Answer:
6, 9, 12, 15
Step-by-step explanation:
Comparing the given formula to the formula for the general term of an arithmetic sequence, ...
an = a1 +d(n -1)
we see that a1 = 6 and d = 3. That is, the first term of the sequence is 6 and each term is 3 more than the last.
The first 4 terms are 6, 9, 12, 15.
Answer:
(a)
perimeter = 2 + 8 + 4 + 7x + 4x
(b)
perimeter = 11x + 14
Problem 3
Circumference = pi*diameter
C = pi*d
C = 3.14*7.6
C = 23.864
C = 23.9
<h3>Answer: 23.9 cm</h3>
=======================================
Problem 4
A = area of square
A = side*side
A = 8*8
A = 64 square cm
B = area of circle
B = pi*r^2
B = 3.14*(5.5)^2 .... radius = 5.5 is half of diameter = 11
B = 94.985
C = area of shaded region
C = B - A
C = 94.985 - 64
C = 30.985
<h3>Answer: 30.985 square cm</h3>
=======================================
Problem 5
diameter = 6
radius = 3
area = pi*radius^2
A = pi*r^2
A = pi*3^2
A = 9*pi
A = 9*3.14
A = 28.26
<h3>Answer: 28.26 square millimeters</h3>
Answer:
The first and third options are valid.
Step-by-step explanation:
If two of the three sides of a right triangle are 5 inches and 4 inches, then we have to select the equation from options that can be used to find the unknown length b, in the triangle.
The first equation 4² + b² = 5² can be the possible equation.
The second equation 4² - b² = 5², ⇒ 4² = b² + 5² can not be the equation as 4 being the hypotenuse should be the largest side but 4 < 5.
The third equation 5² + 4² = b² can be the possible equation.
The fourth equation 5² + b² = 4² is similar to the second equation. So, it is not possible.
Therefore, the first and third options are valid. (Answer)
There are 52 weeks in a year so divide 39,000 by 52 to find out weekly pay(750) then multiply that by 2 to find biweekly pay (1,500)
Answer: Jonathon gets paid $1,500 biweekly
