(0.02A-0.01)/100=(0.005A-0.002)/100
multiply both sides by 100

0.02A-0.01 = 0.005A-0.002

0.02A - 0.005A = -0.002 + 0.01

i don't want to worry about all those decimals so i am going to multiply both sides by 1000

20A-5A = -2 +10

15A = 8

A = 8/15

The recent shut down of govt. funds has yet again proved to be more of hasty situations. There are now more unemployed citizens which is a cause for concern now. Well I hope the shutdown does not happen again.

x + 17.42 % = 4697 , How much is x & how do i calculate that?

x + 0.1742 = 4697

x = 6696.8258

but,

Are you sure you didn't mean x + 17.42% of x = 4697 ?

With a and b being the legs, and c the hypotenuse

Assuming this is a right triangle, you would use Pythagoras' Theorem
this is a ²+b ²=c2Depends.

Mega Movies hosted a film premiere on Friday night. They charged $8 for adults and $4 for children. One hundred seventy-three adults and children attended, and $1,276 was made in ticket sales. How many children and how many adults went to the film premiere?

Let a be the number of adults and c be the number of children

a + c = 173 => a =173 - c

8a + 4c = 1276

now substitute 173-c for a in the second equation and solve it.

can you finish it yourself?

7-(-10) = 7- - 10

Whenever two signs (+ or - ) are so close together that you can put a circle around them without anything else being in the way then

if the signs are the same replace them with a +
If the signs are different replace them with a -

So - - is replaced with a + (because the 2 signs are the same).

7- - 10 = 7+10 = 17

yes,
normally written
C=2*pi*r

It is just that if you put the 2 at the end it is more likely to be confused with A = pi*r^2

7a ²+25=6

subtract 25 from both sides and you get

7a ²=6-25 = -19

7a ²= -19

Divide both sides by 7

a ²= -19/7

You cannot find the square root of a negative number so there are NO 'real' answers

If you study maths for long enough you will find out about imaginary numbers where i=sqrt(-1)
so if you are considering imaginary numbers then you can keep going with your answer

a = +-Sqrt (-19/7)

= +- sqrt (19/7 * -1)

=+- sqrt(19/7) * sqrt(-1)

=+- sqrt (19/7) i

(which is the same answer that the administrator found)

What is the rule of these numbers 3/2, 1, 2/3, 4/9 and what are the next three numbers?

the next numbers are 8/27, 16/81, 32/243

Someone else can give the rule, or maybe just find the next 3 numbers

You need to know a little about calculus to find derivatives
The derivative of a curve is for calculating gradients of tangents at particular points on graphs.
Is that as clear as mud

and if what the admin posted makes no sense to you (like it did to me ) {a=-1.647508942095828i, a=1.647508942095828i}
and if that didn't show up the way i wanted it to, a = 1.647508942095828i
you know, you could have also just looked it up on the scientific calculator this website is based on. X3
have a awesome day!

you see, one millimeter is a tenth of a centimeter. so, if the centermeter version of 247mm would be a tenth of 247. and 247 divided by 10 is 24.7.
so your answer should be 24.7cm
