Nesterboy [21]

Answer: 49.7^{\circ}F

Step-by-step explanation:

Given

The temperature on the ground is 56.9^{\circ}F

temperature drop observed is 1.2^{\circ}F\ \text{per 1000 ft}

The height of the plane is  6000\ ft

The total increase in height per 1000\ ft is 6 units

Temperature drop is

\Rightarrow 1.2\times 6=7.2^{\circ}F

The temperature at that altitude is

\Rightarrow 56.9-7.2=49.7^{\circ}F

Harper wants to exchange £350 for dollars, how many more dollars would she get in the bank than in the post office
musickatia [10]

Answer: $24.50

Post office:£1 = $1.27

£350 = $1.27 × 350 = $444.50

Bank:£1 = $1.34

£350 = $1.34 × 350 = $469

Therefore, the difference will be:

= $469 - $444.50

= $24.50

Need to find A and B, I already found C
Semenov [28]
I'm going to assume you've learn sin, cos, and tan. To find a you must do:
sin^{ - 1}  =  \frac{a}{12}
Once you find a, you can use the Pythagorean Theorem to find b:
{a}^{2}  +  {b}^{2}  =  {c}^{2}
Or you can do:
cos^{ - 1}  =  \frac{b}{12}
You can find these functions on a scientific calculator. Let me now if you need more help.
