Answer:
a(4) = 15/4
Step-by-step explanation:
Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.
Thus, the geometric sequence formula specific to this case is
a(n) = 30(1/:2)^(n-1).
What is the fourth term? Let n = 4,
a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,
a(4) = 15/4.
Answer:
$84.87
Step-by-step explanation:
The mover costs $69
23% of 69 is $15.87
add the two together to get $84.87
(or just multiply 69 by 1.23)
Answer:
This is the value in numbers.
5(n-12)>40
Step-by-step explanation:
Let's solve your inequality step-by-step.
5(n−12)>40
Step 1: Simplify both sides of the inequality.
5n−60>40
Step 2: Add 60 to both sides.
5n−60+60>40+60
5n>100
Step 3: Divide both sides by 5.
5n

Answer:
257 students in the lower school
Step-by-step explanation:
you want to make the fractions have an equal denominator so make 1/3 5/15s and 2/5 to 6/15's, 5+6= 11/15s that leaves 4/15's for the lower part of the school
4 divided by 15 is 4.6 repeating so divide 1200 by 4.66 and boom
Answer:
<h2>y = 3x + b where b is any real number</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equation: 
Parallel lines have the same slope. Therefore the equation of the lines that are parallel to the given line if in form:
where b is any real number.
