The result of the expression (28 x 28 x 3.14) - (18 x 18 x 3.14) is 20940.80.
Given that:
Expression:
(28 x 28 x 3.14) - (18 x 18 x 3.14)
To calculate the given expression, follow these steps:
First, evaluate the expressions inside each set of parentheses.
Next, perform the arithmetic operations based on the calculated values.
Step 1:
(28 x 28 x 3.14)
The 28 × 28 is equal to 784, then
(28 x 28 x 3.14) = 784 × 3.14
(28 x 28 x 3.14) = 2461.76
(18 x 18 x 3.14)
The 18 x 18 is equal to 324, then
(18 x 18 x 3.14) = 324 × 3.14
(18 x 18 x 3.14) = 1017.36
Step 2:
21952.64 - 1011.84 = 20940.80
So, the result of the (28 x 28 x 3.14) - (18 x 18 x 3.14) is 20940.80.

Find x.
Round to the nearest tenth.
7cm 7cm 10cm x
x = [? ]cm
Answer:
4.9 cm
Step-by-step explanation:
To solve this problem you would use the power of a point formula where two chords intersect in the interior of a circle. We get the equation:
7 * 7 = 10 *x
49 = 10x
x = 4.9 cm
Answer:
x = 4
Step-by-step explanation:
the first line (7cm and 7 cm) are the diameter. You add both numbers to get the diameter which would be 14. Then then next line (10 cm and x) would be the diameter as well. You can create an equation for this (10 + x = 14).
Subtract 14-10 and you get 4. Therefore x = 4

Quantity demanded is 200 units when the unit price is set at $90. The quantity demanded is 1200 units when the unit price is $40. Find the demand equation
Answer:
[tex]Q_n=(2000)-(20)P_n[/tex]
Step-by-step explanation:
From the question we are told that:
Initial Quantity demanded Q_1= 200 units
Initial demand price [tex]P_1=\$90[/tex]
Final Quantity demanded [tex]Q_2= 1200 units[/tex]
Final demand price [tex]P_2=\$40[/tex]
Generally the Demand Equation is mathematically given by
[tex]Q_n=a-bP_n[/tex]
Where
a=Other factors affecting price
b=Slope of the demand curve
Therefore
[tex]Q_1=a-bP_1[/tex]
[tex]200=a-b(90)[/tex]
[tex]Q_2=a-bP_2[/tex]
[tex]1200=a-b(40)[/tex]
Comparing both above equations
[tex]a=2000[/tex]
[tex]b=20[/tex]
Therefore the Demand Equation is mathematically given by
[tex]Q_n=(2000)-(20)P_n[/tex]

Find the area of the triangle. Enter your answer in the box. An obtuse triangle. The base of the triangle is fourteen millimeters. The long side of the triangle is twenty-seven millimeters. The height of the triangle is twelve millimeters.
Answer: [tex]84\ mm^2[/tex]
Step-by-step explanation:
Given
The long side of a triangle is 27 mm
The length of the base is 14 mm
height of the triangle is 12 mm
The area of a triangle is given by
[tex]\Rightarrow \dfrac{1}{2}\times \text{base}\times \text{height}[/tex]
Insert the values
[tex]\Rightarrow \dfrac{1}{2}\times 14\times 12\\\\\Rightarrow 84\ mm^2[/tex]
Thus, the area of the triangle is [tex]84\ mm^2[/tex]
Which expression has a value that is less than the base of that expression? A. 2^3 B. (5/6)^2 C. 3^1 D. 4^4
Answer:
B. (5/6)^2
Step-by-step explanation:
A. 2^3
= 2 × 2 × 2
= 8
The base is 2
Therefore, the expression is greater than the base
B. (5/6)^2
= 5/6 × 5/6
= 5*5 / 6*6
= 25/36
Base = 5/6 = 0.833
Expression =25/36 = 0.694
Therefore, the expression is less than the base
C. 3^1
= 3
The base is 3
Therefore, the expression is equal to the base
D. 4^4
= 4 * 4 * 4 * 4
= 256
The base is 4
Therefore, the expression is greater than the base
The correct answer is B. (5/6)^2

