Answer:

The number is n-0.75

Step-by-step explanation:

Here in this question, we are interested in giving a number which is 75% of 1 less than a number n.

The first thing we do here is to calculate the value of 75% of 1.

That would be;

75/100 * 1 = 0.75

So this value less than n will be;

n- 0.75

Annual income of A is 10% more than of B whereas income of B is 20% more than that of C. If monthly income of C is $ 2000 then w

Vanyuwa [196]

Answer:

7040

Step-by-step explanation:

C= 2000

B = 20/100 x 2000 = 400 + 2000 = 2400

A= 10/100 x 2400 = 240+2400= 2640

2000 + 2400 + 2640 = 7040

Nicole shines a light from a window of a lighthouse on a cliff 250 feet above the water level. Nick 10 feet above the water leve

Allushta [10]

Answer:

4585.8 feet

Step-by-step explanation:

If we draw the triangle, the opposite side to 3° angle would be "10" less than total height of 250 because Nick is 10 feet above water level, so that side will be:

250 - 10 = 240

The hypotenuse of the triangle is the length of line of sight. We can call this "x".

So, using trigonometric ratio of sine (opposite/hypotenuse), we can write:

$Sin(3)=\frac{240}{x}$

Now, we cross multiply and solve for x, line of sight length:

$Sin(3)=\frac{240}{x}\\x=\frac{240}{Sin(3)}\\x=4585.8$

2 cities have nearly the same north-south line 90° W. The latitude of the first city is 23°N, the latitude of the second city is

Ivan

Answer:

The cities are approximately 1452 km apart

Step-by-step explanation:

The two cities are on the same Longitude 90°W therefore the distance between them is on a great circle

Latitude of the first city = 23°N

Latitude of the second city = 36° N

Because their latitude are on the same polar axis, we subtract to get the angular difference

Angular Difference = 36 -23 =13°

$Distance= \frac{\alpha}{360} X 2\pi R$

where $\alpha = Angular Difference, R= radius of the earth$

$Distance= \frac{13}{360} X 2\pi X 6400=1452.11km$

The cities are approximately 1452 km apart
