In Minnesota, the state sales tax rate is 6.875%. The price tag on an HDTV gives
torisob [31]

Answer:

1560.38

Step-by-step explanation:

As far as I know, a sales tax is never calculated until money changes hands. So the rebate is the first amount to take place.

1560 - 100 = 1460

Now if the purchaser agrees to this amount and does anything to pay partially or in full, the tax is added.

Total Cost = 1460 * (1.06875)

Total Cost = 1560.38

Edit

You have to be very careful when you use a term like rebate. Rebate is a very special kind of discount. Your purchase has to qualify for a rebate. Apparently this one does. If you are willing to spend 1560 on something, the merchant selling the product offers you a rebate to help you decide.

If the TV cost is 1200 you may not get the rebate.

A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadil
Reika [66]

Answer: The fraction would be 0.53.

Step-by-step explanation:

Since we have given that

r(t)=A.(1.05)^t

where, A is the constant initial production rate

t is the time.

For 98 years, the production rate in motorcycles per year would be

r(98)=A.(1.05)^{98}\\\\r(98)=A.119.27

For 13 years, the production rate in motorcycles per year would be

r(98-13)=r(85)=A.(1.05)^{85}\\\\r(85)=A.63.25

So, the fraction of their total production was built during the last 13 years would be

\dfrac{r(85)}{r(98)}=\dfrac{63.25}{119.27}=0.53

Hence, the fraction would be 0.53.

Select point B, and drag it. As you drag B, circle AB changes. Verify that you can make circle AB coincide with AC. Return B to
-BARSIC- [3]

Answer:

When AB coincides with AC, the boundary of EAF maps exactly onto the boundary of CAD, implying that EAF dilates into CAD. So, the boundaries of EAF and CAD are similar.

The proportional relationship may be stated in different forms, but should be equivalent to this equation:

radius of Ab/ radius of Ac= length of arc EF/ length of arc CD

Explanations will vary, but should be based on the similarity of EAF and CAD. The proportional relationship follows from the fact that corresponding pairs of lengths in two similar figures have the same ratio.

Step-by-step explanation:

This is the exact answer so make sure you change it up a little.
