What is the total number of unique triangles with side lengths of 4 centimeters. 5 centimeters, and 10 centimeters that can be drawn
There is only one unique triangle that can be drawn with side lengths of 4cm, 5cm, and 10cm.
Explanation:A triangle is defined by its side lengths. In order for a triangle to be formed, the sum of any two side lengths must be greater than the third side length. In this case, we have side lengths of 4cm, 5cm, and 10cm. We can check if these lengths can form a triangle by checking the triangle inequality:
4cm + 5cm > 10cm: This is true, as 9cm is greater than 10cm.4cm + 10cm > 5cm: This is true, as 14cm is greater than 5cm.5cm + 10cm > 4cm: This is true, as 15cm is greater than 4cm.Since all three inequalities are true, a triangle can be formed with side lengths of 4cm, 5cm, and 10cm. Therefore, there is only one unique triangle that can be drawn with these side lengths.
round 47 963 to the nearest hundreds
Answer:
48,000. Look at the tens place, If the number is 5 or higher then you round up, if its 4 or lower the hundreds place stays the same. Since the number in the tens place is higher than 4 you round up, meaning you would add 1 to 9 which give you ten. You would carry that ten over, giving you 48,000
The correct answer is 48,000.
To round the number 47,963 to the nearest hundreds:
Identify the digit in the tens place, which is 6.
Since the digit in the tens place is greater than or equal to 5, round up the hundreds place.
The current digit in the hundreds place is 9.
Rounding up the hundreds place from 9 results in increasing it to the next number, which is 10.
When the hundreds place increases to 10, it affects the thousands place as well:
The 7 in the thousands place becomes 8, because adding 1 to 9 in hundreds place essentially adds 1,000 to the overall number.
Set all digits to the right of the hundreds place to zero.
Thus, 47,963 rounded to the nearest hundreds becomes 48,000.
This process ensures accurate rounding based on standard rounding rules.

Peter calculated that the theoretical probability of obtaining exactly two heads when flipping six coins is 23.4%. What number of heads also has a 23.4% theoretical probability of coming up when 6 coins are flipped?
Answer:
The theoretical probability of obtaining exactly four heads when flipping six coins is also 23.4%.
Step-by-step explanation:
Getting x successes out of n trials is a binomial distribution and is given by:
p(x) = [tex]nC_{x} p^{n-x} q^{x}[/tex]
Here, n = 6
x = 2
p = probability of one head = [tex]\frac{1}{2}[/tex]
q = 1 - p
= [tex]1-\frac{1}{2}[/tex]
= [tex]\frac{1}{2}[/tex]
Substitute these values, we get,
p(2) = [tex]6C_{2} (\frac{1}{2} )^{6-2} (\frac{1}{2} )^{2}[/tex]
= [tex]15(\frac{1}{2} )^{6}[/tex]
= [tex]\frac{15}{64}[/tex]
= 0.234
= 23.4%
We know that [tex]6C_{2} =6C_{6-2}[/tex]
[tex]6C_{2} =6C_{4}[/tex]
Now,
p(4) = [tex]6C_{4} (\frac{1}{2} )^{6-4} (\frac{1}{2} )^{4}[/tex]
= [tex]15(\frac{1}{2} )^{6}[/tex]
= p(2)
Hence, the theoretical probability of obtaining exactly four heads when flipping six coins is also 23.4%.

Find the 52nd term. 28, 25, 22, 19, ..
Answer:
The 52nd term is -125
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
where a1 is the first term and d is the common difference.
a1 = 28
d = 25-28 = -3
Let's check 19-22 = -3 so the common difference is correct
an = 28 - 3(n-1)
We want to find the 52 term so n = 52
a52 = 28 -3 (52-1)
a52 = 28 -3(51)
a52 = 28 -153
a52 = -125

In triangle DEF, DF = base = 4a and height = 2b.
Hence area of triangle DEF = 1/2 hy = 4ab
In triangle QRP, base QR = line joining mid points of sides DE and EF
= 1/2 (DF) = 2a
Height =b
So area of triangle DEF = 1/2 (2a)b = ab
i.e. Area of triangle DEF = 4 times triangle QRD
It follows that in an isosceles triangle, if QR is the mid points of isosceles sides, then triangle QRD has 1/4 times area of triangle DEF

