Log(100) = log(400) - log(4)<br> "

Luden [163]

When working with logarithms, remember that a subtraction sign means you can divide.
log(400) - log(4) can be turned into log(400/4), which is further simplified to log(100).

Suppose j varies jointly with g and v, j=1 when g=6 and v=3. Find j when g=8 and v=11

Lady bird [3.3K]

j=4.88 when g=8 and v=11

Further explanation:

When the increase/decrease in one quantity cause increase/decrease in other quantity, it is called direct variation.

Variation is always accompanied by a variation constant.

<u>Given</u>

g and v vary directly with j

IT can be written as:

j∝gv

Putting the variation constant k

j = kgv

Putting g = 6 and v=3

$j = kgv\\1 = k * 6 * 3\\1 = 18k\\k = \frac{1}{18}$

So the value of k is 1/18 which makes the equation

$j = \frac{1}{18}gv\\ Putting\ g=8\ and\ v=11\\j = \frac{1}{18} * 8 * 11\\j = \frac{88}{18}\\ j =4.88$

So, j=4.88 when g=8 and v=11

What is c/22 + 668 = 684 I NEED HELP!!!!!!!!!!!!!!

scoundrel [369]

Answer:

352

Step-by-step explanation:

So first you need to subtract 668 from both sides.

c/22 + 668 = 684

-668 -668

---------------------------

c/22 = 16

Then multiply both sides by 22.

c/22 * 22 = 16*22

c = 352

Check-

352/22=16

16+668=684
