Answer:

\text{sin}(43.4^{\circ})\approx 0.68708751

Step-by-step explanation:

We are asked to evaluate the given trigonometric expression \text{sin}(43^{\circ}24').

We can see that our given angle is in degrees and minutes, so we will convert measure of minutes into degrees by dividing 24 by 60 as:

\frac{24}{60}=0.4^{\circ}

Now, we will find the value of our given expression.

\text{sin}(43.4^{\circ})=0.687087510804

Round to eight decimal places:

\text{sin}(43.4^{\circ})\approx 0.68708751

Therefore, the value of the given expression would be 0.68708751.

Julie works in chicago and has to pay $14 per day on tolls and $76 a day for gas. If she makes $19 an hour how many hours must s
enot [183]

Answer:

19 hours.

Step-by-step explanation:

T = -14 -76 + 19h

The -14 is the cost for tolls, and the -76 is the cost for gas. The 19h is the amount she'll get per hour if she makes $19/hour. And T is the total profit

We want to solve for h if T = 260

260 = -14 -76 + 19h

+14      +14

274 = -76 +19h

+76    +76

350 = 19h

/19      /19

18.42 = h

She must work 19 hours.

Hope this helps!
