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
Answer:
22 1/2
Step-by-step explanation:
Consider the expression

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

Expand the denominator:

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

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

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.
