The coordinates of the point where the chain should attach to the triangle are (3, 4).
Given that, a triangle is on a coordinate plane with coordinates (0,4), (3,8), and (6,0).
We need to find the coordinates of the point where the chain should attach to the triangle.
What is the centroid of the triangle?The centroid is the centre point of the object. The point at which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangle. The centroid of the triangle formula is G = ((x1+x2+x3)/3 , (y1+y2+y3)/3).
Now, centroid = ((0+3+6)/3, (4+8+0)/4)
=(3, 4)
Therefore, the coordinates of the point where the chain should attach to the triangle are (3, 4).

-3(x+5)=-(3x+15) solve for x
Step-by-step explanation:
Simplifying
-3(x + 5) = -1(3x + 15)
Reorder the terms:
-3(5 + x) = -1(3x + 15)
(5 * -3 + x * -3) = -1(3x + 15)
(-15 + -3x) = -1(3x + 15)
Reorder the terms:
-15 + -3x = -1(15 + 3x)
-15 + -3x = (15 * -1 + 3x * -1)
-15 + -3x = (-15 + -3x)
Add '15' to each side of the equation.
-15 + 15 + -3x = -15 + 15 + -3x
Combine like terms: -15 + 15 = 0
0 + -3x = -15 + 15 + -3x
-3x = -15 + 15 + -3x
Combine like terms: -15 + 15 = 0
-3x = 0 + -3x
-3x = -3x
Add '3x' to each side of the equation.
-3x + 3x = -3x + 3x
Combine like terms: -3x + 3x = 0
0 = -3x + 3x
Combine like terms: -3x + 3x = 0

2 digit long multiplication.
__________________________________________
Long multiplication can seem very intimidating, especially if you're multiplying two numbers that are pretty large. If you take it step by step, though, you'll be able to do long multiplication in no time.
First, muiltiply the 3 by 5 and 7, and muiltiply the 2 by 5 and 7 as well.
[tex]\frac{\begin{matrix}\:\:&\:\:&5&7\\ \:\:&\times \:&2&3\end{matrix}}{\begin{matrix}0&1&7&1\\ 1&1&4&0\end{matrix}}[/tex]
(NOTE: Remember when you muiltiply two digit numbers, when you pass from the first digit to the other on the bottom side, you ALWAYS add a zero to the beginning of the result BEFORE multiplying the following digit)
Secondly, once you've multiplied, you add both results of the multiplication.
[tex]\frac{\begin{matrix}\:\:&\textbf{\:\:}&1&\:\:&\:\:\\ \:\:&\textbf{0}&1&7&1\\ +&\textbf{1}&1&4&0\end{matrix}}{\begin{matrix}\:\:&\textbf{1}&3&1&1\end{matrix}}[/tex]

a.
Draw the perpendicular bisector of segment AB.
b. Draw a line through B perpendicular to segment AB.
c. Draw the line passing through A and B.
d. Draw a line parallel to line AB.
The drawing that creates a line of reflection that takes the point A to point B is; D: Draw a line parallel to line AB.
How to create a line of reflection
A line of reflection is a line that lies in a position between two identical mirror images so that any point on one image is the same distance from the line as the same point on the other flipped image.
Let us look at the given options;
A) Draw the perpendicular bisector of segment AB; A perpendicular bisector will NOT create a line of reflection that takes point A to point B but rather it will divide the line AB in two equal parts
B) Draw a line through B perpendicular to segment AB; A line through B perpendicular to segment AB will NOT Create a line of reflection that takes point A to point B
C) Draw the line passing through A and B;
A line passing through A and B will NOT create a line of reflection that takes point A to point B but rather will create Line A and B again and not its reflection
D) Draw a line parallel to line AB;
A line parallel to line AB will create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB.
Thus, the drawing that create a line of reflection that takes the point A to point B is; D: Draw a line parallel to line AB.

Guys i need help making this quadratic equation into a standard form HELP ME PLEASE, ^2 means Like 2 Square.
1.) 11x^2 - 98 = 11 + 9x
2.) (2x - 1)^2 = (x + 4) ^2
3.) 4x^2 + 2x - 9 = (x - 2)(x - 9)
4.) 0 = 6 (x + 7)^2 - 58
5.) - 1/2 ( x - 1/4 )^2 + 12 = 0
Answer:
1) 1x² - 9x - 109 = 0
2) 3x² -12x -15 = 0
3) 3x² + 13x - 27 = 0
4) 6x² + 84x + 236 = 0
5) -16x² + 8x + 383 = 0
Step-by-step explanation:
The standard form of the quadratic equation is ax² + bx + c where a, b and c are constants.
So we have to convert each of the equations into a form that resembles the above
(1) 11x² -98 = 11 + 9x
Simplify both sides of the equation.(2) (2x - 1)² = (x + 4) ²
Simplify both sides of the equation(3) 4x² + 2x − 9 = (x − 2)(x − 9)
Simplify (x−2)(x−9)(4) 0 = 6(x +7 )² - 58
Switch sides:(5) -1/2 ( x - 1/4 )² + 12 = 0

