This question is incomplete
Complete Question
Joe needs to transfer 28 quarts of oil into gallons containers joe calculated that he needs 112 containers but he made a mistake in his calculations identify and correct his error
Joe's error:
28 quarts × 4 quarts/ 1 gallon
= 28 quarts/1 × 4 quarts/ 1 gallon
= (28 × 4)/ ( 1 × 1) = 112 gallons
Answer:
7 gallons is the correct answer
Joe needs to transfer 28 quarts of oil into 7 gallons
Step-by-step explanation:
Joe's error:
28 quarts × 4 quarts/ 1 gallon
= 28 quarts/1 × 4 quarts/ 1 gallon
= (28 × 4)/ ( 1 × 1) = 112 gallons
Correcting Joe's error, we have:
4 quarts = 1 gallon
28 quarts = x
Cross Multiply
4 quarts × x = 28 quarts × 1 gallon
x = 28 quarts × 1 gallon/ 4 quarts
x = 7 gallons
= 28 quarts/x gallons × 1 gallon/4 quarts
= (28 × x)/ ( 1 /4) = 7 gallons
Therefore, Joe needs to transfer 28 quarts of oil into 7 gallons
Twice a number is equal to negative four. Which equation could be used to find the number?
2n = 4
2n = -4n
2n - 4
2n = -4
Answer:
2n = -4
Step-by-step explanation:
This is because the N is unknown and in the way it's written it means 2 times something is -4
write the equation of a line parallel to the line with an equation y=8x+6 and passes through the point (3,9)
Answer:
y = 8x - 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 8x + 6 ← is in slope- intercept form
with slope m = 8
Parallel lines have equal slopes, thus
y = 8x + c ← is the partial equation
To find c substitute (3, 9) into the partial equation
9 = 24 + c ⇒ c = 9 - 24 = - 15
y = 8x - 15 ← equation of parallel line

Shirley decides to buy a weekly train pass for $25 instead of paying $3.25 each way.
She takes the train to work and back home again for 5 days. How much money does
she save with the weekly pass?
Answer:
75 cents or $0.75
Step-by-step explanation:
1. We see that Shirley takes the train to work and back home. This means she takes the train twice a day. We also see that she uses the train five times a week. So step 1, multiple 5 and 2.
5x2 = 10
2. She pays $25 for a weekly train pass. Divide 25 and 10.
25/10 = 2.5
3. Now, we compare how much money she saved. Subtract 3.25 and 2.5.
3.25-2.5 = 0.75
4. This means she saved 75 cents by purchasing the weekly pass.

Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x = -50 cm and x = +50 cm. The charge densities on the planes are -50 nC/m² and +25 nC/m², respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x = +80 cm? (Hint:Use Gauss’ law.)
Answer:
ΔV = 2520 V
Step-by-step explanation:
We are given;
Charge density 1; σ1 = -50 nC/m² = -50 × 10^(-9) nC/m²
Charge density 2; σ2 = +25 nC/m² = +25 × 10^(-9) nC/m²
Now, formula for electric field strength is;
E = -(½ε)(|σ1| ± |σ2|)
ε is vacuum permittivity with a constant value as 8.85 × 10^(−12) C²/N.m²
|σ1| and |σ2| means we are taking the absolute values and would therefore not use the negative sign attached to them.
Now, in between x = 0 cm(0 m) and 50 cm (0.5 m), electric field generated by both charge densities would be in the same direction and thus;
E_in = -(½ε)(|σ1| + |σ2|)
E_in = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) + (25 × 10^(-9))]
E_in = -4200 V/m
In contrast, when x ≥ 50 cm (0.5 m), electric field generated by both charge densities would be in opposite directions and thus;
E_out = -(½ε)(|σ1| - |σ2|)
E_out = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) - (25 × 10^(-9))]
E_out = 1400 V/m
The magnitude of the potential difference from the origin to x = 80 cm(0.8 m) is calculated as attached;
From the attachment, we see that;
ΔV = 2520 V

