Answer:
The superlative degree compares more than two things to show which has the least or greatest degree of the quality.comparative degree is used when just comparing two things.
Step-by-step explanation:
Final answer:
The comparative degree is used to compare two items, while the superlative degree is used to compare three or more. Comparatives typically end in -er, while superlatives end in -est, except in cases of adjectives with more syllables where 'more' and 'most' are used respectively. Absolute adjectives generally do not have comparative or superlative forms.
Explanation:
Difference Between the Comparative and Superlative Degree
The comparative and superlative degrees are used to make comparisons between nouns based on some attributes described by adjectives or adverbs. The comparative degree is used when comparing two items, while the superlative degree is used when comparing three or more items. Comparative adjectives often end in -er, and superlative adjectives often end in -est. For example, the adjective 'hot' becomes 'hotter' in the comparative form and 'hottest' in the superlative form.
For adjectives of three or more syllables, and some two-syllable adjectives, the comparative is formed by adding the word 'more' before the adjective, and the superlative is formed with 'most'. For instance, 'famous' becomes 'more famous' and 'most famous' in comparative and superlative forms respectively. Some adjectives and adverbs are irregular and do not follow these standard patterns of formation. Furthermore, adjectives that describe absolute qualities, such as 'dead' or 'pregnant', typically do not have comparative or superlative forms.
It is important to never use both types of comparison for the same adjective, as in 'most hardest'. The correct form would be 'hardest', without the 'most'. Also, it's useful to know that adjectives imply a scale of degrees, and comparative forms indicate one item's position on that scale in relation to another, while superlatives indicate the extreme ends of that scale.

Topic: Volume
Answer:
V = 77 m^3
Step-by-step explanation:
We want the volume of the cylinder
V = pi r^2 h
We know the diameter not the radius
r = d/2 = 7/2 = 3.5
V = 3.14 * (3.5)^2 (2)
V = 76.93 m^3
To the nearest cubic meter
V = 77 m^3
The answer is 77 m^3
Quick question though... Why say "easy" and ask for an answer?
A cylinder has a base diameter of 10m and a height of 14m. What is its volume in cubic m, to the nearest tenths place?
Answer:
1099.6 m³
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h. In this case, the radius, r, is half the diameter, 10 m: r = 5 m, and the height is 14 m.
Thus, the volume of this cylinder is
V = π(5 m)²(14 m) = 1099.6 m³ (to the nearest tenths place).
The volume of the cylinder is approximately 1099.6 cubic meters to the nearest tenth place.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
The formula for the volume of a cylinder is:
V = πr²h
where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14159).
To find the radius of the cylinder, we need to divide the diameter by 2:
r = d/2 = 10m / 2 = 5m
Now we can plug in the values:
V = πr²h = π(5m)²(14m) = 350π m³
To approximate the value to the nearest tenths place, we can substitute the value of π as 3.14159 and use a calculator to evaluate the expression:
V ≈ 350 × 3.14159 ≈ 1099.56 ≈ 1099.6
Therefore, the volume is 1099.6 cubic meters.

Mike bought 7 new baseball cards to add to his collection. The next day his dog ate half of his collection. There are now only 41 cards left. How many cards did Mike start with?
Answer: Mike started with 75 cards
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The number of cards mike started with (x) plus the new cards added (7) must be divided by 2 (since his dog ate half of his collection).
That expression must be equal to the number of cards left (41)
Mathematically speaking:
(x + 7) /2 = 41
Solving for x:
x+7 = 41x2
x+7 = 82
x = 82-7
x = 75 cards

Answer:
438.86
Step-by-step explanation:
1. 457 x 0.99 = 452.43 - Decreased by 1%
2. We need to decrease 452.43 again but this time by 3% - 452.43 x 0.97
3. This gives us an answer of 438.8571
4. Finally we need to round this to 2DP, the 7 (438.8571) rounds up so the number to the left increases. This leaves an answer of 438.86

find the x and the area of the shape perimeter is 64.5
Answer:
x=8
A = 192
Step-by-step explanation:
The perimeter is the sum of the outer lengths
17.9 + 22.6 + 3x = 64.5
Combine like terms
40.5 +3x = 64.5
Subtract 40.5 from each side
40.5 +3x -40.5 = 64.5 - 40.5
3x =24
Divide each side by 3
3x/3 = 24/3
x = 8
The area of a triangle is given by

