Answer:
Sarah's reasoning sounds good to start. She rounded the available bags and their content, so the result, 4000 bracelets, should be really easy to reach.
The exact numbers are 214 bags * 22 bracelets / bag = 4708 bracelets; so as you see, Sarah took care of having room to loose some beads and yet the beads will be enough to make 4000 bracelets.
Of course, if you want to be sure, you should ask Sarah some questions. For example:
1) What proportion of beads are normally deffective?
2) What proportion of beads are normally lost when crafting?
So, if Sarah did not take into account those proportions she migth be overestimating the number of bracelets they can make.
Sarah's assumptions of having enough beads for at least 4000 bracelets is correct.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sarah who has 214 bag of beads each bag has enough beads for 22 bracelets
According to Sarah, there are enough beads for at least 4000 bracelets.
Mathematically -
x[e] ≥ 4000
Actual number of beads she could make = 22 x 214 = 4708 = x[a]
Since, x[a] > x[e], we can say that Sarah's assumptions are correct.
Therefore, we can say that Sarah's assumptions are correct.

Answer:
The square roots of 144 are 12 and -12 which are rational numbers.
Step-by-step explanation:
5/3y=-(x-5) the slope intercept
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
[tex]\frac{5}{3}[/tex] y = - (x - 5) ← distribute parenthesis
[tex]\frac{5}{3}[/tex] y = - x + 5 ( multiply through by 3 to clear the fraction )
5y = - 3x + 15 ( divide terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x + 3 ← in slope- intercept form

A line passes through (2, −1) with slope 3. What is the equation of the line in point-slope form?
Hint :- The point slope form of the line is [tex] m(x-x_1) = y - y_1[/tex] , where [tex](x_1,x_2)[/tex] is the point and [tex] m [/tex] is the slope of the line .
Solution :- The given point is [tex](2,-1)[/tex] and the slope is 3 . On using the point slope form of the line, we have ;
[tex]\implies m(x-x_1)=y-y_1[/tex]
Substitute ,
[tex]\implies 3(x -2) = y -(-1) [/tex]
Simplify ,
[tex]\implies 3x -6=y+1 [/tex]
Add -1 and -y to the both sides ,
[tex]\implies \boxed{3x -y -7=0 }[/tex]
Question today susan has 12.6 m ribbon to make flowers if she has to make 4 flowers,how ribbon would use to make 4 flowers
Step-by-step explanation:
3.15m or 3 3/20m
She has a total of 12.6m of ribbbon.
She has to make 4 flowers and each has ribbon.
You take 12.6÷4
Answer:
she would use 3.15 meters on each flower because when you divide 12.6 meters by 4 it equals 3.15 meters.

Agatha drives 73 1/2 miles through two towns in 2 1/3 hours. What is her average speed in miles per hour?
Answer:
31 1/2
Step-by-step explanation:
average speed = distance/time
average speed = (73 1/2 miles)/(2 1/3 hours)
= (147/2 miles)/(7/3 hours)
= 147/2 * 3/7 miles/hour
= 441/14 miles/hour
= 31 1/2 miles/hour

Answer:
Step-by-step explanation:
A truck can be rented from Company A for $140 a day plus $0.30 per mile. Company B charges $80 a day plus $0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
800 miles
Step-by-step explanation:
140 + (0.30 x 800) = 400$, 800 miles
80 + (0.40 x 800) = 400$, 800 miles
(sorry for incorrect answer the first time, mixed up the cost and number of miles)

Mr. Chan places $4000 in a bank as a fixed deposit for 2 years. The bank offers an interest compounded yearly. At the end of 2 years, he receives a total of $4243.60. Find the interest rate.
Answer:
Step-by-step explanation:
Mr. Chan originally placed 4,000 in the bank as a fixed deposit for 2 years.
Each years the bank added a certain amount of interest.
At the end of the 2 years he gained 243 dollars and 60 cents just from interest.
How to solve:
Simply take away the 4 in the amount of money
Leaving: $243.60
( 2 years )
Now divide 243.60 by 1/2
which is 121.8
Mr.Chan got 121.8 worth of interest a year
$10.5 a month
$2.3 a week
6 cents a day
All in 2 years.

What is the measure of the angle
Hey! The measure of the angle is 127
The angle is a total of 180 degrees.
We have to find the total of what's in between the two blue lines.
To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.