Step-by-step explanation:
calculate the sum) 3x-5+x+2(x+2)
distribute 2 through the parentheses) 3x-5=x+2x+4
calculate the like terms) 3x-5=3x+4
calculate equal terms on both sides of the equation) -5 = 4
-5 = 4 meaning that the statement is false!
8. Fred is ordering pies for a family reunion. Each pie costs $4.50. For orders
smaller than a dozen pies, there is a $5 delivery charge. Is the cost proporti
to the number of pies ordered? Use a table of values to explain your reason
Answer:
Yes, because the more pies ordered the more money it will cost to buy them all
Step-by-step explanation:
total cost is not proportional to the number of pies.
What is proportionality?the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
given Fred is ordering pies for a family reunion. Each pie costs $4.50. For orders smaller than a dozen pies, there is a $5 delivery charge.
Fred is ordering pies for a family reunion. Each pie cost $4.50. For orders smaller than a dozen pies, there is a $5 delivery charge.
Let us draw a table for the number of pies and the total cost
Number of pie Total Cost
1 $4.50+5=$9.50
2 $9+5=$14
3 $13.50+5=$18.50
4 $18+5=$230
5 $22.50+5=$26.50
now Total cost/number pies = 9.50/1 is not equals to 14/2
Therefore the total cost is not proportional to the number of pieces

The chess club at school has 15 members. The number of games won in tournament play this season by each other is listed . What measure of the center is most appropriate to use to describe a typical value for the data in the distribution? Explain reasoning .
Answer:
in a example of datas as bellow:
6 6 6 7 10 11 12 13 14 14 15 16 18 18 30
The best method to have the center is by using the Median.
Explanation:
Median is the value that separates the major and minor half of a sample, population or probability distribution. In simpler terms, median can be the middle value of a data set. In the data set {1, 3, 3, 6, 7, 8, 9}, for example, the median is 6. If there is an even number of observations, there is not a single middle value.

The function f(t)=|98.6-x|, represents a persons variance from normal body temperature, where x represents a persons current body temperature in degrees Fahrenheit. Medical professionals says healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit
Answer:
Step-by-step explanation:
Given the various variance of normal body temperature expressed by the function f(t) = |98.6-x| where x is persons current body temperature in degree Fahrenheit.
If medical professional says that healthy individual cannot have a variance of no more than 0.5F, we can get the variance by substituting x = 0.5 into the modeled function as shown;
Note that the function can either be negative or positive because of the modulus sign
If x = 0.5
For positive value,
f(0.5) = 98.6-0.5
f(0.5) = 98.1
If the function is negative
f(0.5) = -(98.6-0.5)
f(0.5) = -98.6+0.5
f(0.5) = -98.1
The variance for healthy individual will be expressed as -98.1≤f(x)≤98.1

Which graph best represents the equation y=2x+5?
Answer:
B?
Step-by-step explanation:
The graph y = 2x + 5 can be represented by the image attached below.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Given, An equation y = 2x + 5, we can graph this by assuming some arbitrary values of 'x' that correspond to some arbitrary values of 'y'.
When x = 0, y = 5.
x = 1, y = 7 ⇒ (1, 7).
x = 5, y = 15 ⇒ (5, 15).
x = - 5, y = - 5 ⇒ (- 5, - 5).
x = - 2, y = 1 ⇒ (- 2, 1).

Riley agreed to a payment plan for the refrigerator. She used a graph to record her payments and the remaining balance. Which two statements are true about the graph?
Answer:
Step-by-step explanation:
Its the first option and the third.
The true statements are,
Riley's made larger than normal payment in month 11Riley paid the entire balance after one year and eight months of paymentsWhat are intercepts?The x-intercept is the point where a line crosses the x-axis, and y-intercept is the point where the line crosses the y-axis.
Now from the graph, following information are extracted-
Now Riley's made larger than normal payment in month
At 0 month, amount is $1,050
At 1 month, amount is $1,050
At 2 month, amount is $975
At 3 month, amount is $875
.
,
At 10 month, amount is $525
At 11 month, amount is $425
At 12 month, amount is $375
.
.
At 18 month, amount is $325
At 20 month, amount is $0
Thus, from the above Riley's made larger than normal payment in month 11
The intercept of month becomes 0 at 20 months.
Thus, Riley paid the entire balance after twenty months of payments
Therefore, Riley paid the entire balance after one year and eight months of payments.
Thus, the true statements are,
Riley's made larger than normal payment in month 11Riley paid the entire balance after one year and eight months of paymentsTo learn more about graphs :
