Answers

okay so we can convert all of the numbers into the same unit so we can compare

jamail = 29.4%
andrew = 37.6%
ernesto = 28%
blake = 30%


in order from greatest to least,
andrew
blake
jamail
ernesto

Answer:

The order should be Andrew, Blake, Jamail, and then Ernesto (37.6%, 3/10, 29.4%, 7/25)

Step-by-step explanation:

You need the numbers to all be the same kind (ie. fractions or percentages) since there are more percentages, I decided to convert the fractions to percentages. This means that the denominators need to be 100. So, if we take Blake which is 3/10, than converting it to a percentage is easy. If you add a zero to both the numerator and the denominator, than you get 30/100 or 30%. For Ernesto, (7/25) multiply the numerator and the denominator by 4 to get 28/100 or 28%. Then, order them: 37.6%, 30%, 29.4% and 28%          Hope this helps!

Please please find the area for this polygon!

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.

Complete the table to determine the missing original prices and final cost of items A, B, C. D.

A $20 $???

B $??? $14

C $60 $???

D $??? $59

Answers

Answer:

See missing answers bold

$20 original = $5 final paid           as $15 was s/p before -10 was added

$30 original = $14 final price        as $24 was s/p before -10 was added

$60 original = $35  final price    as $45 was s/p before -10 was added

$92 original  = $69 final price       as $59  was s/p before -10 was added  

Step-by-step explanation:

Ans in bold  

A) = f(x) = 20(0.75) -10 =  15 - 10  = $5                 = £5 final paid

B)= f(x)  30 (0.75) = 24 - 10 = 14                           = $30 original price

C)  = f(x) = 60(0.75) -10 = 45 -10 = $35               = $35 final price

D)     = f(x) = 92 (75) = 69 -10 = $59                    = $92 original price
