PLEASE HELP NO TROLLS<br> 3. Find the measure of angle A.

Georgia [21]

Answer:

35

Step-by-step explanation:

Since this triangle is a 90 degree angle, all you'd have to do is subtract 55 from 90 and you've got you answer.

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.

11111nata11111 [884]

Answer: PART A.

y= remaining height of candle

x= rate the candle burns down in inches per hour

8= original height of candle

the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.

You can use this function to create ordered pairs by putting in number at x which indicates the time:

x=1

y=8- (.5×1)= 7.5

(1, 7.5)

you can then do this for other numbers and get:

(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)

PART B.

This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)

PART C.

If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.

Step-by-step explanation: hope this helps

A ladder 20 feet long leans against a building forming and angle of 46 degrees with the level ground. To the nearest foot how fa

sleet_krkn [62]

Answer:

The distance of the foot of the ladder to the building is 14 ft.

Step-by-step explanation:

The length of ladder = 20 ft

Angle formed by ladder with level ground, θ = 46

We are required to find out the distance of the foot of the ladder from the building

The above question can be found out by using trigonometric relations as follows;

$Cos\theta = \frac{Adjacent\, side \, to\, angle}{Hypothenus\, side \, of\, triangle}$

The adjacent side of the right triangle formed by the ladder the building and the ground is the distance of the foot of the ladder from the building

The hypotenuse side is the length of the ladder = 20 ft

Therefore;

Adjacent side of triangle = Hypotenuse × cosθ

∴ Distance of the foot of the ladder from the building = Hypotenuse × cosθ

Distance of the foot of the ladder from the building = 20 ft × cos(56)

Distance of the foot of the ladder from the building = 13.893 ft

To the nearest foot, the distance of the foot of the ladder to the building = 14 ft.

A two gallon container had all of its dimensions tripled. How many gallons does the new container hold?

Vaselesa [24]

Answer:

8

Step-by-step explanation:

In this situation if the two gallon container will have all of its dimensions tripled, then that means the the volume of the container will also get tripled.

When all the dimensions of a shape are changed, the volume will then also change accordingly.

Since the original container held 2 gallons, we will then solve for the value by simply raising 2 to the power of 3.

2³ = 8

Now why did we raise the number of gallons by three instead of multiplying it directly by 3?

We did that, because we need to consider that the entire container had all of its dimensions tripled. When a shapes dimensions are all increased, this means that it will grow exponentially.
