−2.4<−2.40
−2.4>−2.40
−2.4≠−2.40
−2.4≤−2.40
Answers
Answer: −2.4≤−2.40
Step-by-step explanation:
Tough one. I judge −2.4 ≤−2.40 to be the correct answer. The difference in significant digits only tells us we don't know for certain that they are equal. But 2.4 MAY be equal, or less than 2.40. None of the others options allows for the fact that they may be equal.
What is the image of the point (- 6, 1) after the reflection over the line y = 2 ?
A. (- 4, 1)
В. (10, 1)
C.(- 6, 3)
D.(- 4, 3)
Answers
The image point is (-6, 3).
What is the image point?According to tradition, the "image" of point P is the reflection of point P across the line, which is designated by the term P' (pronounced "P prime").
The reflection of point (a,b) with respect to line y=k is point (a, 2k -b)
To find the image of the point (-6 ,1);
The formula:
(a, b) → (a, 2k-b)
Here a=-6, b = 1, k = 2
therefore (-6, 1) → (-6, 2×2 (-1))
= (-6, 3)
Hence, the answer is (-6, 3).

a box with a square base is taller than it is wide. in order to send the box through the US mail, the height of the box and the perimeter of the base cna sum to no more than 108 in. what is the maximum colume for such a box
Answers
The given box has the shape of a cuboid, since its height is greater than its width. Thus, the maximum volume for such box is 11200 [tex]in^{3}[/tex].
The volume of an object is a measure of it containing capacity. Since the given box has a taller height than its width, then it has the shape of a cuboid. The volume of a cuboid is given as:
volume = length x width x height
= area x height
Given that the sum of the perimeter of its base and its height is not more than 108 inches, we can say; let the sides of the square base be represented by l and its height by h.
Then;
4l + h = 108
Therefore, maximum volume for the box can be attained when l = 20 inches and h = 28 inches.
So that;
4(20) + 28 = 80 + 28
= 108 inches
Thus;
maximum volume = area of the square base x height
= 400 x 28
maximum volume = 11200 [tex]in^{3}[/tex]
The maximum volume for such a box would be 11200 [tex]in^{3}[/tex].

How to do multiplication large numbers.
Answers
Answer:
The main reason to know the multiplication table is so you can more easily multiply larger numbers. For example, suppose you want to multiply 53 x 7. Start by stacking these numbers on top of another, aligning the ones place. Draw a line underneath, and then multiply 3 by 7. Because 3 x 7 = 21, write down the ones digit (1) and carry the tens digit (2) to the tens column:
Next, multiply 5 by 7. This time, 5 x 7 = 35. But you also need to add the 2 that you carried over, which makes the result 37. Because 5 and 7 are the last numbers to multiply, you don’t have to carry, so write down the 37 — you find that 53 x 7 = 371:
When multiplying larger numbers, the idea is similar. For example, suppose you want to multiply 53 by 47. Be sure to align the stacked numbers by the ones place. (The first few steps — multiplying by the 7 in 47 — are the same, so pick up the next step.) Now you’re ready to multiply by the 4 in 47. But remember that this 4 is in the tens column, so it really means 40. So to begin, put a 0 directly under the 1 in 371:
This 0 acts as a placeholder so that this row is aligned properly.
When multiplying by larger numbers with two digits or more, use one placeholding zero when multiplying by the tens digit, two placeholding zeros when multiplying by the hundreds digit
