ABC=CDE when ABC=61 then CDE=2X 2X=61 --> X=61/2=30.5
The value of x would be equal to 30.5
What are vertical angles?Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
We are given that if ∆ACB ≅ ∆DCE,
∠ABC=61°,
∠BCA=57°
∠CDE=2x
Therefore,
ABC = CDE
then CDE = 2X
2X = 61

15. Ankita bought 20 copy for Rs. 25 each. She got profit of Rs.200 while selling it. Find selling price of the copies. no
Answer:
SP=Rs.700
Step-by-step explanation:
cost price of a copy=R's.25
cost price of 20copy=20×25=Rs.500
profit=Rs.200
selling price of 20 copies=?
Now, we know that,
profit=sp-cp
or, 200=sp-500
or, 200+500=sp
thus, SP=Rs.700
Hence, the selling price of 20copies is 700.

Find the probability of no successes in six trials of a binomial experiment in which the probability of success is 30%.
Answer: 0.02655
Step-by-step explanation:
Explanation: The formula for finding the probability of no successes in a binomial experiment is given by (1 - p)^n, where p is the probability of success in a single trial and n is the number of trials. In this case, p = 0.30 and n = 6. So, the probability of no successes is (1 - 0.30)^6 = 0.02655.
Find the side of an equialateral triangle if it's area is 9√3 cm2
Step-by-step explanation:
We know that the area of an equilateral triangle of side a cm is
\( \rm \: Equilateral \: Triangle = \cfrac{ \sqrt{3} }{4} {a}^{2} \: cm\)Let a cm here be 9√3 then we could get our solution.
\( \rm\implies \rm 9 \sqrt{3} = \cfrac{ \sqrt{3} }{4} \: a {}^{2} \)
\( \implies \rm \: \cfrac{ \sqrt{3} }{4} {a}^{2} = 9 \sqrt{3} \)
\( \implies \rm \: a {}^{2} = 36\)
\( \implies \rm \: a = \sqrt{36} = \sqrt{6 \times 6} \)
\( \implies \rm \: a = 6 \: cm\)
Thus, the side of the equilateral triangle is 6 cm.

6 minutes 20 seconds into seconds.
Answer:
380 seconds
Step-by-step explanation:
Convert 6 minutes to seconds by multiplying 6 times 60, because there are 60 seconds per minute.
6 x 60 = 360
Now add the 20 seconds.
360 + 20 = 380
6 minutes and 20 seconds are equal to 380 seconds.

--|-----------------------------------
Key: 3|2 means 3.2
What is the mean, and what does it tell you in terms of the problem?
A 3.85 feet; The value means that a typical throw of the ball results in 3.85 feet.
B 3.2 feet; The value means the furthest the ball went.
C 5.1 feet; The value means this measurement had the most occurrences.
D 4.62 feet; The value means that a typical throw of the ball results in 4.62 feet.
Answer:
D. 4.62 feet.
-
The value means that a typical throw of the ball results in 4.62 feet. To calculate the mean from a stem-and-leaf plot, we add up all the data points and divide by the total number of points. In this case, that is (0 + 1 + 4 + 1 + 2 + 6 + 1 + 3 + 7 + 1 + 1 + 5) / 12 = 4.62. This mean value tells us that the average distance a heavy ball is thrown is 4.62 feet.
Answer:
To find the mean distance that the heavy ball was thrown, we need to find the sum of all the distances and divide by the total number of distances.
The data from the stem-and-leaf plot can be written as:
20, 21, 24, 31, 32, 36, 41, 43, 47, 51, 51, 56
There are a total of 12 distances, so we can calculate the mean as:
(mean) = (sum of distances) / (number of distances)
(mean) = (20 + 21 + 24 + 31 + 32 + 36 + 41 + 43 + 47 + 51 + 51 + 56) / 12
(mean) = 432 / 12
(mean) = 36
Therefore, the mean distance that the heavy ball was thrown is 36 feet.
Option A is incorrect because the calculated mean is 36 feet, not 3.85 feet.
Option B is incorrect because the stem-and-leaf plot does not provide information about the furthest distance that the ball was thrown.
Option C is incorrect because while the value 51 appears twice, it is not the mode of the data (which would require a value to appear more frequently than any other value).
Option D is incorrect because the calculated mean is 36 feet, not 4.62 feet.
The correct answer is A: 3.85 feet; The value means that a typical throw of the ball results in 3.85 feet.
Calculate the sector area: 16 in 90°
Therefore , the solution of the given problem of area comes out to be
r = 8.
Define area.The term "area" describes the amount of space occupied by a 2D form or surface. We use cm2 or m2 as our units for measuring area. A shape's area is determined by dividing its length by its breadth.
Here,
A 90 degree sector occupies 1/4 of a circle, which has 360 degrees. Consequently, the area of the whole circle can be written as
Sector Size/Sector Area = Circle Area/360
16 ft2/90 = n/360
(360) (16 ft2)/90 = n
(4)(16 ft2) = n
The total size of the circle is n = 64 ft2.
Since Area of a Circle equals r2,
∏r2 = 64
r2 = 64/∏
r = √(64/∏)
We multiply by / to get by rationalizing the denominator.
r = √(64∏)/√(∏2) Then using the denominator's square root, we can obtain the solution of
r = √(64∏)/∏
r = 8
Therefore , the solution of the given problem of area comes out to be
r = 8.

The coordinates of the reflected point P' will be (4, -3).
When a point is reflected over the x-axis, its y-coordinate changes sign.
In this case, the point P has coordinates (4,3).
To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.
So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.
Therefore, the coordinates of the reflected point P will be (4, -3).

The formula for the centripetal force, as a function of the radius, is given as follows:

What is a proportional relationship?The equation that defines a direct proportional relationship is given as follows:
y = kx.
In which k is the constant of proportionality.
For an inverse proportional relationship, the equation is given as follows:
y = k/x.
The centripetal force varies inversely with the radius, hence the equation is given as follows:
F = k/r.
When F = 56, r = 16, hence the constant k is obtained as follows:
56 = k/16
k = 56 x 16
k = 896.
Hence the equation is given as follows:
F = 896/r.

Answer:
x = -4, y = 1
x = -1, y = -2
Step-by-step explanation:
(1) x + y = -3 (2) y = \(x^{2} +4x + 1\)
y = -x - 3 -x - 3 = \(x^{2} +4x + 1\)
\(x^{2} + 5x + 4 = 0\\\)
(x + 4)(x + 1) = 0
x = -4 or x = -1

What is Pythagorean Theorem?In mathematical terms, if y and z are the lengths of the two shorter sides (also known as the legs) of a right triangle, and x is the length of the hypotenuse, the Pythagorean theorem can be expressed as:
x² = y² + z²
In the questions given, the only one we can use Pythagorean theorem to solve is the one with ladder since it's forms a right-angle triangle.
To calculate the length of the ladder, we can write the formula as;

a contracter purchases 7 dozen pair of padded work glovs for $103.32. he incorrectly calculates the unit price at $14.76 what error did th contractor make
Answer:
The contractor made an error in calculating the unit price of the padded work gloves.
Step-by-step explanation:
To find the unit price of an item, we need to divide the total cost of the item by the number of units purchased. In this case, the contractor purchased 7 dozen pair of padded work gloves, which is equal to 7 x 12 = 84 pair of gloves. Therefore, the unit price of the padded work gloves is $103.32 / 84 pair = $1.23 per pair.
The contractor incorrectly calculated the unit price as $14.76, which is an error of $14.76 - $1.23 = $13.53. This error occurred because the contractor did not correctly take into account the number of units purchased when calculating the unit price.
Hope this helps:)
