Simplifying a ratio of whole numbers: Problem type 1
Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.
40 L: 72 L
Answers
Answer:
5/9
Step-by-step explanation:
You want the reduced fraction equivalent to the ratio 40L : 72L.
Reduced ratioA ratio is reduced by removing the greatest common factor from all parts of the ratio. Here, that factor is 8L.
40L : 72L = (8L)(5) : (8L)(9) = 5 : 9 = 5/9
The ratio is 5/9.
__
Additional comment
The greatest common factor can be found several ways. The easiest is for you to make use of your knowledge of multiplication tables:
40 = 5·8
72 = 9·8
8 is a common factor. Since 5 and 9 have no common factors, 8 is the greatest common factor of 40 and 72.

Prove that a sequence convereges in the standard euclidean metric if and only if it converges in the Taxicab metric (for Rn)
Consider a function d : R^n x R^n → R
(x,y) = |x1-y1| + |x2-y2| + ... + |xn-yn|
Prove that a sequence (xk) converges to a limit x in metric d if and only if it converges to x in the standard Euclidean metric (d). Prove that a set A⊆Rn is open in the metric d0 if and only if it is open in the standard Euclidean metric.
Answers
For all n ≥ N. This suggests that (\(x_n\)) additionally converges to x in the general Euclidean metric
The declaration given at the starting is a frequent characterization of open units in Euclidean spaces.
The assertion truly says that if a set A is open in the popular Euclidean metric, then each factor in A has a
small open ball round it that is additionally contained in A. This is an vital property of open units that
approves us to outline limits and continuity for features on these sets.
Now, believe we have any other metric on the equal space, which we will name the "other metric."
If we can exhibit that each ball of radius ε in the different metric is contained inside some ball of Euclidean radius ε, then we can use the above characterization of open units to conclude that A is open in the different metric as well.
To exhibit that each ball of radius ε in the different metric is contained inside some ball of Euclidean radius ε, we can use the following argument.
Let B(x, ε) be a ball of radius ε in the different metric established at x.
Let y be any factor in B(x, ε).
Then, with the aid of the definition of a ball, the distance
between x and y in the different metric is much less than ε.
Let d be the ratio of the distance between x
and y in the Euclidean metric to the distance between x and y in the different metric.
That is,
d = dist(x, y) / \(dist_{other}\)(x, y)
Since the different metric is equal to the Euclidean metric, we comprehend that d is bounded away from zero and infinity, i.e., there exist superb constants c and C such that c ≤ d ≤ C for all x and y in the space.
Therefore, we have
dist(x, y) ≤ C X \(dist_{other}\)(x, y) ≤ C X ε
This suggests that y is additionally contained inside the Euclidean ball B(x, C*ε)
Finally, we can use these outcomes to show the end result about convergence of sequences.
Let (\(x_n\)) be a sequence in a metric area (X, d). We say that the sequence converges to a restrict x if for each and every ε > 0, there exists an N such that d(\(x_n\), x) < ε for all n ≥ N.
Suppose (\(x_n\)) converges to x in the different metric.
Then, for each ε > 0, there exists an N such that
dist_other(\(x_n\), x) < ε/2 for all n ≥ N.
By the end result we proved earlier, there exists a ball of Euclidean
radius ε/2n that is a subset of the ball of radius ε/2 in the different metric. Therefore, if we pick out N giant ample
so that n > 1/ε, then we have
d(\(x_n\), x) ≤ dist(\(x_n\), x) ≤ two X \(dist_{other}\)(\(x_n\), x) < ε

The impact on Carns’s income from eliminating the Small Tools Division would be: Multiple Choice
Answers
The impact on Carns Company's income from eliminating the Small Tools Division would be a decrease of $1,209,000.
To determine the impact on Carns Company's income from eliminating the Small Tools Division, we need to consider the avoidable costs associated with the division.
The avoidable costs include all of the variable costs of the division and a portion of the fixed costs that are specifically related to the Small Tools Division. In this case, the variable costs of the division are $1,295,000, and $119,000 of the fixed costs are avoidable.
To calculate the impact on income, we subtract the avoidable costs from the loss reported by the division:
Impact on income = Loss - Avoidable costs
Impact on income = $205,000 - ($1,295,000 + $119,000)
Impact on income = $205,000 - $1,414,000
Impact on income = -$1,209,000
The negative sign indicates a decrease in income.

