Answer:
LCD = 20
Step-by-step explanation:
1/10 = 2/20
2/4 = 10/20
The least common denominator (LCD) of fractions 1/10 and 2/4 (which simplifies to 1/2) is 10. We obtain this by finding the smallest multiple of the largest denominator, 10, that the other denominator (2) can divide.
Explanation:Looking to find the least common denominator of the fractions 1/10 and 2/4, we first need to simplify the fractions to their lowest terms. The fraction 2/4 can be simplified to 1/2. So now we are finding the least common denominator of 1/10 and 1/2.
Define the least common denominator (LCD): It's the smallest multiple that is exactly divisible by every denominator of the set of fractions.
Start from the largest denominator, which is 10 in this case, and list its multiples: 10, 20, 30, etc. Select the smallest multiple that the other denominator(s) (i.e. 2) can divide. You notice that 2 can divide 10, so the least common denominator of these fractions is 10.
So, the answer is that the least common denominator of the fractions 1/10 and 2/4 (or 1/10 and 1/2 in simplest form) is 10. This step-by-step explanation should provide you with an understanding of how to find the least common denominator of two fractions.

15. Explain how you can calculate each square
root mentally.
a) 31 x 31
b) 431 X 431
c) 17 squared
d) 432 squared
Final answer:
Mentally calculating square roots for perfect squares like 31 x 31 or 17 squared is identifying the number that was squared, for instance, 31 or 17 respectively. Larger numbers may require a calculator.
Explanation:
The question is asking how to mentally calculate the square roots of certain numbers. For perfect squares, such as 31 x 31 or 17 squared (which is 17 x 17), the process is straightforward because the square root of a perfect square is the number that was squared.
For instance, the square root of 31 x 31 is 31, and the square root of 17 squared is 17. However, for large numbers like 431 x 431 or 432 squared, while they are also perfect squares, mental calculation might be impractical due to their magnitude, and a calculator would typically be used.
On Monday, Ken spent half of his money on a new game. The next doy he earned $ 12 mowing lawns He now has $32. How much money did Ken hoy before bought the game ?
Answer: 40$
Step-by-step explanation: before the mowing 20$ if half is on the game before game would be 40
Answer:
He had $ 40 before bought the game.
Step-by-step explanation:
Let x be the original amount ( in dollars ) contained by Ken,
His spending on game = half of his money = [tex]\frac{x}{2}[/tex]
So, the remaining money = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]
Now, his earning = $ 12,
Thus, final amount he has = remaining amount + earning
[tex]\frac{x}{2}+12[/tex]
According to the question,
[tex]\frac{x}{2}+12=32[/tex]
[tex]\frac{x}{12}=20[/tex]
[tex]\implies x= 40[/tex]
Hence, he had $ 40 before bought the game .

With water from one hose, a swimming pool can be filled in 9 hours. A second, larger hose used alone can fill the pool in 2 hours. How long would it take to fill the pool if both hoses were used simultaneously?
1/9 + 1/2 = 1/x
Let x = length of time it will take both hoses to work together
Multiply both sides by 18x.
2x + 9x = 18
10x = 18
x = 18/10
x = 9/5
x = 1.8 hours
In other words, if both hoses work together, the pool can be filled in 1 hour and 48 minutes.

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have an angle PQR is dilated by a scale factor of 3 using the origin as the centre.
Here the point P is not given, so we are assuming the point P is (6, 2)
After dilated by a scale factor of 3 using the origin as the centre:
P' = (6×3, 2×3)
P' = (18, 6)
Thus, after dilated by a scale factor of 3 using the origin as the centre the point P(6, 2) become P'(18, 6) option (D) is correct.

What decimal is equal 35%
Answer: 0.35
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 35% as the ratio 35 to 100 or 35 ÷ 100. Remember that dividing by 100 moves the decimal point 2 places to the left. Therefore, 82 ÷ 100 would move the decimal point 2 places to the left which would give us .35 or 0.35.
35% can be written as the decimal 0.35.
The decimal equivalent of 35% is 0.35 .
Given,
35%

