In 2012, five U.S. Postal stamps cost $2.20. How much did seven stamps cost? (Hint, find the unit rate first) $

Answers

Answer 1

Answer:

$3.08 for 7 stamps  

Step-by-step explanation:

The unit rate (price per stamp) is:

$2.20

-------------- = $0.44/stamp

5 stamps

Then 7 stamps would cost:

 $0.44          

------------ * 7 stamps = $3.08 for 7 stamps  

1 stamp

Please help if you can!!!

Answers

Answer:

Step-by-step explanation:

y = ax² + bx + c

Plug in the three given points, then solve for a, b, c

(-3,0): 0 = 9a - 3b + c

(4,0): 0 = 16a + 4a + c

(0,-12): -12 = c

9a - 3b = 12

3a - b = 4

16a + 4b = 12

4a + b = 3

a = 1

b = -1

y = x² - x - 12

Answers

5k + 30 = -20 - 5k

5k + 5k = -20 - 30

10k = -50 / : 10

k = -5

Answer:

-5 = k

Step-by-step explanation:

5k + 30 = -20 - 5k

5k + 30 + 20 = 5k + 50

-20 - 5k + 20 = -5k

5k + 50 = -5k

5k + 50 - 5k = 50

-5k - 5k = -10k

50 = -10k

50 / -10 = -5

-10k / -10 = k

Scores on a national math test are Normally distributed, with a mean score of 490 and a standard deviation of 50. Which test score represents the top 20%, rounded to the nearest whole number?

Find the z-table here.

426
448
532
554

Answers

Answer:

532

Step-by-step explanation:

The score that represents the top 20% = A score = 80%

Z score for 80% percentile = 0.842

We solve using the z score formula

z = (x-μ)/σ, where

x is the raw score = ??

μ is the population mean = 490

and σ is the population standard deviation = 50

Hence:

0.842 = x - 490/50

Cross Multiply

0.842 × 50 = x - 490

x = 0.842 × 50 + 490

x = 42.1 + 490

x = 532.1

Approximately = 532

Therefore, the test score = 532

the length of a rectangle is 2 inches less than 3 times it width . The perimeter of the rectangle is 124 inch. WHat is the length of the rectangle

Answers

Step-by-step explanation:

let w = width

length = 3w-2

perimeter = 2*length + 2*width

perimeter = 2(3w-2) + 2w

perimeter = 6w - 4 + 2w

perimeter = 8w - 4

perimeter = 124 inch

8w - 4 = 124inch

+4 to each side

8w = 128inch

divide each side by 8

w = 16

length = 3w-2

           = 3(16) - 2

length = 46 inch
