Hello there! So first off, let's find the tax. In order to find the tax of an item, all you have to do is multiply the price by the percentage, because the tax is the portion of the price. The tax is 4%. Let's solve. 20 * 4% (0.04) is 0.8. The tax is $0.80. Let's add that to the purchase price. 20 + 0.80 is 20.80. That's the total purchase price. Here are the answers easier to read.
Sales tax: $0.80
Total price: $20.80
Answer:4 100/477
Step-by-step explanation:You need to divide it.And first you change the mixed numbers 27 8/9 and 6 5/8 to improper fraction .27 8/9 as a improper fraction is 251/
9
. 6 5/8 as a improper fraction is 53/
8
.ANd now you divide 251/
9 by 53/
8.In order to divide fractions you need to do KCF which stand for Keep ,change,flip .SO you have 251/
9 divide 53/
8 ,now you KEEP 251/9 ,Change the division sign to multiplication ,and flip 53/8 to 8/53.And now you multiply 251/9 by 8/53 which gives you 2008/
477.Lastly you change 2008/
477 which is a improper fraction to a mixed number which is 4 100/477.
Answer:
The unknown number is 1.
Step-by-step explanation:
You have to form an expression. So let's make the unknown number as x. Firstly, a number is multiplied by 5 :


Secondly, 5 is added to product and you will get 10 :

Lastly, you have to solve :





The triangles are said to be similar, so the measures of sides in the larger triangle are proportional to the measures of sides in the smaller triangle. The measures of the two long sides have the ratio 182:65, so we expect the ratio of the shortest sides to be the same:
... ? : 45 = 182 : 65 . . . or . . . ?/45 = 182/65
Multiplying the equation by 45 gives us
... ? = 45·(182/65) = 126
The appropriate choice is ...
... C. 126
