Answer:
if a= (1/27)^2 + 3, then a is about 3.00137
Step-by-step explanation:
I assume you have a typo here.
Your equation should be a = (1/27)^2 + 3 ...
If that is so, a = (1/27)^2 + 3 = 3.00137...
The measure of the value of x is 49.5 degrees, the correct option is B.
Given
The measure of arc QS is (4x – 18)°.
<h3>The measure of arc</h3>
Arc QS is a semicircle and hence subtended angle by semicircle at the center is 180 degrees.
The measure of the arc QS is (4x – 18)° is equal to 180 degrees.
Then,
The value of x is;
Hence, the measure of the value of x is 49.5 degrees.

Answer:
Total number of students receiving A grade = 75
Step-by-step explanation:
Total number of students enrolled in elementary algebra this year =300
Percentage of students receiving a grade of A = 25%
To find number of students that will receive a grade of A.
Solution:
In order to find the number of students that will receive a grade of A, we will find the percentage students receiving A grade of the total number of the student.
Number of students receiving A grade =
⇒
Writing 25% as fraction and multiplying.
⇒
⇒
⇒
∴ Total number of students receiving A grade = 75 (Answer)
To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets ("or") or an intersection of sets ("and"). Then, solve both inequalities and graph. To find the solution of the compound inequality, we look at the graphs of each inequality and then find the numbers that belong to both graphs—where the graphs overlap. For the compound inequality x>−3 and x≤2, we graph each inequality. if you use this formula you will be able to get the answer
Answer:
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio, hence
= 4 × = 4 × =
