A farmer has bushels to sell at a roadside stand. sells an average of
each day. Represent the total change in the number of bushels for sale after.
The total change in the number of bushels for sale is 64.1 bushels.
Given
A farmer has 160 bushels of apples to sell at her roadside stand. Every day, she sells around a 13 7/10 bushel.
Let us calculate the overall change in the number of bushels she has available for sale after 7 days.
137/10
Now we'll figure out how many bushels she'll sell in seven days.
7 x 137/10
95.9
In 7 days, the farmer will sell 95.9 bushels. To calculate our overall change, subtract this figure from the total number of bushels of apples.
165 - 95.9 = 64.1
Thus, a total of 64.1 bushels have been added to the amount of bushels available for sale.

Is Shape A congruent to Shape B? Explain your reasoning.
Answer:
- Shape A is congruent to Shape B because if you were to rotate one of the two and flip it the would like up and match.
3(2a-b)=a make b the subject of formula
On making b the subject , the formula is b = (5/3)a .
in the question ,
it is given that
the formula is a = 3(2a-b), where the subject is a ,
we have to rewrite the formula with b as the subject .
So, the given formula is
a = 3(2a-b)
simplifying the RHS , we get
a = 3*2a - 3*b
a = 6a - 3b
on re arranging the terms , we get
3b = 6a - a
3b = 5a
Dividing both sides by 3 ,we get
3b/3 = 5a/3
Cancelling out 3 from LHS , we get
b = 5a/3
b = (5/3)a
Therefore , On making b the subject , the formula is b = (5/3)a .

Write the equation of the line in fully simplified slope-intercept form.
Step-by-step explanation:
a slope-intercept form :
y = ax + b
"a" is the slope, "b" is the y-intercept (the y-value when x = 0).
the slope is the ratio (y coordinate change / x coordinate change) when moving from on point on the line to another.
"b" we can read off the graph : when x = 0, then y = -5.
so, b = -5.
for the slope let's pick 2 points. your teacher has kindly marked already points with integer coordinates.
so, I pick (3, 1) and (4, 3).
x changes by +1 (from 3 to 4).
y changes by +2 (from 1 to 3).
so, the slope is
+2/+1 = 2/1 = 2
the equation is
y = 2x - 5
Answer: y=2x-5
Step-by-step explanation:
Choose two points on the graph: (0,-5) and (3,1)
The straight line equation is: y=mx+b
1)
[tex]\displaystyle\\\boxed {The\ slope\ m\ =\frac{y_2-y_1}{x_2-x_1} }[/tex]
[tex]\displaystyle\\x_1=0\ \ \ \ \ x_2=3 \ \ \ \ y_1=-5\ \ \ \ y_2=1\\\\ Hence,\\\\m=\frac{1-(-5)}{3-0} \\\\m=\frac{1+5}{3} \\\\m=\frac{6}{3} \\\\m=2\\\\Thus,\ y=2x+b\ \ \ \ \ (1)[/tex]
2)
To determine the coefficient b, take any of the two points,
for example, (0,-5), that is, x=0 y=5
Substitute these values into formula (1):
[tex]-5=2*0+b\\-5=0+b\\-5=b\\Thus,\ b=-5[/tex]
The result is y=2x-5

the coefficient of x³ in the expansion (2x-1)³
Answer: 8
Step-by-step explanation:
Since the expression is raised to the 3rd power, the highest exponent x will have will be 3. So in order to get the coefficient you multiply 2x by itself 3 times, getting (2x)³ = (2 * 2 * 2)(x * x * x) = (8)(x³) = 8x³

Which 2 expressions are equivalent to 3(x+6)?
1. 3+x+3+x
2. (x+6)+(x+6)+(x+6)
3. 3x+6
4. 3x+18
Answer:
2. (x+6)+(x+6)+(x+6)
4. 3x+18
Why its (x+6)+(x+6)+(x+6)
Since there's a 3 next to (x+6), you are multiplying 3 and (x+6). That means there are three (x+6) groups. Thus, it's just (x+6)+(x+6)+(x+6).
Why its 3x+18
When you use the distributive property, you multiply 3 and x, and multiply 3 and 6, which gives you 3x and 18, which equals 3x+18.

