9.original cost: $35 new cost: $38.22
what is the percent increase

Answers

Answer: for the first one it is 22 percent

Step-by-step explanation: first I found out that 14.08 is In-between 64 and 78.08 . Then I devided 14.08 by 64 so I got 0.22 then i made that a percentage by multiplying it by 10. So the answer is 22 percent. Please mark me brainiest.

I did it on the other one but here is the full explanation

The second one is $25 because 23.36 times 7% equals 1.36 then add 23.36 and 1.36 and you get $25

Arwa is playing 'Guess my number'. Arwa says: 'If I add 0.4 to my number, divide the answer by 8, then multiply that answer by 9, I get 0.9.' What is Arwa's number?

Answers

0.4 is the answer because you if you work backwards and use inverse operations you get 0.4.
meaning, if you divide 0.9 by 9, you get 0.1. when you multiply 0.1 and 8 you get 0.8. and when you subtract 0.4 from 0.8 you get your answer, 0.4.

Answer: it should be 8.

Step-by-step explanation:

Step 1. Factor in the given variables.

(xy + 1) ÷ 7 becomes ((5)(11) + 1) ÷ 7

Step 2. Do the first part in parentheses

so (5) x (11) which is 55.

Step 3. Add together the full parentheses

so 55 + 1 which is 56

Final step, divide.

56 divided by 7 equals 8.

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.
