Choose the equation you would use to find the altitude of the airplane. tan70 = 0 tan70 = sin70 =
KonstantinChe [14]
The situation is represented by a drawing with a right triangle where an airplane is at the top corner, the elevation angle (opposite to the airplane) is 70°, the height (vertical leg) is x, and the adjacent leg (horizontal leg) to the 70° angle is 800.

Then, to find the height x, which is the opposite leg to the angle,  you can use the tangent ratio, which is opposite leg divided by adjacent leg:

tan(x) = opposite leg / adjacent leg => tan(70°) = x / 800

Answer: tan(70°) = x / 800

Dan earns £9.30 per hour. How much will he earn for 9 hours work?
Dimas [21]

Answer: £83.70

Step-by-step explanation:

We can set up a ratio.

Let x be the amount he earns for 9 hours of work.

\frac{9.30 pounds}{1 hour} = \frac{x pounds}{9 hours}

We can cross multiply:

x = 9*9.3

x = £83.70

Gavin took a taxi home from the airport. The taxi fare was $7 plus an additional $0.65 per mile.
Alexeev081 [22]

Answer:

a)

We know that:

There is a fixed cost of $7

for each mile, you need to pay $0.65

Then if you take the taxi for "m" miles, the total cost is:

c(m) = $0.65*m + $7

Now we know that Gavin also gives a $3 tip, so we need to add this to the cost:

c(m) = ($0.65*m + $7) + $3 = $0.65*m + $10

c(m) = $0.65*m + $10

Now we know that he paid a total of $62.65

Then:

c(m) = $62.65 =  $0.65*m + $10

This is the equation we need to solve in order to find m, the number of miles between Gavin's house and the airport.

b)

$62.65 =  $0.65*m + $10

We only need to isolate m, we will get:

$62.65 - $10 =   $0.65*m

$52.65/$0.65 =  m = 81

This means that there are 81 miles between the airport and Gavin's house.
