Answer:
area is length * width, so
5x10^5 * 4x10^4
multiplication is commutative, so that's
5*4 * 10^5*10^4
= 20 * 10^9
= 2*10^10 m^2
if the powers stuff is confusing, it's just shorthand for multiplication
10^5*10^4 = (10*10*10*10*10)*(10*10*10*10) = 10^9
just as multiplication is shorthand for addition
5*4 = 5+5+5+5
Answer:
the additive inverse of 1 is 1 because 1+1=0 and the multiplicative inverse of 1 is 1.
Step-by-step explanation:
0.116666666666667 you can use a regular calculator
The sum of functions is given as:
In this case we have:
![(f+g)(x)=5x+\sqrt[]{x-1}](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D5x%2B%5Csqrt%5B%5D%7Bx-1%7D)
The domain of the functions is any number that makes the squared root a real number, then:
Hence the domain of the functions is:
Answer:
After buying the meal and the computer game, Kristian has 43.33% of his money left.
Step-by-step explanation:
Given that Kristian buys a meal for $ 8.40, to calculate the fraction of the $ 72 after buying the computer game which cost $ 32.40 and the meal, the following calculation must be performed:
72 = 100
8.40 + 32.40 = X
72 = 100
40.80 = X
40.80 x 100/72 = X
4,080 / 72 = X
56.66 = X
100 - 56.66 = 43,333
Therefore, after buying the meal and the computer game, Kristian has 43.33% of his money left.
