Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².
Answer:
Myron received 40% votes.
Step-by-step explanation:
Myron receives 10 votes from his class of 25 students and we have to calculate the percentage of the vote received.
Now we will use unitary method to calculate the percentage.
∵ Out of 25 students Myron received votes of = 10 students
∴ Out of 1 student Myron received votes = 10/25 students
∴ Out of 100 students Myron received votes = 10×100/25 = 40%
Myron received 40% votes.
<u>Given</u>:
The given expression is 
We need to determine the value of x using either base - 10 or base - e logarithms.
<u>Value of x:</u>
Let us determine the value of x using the base - e logarithms.
Applying the log rule that if 
then 
Thus, we get;
Applying the log rule, 
, we get;
Expanding, we get;
Subtracting both sides by 
, we get;
Subtracting both sides by 
, we get;
Taking out the common term x, we have;
Thus, the value of x is
