Step-by-step explanation:
Scale factor of STUV to S'T'U'V
= Length of T'U' / Length of TU
= 6/12 = 0.5.
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%
Total cost = price + tax
Tax = 7 1/4 % of price
Tax rate = [7 + 1/4] = 7.25 %
Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51
Total cost = $89.75 + $ 6.51 = $96.26
he equation of any horizontal line is
y = .. a number
The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.
In this case the line passes though the point (−8,9)
which tells us that the y-value we want is 9.
Therefore the equation is y=9
It should be 0.4 cause 0.4 is the same as 0.40
-8/5 is a rational number because in order to be a rational number it must be able to be written as a fraction. -8/5 is a fraction; therefore, the negative does not affect it.