Step-by-step explanation:
Fiona must find the length indicated by the dotted line for the tiles she is installing. She knows that each polygon is a regular hexagon with a perimeter of 7.5 in.
3 regular hexagons are connected at their sides. A dotted line is drawn through the middle of the 3 hexagons. The top image is a reflection of the bottom image. The dotted line is the length of one side and the distance from one point of the hexagon to the opposite point.
What is the length of the dotted line? Round to the nearest hundredth.
2.50 in.
3.75 in.
5.00 in.
6.25 in.
The length of the dotted line in the hexagon is 3.75 cm.
What is a hexagon?A polygon with 6 sides is called a hexagon.
Finding the length across one entire hexagon :-
We can draw 6 small triangles from the center of the hexagon. The top vertex of this triangle will be 60°; this is because there are 6 angles, and 360.
The sum of the measures of the angles in a triangle is 180°; taking out the top angle, we have 180-60 = 120°.
Since the triangle is isosceles, the base angles will be equal to 120/2 = 60
The bottom two angles will also be 60°.
This makes the triangle equiangular, which also makes it equilateral; all 3 sides will be 1.25.
Hence,
This means across the dotted line we have 1.25+1.25+1.25 = 3.75.

[tex]\alpha=0.05[/tex] represent the significance level for the hypothesis test.
t would represent the statistic
[tex]p_v[/tex] represent the p value
System of hypothesis
We want to determine the true mean is 41 per day, the system of hypothesis would be:
Null hypothesis:[tex]\mu = 41[/tex]
Alternative hypothesis:[tex]\mu \neq 41[/tex]
We need to find the degrees of freedom first:
[tex] df = n-1= 16-1 =15[/tex]
And the significance level is [tex]\alpha=0.05[/tex] and since we are conducting a bilateral test then the critical values are founded with the t distribution with 15 degrees of freedom and we got:

2. The area of a rectangle is 56 square inches. The rectangle is 8 inches long. How wide is the rectangle?
A.15 inches
B. 7 inches
C.48 inches
D.20 inches
Answer:
B. 7 inches
Step-by-step explanation:
The area of a rectangle is given by
A = l*w where l is the length and w is the width
56 = 8*w
Divide each side by 8
56/8 = 8w/8
7 =w
Answer: 7 inches
Step-by-step-Explanation: The formula for the area of a rectangle is below shown below.
Area = length · width
Since we know that the area of the rectangle is 56 in² and the length of the rectangle is 8 inches, we have 56 = 8 · w.
Now to find w or the width of the rectangle, we divide
both sides of the equation by 8 to get 7 = w.
So the width of the rectangle is 7 inches.
Notice that we include inches in our final answer because we were given inches as units in the original problem.
Also notice that we don't ever have to draw a picture of the rectangle in this problem. We can find our answer by simply using the formula for the area of a rectangle.

Kale can typed 165 words in 3 minutes. How can this ratio be written to show words per minute?
Answer:
55 words per minute
Step-by-step explanation:
165/3
Final answer:
The ratio of words typed per minute for Kale who typed 165 words in 3 minutes is calculated by dividing the number of words by the number of minutes, resulting in 55 words per minute.
Explanation:
To calculate the number of words typed per minute, you take the total number of words typed and divide it by the number of minutes it took to type them. In this case, Kale typed 165 words in 3 minutes, so the ratio of words to minutes is:
165 words / 3 minutes = 55 words per minute
This ratio indicates the typing speed, measured in words per minute (wpm), which is a common way to express typing efficiency.

An elevator started on the 10th floor of a large hospital. it traveled up 4 floors, then down 6 floors, then down 2 more floors, and finally went back up 7 floors. Which floor was the elevator on when it stopped?
After a series of movements starting on the 10th floor, the elevator stopped on the 13th floor.
To determine which floor the elevator was on when it stopped, we need to perform a series of additions and subtractions based on the elevator's movements, as described:
The elevator started on the 10th floor.
It traveled up 4 floors: 10 + 4 = 14th floor.
Then down 6 floors: 14 - 6 = 8th floor.
Then down 2 more floors: 8 - 2 = 6th floor.
Finally, it went back up 7 floors: 6 + 7 = 13th floor.
After completing all these movements, the elevator stopped on the 13th floor.

Ethan Purchased a gently used minivan 2 years ago. the current value of the van is $8000 the vans value depreciated by 11% each year. how much does Ethan pay for the van?
Answer:
18,736.80
Step-by-step explanation:
Final answer:
To determine the original purchase price of the van, we apply the formula for exponential decay and find that Ethan paid approximately $10,100.45 for the van two years ago, taking into account a depreciation rate of 11% per year.
Explanation:
To find how much Ethan paid for the van, we need to work backwards from the current value and consider the annual depreciation rate.
To do this, we can use the formula for exponential decay which is final value = initial value × (1 - rate of depreciation)number of years. Given the final value ($8000) and the depreciation rate (11% or 0.11), we need to solve for the initial value, which represents the price Ethan paid for the van.
Let's set up the equation:
8000 = initial value × (1 - 0.11)2
8000 = initial value × (0.89)2
8000 = initial value × 0.7921
Initial value = 8000 / 0.7921
Initial value ≈ $10,100.45
Therefore, Ethan paid approximately $10,100.45 for the van.
