The steps Quentin took to evaluate the expression 3m - 3+3 when m = 8
are shown below.
3m - 3 + 3 when m=8
3 x 8 = 24
24 - 3 =21
21 + 3 = 7
What should Quentin have done differently in order to evaluate the
expression?
divided (24-3) by (24x3)
divided (24-3) by (24-3)
subtracted (3 + 3) from 24
subtracted 3 from (24 +3)
Quentin had properly substituted m with 8, but he mistakenly added 3 to 21 rather than subtracting. The right final calculation should provide 24, not 7.
Explanation:In order to correctly evaluate the expression 3m - 3 + 3 when m = 8, Quentin starts off correctly by replacing m with 8, resulting in 24. The mistake happens when Quentin incorrectly adds 3 to 21 instead of subtracting 3 from 21. The correct sequence of steps should be:
3m - 3 + 3 when m=8Replace m with 8. Therefore, 3 * 8 = 24Subtract 3 from 24. Therefore, 24 - 3 = 21Add 3 back to the result of 21 - 3. Therefore, 21 + 3 = 24Learn more about Math Expression Error Correction here:

How to define a transformation?
Here we have a transformation that enlarges and rotates our original rectangle, with vertices M, N, O, and P.
Transformations do not act only on figures, they act on every point on the plane, so we could apply the same transformation to each one of the vertices, in such a way, we will get:
M → M'N → N'O → O'P → P'.Writing all of these together, we just get:
MNOP → M'N'O'P'

Find the area of the circle below
You can find the area of a circle by using this formula:
[tex]y = \pi r^2[/tex]
Knowing that a circle's diameter is double its radius, we know that the radius of this circle is 12.5 yards. Substitute this for r in the equation to find the area:
[tex]y = \pi *12.5^2\\y=156.25*\pi \\y=490.87[/tex]
Answer:
The area of the circle is 490.8738521 yards or if your rounding 490.87 yards.
Step-by-step explanation:
Area of circle = πr²
r = half of diameter
r = 25 ÷ 2
r = 12.5
A = π(12.5)²
A = π(156.25)
A = 490.8738521
A ≈ 490.87 yards

Estimate the perimeter of the figure to the nearest whole number.
Answer:
See Explanation Below
Step-by-step explanation:
The question is incomplete (because the figure to calculate the perimeter is missing).
However from the comment attached to your question, I understand that the figure looks like a plus sign.
The perimeter of a plane shape is calculated by adding the length of each side of the shape.
Take for instance;
A square of length 5cm.
We know that a square has 4 equal sides; meaning that the length of the other sides are also 5cm
So, the perimeter of the square will be calculated as 5cm + 5cm + 5cm + 5cm = 20cm
Similarly, the perimeter of a triangle whose sides are 4ft, 3ft and 5ft will be calculated by adding up the length of the three sides.
Perimeter of the triangle = 4ft + 3ft + 5ft
Perimeter = 12ft.
Having explained how the perimeter of a plane shape is calculated; take for example, the attachment below.
(The sides are measured in centimetres)
The plus sign has 12 sides; Its perimeter is calculated by adding up the length of the 12 sides.
Perimeter = 3 + 7 + 7 + 5 + 5 + 5 + 5 + 2 + 2 + 4 + 4 + 3
Perimeter = 52cm

The Deep Creek State Forest is a 380-acre state forest located 11 miles north of St. Augustine, Florida. The cottontail rabbit population in this forest grows at the rate of 5% monthly. If there are 175 rabbits in forest in September, find how many rabbits should be expected by next September. Use the formula: y=175(2.7)0.05t y = 175 ( 2 . 7 ) 0 . 05 t . Round your answer to the nearest whole number. The cottontail rabbit population next September is expected to be rabbits. (Round your answer to the nearest whole number)
Answer:
By next September, the estimated population would be 284 cottontail rabbits
Step-by-step explanation:
The formula that express the growth of the rabbits is
Y = 175(2.7)0.05t
Y = number of rabbits
Where t = time in months.
The growth of the rabbits in 12 months would be. Since from one September to another equal 1 year which is 12 months.
Y = 175(2.7)0.05(12)
Y = 283.5 = 284 rabbits
The estimated population of cottontail rabbits by next September is 284 rabbits

