(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min
At the same rate, it would take Petra 56 minutes to jog 7 miles.
Answer:
(a) $248.285
(b) $249.441
(c) I will prefer to buy the television from online store.
Step-by-step explanation:
The manufacturing price of a television is $170.
(a) The online retailer charges a standard makeup of 27% and an additional 15% charge for shipping and tax.
Therefore the final price will be $
= $(170 × 1.27 × 1.15)
= $248.285
(b) Now, the superstore has makeup of 34% and then 9.5% charges for state tax.
So, the final price becomes $
= $(170 × 1.34 × 1.095)
= $249.441
(c) So, I will prefer to buy the television from the online store because the final price is less and also the shipping charges are included in the final price. (Answer)
Hello, thanks for using Brainly!
We are solving 6x6-4+9.
We will do three steps in this case.
First is 6x6, 6x6 is 30.
So now we must keep in our head we have 30 as our first number.
Now, let's -4 from 30. 30-4 is 26.
We just did step 2. Boom!
So, we have 26 as our second number. Let's do our third step.
If we have 26, we need to add 9 to that. To quickly find that we know that 26+10 is 36. That is adding ten, we need 9 so minus 1 from 36 we get 35.
Our final answer is 35.
126 divided by 2 = 63
63 x 3 = 189
b = 189
