Question #5: You decided to paint one of the walls in the dining room the color blue. The shape of the wall is shown below. One gallon of paint covers 50 square feet. The wall will need two coats of paint. How many gallons of paint will you need to buy?

Total area of the wall:

Gallons of paint needed:

Answers

Answer:

Step-by-step explanation:

Draw a horizontal line from the top corner of the left wall to the right wall. Now you have a rectangle on the bottom 8’x10’ (80 square feet) and a triangle on the top with a height of 5’ and a base of 8’. 1/2 base times height =20. You need to paint 100 sq feet so you need 2 gallons.

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

What type of triangle is this triangle?
acute isosceles
obtuse isosceles
Right isosceles
acute scalene

Answers

Obtuse isosceles
it has 2 congruent sizes, no right angles and seems two big to be acute

Answer:

obtuse isosceles

Step-by-step explanation:

An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.

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
