Kevin needs to buy some cardboard to build a box 11 inches long, 7 inches wide, and 10 inches high. How much cardboard is needed to build the box?

Answers

Answer:

770 inches of cardboard is needed to build this box

Step-by-step explanation:

7 x 11 x 10 = 770

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?

Answers

Answer:

40 waves

Step-by-step explanation:

Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%

Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40

Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.

Jasmine had an average daily balance of $1,608.24 for the last billing cycle, which had 31 days. If her credit cards charges an APR of 22.99%, what would her finance charges be for the last billing cycle?

Answers

Answer:

Finance per billing cycle = $ 30.91

Step-by-step explanation:

First, we will calculate the APR for 1 day:

APR per day = (22.99%/year)(1 year/12 month)(1 month/31 days)

APR per day = 0.062 % / day

Now, we will calculate the finance per day:

Finance per day = (Daily Balance)(APR per day) = ($ 1608.24)(0.062 %/day)

Finance per day = $0.99/day

Now, we will calculate the finance for one billing cycle:

Finance per billing cycle = (Finance per day)(31 days) = ($ 0.99/ day)(31 days)

Finance per billing cycle = $ 30.91

Find the value of x.

Answers

Answer:

x = 4

Step-by-step explanation:

The angle next to (adjacent to) 19x + 3 is 180 degrees less (19x + 3):

180 - (19x + 3)

and the three interior angles of the triangle must sum up to 180 degrees:

11x - 2 + 180 - 19x - 3 + 9x + 1 = 180, or

11x - 2 - 19x - 3 + 9x + 1 = 0

Combining like terms, we get:

x = 4
