Answer: radius = 6.18 (I don't know what solutions you have, but the actual answer for the radius is about 6.18 cm so which ever is closest.)
Step-by-step explanation:
the area of a circle is \pi r^{2}
*rewrite your equation solving for radius
r=\sqrt{A/\pi } =\sqrt{120/\pi } = 6.18
To find the Radius of a circle with an area equal to the area of a rectangle, multiply the length and width of the rectangle to get its area, then use the formula A = πr² to solve for the radius.
To find the Radius of a circle with an area equal to the area of a rectangle, we need to find the area of the rectangle and then calculate the radius of the circle using that area.
The area of the rectangle is found by multiplying the length and width, which in this case is 15 cm * 8 cm = 120 cm².
The area of a circle is given by the formula A = πr², where A is the area and r is the radius. Since the area of the rectangle is equal to the area of the circle, we can set up the equation 120 cm² = πr².
Solving for r, we get r ≈ 6.94 cm (rounded to two decimal places).

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.

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%

- 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.

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

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.

B) (3, 2/3)
C) (2/3, 3)
D) (18, 6)what is the answer
Answer:
D
Step-by-step explanation:
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 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.

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.

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]
