Answer:

The correct answer is option A.  5

Step-by-step explanation:

It is given a rectangle ABCD

<u>To find the value of x</u>

It is given that,

AE = 5x - 10 and EC = 2x + 5

Since ABCD is a rectangle, All diagonals are equal.

AC = BD and AE = EC

AE = EC

5x - 10 = 2x + 5

5x - 2x = 5 + 10

3x = 15

x = 15/3 = 5

Therefore the correct answer is option A.  5

roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz. which best describes the percent of increase in
laila [671]

The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.

Step-by-step explanation:

The given is,

               Roberto score on math quiz at last week is 74

               This week he made an 85 on the quiz

Step:1

            Formula to calculate the percentage of increase the score,

                  Percentage of increase = \frac{Final score-Starting score}{Starting score} × 100...........(1)

            From the given,

                  Final score = 85

                  Starting score = 74

           Equation (1) becomes,

                  Percentage of increase =( \frac{85-74}{74}) ×  100

                                                       = (\frac{11}{74}) ×  100

                                                       = 0.1486486  ×  100

                                                       = 14.86486 %

                                                      ≅ 14.87 %

              Percentage of increase = 14.87 %

Result:

        The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.

college student are offered a 6% discount on a textbook that sells for $42.50. if the sales tax is 6%, find the cost of the text
Dvinal [7]

Answer:

$42.35

Step-by-step explanation:

The discount is 6% so in decimal form it is .06. Multiply that by the original amount $42.50.

42.5 x .06 = 2.55

That is the discount amount so you would subtract you from the original amount.

42.5 - 2.55 = 39.95

That is the cost of the textbook after the discount is applied. To apply the sales tax you would:

39.95 x .06 = 2.397

That is the tax amount so you would add it to the cost of the book.

39.95 + 2.397 = 42.347

Since we are talking about money you would round it to 2 decimal points.

$42.35

Similarly you could just do:

1.0 - .06 = .94

42.5 x .94 = 39.95

It will give you the same answer if you don't want to do it the first way.

Hope it helps! (:
