Jimmy's typing speed is 54 words per minute
Step-by-step explanation:
2/3-----?/60
2(20)/3(20)
40/60 is 2/3 of a minute
36/40 =9/10
9(6)/10(6) = 54/60

answer to question below
Answer:
13n+20
Step-by-step explanation:
Each book costs $13 with a flat rate of $20
You pay $13 for each book, which will be n. And aside from that you also pay for shipping, which will be another $20
So the correct answer is: 13n+20
HELPpppp WITH 6 & 7 pleaseeeeee
number 7 is 21 people
Step-by-step explanation:

Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.
Answer:
$434.16346
Step-by-step explanation:
Given that :
Gross earning= $14500
Federal, state and local taxes = 11%
0.11 * $14500 = $1595
FICA tax rate = 7.65%
0.0765 * 14500 = $1109.25
Personal deduction :
3.5% * 14500
0.035 * 14500 = $507.50
Total deduction :
$(1595 + 1109.25 + 507.50)
= $3211.75
Net earning : $(14500 - 3211.75) = 11288.25
Since she is paid bi weekly:
Number of biweeks in a year = 52 /2 = 26
Number of payments per annum = 26
Hence,
Net pay per period :
11288.25 / 26
= $434.16346
=

I WILL GIVE SOMEONE 40 POINTS TO ANSWER THIS COMPLETELY WITH COLUMS DONE WITH PROBLEMS SOLVED- You are going to design an advertisement for a new polynomial identity that you are going to invent. Your goal for this activity is to demonstrate the proof of your polynomial identity through an algebraic proof and a numerical proof in an engaging way! Make it so the whole world wants to purchase your polynomial identity and can't imagine living without it!
You may do this by making a flier, a newspaper or magazine advertisement, making an infomercial video or audio recording, or designing a visual presentation for investors through a flowchart or PowerPoint.
You must:
Label and display your new polynomial identity
Prove that it is true through an algebraic proof, identifying each step
Demonstrate that your polynomial identity works on numerical relationships
Warning! No identities used in the lesson may be submitted. Create your own using the columns below. See what happens when different binomials or trinomials are combined. Square one factor from column A and add it to one factor from column B to develop your own identity.
Column A Column B
(x − y) (x2 + 2xy + y2)
(x + y) (x2 − 2xy + y2)
(y + x) (ax + b)

The numerical proof is correct! This identity had been proven right in front of your eyes
Algebraic Proof
Amber Carter
Polynomial Identities
So, you want even more proof? Well then lets just substitute in values for a, b, and x. Lets make a=2, b=4, and x=6.
(ax+b) (x+a) = ax^2 +a^2x +bx +ab
(ax+b) (x+a)
+bx +ab
(ax+b) (x+a)=ax^2 +a^2x +bx +ab
This identity is effective and easy to use!
The New Identity
To solve this you have to use the distributive property, more specifically FOIL
Use FOIL on first term
ax^2+a^2x+bx+ab
((2*6)+4) (6+2) = (2^2*6) +(4^2*6) +(2*4)

How much will be in your savings account if you invested $250 at 6.3% interest compounded semiannually after 8 years
Answer:
$664.47
Step-by-step explanation:
A = P(1+i/m)^mn
A = 250(1+0.063/2)^2*8
A = 250(1.063)^16
A = 250*2.657861
A = $664.46525