Step-by-step explanation:

In the figure, AB || DC and AD || BC. To prove that AB = CD, one must first show that
AABC-ACDA.
Which theorem or postulate can be used to justify AABC - ACDA?
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral, obtuse, acute and right angled triangles.
Two triangles are said to be congruent if all the corresponding sides and angles of both triangles are equal. Congruent triangles have the same size and shape.
Given that AB || DC and AD || BC, therefore:
∠DCA = ∠BAC (alternate angles are equal)
∠DAC = ∠BCA (alternate angles are equal)
AC ≈ AC
Therefore from triangle ABC and triangle CDA, since ∠DCA = ∠BAC, ∠DAC = ∠BCA and AC ≈ AC, hence both triangles are congruent by Ange-side-angle congruence theorem.
Therefore AB = CD
Answer:
the answer is AB is equal to CD

Rearrange 3x - 6y = -2 to the form y=mx + c
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
Answer:
y = 1/2x - 1/3
Step-by-step explanation:
subtract 3x from each side first to get:
-6y = -3x - 2
divide each side by -6 to get:
y = 3/6x - 2/6
simplify:
y = 1/2x + 1/3

the number 3.5 is...
============================================================
Explanation:
In your studies so far, every number you encounter is a real number. This changes when your teacher will introduce complex and imaginary numbers later on down the road. So 3.5 is a real number. A real number is essentially any number we can express as a decimal value (whether the decimal terminates, or goes on forever).
The number 3.5 is also rational because we can express it as a ratio of two integers, aka a fraction of two integers. Specifically, we can say 3.5 = 35/10 = 7/2.
The number 3.5 being rational would automatically rule out "irrational", since "irrational" means "not rational". The number 3.5 isn't an integer either. It would need to be either a positive whole number, negative whole number, or zero for it to be an integer. We rule out "natural number" for similar reasoning that we ruled out "integer".

Option DStep-by-step explanation:
[tex]( \frac{ - 8}{5} \times \frac{7}{4} )[/tex]
[tex] = \frac{ - 2}{5} \times \frac{7}{1} [/tex]
[tex] = \frac{ - 14}{5} [/tex]
As we know that,
The additive inverse of a number , is the number that, when added to it yields zero.
Since,
-14 + 14 = 0
Then,
[tex] \frac{ - 14}{5} + \frac{14}{5} = \frac{ - 14 + 14}{5} [/tex]
[tex] = \frac{0}{5} = 0[/tex]
Hence,
Option D is correct.

Answer:
14400 boxes
Step-by-step explanation:
After looking at this question you would first see that it is looking for how many cuboids can fit into the container. That would mean that the final equation should be the volume of container divided by the volume of the cuboid.
First, we can find the volume of the container. Keep in mind that the volume of a rectangular prism is V=Bh (which means area of the base times the height)
For the base we would do (600)(200) which is 120000
Next, the height is 300, so we would times that by 120000 (which is 36000000)
Moving on to the cuboid!
We would do the same process, but with smaller units.
(same equation) V=Bh
B= (50)(20)
=100
(100)(25)=2500
Lastly, like mentioned in the beginning, take the volume of the container and divide by the volume of the cuboid.
36000000/2500=14400
Therefore, 14400 boxes can fit into this container!
Hope this helps! :)
Answer:
Step-by-step explanation:
so they made the boxes fit perfectly into the container.. as they are.
notice that each of the dimensions of the box fit perfectly into the dimensions of the container.
length container of 600 / length of box 50=12
width of container of 200 / width of box 20 = 10
height of container of 300 / heigth of box 25 = 12
now just multiply those 3 answers
12 * 10 * 12 = 1440 boxes :)
BTW ( by the way ) I can see by what you have erased you did do the
300 ÷25 =12 correctly , (300/25), and the
200÷20 = 10 correctly, (200/20) but the
600÷50 = 20 was not correct. You can check this in your head really quickly by just multiplying 50*20 = 1000 , now you know that's not right, so then do 50*10=500 , that's close, hun, now just add 2 more 50s for a total of 600 and 12 , 50s :) see??
