7.(WorkPad, must figure out yourself)
8. (essay question, must figure out yourself)
----------->Number 7
y = 4 Since there is no slope,
the input will just be the same as the output
----------->Number 8
a) At the end of 3 years the amount in the account = Principal + Interest
Amount = 4000 + 960 = 4960
Amount at the end of 3 years = $4960
b) Formula for Rate , R = 100I/(PT)
Where I = Interest = 960, P = Principal = 4000, T= Time = 3 years
R = (100 × 960) / ( 4000 × 3)
R = 8
Rate, R = 8% per annum.
c) If the rate was 1% more, R = 8 + 1 = 9% per annum
Interest, I = PRT/100
Interest, I = 4000 × 9 × 3 /100 = 1080
Amount in her account would have been = $4000 + $1080 = $5080
Amount more = $5080 - $4960 = $120
She would have had $120 more should the rate were 1% greater
@Mrs. Elana acting like you're a teacher lol. If you were a teacher you'd know the difference between "your" and "you're".
Cutie pie is 100% correct
1. graph iv
2. b, left side is 25 and right side is 14
3. 105.00
4. b
5. 643.15
6. plan b, 1040.00
7. The graph shows a zero slope since the equation of this graph is y = 4. No matter what the input is, it will just give you the same output. The input doesn't really give a care to the output because the output is just the same all through out.
Thank you Cutie Pie you are the best
could some one plz put the last few questions plz i need them
thanks cutie pie!
why has this been going on sence 2017
What is the rate for number 7??
Interest= Rate*Time
The time is 3 years and the interest is 960$
Is 4,000 the rate?
Can someone please give me some more information so I can figure this out?
-Thanks!
Hello!
I will take the quiz and post the answers for part one and part two!
So, for part one: Math 7 B Unit 3: Patterns and Rules Lesson 7: Compound Interest, the answers are below :)
1. A-- Graph IV
2. B-- Graph goes up, then it's straight, then it goes down
3. D-- $105.00
4. B-- Dots go at an upwards angle starting at one, and go to right above 4
5. C-- $643.15
6. C-- Plan B, $1, 040.00
7. So, this question hasn't been graded yet, but I researched it and used Brainly and I wrote "No matter what input you put into the graph, it will be the same as the output because there is no slope." MAKE SURE YOU CHANGE IT SO YOU DONT CAUGHT! Also, if you don't understand I don't know how to explain so you can google it if you need too :)
I hope this helps you guys, we're almost done with the school year! Stay safe <3
So no one legit knows 7 or 8? I am surprised.
Sometimes people tend to pretend to be someone else in order to make them look ridiculous. Even though some of these users have the name "Mrs. Sue", they can still fake it.
guys I need help with 7 and 8 I you have awsers go to math connexions help
wtf is 7 and 8 tho? and friend me on call of duty w the same @ please.
Math helper thx 🙃
Ms. James jokes on you im using my own device
Again i'm not really sure if I got that right but can someone correct me if i'm wrong?
-Thanks!
is Cutie Pie's answers for Lesson 7 Unit 3 in Mathematics?
So low-key no #7 or #8?? Please help if you know
DOES ANYONE HAVE ALL THE ANSWERS!!!!!!PLEASE!!!!!!!!!
I have 7 quesions?
OwO
They give you the formulas for compound and simple interest, so questions 6,5,4 and 3 should be easy.
Compound: b = p(1+r)to the power "t"
Simple: i = p*r*t
4 years later the answers haven't changed lol
i only have 7 questions
Nobody:
''Ms James'' on her way to tell the principle of the school she *totally works at* and be the hero that nobody asked for nor needed:
🤡

ty cutie pie
TSYM Math helper!!
@*****
the 8th answer is for part 2\
@Happy Hondadays
Okay so with number seven, just put somewhere along the lines of “since there is no slope, the input and the output are the same”!!
Can I get a oowa oowa
@Abby luv
😂😭😭
6 is C not D

DOES ANYONE HAVE THE ANSWERS????!!! PLEASE!!!!!!!!!!!!!
The real Ms. Sue has a name "Ms. Sue", not "Ms sue". Impostors!
If graph essentially goes from lower left to upper right, they increase together.
If graph essentially goes from upper left to lower right, they decrease together.
There are other possibilities to numerous to cover without seeing the graph. for last question idk if its right im sorry if its not idk havent tested it yet
@cutie pie is right, except 6 is D not C.
pog
@Jodan Okay....do you have the FULL answers to number 7 & 8??
lolol tea
this wasn't the real mrs. Sue guys look at the last response. Would a teacher say that? No
wouldn't num 7 be 4,960? at the end of 3 years is earned $960 I know for a FACT that num 3 is C and that num 6 is plan B 1,040.00.
Are you people seriously using this for school? I better tell the principal and make this app banned on the school devices.
1, 2, 4, 8 -- can't see the graph.
3. d - yes
5. b - no
6. c - no
7. Interest = rate times time
960 = 4,000 * r * 3
Because you are here late.
Ohhhh???
Besides, teachers often change the order of questions and answers.
