Jessie estimated the weight of his cat to be 12 pounds. The actual weight of the cat is 15 pounds.
What is the percent error?
Round your answer to the nearest whole percent.
Answers
Answer:
20%
Step-by-step explanation:
% of error is given by the following formula:
% Error = [tex]\frac{|\textrm {Approx Value - Exact Value}|}{\textrm {Exact Value}} \times 100[/tex]
Now, Jessie estimated the weight of his cat to be 12 pounds i.e. Approximate value is 12 pounds.
Again, The actual weight of the cat is 15 pounds i.e. the exact value is 15 pounds.
Therefore, the % error = [tex]\frac{|12 - 15|}{15} \times 100 = \frac{3}{15} \times 100 = 20[/tex]% (Answer)

A gardener at a nursery is filling pots with soil to prepare to
transplant seedlings into these larger pots. Each new pot needs about 27 cubic inches
of soil. The amount of soil s (in cubic inches) it takes to fill p pots is given by the
function s = 27p
a.
The gardener is filling the pots from a bag of soil that contains 3456 cubic
inches of soil. How many pots can be filled from the bag?
b.
Suppose the gardener needs to fill at most 109 pots. How much soil (in cubic
inches) will the gardener need?
Answers
Answer:
a. 127 pots
b. 2,943 cubic inches
Step-by-step explanation:
To find the amount of pots of soil can be filled, you can use the equation given. s = 3456 in part a
a.
s = 27p
3456 = 27p
divide 3456 by 27 to isolate p
p = 127 pots
Instead of substituting for s like in part a, you can now substitute for p, since you know that you need to fill 109 pots.
b.
s = 27 * 109
s = 2943 cubic inches
The gardener can fill 128 pots with the 3456 cubic inches of soil available. If the gardener needs to fill at most 109 pots, they will require 2943 cubic inches of soil.
To solve both parts of the question, we will use the function s = 27p, where s represents the amount of soil (in cubic inches) and p represents the number of pots.
Part a: Calculating the Number of Pots
The gardener has a bag containing 3456 cubic inches of soil. To find out how many pots can be filled from the bag, we need to divide the total amount of soil by the amount needed per pot:
p = 3456 cubic inches / 27 cubic inches per pot = 128 pots
Part b: Soil Needed for a Maximum Number of Pots
If the gardener needs to fill at most 109 pots, the total amount of soil required can be calculated using the provided function:
s = 27 cubic inches per pot * 109 pots = 2943 cubic inches of soil

A piece of cloth costs 200$.if the piece was 5m longer, and the cost of each metre of clth was 2$ less, the cost of the piece would have remained unchanged. How long is the piece and what is its original number of persons.
Answers
Answer:
20 m long,
each piece of cloth for $10
Step-by-step explanation:
Let x m be the length of the piece of cloth.
Original cloth:
Length = x m
Cost = $200
Cost per meter [tex]\dfrac{\$200}{x}[/tex]
Changed cloth:
Length = x + 5 m (5 m longer)
Cost = $200
Cost per meter [tex]\dfrac{\$200}{x}-\$2[/tex] (each metre of cloth was $2 less)
Hence,
[tex]\left(\dfrac{200}{x}-2\right)\cdot (x+5)=200[/tex]
Multiply the equation by x:
[tex](200-2x)(x+5)=200x\\ \\200x+1,000-2x^2-10x=200x\\ \\-2x^2-10x+1,000=0\\ \\x^2+5x-500=0\\ \\D=5^2-4\cdot(-500)=25+2,000=2,025\\ \\x_{1,2}=\dfrac{-5\pm\sqrt{2,025}}{2}=\dfrac{-5\pm 45}{2}=-25,\ 20[/tex]
The length cannot be negative, so x = 20 m, each metre for $10.
Answer:
The piece is 20 m long and costs $10 per meter
Step-by-step explanation:
The total cost of the cloth in $ can be expressed as
C = xu
Where x is the length of the cloth in m, and u is the unit cost in $/m
The problem states that if the length was 5 meters more and the unit cost was $2 less, the cost would not change, that is
C = (x+5)(u-2)
Operating:
C = xu-2x+5u-10
Since C = xu, then
-2x+5u=10 [1]
We also know that
xu=200 [2]
Isolating u in [1] we get
[tex]u=\frac{10+2x}{5}[/tex]
Replacing into [2]
[tex]x\frac{10+2x}{5}=200[/tex]
Simplifying
[tex]10x+2x^2=1000 \\=> x^2+5x-500=0[/tex]
Factoring
(x-20)(x+25)=0
Which gives x=20, x=-25. We can only use the positive value of x, so
x=20 m and therefore
u=200/20=10$
So the piece is 20 m long and costs $10 per meter

105
Step-by-step explanation:
Theorem:
If parallel lines are cut by a transversal, then same-side interior angles are supplementary.
Lines AB and CD are parallel, and angles 3 and 6 are same-side interior angles, so by the theorem above, angles 3 and 6 are supplementary. That means that the sum of their measures is 180 deg.
m<3 + m<6 = 180
m<3 + 75 = 180
Subtract 75 from both sides.

