Answer:

4000

Step-by-step explanation:

from 1 - 1000 = 300

1's = 100

10's = 100

100's = 100

1000's = 0

300 * 10 = 3000

then add in all the 3000's (ie 3001,3002, etc ) that adds one more thousand

3000 + 1000 = 4000

If A=(0,0) and B=(8,2), what is the length of AB

NeX [460]

Answer:

$\boxed{\sf Distance_{AB}= 8.24 \ units }$

Step-by-step explanation:

Here two points are given to us and we need to find the distance between the two points . The given points are , A(0,0) and B(8,2) . The distance between the two points can be found out using the Distance Formula , which is ,

Distance Formula:-

$\sf\implies \green{ Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}}$

Therefore on substituting the respective values ,we can find the Distance as ,

$\sf\longrightarrow Distance = \sqrt{ ( 0 - 8)^2 + (0-2)^2}$

Simplify the brackets ,

$\sf\longrightarrow Distance =\sqrt{ (-8)^2+(-2)^2}$

Square the numbers inside the squareroot ,

$\sf\longrightarrow Distance =\sqrt{ 64 + 4}$

Add the numbers inside the squareroot ,

$\sf\longrightarrow Distance = \sqrt{68}$

Find the value of squareroot,

$\sf\longrightarrow \boxed{\blue{\sf Distance = 8.24 \ units }}$

Hence the distance between the two points is 8.24 units .

Romashka [77]

In a division problem, ...

... dividend / divisor = quotient

Multiplying both sides of this equation by "divisor", we get ...

... dividend = quotient × divisor . . . . . . . . the desired relationship

The for dividend = 1/8, divisor = 6, and quotient = 1/48, this becomes ...

... 1/8 = 1/48 × 6

... 1/8 = 6/48 = 1/8 . . . . . the given values are consistent

How do I solve this. Please help!!

11111nata11111 [884]

Answer:

x = 4 $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = $\frac{1}{\sqrt{2} }$ , then using the upper 45°

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{4}{x}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x = 4 $\sqrt{2}$
