Answer:

  • m∠J = 76°
  • m∠K = 65°

Step-by-step explanation:

The sum of angle measures is ...

  (7x +13)° +(83 -2x)° = 141°

  5x +96 = 141 . . . . . collect terms, divide by °

  5x = 45 . . . . . . . . . subtract 96

  x = 9 . . . . . . . . . . . divide by 5

  7x +13 = 7·9 +13 = 76 . . . . . find m∠J

  m∠J = 76°

  m∠K = 141° -76°

  m∠K = 65°

Tv emporium had a huge sale in the morning 5/12 of the flat screen televisions were sold in the afternoon one-third of the flat
lara [203]

Answer:

Total number of flat screen sold is 3/4

Step-by-step explanation:

Let the total number of the flat screen sold be y

y = number of flat screen sold in the morning + number of the flat screen sold in the afternoon.

Number sold in the morning = 5/15

Number sold in the afternoon = 1/3

Y = 5/12 + 1/3

Find the LCM of 12 and 3

Y = (5 + 4)/12

Y = 9/12

Y = 3/4

Total number of flat screen sold is 3/4

The fraction a/b is in simplest terms and equal to the following:((2020^3)-1)/((2021^3)+1) . What is a + b?
blagie [28]

Consider the expression

\dfrac{x^3-1}{(x+1)^3+1}

Factorize the numerator and denominator a difference/sum of cubes:

\dfrac{(x-1)(x^2+x+1)}{((x+1)+1)((x+1)^2-(x+1)+1)}

Expand the denominator:

\dfrac{(x-1)(x^2+x+1)}{(x+2)((x^2+2x+1)-(x+1)+1)}=\dfrac{(x-1)(x^2+x+1)}{(x+2)(x^2+x+1)}=\dfrac{x-1}{x+2}

since <em>x</em> = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of <em>x</em> ² + <em>x</em> + 1. This leaves us with

\dfrac{2020^3-1}{2021^3+1} = \dfrac{2020-1}{2020+2} = \dfrac{2019}{2022}=\dfrac{673}{674}=\dfrac ab

so that <em>a</em> + <em>b</em> = 673 + 674 = 1347.

A right rectangular prism is 5 and 1/4 inches wide 12 and 1/2 inches long and 4 inches tall what is the volume of the prism
Goryan [66]

Answer:

29 in ^3

Step-by-step explanation:

6 sides

2 of which are smaller than the other 4.

12 x 1/2 x 4 = 4 longer sides

5 x 1/4 x 4 = 2 shorter sides

12 x 1/2 = 6

6 x 4 = 24

5 x 1/4 = 1.25

1.25 x 4 = 5

5 + 24 = 29

29 in ^3

3. Nolan drew a right triangle. How many<br>acute angles did he draw?​
Pachacha [2.7K]

Answer:

Two acute angles

Step-by-step explanation:

The right triangle has one 90 degree angle and two acute angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.