Using it's concept, it is found that:
a) The percent error is of 16.67%.
b) To get the same percent error, the amount of error needs to be the same. Because the estimate was 40 people below the attendance, an estimate of 40 people above the actual attendance will give the same percent error. Therefore, the other estimate that gives the same percent error is an amount of 280 people.
How to find the percent error?
The percent error is given by the difference between the actual and the expected amount, divided by the expected amount and multiplied by 100%.
In the context of this problem, the amounts are given as follows:
Actual amount: 200 people.Expected amount: 240 people.Hence the percent error is given as follows:
(240 - 200)/240 x 100% = 16.67%.
For item b, we want to have the same absolute difference between the actual amount and the expected amount, that is:
|Actual - Expected| = 40.
Meaning that there are two possible outcomes:
Actual - Expected = -40 -> Item a.Actual - Expected = 40 -> Actual = 280.Which gives the answer to item b, completing the sentences.

Step-by-step explanation:
Enter an equation in standard form that models the linear situation. A bathtub that holds 53 gallons of water contains 18 gallons of water. You begin filling it, and after 5 minutes, the tub is full.
The linear equation which represents the situation or the amount of water in the bathtub in terms of the number of minutes is y = 7x + 18.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
Let's suppose the number of minutes by x and the amount of water by y
As per the given question,
The amount of water (y) initially (x = 0) is 18 gallons.
The first point (0,18).
The amount of water (y) at x = 5 is 53 gallons.
The second point (5,53).
The linear equation is given as y = mx + c where m is the slope.
Slope m = (53 - 18)/(5 - 0) = 7
Substitute (0,18) →
18 = 7(0) + c
c = 18
So the equation become as,
y = 7x + 18.
Hence "The linear equation which represents the situation or the amount of water in the bathtub in terms of the number of minutes is y = 7x + 18".

7. What is the cost of a book that was sold for $500 and at a profit of $ 230?
The most appropriate choice for Profit and loss will be given by-
Cost price of the book is $270
What is Profit and loss?
The price at which an article is bought is known as cost price and the price at which the article is sold is known as selling price.
If the selling price of an article is more than the cost price, the difference between the selling price and the cost price gives the profit.
If the selling price of an article is less than the cost price, the difference between the cost price and the selling price gives the loss.
Here,
Selling price of book = $500
Profit = $230
In case of profit, cost price is always less than the selling price
Cost price of the book = Selling price - profit
= $(500 - 230)
= $270

Nathan sells jewelry and earns a 9.75% commission on every piece
he sells. How much commission would he earn on a bracelet that
sold for $220? Use any strategy
Answer:
$21.45
Step-by-step explanation:
You want to know the amount of a 9.75% commission on $220.
CommissionThe amount of the commission is the product of the commission rate and the sales amount to which it is applicable. A 9.75% commission on $220 will be ...
9.75% × $220 = 0.0975 × $220 = $21.45
Nathan would earn a commission of $21.45 on the sale.
__
Additional comment
We know that a 10% commission can be found by moving the decimal point on the sale amount. A 10% commission on $220 will be $22.
The commission rate of 9.75% is 1/4% less than 10%. 1/4% can be found in two steps: find 1%, then find 1/4 of that.
As with 10%, the 1% amount can be found by moving the decimal point. 1% of $220 is $2.20. One-quarter of that will be $2.20/4 = $1.10/2 = $0.55.
This is the amount we must subtract from the 10% value to make it be 9.75%.
The 9.75% commission amount is $22.00 -0.55 = $21.45.

Sarah spent 2 h more travelling by train than she did by bus. The train averaged 70 km/h and the bus 50 km/h. The total distance travelled was 740 km. How far did she travel by bus?
Answer:
250 km
Step-by-step explanation:
Sarah traveled a total of 740 km, 2 hours more at a speed of 70 km/h than at a speed of 50 km/h. You want to know how far she traveled at 50 km/h.
SetupThe relations between time, speed, and distance are ...
distance = speed × time
time = distance/speed
If 'd' represents the distance (km) Sarah traveled by bus (at 50 km/h), then the time (hours) required was ...
time = d/50
The time at 70 km/h is 2 hours more, and the total distance is ...
total distance = (distance at 50 km/h) + (distance at 70 km/h)
740 = d + 70(d/50 +2)
SolutionSimplifying the equation, we have ...
740 = 2.4d +140
600 = 2.4d . . . . . . . . subtract 140
d = 250 . . . . . . . . . . . divide by 2.4
Sarah traveled 250 km by bus.
