Answer:
<em>1) 6%</em>
<em>2) $1,689.35</em>
Step-by-step explanation:
1) Given the following
Sales tax = $64.80
Price of the computer = $1080
Required
rate of sales tax
Using the expression
x% of 1080 = 64.80
x/100 * 1080 = 64.80
10.80x = 64.80
x = 64.80/10.80
x = 6%
<em>Hence the rate of sales tax is 6%</em>
<em></em>
2) Given the following
Price of the car = $25,990
Tax rate = 6.5%
Sales tax charged = 6.5% of $25,990
Sales tax charged = 6.5/100 * 25,990
Sales tax charged = 6.5 * 259.9
Sales tax charged = $1,689.35
<em>hence the sales tax being charged is $1,689.35</em>
Arranging units from smallest to largest:
pm, nm, um, mm, cm, dm, m, km.
Individual measurements in terms of 1 meter.
1 x 10^12 pm = 1 m
1 x 10^9 nm = 1m
1 x 10^6 um = 1m
1 x 10^3 mm = 1m
1 x 10^2 cm = 1m
1 x 10^1 dm = 1m
1m = 1m
1 x 10^-3 km <span> = 1m</span>