What is the equation of the line that is parallel to the line 2x+3y=-8 and passes through the point (2,-2)?
Answers
Equation of line passing through (2, -2) and parallel to 2x+3y = -8 is [tex]y=\frac{-2 x}{3}+\frac{-2}{3}[/tex]
Solution:Need to write equation of line parallel to 2x+3y=-8 and passes through the point (2, -2)
Generic slope intercept form of a line is given by y = mx + c
where "m" = slope of the line and "c" is the y - intercept
Let’s first find slope intercept form of 2x+3y=-8 to get slope of line
[tex]\begin{array}{l}{2 x+3 y=-8} \\\\ {=>y=\frac{-2 x-8}{3}} \\\\ {\Rightarrow y=-\frac{2}{3} x-\frac{8}{3}}\end{array}[/tex]
On comparing above slope intercept form of given equation with generic slope intercept form y = mx + c,
[tex]\text {for line } 2 x+3 y=-8, \text { slope } m=-\frac{2}{3}[/tex]
We know that slopes of parallel lines are always equal
So the slope of line passing through (2, -2) is also [tex]m=-\frac{2}{3}[/tex]
Equation of line passing through [tex](x_1 , y_1)[/tex] and having slope of m is given by
[tex]\left(y-y_{1}\right)=\mathrm{m}\left(x-x_{1}\right)[/tex]
[tex]\text { In our case } x_{1}=2 \text { and } y_{1}=-2[/tex]
Substituting the values in equation of line we get
[tex](y-(-2))=-\frac{2}{3}(x-2)[/tex]
[tex]\begin{array}{l}{\Rightarrow y+2=\frac{-2 x+4}{3}} \\\\ {=>3(y+2)=-2 x+4} \\\\ {=>3 y+6=-2 x+4} \\\\ {3 y=-2 x-2}\end{array}[/tex]
[tex]y=\frac{-2 x}{3}+\frac{-2}{3}[/tex]
Hence equation of line passing through (2 , -2) and parallel to 2x + 3y = -8 is given as [tex]y=\frac{-2 x}{3}+\frac{-2}{3}[/tex]

we know ∠STR+∠STU=180
x+20=180
x=160
2. By external angle property
x+24=105

3. By Angle Sum Property
∠ 1=∠2=∠3=∠4=90
and
∠5=∠6=∠7=∠8=90
Hence all angles are equal to 90
and we know only parallel lines have
∠4=∠5
∠3=∠6
hence line 'r' and line 't' are parallel.
4. For being parallel side pieces must not form a triangle(i.e. sum two interior angle must be equal to 180)

The sum of two numbers is 53 and the difference is 27. What are the numbers?
Answers
Final answer:
The two numbers are 40 and 13.
Explanation:
We are given that the sum of two numbers is 53, and their difference is 27. Let's denote the two unknown numbers as x and y, where x is the larger number.
The system of equations based on the given information is:
x + y = 53x - y = 27By adding the two equations, the y's cancel out:
(x + y) + (x - y) = 53 + 272x = 80x = 40Now, we can find the value of y by substituting x into the first equation:
40 + y = 53y = 53 - 40y = 13The two numbers are 40 and 13.

What is the slope of a line that contains
the point (-0.5, 4) and has a y-intercept
of -5?
Answers
Answer:
The slope of line that contain the points ( - 0.5 , 4 ) and has y- intercept of - 5 is -18
Step-by-step explanation:
Given as :
The points that satisfy the line is ( - 0.5 , 4 )
The y - intercept = - 5
The equation of line is
y = m x + c
Where m is the slope of line
∵ For y- intercept , c = - 5
Now, points on the line is ( - 0.5 , 4 ) and y intercept c = - 5 is
y = m x + c
or, 4 = m × ( - 0. 5 ) + ( - 5 )
Or, 4 = - 0. 5 m - 5
or, 4 + 5 = - 0.5 m
Or, 9 = - 0. 5 m
∴ m = [tex]\frac{-9}{0.5}[/tex]
So, Slope = m = - 18
Hence the slope of line that contain the points ( - 0.5 , 4 ) and has y- intercept of - 5 is -18 Answer
Final answer:
The slope of a line that contains the point (-0.5, 4) and has a y-intercept of -5 is -18. This is calculated using the slope formula, resulting in a negative slope.
Explanation:
To find the slope of a line with a given point and a y-intercept, we can use the slope formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) is the given point and (x2, y2) is the y-intercept point. Since the y-intercept is at a point where x = 0, the second point is (0, -5).
The given point is (-0.5, 4), so after substituting into the slope formula we get: slope = (-5 - 4) / (0 - (-0.5)) = (-9) / (0.5) = -18. The slope of the line is -18, indicating a negative slope meaning the line will move downwards on the graph as the x-value increases.

The n - 1 is even.
Note that the product of odd and even is always even. That is the product of n and (n - 1) is even.
Case II:
when 'n' is even
Then n - 1 is odd.
Again, using the similar logic we can say that the product of n and n - 1 should be even because here, 'n - 1' is even and 'n' is odd.
57 first-year teachers and 19 experienced teachers attended a school staff meeting meeting. What percentage of the teachers in the meeting were first-year teachers?
Write your answer using a percent sign (%).
Answers
Answer:
75%
Step-by-step explanation:
57 / (57+19) = 0.75
Final answer:
About 75% of the teachers in the meeting were first-year teachers, as calculated by dividing the number of first-year teachers by the total number of teachers and then multiplying by 100.
Explanation:
To determine what percentage of the teachers in the meeting were first-year teachers, we use the formula 'part over total, times one hundred, equals percent'. In this scenario, the 'part' is the number of first-year teachers which is 57, and the 'total' is the sum of first-year and experienced teachers, which is 57 + 19 = 76. The calculation then becomes 57/76 times 100, to find that percentage.
Carrying out the calculation:
(57 / 76) times 100 = 0.75 times 100 = 75%
Therefore, approximately 75% of the teachers at the meeting were first-year teachers.
