Ming says that 0.24 > 1414 because 0.24 = 2424
Final answer:
To compare numbers, we look at their values from left to right. In this case, 1414 is greater than 0.24 due to the magnitude of the numbers.
Explanation:
The student's statement is incorrect. To compare numbers, you look at the digits from left to right, so 0.24 is less than 1 as it's closer to zero. Meanwhile, 1414 is a much larger number because it's in the thousands range.
Therefore, 1414 > 0.24, not the other way around. The student's reasoning based on the equality with 2424 is inaccurate in the context of comparing these two numbers.

What point on the unit circle corresponds to an angle of 173º
The point on the unit circle that corresponds to an angle of 173º is approximately (-0.9917, 0.1288), derived by converting the angle to radians, then calculating the cosine and sine for the x and y coordinates respectively.
Explanation:To find the point on the unit circle that corresponds to an angle of 173º, we first need to convert the angle from degrees to radians. We use the conversion factor of π/180 radians per degree, so 173 degrees is equal to (173)*(π/180) = 3.02 radians.
On the unit circle, the x-coordinate of a point corresponds to the cosine of the angle, and the y-coordinate corresponds to the sine of the angle. In this case, the x-coordinate would be cos(3.02) ≈ -0.9917, and the y-coordinate would be sin(3.02) ≈ 0.1288.
So, the point on the unit circle that corresponds to an angle of 173º is approximately (-0.9917, 0.1288).

The product P of two consecutive natural numbers, the first of which is N
The product of two consecutive natural numbers, with the first being [tex]\( N \),[/tex]is [tex]\( N \times (N + 1) \).[/tex]
The product [tex]\( P \)[/tex] of two consecutive natural numbers can be expressed as the product of a number and its consecutive number. So, if the first number is [tex]\( N \),[/tex] then the second number would be [tex]\( N + 1 \).[/tex] Therefore, the product [tex]\( P \)[/tex] can be written as:
[tex]\[ P = N \times (N + 1) \][/tex]
Expanding this, we get:
[tex]\[ P = N^2 + N \][/tex]
This represents the product of two consecutive natural numbers where [tex]\( N \)[/tex] is the first number.
5.6 times what equals to -19.04
The given equation can be rearranged as a division problem: -19.04 divided by 5.6. The solution to this is -3.4. Thus, 5.6 times -3.4 equals -19.04.
Explanation:To answer the question, we must find the unknown variable in your given equation, where you are multiplying a number (5.6) by some unknown figure to get -19.04. This type of math problem is a division problem arranged differently. Instead of saying '5.6 times what equals to -19.04', we can rearrange it to say '-19.04 divided by 5.6 equals what'.
To get the answer, simply divide -19.04 by 5.6, which equals -3.4. So 5.6 times -3.4 equals -19.04.

Fred worked on Monday and Tuesday, earning $109.30 total for the two days. He had Wednesday off, made $67.89 on Thursday, had a half day on Friday making $35.12, and made $87.34 on Saturday. What is the total amount of money he made that week?
The table of values below represents a linear function and shows the amount of money in a tip jar at a dry cleaners since the dry cleaners opened for the day. How much was in the tip jar when the dry cleaners opened?
A linear equation has a standard form of:
y = mx + b
where in this case,
y = amount of money in tip jar, m = slope, x = number of hours, b = y intercept
We select any two paired data to calculate for the slope:
m = (y2 – y1) / (x2 – x1)
m = (18.25 – 15.50) / (5 – 4)
m = 2.75
y = 2.75x + b
Choosing any one data pair to calculate for b the y-intercept:
15.50 = 2.75 (4) + b
b = 4.5
Therefore there was $4.50 in the tip jar during the opening.
Answer: $4.50
Answer:
4.50
Step-by-step explanation:
from the table, we can tell the tip increases by 2.75 per hour
the 3rd hour: 15.50-2.75=12.75
the second hour: 12.75-2.75=10.00
the 1st hour: 10.00-2.75=7.25
the 0 hour: 7.25-2.75=4.50
so there was 4.50 in the jar

Answer:
13+2+9=2+13+9
[29(14)]+45=[14(29)]+45
Step-by-step explanation:
The equivalent expressions 13 + 2 + 9 = 2 + 13 + 9 and [29(14)] + 45 = [14(29)] + 45 demonstrate the commutative property, according to which the order in which numbers are added or multiplied does not change the result.
Explanation:The commutative property in mathematics is the property that states the order in which numbers are added or multiplied does not change the result. So, looking at the given options, the expressions that demonstrate the commutative property are:
13 + 2 + 9 = 2 + 13 + 9 [29(14)] + 45 = [14(29)] + 45
The other options do not represent the commutative property.
The operation 8 + 0 = 8 is an instance of identity property of addition because any number added to zero gives that number. The expression 9(8 + 45) = 9(8) + 9(45) is an application of the distributive property (where a(b + c) = ab + ac), and 29(14 + 45) = 14(29) + 45 is not a valid mathematical equation since it doesn't balance equally on both sides.Learn more about Commutative Property here:https://brainly.com/question/5637942

The slant height of a cone with a surface area of 500π square feet and a radius of 15 feet is 275 feet.
Explanation:The question asks for the slant height of a cone, given that the surface area (S) is 500π square feet and the radius (r) is 15 feet. No explicit formula for the slant height is provided.
We know the formula for the surface area of a cone is S = πrl + πr², where r is the radius, l is the slant height, and π is a constant (approximately 3.14).
By rearranging this equation, subtracting the base area from the surface area and then dividing by πr, we can solve for l: l = (S - πr²)/πr.
Plugging in the provided numbers: l = (500π - π*(15 ft)²)/(π * 15 ft). Simplifying this equation gives: l = (500 - 225) ft = 275 ft. Therefore, the slant height of the cone is 275 feet.
