Answer:

70°C

Step-by-step explanation:

First, fill in the variable that you know (F) with 158. Now you have the equation C= 5/9 × (158 - 32). According to PEMDAS, you solve parentheses first, so you get C= 5/9 × (126). Next, you do multiplication, which is 5/9 × 126. To make it simpler, you can do 5/9 × 126/1, then you can simplify it further to 5/1 × 14/1 to get 70/1 or 70.

Answer:

70 C

Step-by-step explanation:

C = 5/9 * (F-32)

substitute F = 158

C = 5/9 ( 158-32)

Parentheses first

= 5/9 (126)

= 70

-6.3x+14 and 1.5x-6<br> answer in simplified form

koban [17]

Answer:

The simplified form of -6.3x+14 and 1.5x-6 is -4.8x+8

Step-by-step explanation:

We have to simplify the following

-6.3x+14 and 1.5x-6

it can be written as:

=(-6.3x+14) + (1.5x-6)

Adding the like terms

=(-6.3x+1.5x)+(14-6)

= (-4.8x)+(8)

= -4.8x+8

So, the simplified form of -6.3x+14 and 1.5x-6 is -4.8x+8

Silvio is an air-traffic controller who must calculate the altitude of an incoming plane. He sees the plane at an angle of eleva

Mrac [35]

Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let $h$ the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.
$tan \alpha = \frac{opposite.side}{adjacent.side}$
$tan(40)= \frac{h}{3}$
$h=3tan(40)$
$h=2.5miles$

We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is $h=3tan(40)$ .
