometry of the problem does not seem well-described here. Assuming the spotlight beam and the observation are in the same vertical plane, there are two possibilities for the height:
.. 446 m . . . . . spotlight is aimed toward observer
.. 772 m . . . . . spotlight is aimed away from observer

See the attachment for the geometry. Choose the answer corresponding to the geometry of the problem.

The amount of sales tax varies directly with the cost of the purchase. If the sales tax is $3.80 on a purchase of $76 what would
polet [3.4K]

Answer:

The sales tax is equal to \$2.3

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

y-----> the cost of the purchase

x ----> the sales tax

step 1

Find the value of k

For y=76, x=3.80

substitute

k=y/x

k=76/3.8

k=20

The linear equation is equal to

y=20x

step 2

what would be the sales tax on a purchase of $46

For y=46, x=?

substitute in the equation

46=20x

x=46/20

x=\$2.3
