You decide to take your car on a drive through canada, where gas is sold in liters and distances are measured in kilometers. sup

Darya [45]

Alright, lets get started.

Lets convert the efficiency of the car from miles/gallon to kilometers/liters.

$32*\frac{1}{0.6214*3.78} \frac{km}{liter}$

13.62 km/liter

For 13.62 km, it takes gas = 1 liter

For 410 km, it takes gas =

$\frac{410}{13.62}$ = 30.10

30.10 liters of gas will you need to complete a 410.0 km trip. : Answer

A plane is flying at an altitude of 25,000 m. From the pilot, the angle of depression to the airport tower is 30°. How far is th

maria [59]

The question is modelled as shown in the diagram below

We have the angle, 30° and we know the length of the side opposite the angles, 25000 feet. We are looking for the ground distance between the plane and the tower. We will use the trigonometry ratio of Tan

$tan(x)= \frac{opposite}{adjacent}$
$tan(30)= \frac{25000}{y}$
$y= \frac{25000}{tan(30)}$
$y=43301.27019$

The distance between the point directly beneath the plane and the tower is 43301.3 feet (rounded to 2dp)

The triangles shown have the same perimeter. What is the value of x?

olga nikolaevna [1]

Answer:

Step-by-step explanation:

Since you know the perimeters are equal, write your equation.

x+6 + x+6 + x+6 = x + x+6 + 2x-6

combine like terms

3x + 18 = 4x

isolate your x by subtracting 3x from each side

18 = x

check your answer:

3x + 18 = 72

4x = 72

IVa wantd to train for a race by runing 10km ober 3 days uring the week. The first day she ran 1.37 km more than she aran on the

makkiz [27]

Answer: she ran 3.53km on the third day.

Step-by-step explanation:

Let x represent the number of miles that she ran on the second day.

The first day, she ran 1.37 km more than she ran on the second day. This means that the distance that she ran on the first day is

x + 1.37

On the third day, she ran 0.98 km more than the second day. This means that the distance that she ran on the third day is

x + 0.98

The total distance that she wants to run in 3 days is 10km. This means that

x + 1.37 + x + x + 0.98 = 10

3x + 2.35 = 10

3x = 10 - 2.35

3x = 7.65

x = 7.65/3

x = 2.55

The distance that she ran on the third day is

2.55 + 0.98 = 3.53 km