Answer:
Many challenging questions do not involve numerical or geometrical considerations but call for deductive inferences based chiefly on logical relationships. Such puzzles are not to be confounded with riddles, which frequently rely upon deliberately misleading or ambiguous statements, a play on words, or some other device intended to catch the unwary. Logical puzzles do not admit of a standard procedure or generalized pattern for their solution and are usually solved by some trial-and-error method. This is not to say that the guessing is haphazard; on the contrary, the given facts (generally minimal) suggest several hypotheses. These can be successively rejected if found inconsistent, until, by substitution and elimination, the solution is finally reached. The use of various techniques of logic may sometimes prove helpful, but in the last analysis, success depends largely upon that elusive capacity called ingenuity. For convenience, logic problems are arbitrarily grouped in the following categorie

in how many hours will the prices of the two stocks be the same?
In about hours, the prices of the two stocks will be the same.
In roughly 127 hours the prices of the two stocks will be the same.
What do we mean by equations?A mathematical equation is a statement that uses the symbol 'equal to' to connect two expressions with equal values. 3x + 5 = 15, for example. Equations are classified into linear, quadratic, cubic, and other types.So, if we count the hours (x) after 9 a.m., the stock prices will be:
A = $15.97 + $0.11xB = $16.72 - $0.15(x - 3)The value of x when A = B can be calculated using:
A = B
$15.97 + $0.11x = $16.72 - $0.15(x - 3)$15.97 + $0.11x = $16.72 - 0.15x + 0.45$0.11x + 0.15x = $16.72 + 0.45 - $15.97$0.26x = $33.14x = 33.14/0.26= 127.4615384615385Rounding off: 127Therefore, in 127 hours roughly the prices of the two stocks will be the same.

a is its acceleration in meters per second
squared. What is the mass of an object
that has a net force of 65 kg m/s² and an
acceleration of 5 m/s²?
Answer: m = 13 kg
Step-by-step explanation:
This question gives us the formula to use. We will plug-in the values we know and solve for the unknown (mass).
Given:
F = ma
Plug-in known values:
(65 kg m/s²) = m(5 m/s²)

A solution consisting of 90 mg of dopamine in 20 mL of solution is administered at a rate of 8 ml/hr.
A solution of 150 h is administered at a rate of 8 ml / hr.
We express the answer in terms of mg/hr m g / h r
90 mg dopamine / 20 ml = 4.5 mg/ml
4.5 mg/ml * 8 ml/h = 36 mg/h
90 mg * 1 h / 36 mg= 150 h to administer -- using the inverse of 90 mg per 1 hour and cancelling mg in numerator and ml denominator.

Jarome is making pizza. He uses 2 1/2 cups of cheese for
every 2 3/4 pizzas. He has 6 1/4 cups of cheese left in the
bag. How many pizza pies can he make with the leftover
cheese?
Jarome can make 6 whole pizzas with the leftover cheese.
Given that Jarome uses 2 1/2 cups of cheese for every 2 3/4 pizzas. He has 6 1/4 cups of cheese left in the bag.
We need to determine the number of pizza pies can he make with the leftover cheese.
To find out how many pizza pies Jarome can make with the leftover cheese, we need to determine how many sets of 2 3/4 pizzas can be made using 6 1/4 cups of cheese.
Let's start by finding the number of sets of 2 3/4 pizzas that can be made from 6 1/4 cups of cheese:
Number of sets = Total cheese available / Cheese per set
Number of sets = 6 1/4 cups / 2 1/2 cups per set
To make the calculation easier, let's convert all the mixed numbers to improper fractions:
6 1/4 cups = (4 x 6 + 1) / 4 = 25/4 cups
2 1/2 cups = (2 x 2 + 1) / 2 = 5/2 cups
Number of sets = (25/4) / (5/2)
Now, to divide fractions, we invert the divisor (5/2) and multiply:
Number of sets = (25/4) x (2/5)
= (25 x 2) / (4 x 5)
= 50/20
= 5/2
So, Jarome can make 5/2 sets of 2 3/4 pizzas with 6 1/4 cups of cheese.
Now, let's see how many pizzas he can make with the leftover cheese:
To calculate the number of pizzas in 5/2 sets, we multiply it by the number of pizzas per set (2 3/4 pizzas):
Number of pizzas = (5/2) x (2 3/4)
Again, let's convert all the mixed numbers to improper fractions:
2 3/4 pizzas = (4 x 2 + 3) / 4 = 11/4 pizzas
Number of pizzas = (5/2) x (11/4)
Now, when multiplying fractions, we simply multiply the numerators together and the denominators together:
Number of pizzas = (5 x 11) / (2 x 4) = 55/8
So, Jarome can make 55/8 pizzas with the leftover 6 1/4 cups of cheese.
Now, let's simplify the fraction:
55/8 = 6 7/8
Therefore, Jarome can make 6 7/8 pizzas with the leftover 6 1/4 cups of cheese.
Since we can't make a fraction of a pizza, he can make 6 whole pizzas with some cheese left over.

original angle = 34°complement angle = 56°supplement angle = 146°What are defined as the complement and supplement angle?If a sum of two angles is 180 degrees, they are referred to as supplementary angles because they form a linear angle when combined. If a sum of two angles is 90 degrees, they are termed to be complementary angles because they form a right angle when combined.Now, for the given question.
Let the given angle be 'x'.
Then, the complement of the angle will be: 90 - x.
6 times the complement = 6(90 - x)
6 times the complement is 44 less; 6(90 - x) - 44.
Now, the supplement of the angle is; 180 - x.
Two time the supplement = 2(180 - x)
The equation will form as;
2(180 - x) = 6(90 - x) - 44
360 - 2x = 540 - 360 - 44
Simplifying the equation;
x = 34.
Thus, the original angle is 34°.
complement angle = 90 - x
= 90 - 34
= 56°
Thus, complement angle = 56°
supplement angle = 180 - x
= 180 - 34
= 146
supplement angle = 146°
Thus, the values of the angles are obtained.
