What are some proxy sites that are not blocked by Lightspeed Systems?

tatyana61 [14]

Most proxy sites eventually get blocked. What you can try is using a Tor browser, or translating websites names using web translators such as google translate. The most boring thing to do would be just to open a find page from google and try out one at a time.

You are making several purchases from the I.B. Electric electronics store. You can buy from this store online or in a physical s

hammer [34]

Answer:

Online store will save the most money

Step-by-step explanation:

Amount used in Physical store

Batteries 2packs @$5.99 cost = $5.99*2=$11.98

Stereo 1 system @$100 cost = $100*1=$100

CDs 3 CDs @$7.95 cost = $ 23.85

Total cost= $11.98+$100+$23.85= $135.83

Applying the 10% off coupon = 90/100 * $135.83 =$ 122.25

Applying sale tax 5% = 105/100 * 122.25=$128.36

Amount to spend when using physical store= $128.36

Now calculate for the online store

Batteries 2packs @$4.99 cost= $4.99*2=$ 9.98

Stereo 1 system @$90 cost= $ 90 *1= $90

CDs 3 CDs @$8.95 cost = $8.95*3=$26.85

Total cost=$9.98+$90+$26.85=$126.83

Applying the 5% off coupon= 95/100*126.83=$120.49

Applying the sale tax, $6.99+$120.49=$127.48

Comparing the two ways,

Physical store= $128.36

Online store=$127.48

Online store will save the most money by ($128.36-$127.48)=0.88

The table shows formulas for the recommended heart rates during exercise for a person who is "a" years old. Write and solve a co

Naily [24]

Answer:

102 ≤ heart rate ≤ 183.6

Step-by-step explanation:

... lower limit ≤ heart rate ≤ upper limit

Put 16 where "a" is and do the arithmetic.

... lower limit = 0.5(220 -16) = 102

... upper limit = 0.9(220 -16) = 183.6

Then the inequality is ...

... 102 ≤ heart rate ≤ 183.6

Comment on the problem

There is nothing to "solve" here. One only needs to evaluate the limits.
