The steps are more or less the same, except for one new addition:

1.Divide the tens column dividend by the divisor.

2.Multiply the divisor by the quotient in the tens place column.

3.Subtract the product from the divisor.

4.Bring down the dividend in the ones column and repeat.

a port and a radar station are 2 mi apart on a straight shore running east and west. a ship leaves the port at noon traveling no

Rom4ik [11]

Answer:

The rate of change of the tracking angle is 0.05599 rad/sec

Step-by-step explanation:

Here the ship is traveling at 15 mi/hr north east and

Port to Radar station = 2 miles

Distance traveled by the ship in 30 minutes = 0.5 * 15 = 7.5 miles

Therefore the ship, port and radar makes a triangle with sides

2, 7.5 and x

The value of x is gotten from cosine rule as follows

x² = 2² + 7.5² - 2*2*7.5*cos(45) = 39.04

x = 6.25 miles

By sine rule we have

$\frac{sin A}{a} = \frac{sin B}{b}$

Therefore,

$\frac{sin 45}{6.25} = \frac{sin \alpha }{7.5}$

α = Angle between radar and ship α

∴ α = 58.052

Where we put

$\frac{sin 45}{6.25} = \frac{sin \alpha }{x}$ to get

$\frac{x}{6.25} = \frac{sin \alpha }{sin 45}$ and differentiate to get

$\frac{\frac{dx}{dt} }{6.25} = cos\alpha\frac{\frac{d\alpha }{dt} }{sin 45}$

$\frac{15sin45 }{6.25cos\alpha } =\frac{d\alpha }{dt} }$ = 3.208 degrees/second = 0.05599 rad/sec.

I need to a paint a spherical storage tank in the pool. it has a radius of 8 feet and the paint cans i brought will cover 75 squ

Alexxandr [17]

<h3>Answer: 11 cans</h3>

======================================================

Explanation:

SA = surface area of the sphere

SA = 4*pi*r^2

SA = 4*pi*8^2

SA = 804.247719

The surface area is roughly 804.247719 sq ft.

I used the calculator's stored version of pi to get the most accuracy possible.

Since 1 paint can covers 75 sq ft, divide that surface area over 75 to find out how many cans you need.

804.247719/75 = 10.72330292

Round up to the nearest integer to get 11

You'll have leftover paint, but it's better to go over the goal than come up short.

In a multi-digit number, the number place that a digit is in determines it's?

slavikrds [6]

Answer:

PLACE VALUE

Step-by-step explanation:

To Find:in a multi-digit number, the number place that a digit is in determines it's?

Solution :

The number place that a digit is in determines it's PLACE VALUE

Definition of place value : Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.

Thus in a multi-digit number, the number place that a digit is in determines it's PLACE VALUE.

Eg . 389

Since the digit 8 is on tens place

So, it makes us to determine its place value

Place value of 8 is 80

Hence in a multi-digit number, the number place that a digit is in determines it's PLACE VALUE.