Given: LM ∥ KN
LP ⊥ KN , KL = MN
KN = 30, LM = 20
m∠KLM=126°
Find: LP
Answers
An angle is produced at the point where two or more lines meet. Thus the value of LP required in the question is approximately 14.
Two lines are said to be perpendicular when a measure of the angle between them is a right angle. While parallel lines are lines that do not meet even when extended to infinity.
From the question, let the length of LP be represented by x.
Thus, from the given question, it can be deduced that;
LM ≅ PN = 20
KP = KN - PN
= 30 - 20
KP = 10
LP = x
Also,
<MLP is a right angle, so that;
< KLP = < KLM - <PLM
= 126 - 90
<KLP = \(36^{o}\)
So that applying the Pythagoras theorem to triangle KLP, we have;
Tan θ = \(\frac{opposite}{adjacent}\)
Tan 36 = \(\frac{10}{x}\)
x = \(\frac{10}{Tan 36}\)
= \(\frac{10}{0.7265}\)
x = 13.765
Therefore the side LP ≅ 14.

Manicure sets at nails by Nina are marked up 47% from the cost of $8.36. What does a manicure set cost in Nina’s store?
Answers
Answer:
The cost of a manicure set in Nina's store is $12.30.
Step-by-step explanation:
To find the cost of the manicure set in Nina's store, you can use the following formula:
Selling price = Cost + Cost * Markup percentage
Substituting the given values into this formula, you get:
Selling price = $8.36 + $8.36 * 47%
To find the value of the markup percentage, you can convert 47% to a decimal by dividing it by 100: 47/100 = 0.47
Then you can use this value in the formula to find the selling price:
Selling price = $8.36 + $8.36 * 0.47

The two equations that have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p include the following:
B. 2.3p – 10.1 = 6.49p – 4
C. 230p – 1010 = 650p – 400 – p
How to determine the required equations?From the information provided, we have the following equation:
2.3p – 10.1 = 6.5p – 4 – 0.01p
Next, we would simplify the given equation by collecting like terms as follows;
2.3p - 10.1 = 6.5p - 0.01p - 4 = 6.49p - 4
2.3p - 10.1 = 6.49p - 4
What is the multiplication property of equality?In Mathematics, the multiplication property of equality states that both sides of an equation will remain the same and equal, when both sides of the equations are multiplied by the same number.
By multiplying both sides of the given equation by 100, we have the following;
100 × (2.3p - 10.1) = 100 × (6.5p - 4 - 0.01p)
230p - 1010 = 650p - 400 - p

Given is a triangular prism, we need to find the surface area,
A triangular prism is a 3D shape with two identical faces in the shape of a triangle connected by three rectangular faces. The rectangular faces are referred to as the lateral faces, while the triangular faces are called bases. The bases are also called the top and the bottom (faces) of the prism.
Triangular Prism Meaning: A triangular prism is a 3D polyhedron with three rectangular faces and two triangular faces. The 2 triangular faces are congruent to each other, and the 3 lateral faces which are in the shape of rectangles are also congruent to each other. Thus, a triangular prism has 5 faces, 9 edges, and 6 vertices. Observe the following image of a triangular prism in which l represents the length of the prism, h represents the height of the base triangle, and b represents the bottom edge of the base triangle.
so, the surface area of a triangular prism =
perimeter × length + 2 × base area
So,
SA = (4.5+7.2+9) × 8.1 + 2 × 8.1 × 9
= 167.67 + 145.8
