-8 3/8 = -8 15/40
-12 4/5 = -12 32/40 ,because you had to get a common denominator.
Since you are subtracting from a negative the negative turns into a positive.
-8 15/40 + 12 32/40 = 4 17/40
We can make and use the equation: <em>A = 160( 1.03 )^y</em>: A = amount, 160 = amount put in, 1 + .03 = 1.03 = interest, and y as the number of years, as the money is compounded every year. (This is the compound interest equation, but I put in the numbers)
A) 160 * 1.03 = $164.80, 160 * 1.03² = $169.744 ≈ $169.74
B) 160 * 1.03⁵ = 185.48385 ≈ $185.48
The expression is the same as saying (((((160 * 1.03)1.03)1.03)1.03)1.03). This is like multiplying 160 * 1.03, which gives the amount for the first year. Then, that amount is multiplied by 1.03, which is the amount for the second year. This isi repeated until 5 years.
C) 160(1.03)³⁰
I'm pretty sure that mean and average both mean(pun not intended) the total value of the data divided by the number of values, giving you an average.
Mode is the value that is repeated most often. For example, if your data set is 1, 3, 4, 2, 2 the mode is 2 because it is repeated twice. If there was another 3, 4, or 1 then the mode would be both values, as they both were repeated the most often.
Hope this helped :)
B, the total area of wall space to be covered.
Perimeter is like fencing, that won't tell us how much wall there is to paint.
They are both decimals.
But 0.04 > 0.004.