Without graphing, classify each system as independent, dependent, or inconsistent. y = 3x + 6, 6x - 2y = -12
Answer:
The correct answer option is dependent.
Step-by-step explanation:
We are given the following two equations and we are to determine whether these are independent, dependent or inconsistent:
[tex]y = 3x + 6[/tex] --- (1)
[tex]6x - 2y = -12[/tex] --- (2)
To compare these equations with each other, it is a good idea to write them in the same format with y being the subject. So rearranging equation (2) to get:
6x - 2y = -12
6x + 12 = 2y
2y = 6x + 12
y = 3x + 6
A system of equations is said to be dependent when the same line is written in two different forms so that there are infinite solutions.
Hence, this system of equations is dependent having infinite solutions.
The system of equations are classified as independent
How to determine the termTo classify the system of equations as independent, dependent, or inconsistent, we can analyze their coefficients.
The given system of equations is:
y = 3x + 6
6x - 2y = -12
Comparing the coefficients, we can see that the slopes of the equations are equal (-2/-6 )
Reduce the fraction to smaller forms, we get;
1/3
Now, since the slopes are different, the system is consistent and has a unique solution, indicating an independent system.
Thus, the equations are independent.

Step-by-step explanation:
11. Circumcentre
Your points form the vertices of a right triangle (see image below).
The circumcentre (O) of a right triangle must be at the midpoint of the hypotenuse.
Your hypotenuse has the ends at (-3,4) and (1,1), so
O = ((-3 + 1)/2),(4 + 1)/2))
O = (-2/2,5/2)
O = (-1, 5/2)

please help :))) will award brainliest <3
Alright, so we are given a triangle where all the angles are the same. Now - we need to write a proof that when IE bisects KM, it creates equal angles.
Given:
IKM is equiangular
IE is perpendicular to KM
This is enough to prove that IKE is congruent to IME because:
IEK and IEM are both 90 degrees, since IE is perpendicular to KM
KIE and MIE are the same degree measure, since I is being bisected.
This leaves us with only one angle remaining, and since we already know that the first two angles are congruent to their counterpart - we also know that IKE is congruent to IME because all interior angles of triangles add up to 180°, and we know the other two angle sets to be congruent.
Which value is a solution to the inequality 9 – y >12?
A. –3
B. –6
C. 8
D. 2
Answer:
B
Step-by-step explanation:
solving the inequality
9 - y > 12 ( subtract 9 from both sides )
- y > 3 ( multiply both sides by - 1 )
Remembering to reverse the inequality symbol when multiplying/ dividing by a negative quantity
y < - 3 ← reverse symbol
Thus y is less than or equal to - 3
The only value from the list which makes this true is - 6 → B
To find a solution to the inequality 9 – y > 12, one must first simplify the inequality to y < -3. After comparing all the options, the correct answer is Option B (– 6), as it is the only value that is less than -3.
Explanation:The question asks to find a value of y that satisfies the inequality 9 – y > 12.
To find the solution, we need to isolate y on one side of the inequality:
Subtract 9 from both sides: 9 – y - 9 > 12 - 9, which simplifies to –y > 3.Multiply both sides by -1. Remember that multiplying or dividing both sides of an inequality by a negative number reverses the inequality sign: y < -3.Now that we have the solution to the inequality, we can evaluate the given options.
Option A: – 3 is not greater than -3 (it is equal).Option B: – 6 is less than -3, so it satisfies the inequality.Option C: 8 is not less than -3.Option D: 2 is not less than -3.Therefore, the correct answer is Option B: – 6, because – 6 < – 3.
The length of a rectangle is 3 meters less than four times the width the perimeter of the rectangle is 74 meters. find the length and width of the rectangle
width = perimeter/2 - length
w = 74/2 - 5 = 32
32/4 = 8 - 3 = 5
The length of the rectangle is 5.
The width of the triangle is 32
As per the given values, the length of the rectangle is 29 meters and the width is 8 meters.
Explanation:To find the length and width of the rectangle, we can use the information given: the length is 3 meters less than four times the width, and the perimeter is 74 meters. Let's assume the width is 'w' meters. So, the length would be '4w - 3' meters. The perimeter of a rectangle is found by adding the lengths of all its sides, which in this case is twice the length plus twice the width.
We can set up an equation to solve for 'w': 2(4w - 3) + 2w = 74. Solving this equation will give us the width of the rectangle, and we can substitute that value back to find the length.
Step 1: Set up the equation:
2(4w - 3) + 2w
= 74.
Step 2: Simplify the equation:
8w - 6 + 2w
= 74.
Step 3: Simplify further:
10w - 6 = 74.
Add 6 to both sides.
Step 4: Continue to simplify:
10w = 80.
Divide both sides by 10.
Step 5: Solve for 'w':
w = 8.
The width of the rectangle is 8 meters.
Step 6: Find the length
= 4w - 3
= 4(8) - 3 = 32 - 3
= 29 meters.
