Answer:
what is the number
Step-by-step explanation:
There are 20 cows and 10 farmers in a field. What is the ratio of the number of ears to the number of legs in the field, and what is the significance of this ratio?
A. 2:3, because two-thirds of those in the field are cows, and they have the greater share of ears and legs
B. 3:5, because for every 3 ears present in the field, there are 5 legs present
C. 2:3, because each farmer has two-thirds the number of ears and legs that a cow has
D. 3:5, because on average, there are 3 ears per individual and 5 legs per individual in the field
B) 3:5
There are more legs on the cows than on the farmers. Even though the amount of ears on both the cows and the farmers are the same it doesn't matter because always have the larger amount of legs.

A contractor purchases 5 dozen pairs of padded work gloves for $67.80. She incorrectly calculates the unit price as $13.56 per pair for the expense report. What is the correct unit price? What is the error?
Answer:
I think the answer would be $1.13 per pair.
Step-by-step explanation:
It states that there were 5 dozen gloves, a dozen equals 12, or in this case 12 pairs. 5 dozen means there would be 5×12=60 or 60 pairs. 67.80÷60(pairs)=1.13 dollars PER pair.
The error is that she divided with the 5 dozens, instead of individual pairs.

The area of a rectangle is 47.44sq.cm. If its length is 16cm, find its breadth?
Need help with this
please
Step-by-step explanation:
Solution,
Area=47.44cm^2
length =16cm
breadth=?
we know,
A=b×h
47.44=16×b
47.44/16=b
2.965cm=b
Therefore b=2.965cm
Answer:
47.44 = 16 x w
47.44÷16= 2.965
width = 2.965

Select all the equations for which (-6, -1) is a solution.
Please note that anyone who answers this post with random letters and or numbers that have nothing to do with this mathematics problem will be deleted or reported.
(Answer A)
y = 4x + 23
(Answer B)
2x + 6y = -6
(Answer C)
2x - 13y = 1
(Answer D)
3x = 1/2y
(Answer E)
3y = 1/2x
If a point is the solution of an equation that it must satisfy the respective equation since y = 4x + 23, 2x - 13y = 1, and 3y = 1/2x satisfy the point (-6,-1) thus option (A),(C) and (E) are correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given point (-6,-1)
Put into y = 4x + 23
-1 = 4(-6) + 23 = -1 so it will be the equation.
Put into 2x - 13y = 1
2(-6) - 13(-1) = 1
-12 + 13 = 1
1 = 1 so it will also equation.
Put into 3y = 1/2x
3(-1) = 1/2(-6)
-3 = -3 so it will also equation.
Hence "If a point is the solution of an equation that it must satisfy the respective equation since y = 4x + 23, 2x - 13y = 1, and 3y = 1/2x satisfy the point (-6,-1)".

The measure of angle JKL in the triangle JKL is 54°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
From the given figure line segments JM and ML are of equal measure as the line segment KM bisects JL and hence bisects the vertex angle.
Therefore,
2x + 5 = 3x - 6.
2x - 3x = - 6 - 5.
- x = - 11.
x = 11.
Now, m∠JKL = 2m∠JKM = 2m∠LKM.
So, m∠JKL = 2[2(11) + 5]°.
= 2(22 + 5)°.
= 2(27)°.
= 54°.

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3
The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.
What is the equation?More than one variable may be present inside a linear equation.
An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
13 = -3 + z
Since, A + B = B + A
Thus, -3 + z can be written as z - 3
So, 13 = z - 3
Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".

Annie is buying new school supplies. She has a budget of $45, and she has already spent $21. She wants to spend the remaining money on notebooks that cost $4 each. What is the greatest number of notebooks, x, Annie can purchase while staying within her budget?
Part A: Write an inequality to represent the situation.
Part B: Solve the inequality. Show all of your work.
Part C: Interpret the solution in terms of the problem.
Answer:
Part A) 45-21 ≥ 4x
Part C) She could buy up to 8 notebooks
Step-by-step explanation:
She already spent $21 so you would need to subtract that from the total budget. The sign would be greater than or equal to since that's the max amount.
45-21 ≥ 34
34≥4x
Divide both sides by 4 to cancel it out. You would get 8.5 but since you can't buy half a notebook it would be 8.

HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!
Answer:
Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%
Answer:
A 4% difference
Step-by-step explanation:
Convert 4 feet 2 into 4.16666666
4/4.16666666= 0.96 or 96%
4 feet was 96% of 4 feet 2 in
100 - 96= 4%
And this shows that there was a 4% error.

1.Lin and her brother each created a scale drawing of their backyard, but at different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard. Whose drawing is larger?
2.How many times larger is Lin's drawing than her brother's drawing? You are being asked to compare the size of the areas of the drawings.
Answer:Part 1) The scale for the drawings without units are 1/12 and 1/36
Part 2) The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36. The explanation in the procedure
Step-by-step explanation:we know that
1) Lin used a scale of
Remember that
1 ft=12 in
substitute in the scale
That means ----> 1 unit in the drawing represent 12 units in the actual
2) Her brother used a scale of
Remember that
1 yd=36 in
substitute in the scale
That means ----> 1 unit in the drawing represent 36 units in the actual
therefore
The scale for the drawings without units are 1/12 and 1/36
Part 2) Whose drawing is larger?
The scale drawing 1/12 is larger than the scale drawing of 1/36
To find out how many times as large is the scale 1/12 than the scale of 1/36
Divide 1/12 by 1/36
The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36
Explanation
Let supposing that we want to represent in the drawing a measure that in its real size measures 36 units.
In the scale of 1/12, the drawing will show a measure of 3 units (remember 3(12)=36 units).
At the 1/36 scale, the drawing will show a measurement of 1 unit (remember 1(36)=36 units).
Therefore the largest drawing will be with a scale of 1/12.
