Find the value of 815×213 Although these numbers aren't quite as nice as the ones from the example, the procedure is the same, s

ANEK [815]

Answer:

The answer is 173,595‬

Step-by-step explanation:

Firstly, you multiply 815 by the first number of 213 which is 3

So:

$815* 3=2445\\$

Then 815 by the second number:

$815* 1=815\\$

Then 815 by the third number:

$815* 2=1630\\$

Then you add all the numbers, but you have to put a zero to the right of the second product and two zeroes to the third product and so on..

In this case the addition is :

2445+8150+163000 = 173595

11. Suppose a force F varies as the product of two masses, m and M, inversely as

almond37 [142]

Answer:

$k = 6.74 * 10^{-5}$

Step-by-step explanation:

Given

$F\ \alpha\ \frac{m * M}{r^2}$ --- The variation

$F = 675; m = 125; M = 225; r = 0.0530$

Required

Determine the constant of proportionality (k)

$F\ \alpha\ \frac{m * M}{r^2}$

Express as an equation

$F = k\frac{m * M}{r^2}$

Multiply both sides by $r^2$

$Fr^2 = km * M$

Make k the subject

$k = \frac{Fr^2}{m * M}$

Given that: $F = 675; m = 125; M = 225; r = 0.0530$

We have:

$k = \frac{675* 0.0530^2}{125 * 225}$

$k = \frac{1.896075}{28125}$

$k = 0.000067416$

This can be represented as:

$k = 6.74 * 10^{-5}$
