Two planes are the same altitude. From the airport , one plane is 50 km away in the direction of N°60 E and another is 80 km awa

Answer:

78.5 km

Step-by-step explanation:

Measured at the airport, the angle between the two planes is ...

180° -60° -50° = 70°

The law of cosines tells us the distance between the planes is ...

d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km

The planes are about 78.5 km apart.

If u subtract 17 from my number and multiply the difference by -7, the result is -35.What is my number

Kryger [21]

Let x = your number.

(x - 17) * -7 = -35. Divide each side by -7.

(x - 17) = 5. Add 17 to each side.

x = 22.

Your number is 22

Add and simplify 1/5 + 1/10

aliya0001 [1]

In order to add these fractions we have to make a common denominator.

1/5 can turn into 2/10 Its the same thing. And its easier to solve with.

now lets multiply.

$\frac{2}{10}$ × $\frac{1}{10}$

Now we add across

2 + 1 = 3

------------

10 + 10 = 10 ( When adding fractions like these the denominator stays the same)

So your answer is...

$\frac{3}{10}$

Good Luck! :)

Convert the following measurements. Round your answers to two decimal places. a. 14,974 pounds to tons b. 8,047 ounces to pounds

Vikki [24]

For this case we have to know the following conversions:
$1 ton = 2204.62 pounds

1 oz = 0.0625 pounds$
Now we apply the conversions:

14,974 pounds to tons:
$(14974) * (1 / 2204.62) = 6.79 tons
$

8,047 ounces to pounds:
$(8047) * (0.0625) = 502.94 pounds
$

64 ounces to pounds:
$(64) * (0.0625) = 4 pounds
$

27 ton to pounds:
$(27) * (2204.62) = 59524.74 pounds$
