Answer:
K and L2 are perpendicular.
Step-by-step explanation:
Assume the slope of L1 is X. The slope of L2 is also X.
Using perpendicular slopes, the slope of K is -1/x, meaning it is perpendicular to both L1 and L2.
Is it possible for a metallic element to have a melting point of -38.87 degree celcius? explain.
Answer:
this is not possible
No, it is not possible for a metallic element to have a melting point of -38.87 degrees Celsius under standard conditions.
The melting point of a metallic element is typically a positive value, indicating the temperature at which the solid form of the element transitions into a liquid state.
A negative melting point would be a highly unusual and physically contradictory concept because it would imply that the element exists in a liquid state at temperatures below absolute zero, which is the lowest possible temperature in the Kelvin scale (-273.15 degrees Celsius). At temperatures below absolute zero, the thermal motion of particles comes to a minimum, and it's not possible for a substance to exist in a liquid state.
In reality, metallic elements have melting points that are well above absolute zero, typically ranging from hundreds of degrees Celsius to thousands of degrees Celsius, depending on the specific element. Melting points for metals are typically positive values due to the nature of metallic bonding and the need for sufficient thermal energy to overcome the forces holding the metal atoms together in a solid lattice structure.

The perimeter of a rectangle can be found using the equation P = 2L + 2W where P is the perimeter, L is the length, and W is the width of the rectangle. Can the perimeter of the rectangle be 60 units when its width is 12 units and its length is 18 units?
A) No. If the rectangle has L=18 and W=12, P would not equal 60.
B) No. the rectangle cannot have P=60 and L=18 because L+W is less than 24.
C) Yes. The rectangle can have P=60 and L=18 because 60=24+18.
B) Yes. The rectangle can have P=60 and L=18 because P=2(18)+2(12) would equal 60.

find the area and perimeter
please help me :)
Answer:
Perimeter: 44
Area: 96
Step-by-step explanation:
Perimeter - Just add all the sides together, 4 + 10 + 12 +7 + 8 + 3.
(The 8 and the 3 are apart of the sides that are not labeled. Since 12 - 4 = 8, and 10 - 7 = 3, That's where these numbers come from.)
Area - 4 * 10 = 40,
+ 8 * 7 = 56,
--------------------------------
= 96
I hope this helps :)
Answer:
Perimeter is 44cm
Area is 96cm²
Step-by-step explanation:
Perimeter=side+ side+side.....
●To find the missing horizontal side use the sides they give you :.the horizontal side will be 12-4 =8
●Do the same to find the missing vertical side:
10-7=3
:. Perimeter= 4+10+12+7+8+3
=44
(If you were to skip steps you could've also just seen it as 10+12+10+12=44)
To find area break the shape into manageable shapes you know the area formula of, like 2 rectangles. To help visualize it draw a line separating down from the 3cm vertical side we just calculated.
Area of rectangle 1 = length x breadth
=4×10
=40 units²
Area of rectangle 2 =length x breadth
=7×8
=56 units²
Therefore total area= rectangle 1 + rectangle 2
= 40 units²+ 56 units²
= 96 units²

The top of a hill rises 274 feet above Checkpoint 1.
What is the altitude of the top of the hill? checkpoint 1 = -189
Answer:
Altitude is 215.7ft
c^2 = 215.7ft
Step-by-step explanation:
Altitude means the line of vertex in a triangle that makes a right angle.
Such line forms a perpendicular line to one of the lines within a triangle and either makes a new triangle with 1 line or is a third line of a triangle and is therefore a smaller size to the slope.
Both this found measurement with the other small side must total more than the slope, but when all sides given are squared they must equal the amount of the slope or be the difference when the other perpendicular line is subtracted from the slope, if this was not true a triangle would have wrong term names.
Side^2 + base^2 = slope^2
Vertex^2 + perpendicular^2 = slope^2
= a^2 + b^2 = c^2
So here when given a right angle measure we can use Pythagoras theorem.
274^2 - 169^2 = c^2
sq rt 75076 - sq rt 28561 = c^2
sq rt 46515 = 215.673364 = 215.7
c^2 = 215.7ft
Bare in mind there is no diagram if checkpoint 1 is halfway between the slope then it is a different method and repeat of two slopes.
Therefore the slopes need to be identified if the main slope is split by the vertex line given.

8×2+5^2-y=2(y+1)+6
Answer:
y = 11
Step-by-step explanation:
8 × 2 + 5²- y = 2(y + 1) + 6
8 × 2 + 5²- y = 2y + 2 + 6
8 × 2 + 25 - y = 2y + 2 + 6
16 + 25 - y = 2y + 2 + 6
41 - y = 2y + 8
41 (- y + y) = (2y + y) + 8
41 = 3y + 8
41 - 8 = 3y (+ 8 - 8)
33 = 3y
33/3 = 3y/3
y = 11
-10 + 4n - 3t + 2t + n
If this is just a question to simply this equation, then here's the answer.
-10 + 4n -3t +2t +n
First, add together the n's: 4n+n = 5n
Then, the "t's": 2t - 3t = -t
Since there are no other numbers, you have:
-10 + 5n - t
Answer:
5n-t-10
Step-by-step explanation:
-10 + 4n - 3t + 2t + n
Grouping of like terms
4n + n -3t + 2t -10
5n -t -10

the distributive property for 72+12
Evaluate the expression if m = −4, n = 1, p = 2, q = −6, r = 5, and t = −2.
||16+4(3q+p)||
The value of the given expression for p = 2 and q = −6 is -24.
The given expression is 16+4(3q+p).
We need to evaluate the expression for p = 2 and q = −6.
What is the value of the expression?The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values. The value of a function, given the value(s) assigned to its argument(s), is the quantity assumed by the function for these argument values.
Now, put p = 2 and q = −6 in the given expression and simplify:
That is, 16+4(3(2)+(-6))
=16+4(6-16)
=16+4(-10)
=16-40
=-24
Therefore, the value of the given expression for p = 2 and q = −6 is -24.

1. In the figure below ABC∡=153°, ABD∢=(5x+5)°, and DBC∢=(3x+12)°. Find the measure of ABD∢ and DBC∢. Show all work
If two angles form a large angle when combined, they will follow the angle addition postulate.
Measure of ∠ABD is 90° and the measure of ∠DBC will be 63°.
From the figure attached.
Two angles ∠ABD and ∠DBC are formed at a point B.By angle addition postulate,
m(∠ABD) + m(∠DBC) = m(∠ABC)
Now substitute the values of each angle,
(5x + 5)° + (3x + 12)° = 153°
Combine like terms of the expression,
(5x + 3x) + (5 + 12) = 153
8x + 17 = 153
8x = 153 - 17
x = [tex]\frac{136}{8}[/tex]
x = 17
Substitute the value of 'x' to get the measure of each angle,
m(∠ABD) = (5x + 5)
= 5(17) + 5
= 90°
m(∠DBC) = (3x + 12)
= 3(17) + 12
= 63°
Therefore, m(∠ABD) = 63° and m(∠DBC) = 63° will be the answer.
