ALGEBRA Michella Hong noticed that her gross pay per period increased by $2,800 when her employer changed from a bi-weekly pay plan to a monthly pay plan. What is Michelle's annual salary
Answer:
Her annual salary is $62,400
Step-by-step explanation:
Michelle Hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a monthly pay plan.
Bi weekly is a check every 2 weeks, so she would get 26 checks per year.
Monthly would be 12 checks per year.
When she gets paid monthly her pay increased by $2,800 each check.
Let x be one bi-weekly paycheck.
The equation we get is:
12(x+2800) = 26x
Multiply the bracket by 12:
12x +33600 = 26x
Subtract 12x from both sides
33600 = 14x
Divide both sides by 14:
x = 33600/14
x = 2400
Her pay increased by 2800 each period:
2400 + 2800 = 5200 per check.
5200 x 12 months = 62400
Her annual salary is $62,400
The volume for a rectangular prism is given by the formula V = l · w · h, where l is the length of the prism, w is the width of the prism, and h is the height of the prism.
If the volume of a rectangular prism with a length and width of 3 inches is 81 cubic inches, what is the height of the rectangular prism?
A.
9 inches
B.
75 inches
C.
14 inches
D.
27 inches
Answer: It is A, or 9 inches
Step-by-step explanation:
1. We know that the length and width is 3, so that is 3 * 3, which is 9
2. Therefore, with the volume of 81, we would know that 9 * 9 is 81, so the height is 9 inches
The volume of the given right circular cylinder is 256π cubic yards. If h, the height of the cylinder is 16 yards, what is r, the radius of the base?

Write an equation in slope-intercept form for the perpendicular bisector of the segment with the given endpoints. Justify your answer. (Lesson 5-1)
D(-2,-4) and E(2,1)
The equation of the perpendicular bisector of the segment with the endpoints located at D(-2 ,-4) and E(2 , 1) is y = -4/5x - 3/2.
A perpendicular bisector of a segment is a line that divides the segment into two equal parts forming right angles at the point of intersection.
To get the perpendicular bisector of a segment, get the point of intersection of the two lines which is the midpoint of the segment.
midpoint (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]
midpoint (x , y) = [(-2 + 2)/2 , (-4 + 1)/2]
midpoint (x , y) = (0 , -3/2)
Get the slope of the perpendicular bisector of a segment by taking the negative reciprocal of the slope of the segment.
slope of segment = (y2 - y1)/(x2 - x1)
slope of segment = (1 - -4)/(2 - -2)
slope of segment = 5/4
slope of the perpendicular bisector = -4/5
Solving for the y-intercept, b, plug in the point (0 , -3/2) and the slope -4/5 to the slope-intercept form of the equation, y = mx + b.
y = mx + b
-3/2 = -4/5(0) + b
b = -3/2
Setting up the equation in slope-intercept form, where m = -4/5 and b = -3/2.
y = mx + b
y = -4/5x - 3/2

To jump at a local trampoline park, each attendee is charged $14.75 per hour. In addition, each attendee must spend $3.50 to purchase a pair of jumping socks. The trampoline park also offers food specials. Currently, attendees can purchase a super pizza deal, which includes a large pizza and a pitcher of soda, for only $15.50 . Five friends decide to visit the trampoline park. Each friend will buy a pair of socks and jump for two hours. The friends will also buy one super pizza deal to share.
Answer:
Step-by-step explanation:
(14.75x10)+(3.5x5)+15.50= 180.5
14.75= trampoline per hour
10= the friends 2x hours
3.5= socks
5= the number of friends

Write a conjecture that describes the pattern in the sequence. Then use your conjecture to find the next item in the sequence. 0,2,4,6,8
The conjecture that describes the pattern in the sequence is current term is 2 added to the previous term and the next term is 10
How to write a conjecture that describes the pattern in the sequence?The sequence is given as:
0, 2, 4, 6, 8
In the above sequence, we can see that each current term is 2 added to the previous term
i.e.
Tn = 2 + Tn-1
Using the above conjecture, we have
Next term = 8 + 2
Evaluate
Next term = 10
Hence, the conjecture that describes the pattern in the sequence is current term is 2 added to the previous term and the next term is 10

Find the zero(s) of f(x) = -4x + 6
The zero(s) of function f(x) = -4x + 6 is [tex]x=\frac{3}{2}[/tex]
As per the question statement, We are given a function [tex]f(x) = -4x + 6[/tex] and we are supposed to find the zero(s) of the function.
We know that zero of a function is the value of the function at which the value of function becomes absolute zero.
For that we have to equate the function to zero first.
f(x) indicates the function with variable in "x"
For zero(s), of f(x)
Let f(x) = 0

how to multiply a fraction(s)?
Fractions Context: How do they work? -
- In every fraction, there's a top number and a bottom number, separated by a short horizontal line.
- In a proper fraction, the smaller number — called the numerator — will always be on top, while the larger number — the denominator — will be on the bottom.
(NOTE: The larger number is not always on the bottom, when it's on the top it is considered an improper fraction!)
- The numerator tells us how many units we have of a whole and the denominator tells us how many units make up the whole. So, in the fraction 1/2, 1 is the numerator and 2 is the denominator — there are two units in the whole, but this fraction tells us that we only have one of these units.

A person is $1000 on the credit card that charges an interest rate of 2% per month complete the table showing the car to balance each month if you do not make any payments
Answer:
Month Total Bill
1 1000
2 1,020
3 1,040.40
4 1,061.21
5 1,082.43
6 1,104.08
7 1,126.16
8 1,148.69
Step-by-step explanation:
Use the formula for compound interest
[tex]A = P(1+r)^t[/tex]
where A is the balance, P is the principal (credit card balance), r is the effective rate and t is the number of time periods
Here r = 2% computed monthly which is 2/100 = 0.02 in decimal and t = 1, 2,3,4,5,6,7,8 months
So 1 + r = 1+0.02 = 1.02
We can compute the monthly balance for each subsequent month by multiplying the previous month's balance by 1.02
All figures rounded to the nearest cent
Answer
Month Total Bill
1 1000
2 1,000 x 1.02 = 1,020
3 1,020 x 1.02 = 1,040.40
4 1,040.40 x 1.02 = 1,061.21
5 1,061.21 x 1.02 = 1,082.43
6 1,082.43 x 1.02 = 1,104.08
7 1,104.08 x 1.02 = 1,126.16
8 1,126.16 x 1.02 = 1,148.69
