Answer:

We can write sin 21° as 1200 / x and also 0.36 so we can write:

1200 / x = 0.36

1200 = 0.36x

x = 1200 / 0.36

x ≈ 3333 ft

Answer:

x = 12

Step-by-step explanation:

The sum of the two smaller angles is 140

80+5x = 140

Subtract 80 from each side

80+5x-80 =140-80

5x = 60

Divide each side by 5

The amount Lin's sister earns at her part-time job is proportional to the number
gulaghasi [49]

Answer:

y = 9.6x

Yes, y is a function of x.

x =  \frac{5}{48} y

Step-by-step explanation:

For a proportional relation, the equation is given by:

y = kx

where k is the unit rate of change.

We were told that, Lin's sister earns $9.6 per hour.

This means k=9.6.

We substitute to get:

y = 9.6x

We could rewrite this as

y(x) = 9.6x

Yes, y is a function of x.

To obtain an equation describing x as a function of y, we solve for x to get:

x =  \frac{1}{9.6} y