The great factory makes 6,793 toys each day. It makes 257 more toys than the super toy factory. How many toys does the super toy factory make each day?
Final answer:
The super toy factory makes 6,536 toys each day, which is calculated by subtracting the 257 additional toys made by the great factory from its total production of 6,793 toys.
Explanation:
To determine how many toys the super toy factory makes each day, we need to subtract the number of additional toys made by the great factory from its total daily production. The great factory makes 6,793 toys each day and it makes 257 more toys than the super toy factory. So:
Number of toys made by the super toy factory = Number of toys made by the great factory - Extra toys made by the great factory
Number of toys made by the super toy factory = 6,793 - 257
After performing the subtraction:
Number of toys made by the super toy factory = 6,536
Therefore, the super toy factory makes 6,536 toys each day.
SV is an angle bisector of ∠RST. If m∠RSV = (2x + 8)° and m∠RST = (6x − 26)°, find x.
Answer:
x = 21
Step-by-step explanation:
Given that SV is the angle bisector of ∠RST, then
∠RSV = ∠TSV, thus
∠RSV + ∠TSV = ∠RST ← substitute values
2x + 8 + 2x + 8 = 6x - 26, that is
4x + 16 = 6x - 26 ( subtract 6x from both sides )
- 2x + 16 = - 26 ( subtract 16 from both sides )
- 2x = - 42 ( divide both sides by - 2 )
x = 21

- In your opinion, should Cromwell have treated
the rebels so harshly? (Explain with evidence)
Answer:
yes they were rebels
Step-by-step explanation:
respect is earned, if you act a certain way you will be treated like that
Cromwell's harsh treatment of rebels during the English Civil War can be seen as a pragmatic approach to maintain discipline and discourage uprisings, but also as excessively cruel and counterproductive, particularly in the case of his actions in Ireland. It's worth noting that historical judgments depend heavily on the values and perspectives applied to the past.
Explanation:Whether Oliver Cromwell should have treated the rebels so harshly during the English Civil War is a matter of perspective and is heavily debated among historians. Cromwell is known for his decisive, and yes, often harsh measures against those who rebelled against the Parliamentarian cause during the war. From a pragmatic viewpoint, one might argue that his harsh treatment of the rebels was necessary to maintain discipline and to discourage other potential uprisings. This included the crushing of the Levellers in the New Model Army and his later actions in Ireland.
However, there is also a compelling argument that his actions were excessively cruel and counterproductive to his stated goals. Numerous historical accounts indicate that his actions in Ireland, including the infamous massacre at Drogheda, served to perpetuate animosity towards English rule, contributing to centuries of tension and conflict.
The difficulty with questions like these is that they often involve value judgements. History, as a discipline, attempts to understand the past 'as it really was', acknowledging that people of the past operated according to different sets of values and contexts.

Plz help!!!!
Answer:
Dog: 20
Dolphin: -6
Octopus: -30
Step-by-step explanation:
The dog is at 20 because it is above sea level meaning it is above the zero, meaning it is plus +
The dolphin is at -6 because it is below sea level meaning it is below zero meaning its a negative -
The octopus is at -30 because it is below sea level meaning it is below zero meaning its a negative -
(Any Thing Below Zero is a Negative & Anything Above Zero is a Positive)
The elevation of the dog is 20 feet.
The elevation of the dolphin is -6 feet.
The elevation of the octopus is -30 feet.
Given,
A dog is standing on a cliff 20 feet above sea level.
A dolphin is swimming 6 feet below sea level.
An octopus is moving along the seabed, 30 feet below sea level.
We need to find out what is the elevation of the dog, dolphin, and octopus.
How do we describe elevation?When we measure the distance we always measure it from the sea level.
The distance measured below the sea level is always described as a negative value.
The distance measured above sea level is always described as a positive value.
We have,
A dog is standing on a cliff 20 feet above sea level.
This is above sea level so we can describe it as:
The elevation of the dog is 20 feet.
A dolphin is swimming 6 feet below sea level.
This is below sea level so we can describe it as:
The elevation of the dolphin is -6 feet.
An octopus is moving along the seabed, 30 feet below sea level.
This is below sea level so we can describe it as:
The elevation of the octopus is -30 feet.
Thus,
The elevation of the dog is 20 feet.
The elevation of the dolphin is -6 feet.
The elevation of the octopus is -30 feet.

Answer:
The volume of the box is 3/4 cubic meters.
Step-by-step explanation:
We know that volume = length * width * height. We have length, width, and height already, so all we have to do is multiply.
5/6 * 1 1/8 * 4/5. First we convert 1 1/8 from a mixed fraction, to give us 9/8, as 8/8 = 1.
5/6 * 9/8 * 4/5. 5 * 9 = 45, and 6 * 8 = 48. 45/48 reduces to 15/16.
15/16 * 4/5. 15 * 4 = 60, and 16 * 5 = 80. 60/80 reduces to 6/8, which reduces to 3/4.
