The 4th option is correct
Answer:
hello : (D.) 6x + 3
Step-by-step explanation:
(4x+3) + 2x = 4x + 3 +2x = ( 4x+2x)+3 = 6x+3
Answer:
Area of trapezium is 24cm²
Step-by-step explanation:
The Perimeter of rectangle ABCF = 20 cm
One of the sides AB = 6 cm (AB)(Let it be L)
Let the other side of Rectangle be B.
We know that Perimeter of Rectangle = 2 (Length + Breadth)
So,
20 = 2(L+B) = 2(6 + B)
= 6+B
10 = 6+B
B = 10-6
B = 4cm
Breadth of Rectangle, B = 4cm (BC)
Length of side of trapezium, CD = BD - BC = 9 - 4= 5cm
And length of EF = 3 cm
Now, Sides, AB and EC act as Perpendicular for Trapezium CDEF (Sides of Rectangle are perpendicular to each other)
We know that,
Area of Trapezium = ½ × (sum of parallel sides )×height
= ½×(CD + EF)× CF
= ½×(5+3)×6
= 8/2 ×6
= 4×6
= 36 cm²
Area of trapezium = 24cm²
Based on the time spent per project and the number of projects, the average time spent per outsourced project is <u>271 hours. </u>
<h3>Time spent on all projects</h3>
The time spent on all the projects can be found by the formula:
<em>= ∑( Number of projects in continent x Average time per project) </em>
Solving gives:
= (13 x 278) + (6 x 382) + (4 x 279) + (7 x 148) + ( 3 x 298)
= 8,952 hours
<h3>Number of projects </h3>
<em>= ∑Projects per continent </em>
= 13 + 6 + 4 + 7 + 3
= 33 projects
<h3>Average Time Spent </h3>
This is then found as:
<em>= Time spent in total / Number of projects </em>
= 8,952 / 33
= 271 hours
In conclusion, 271 hours was spent on average.