Rewrite as a simplified fraction.
0.2 = ?
Answer:
1/5
Step-by-step explanation:
When changing a decimal to a fraction, think of the decimal "out of 1." In mathematical terms, "out of" generally means division.
For example on this question, think of 0.2 as 0.2 out of 1, which would be shown as 0.2/1
To more easily simplify this, multiply both the top and bottom by 10
0.2/1 x 10/10
You are able to do this because 10/10 is equal to 1 and multiplying by a number and 1 results in the same number.
Then you get 2 /10 . Both 2 and 10 are divisible by 2
2 /2 = 1 and 10 /2 = 5
So the final answer is 1/5

Dante bought a new graduated cylinder for his chemistry class. It holds 662.7 milliliters of liquid. If the cylinder has a radius of 4.7 cm, then how tall is the cylinder? (Note: 1 milliliter is equal to 1 cubic centimeter)
A.
141 cm
B.
19,881 cm
C.
30 cm
D.
70.5 cm
Given:
Dante bought a new graduated cylinder for his chemistry class.
Volume of the cylinder = 662.7π milliliters of liquid
Converting to cubic centimeter, we get;
Volume of the cylinder = 662.7π cm³
Radius of the cylinder = 4.7 cm
We need to determine the height of the cylinder.
Height of the cylinder:
The height of the cylinder can be determined using the formula,
[tex]V=\pi r^2 h[/tex]
Substituting the values, we have;
[tex]662.7 \pi=\pi (4.7)^2h[/tex]
[tex]662.7 \pi=\pi (22.09)h[/tex]
Dividing both sides by 22.09π, we get;
[tex]30=h[/tex]
Therefore, the height of the cylinder is 30 cm.
Hence, Option C is the correct answer.
The calculated height of the graduated cylinder is approximately 30 cm, which is option C.
To determine how tall Dante's graduated cylinder is, given it holds 662.7π milliliters (mL) of liquid, we should use the formula for the volume of a cylinder, V = πr²h, where 'V' is the volume, 'r' is the radius, and 'h' is the height.
Since 1 milliliter is equivalent to 1 cubic centimeter (cm³), we have V = 662.7π cm³, and the radius 'r' is given as 4.7 cm. Inserting these values into the formula and solving for 'h' gives us:
V = πr²h
662.7π cm³ = π × (4.7 cm)² × h
662.7π cm³ = π × (22.09 cm²) × h
662.7π cm³ = 22.09π × h
h = 662.7 cm³ /22.09
h ≈ 30cm
Therefore, the height of the cylinder is approximately option c. 30 cm.
The above question is incomplete, the complete question is:

How many inches if wooden sticks will be required?
The required amount of wooden sticks would depend on specific measurements for different projects, such as making a Biltmore stick for tree height measurement or spacing vertical studs 16 inches apart, which is equal to 40.64 centimeters. Measurements and conversions would be necessary to determine the exact amount of material needed.
Explanation:The amount of wooden sticks required would depend on the specific project being undertaken. The details provided mention various projects, including constructing a Biltmore stick for measuring tree heights, vertical studs spaced 16 inches apart for lumber usage, and spacing between scaffolds that could be anywhere from 3 to 12 inches. For the Biltmore stick, you would need a stick long enough to reach from your eye level to the ground, as well as additional sticks or markers for the grading. For constructing vertical studs spaced 16 inches apart, you would convert that distance into centimeters, where 16 inches is equal to about 40.64 centimeters. Other examples require sticks of varying sizes, from the barrel of a plastic stick pen cut in half, which would be a few inches, to a list of materials needed for a pyramid structure that changes by 12 inches per level.

If a triangle has one angle that measures 62.5o and another angle that measures 77o , then what is the measurement of the last angle?
Answer:
40.5 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees, so to solve this all you need to do is add the two numbers you have and subtract them from 180.
62.5+77+x=180
139.5+x=180
-139.5 -139.5
x=40.5
To find the measurement of the last angle in a triangle, subtract the sum of the known angle measurements from 180 degrees. Given angles of 62.5° and 77°, the measurement of the last angle is 40.5°.
The question involves finding the measurement of the last angle in a triangle given the measurements of the other two angles. In Euclidean geometry, it is established that the sum of the angles in a triangle equals 180 degrees. Given that one angle measures 62.5° and another measures 77°, we can find the last angle by subtracting the sum of these two angles from 180 degrees.
Step 1: Add the measurements of the two known angles: 62.5° + 77° = 139.5°.
Step 2: Subtract this sum from 180°: 180° - 139.5° = 40.5°.
Therefore, the measurement of the last angle in the triangle is 40.5°.
