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

What is the slope of 5x-y =2

hodyreva [135]

Answer:

Step-by-step explanation:

To find the slope, rearrange the terms of this equation to y=mx+b form, where m is the slope.

Original equation: 5x-y=2

Subtract 5x to both sides: -y = -5x+2

Multiply both sides by -1: y = 5x-2\

This gives us the slope, which is equal to 5.

Let me know if this helps!

Converting units is always an exercise in linear relationships. how many inches is 2.50 m? (2.54 cm=1.0 inch)

madam [21]

There are 98.4252 inches in 2.50m.

Unit Conversion is defined as a process that involves multiplication and division by a numerical factor or a particular conversion factor.

For Example .Convert 2m into cm.

As we know that 1m=100cm

multiplying both sides by 2 we get

2m = 200 cm.

According to the question

It is given that 2.54 cm = 1 inch

$1cm = \frac{1}{2.54} inch$

$100cm=\frac{100}{254} inch$

$1m = \frac{100}{2.54}$ ( as 100cm = 1m)

we need 2.50 m So we multiply both sides by 2.50

$2.50m=\frac{2.50*100}{2.54} \\\\ 2.50m=\frac{250}{2.54}$

$2.50m=98.4252 inch$

Therefore , there are 98.4252 inches in 2.50m.

Carrie buys 4.16 pounds of apples for 5.20 how much does 1 pound cost

JulijaS [17]

4.16 / 5.20 = 1 / x.....4.16 lbs to $ 5.20 = 1 lb to $x
cross multiply because this is a proportion
(4.16)(x) = (5.20)(1)
4.16x = 5.20
x = 5.20 / 4.16
x = 1.25 per lb <==
