A solid aluminum sculpture in the shape of a rectangular prism has a mass of 129, 600 kilograms. The length of the sculpture is 6 meters, the width is 2 meters, and the height is 4 meters. What is the density of aluminum?
If the volume of the aluminum will be 48 cubic m. Then the density of the aluminum will be 2700 kg per cubic m.
What is density?Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
Density = mass/volume
A solid aluminum sculpture in the shape of a rectangular prism has a mass of 129,600 kilograms.
The length of the sculpture is 6 meters, the width is 2 meters, and the height is 4 meters.
Then the density of the aluminum will be
The volume of the aluminum brick will be
V = 6 x 2 x 4
V = 48 cubic m
Then the density will be
D = 129600/48
D = 2700 kg per cubic m

Find the area K of the triangle.
a=4, b=5, C = 25°
K=
square units
(Round to two decimal places
as
needed.)
Answer:
4.23 square units
Step-by-step explanation:
The area of the triangle is given by the formula ...
K = 1/2ab·sin(C)
__
Filling in the given values, we find the area to be ...
K = 1/2(4)(5)sin(25°) = 4.23 . . . . square units
Find equation of the straight line that passes through the point (-1,1) and is perpendicular to 2y = 3x +2
Answer:
3y = -2x + 1
Step-by-step explanation:
Equation of given line is 2y = 3x + 2
==> y = (2/2)x + 1
Slope = 3/2
Slope of perpendicular line is negative of reciprocal of given line ie slope = -2/3
So equation of perpendicular line is of the form
y = (-2/3)x + c where c is a constant
Given that this passes thru x= -1, y =1 we can substitute these values in the above to get
1 = (-2/3)(-1) + c
This yields 1 = (2/3) + c or c = 1-2/3 = 1/3
So the equation of the perpendicular line is
y = (-2/3)x + 1/3
3y = -2x + 1
Is AABC™ADEF? If so, identify the similarity postulate or theorem that
applies.
A. Similar - AA
B. Similar - SSS
C. Similar - SAS
D. Cannot be determined
Answer:
A. Similar - AA
Step-by-step explanation:
The AA similarity postulate states that two triangles are similar if they have two congruent corresponding angles.
The triangles in the picture have two corresponding congruent angles.
Similar triangles may or may not be congruent
The true statement is (a) Similar - AA
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
From the complete question, we have the following highlights about the triangles
The angles at points A and D are congruent (85 degrees)
The angles at points B and E are congruent (30 degrees)
This means that the triangles are similar.
The similarity theorem is the AA theorem i.e. Angle-Angle
Hence, the true statement is (a) Similar - AA

Find the equation of a line parallel to y-5=6x-10 that passes through (4,10)
[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond[/tex]
❖ If lines are parallel to each other, they have the same slope.
So the slope of the line parallel to y-5=6x-10 is 6.
Now, since we're also given the point crossed by the line, we write the equation in point-slope form:-
[tex]\sf{y-y_1=m(x-x_1)}[/tex]
Substitute 10 for y₁, 6 for m and 4 for x₁:-
[tex]\sf{y-10=6(x-4)}[/tex]
On simplification,
[tex]\sf{y-10=6x-24}[/tex]
Adding 10 to both sides results in:-
[tex]\sf{y=6x-14}[/tex]
So we conclude that Option A is correct.

how much greater is 8 x 10 to the 5 power then 8 x 10 to the -1 power
Answer:
8x10 to the 5 power is 8,000,000 and 8x10 to the -1 power is .8
Step-by-step explanation:
To solve the first problem, you multiply 8 and 10 which gives you 80. Next you move the decimal point 5 spaces to the right which gives you 8,000,000. To solve the second problem, you multiply 8 and 10 which gives you 80. Because you have a negative power you move your decimal point to the left 1 space which gives you .8
Can someone please help me with this
Answer:
First step, find the missing angle (you will need this later on)
We know that the sum of all angles in a triangle equals to 180°, so
180° - 65° - 40° = 75° *that's your angle (next to the point L)
Now, identify each side (as shown in my drawing attached to this message)
The law of sines tells us that
(for example) the side opposite to L (highlighted in pink in the drawing) divided by the sine of the angle at the point L (in our case, 75°) creates a ratio that remains the same for the other sides.
So,
pink side (opposite to L)/ sin 75 (angle at L) = yellow side (opposite to J)/ sin 65 (angle at J) = blue side (opposite to K)/ sin 40 (angle at K)
*Careful, since we were not given the length of one side, you cannot find actual values for each side. Although, you can use the law of sines to logically find out which length is the longest and which one is the shortest.
*Notice that the sine of the angle relates to the length of the coloured sides
Calculate the following: sin 75, sin 40, sin 65.
Once you do that, you will realize that sin 40 = to the smallest value and that sin 75 gives you the largest value.
Thus, sin 40 < sin 65< sin 75
Which corresponds to (from smallest to largest):
blue side, yellow side, pink side
*Now, write your answer in a mathematical format (using J,L,K points)
blue = JL (explanation: it connects the two points, LJ is also a valid answer)
yellow = LK
pink= JK
ANSWER: JL, LK, JK
Step-by-step explanation:
Use the Law of Sines *because you don't have a right angle triangle.

Step-by-step explanation:
The equation of finding the area of a triangle is 1/2 base x height so the base is 7 and the height is 1.5. The slant of the triangle doesn't change the area and those measurements are just there to confuse you. so just input the measurements to get:
1/2 x 7 x 1.5 = 3.5 x 1.5 = 5.25cm^2

Francis works and earns $3437 dollars but on a pay stub pays 42% to tax.
Answer:
Francis has $1,993.46 left of his pay stub
Step-by-step explanation:
earns $3437 dollars
42% to tax (yikes! almost half of their pay)
42% of $3437 dollars: $3437 x 0.42 = 1,443.54
Francis is paying $1,443.54 in taxes
$3437 - $1,443.54 = $1,993.46

There are 10 participants in the Olympic 100 meter sprint. If first, second, and third place get medals, how many possible outcomes of medal winners are there if Usain Bolt places first?
Answer:
56
Step-by-step explanation:
with Usain Bolt getting the the first place there is only 9 other contestants that can get the two other available medal position. When the second place is taken, there will be 8 remaining contestants for a third place therefore you do 9 multiplied by 8 to get 56 differrent combinations of contestants for the third or second place medal

Answer:
22cm
Step-by-step explanation:

Answer:
m∠R = 72°; m∠U = 65°
Step-by-step explanation:
We know that in any quadrilateral, the total sum of the angles will always add up to 360°.
For number 26, we can use this equation to find x and m∠R:[tex]90+98+12x+4+10x-8=360\\(90+98+4-8)+(12x+10x)=360\\184+22x=360\\22x=176\\x=8[/tex]
m∠R = 10 (8) - 8 = 80 - 8 = 72°
For number 28, we can use this equation to find x and m∠U
[tex]96+88+11x+1+7x-5=360\\(96+88+1-5)+(11x+7x)=360\\180+18x=360\\18x=180\\x=10[/tex]
m∠U = 7 (10) - 5 = 70 - 5 = 65°
