Here is an idea tertre....instead of us doing your homework......why don't you try to solve the problems and post your attempts here and we will see how you are doing and help you along ??? Cool?
48 is to 40% as 'x' is to 100% ?
48/40% = x/100% Multiply both sides by 100%
120=x
2x-2=x+2 Add 2 to both sides of the equation to get:
2x = x+4 Now subtract x from both side to get
x = 4
100% is the 'entire enchilada' 100% of 200 is 200.
Use the cosine function , which is adjacent/hypotenuse
cos(YZX) = 7.5/22.3
=7.5/22.3 = 0.336322869955157
Arcos(YZX)=70.35 degrees
what is (2+sqrt(2))-(3+2sqrt(2)) First remove the ()
2+ sqrt 2 -3 -2sqrt 2 then collect 'like' terms
2-3 + sqrt 2 - 2 sqrt 2
-1 - sqrt 2
Example:
After TWO years the pop would be 25000 (1+i)^n where i= % growth rate per year in DECIMAL and n= number of years
= 25000(1+.012)^2
If it asks for months you will have to change the interest rate to a MONTHLY rate i/12 and n= months
Yes....hit the ' 2nd ' button first....the tan button will become atan which is tan^-1
c pounds / m people = c/m pounds per person if you add n you must add this amount per n
c/m x n = n c/m d would be the answer
acceleration is change in velocity over time (m/s^2)
4 m/s / 2.5 s = 1.6 m/s^2 = her acceleration
