a solid metal cone with radius of base 12 cm and height 24 cm is melted to form spherical solid balls of diameter 6 cm each. Find the number of the balls thus formed
Answer:
32 solid balls are formed.
Step-by-step explanation:
Let suppose that volume of the cone is equal to the total volume of balls, of which we derive the following formula:
[tex]\frac{1}{3}\cdot \pi\cdot R^{2}\cdot h = \frac{1}{6}\cdot \pi \cdot n \cdot D^{3}[/tex] (1)
Where:
[tex]R[/tex] - Radius of the base of cone, measured in centimeters.
[tex]h[/tex] - Height of cone, measured in centimeters.
[tex]D[/tex] - Diameter of sphere, measured in centimeters.
[tex]n[/tex] - Number of balls, no unit.
Then, we clear the number of balls:
[tex]2\cdot R^{2}\cdot h = n\cdot D^{3}[/tex]
[tex]n = \frac{2\cdot R^{2}\cdot h}{D^{3}}[/tex]
If we know that [tex]R = 12\,cm[/tex], [tex]h = 24\,cm[/tex] and [tex]D = 6\,cm[/tex], then the number of balls is:
[tex]n = \frac{2\cdot (12\,cm)^{2}\cdot (24\,cm)}{(6\,cm)^{3}}[/tex]
[tex]n = 32[/tex]
32 solid balls are formed.

A double box-and-whisker plot represents the stock prices of Company A and Company B over a 30-day period. Both companies have a minimum price of $3 and a maximum price of $10. The median price for Company A is $6 and the median price for Company B is $9. Which company is more likely to have a symmetric box-and-whisker plot? Explain.
Answer:
company a
Step-by-step explanation:
It is probably company a because if you make a box and whisker plot in your head the median of 6 would be more in between 3 and 10 than 9. If the median were 9 it would probably be skewed. If 6 is near the middle the box and whisker plot would look more symmetric

The length of a rectangular prism is three times its width. The height is two times the length. If
its width is 2x^3 units, what is the volume of the prism?
Answer:
Step-by-step explanation:
Length = 3(2x^3) = 6x^3
Height = 2(6x^3) = 12x^3
Volume = (6x^3)(12x^3)(2x^3)=144x^9

Willa bought 5 tops that cost $72 after she applied a $20-off coupon. The tops all cost the same amount. Which equation can be used to find the cost in dollars of each top?
Answer:
14.40 dollars
Step-by-step explanation:
72 divided in 5
Substitute the values of x and y into the expression -3x^2+ 2y^2 + 5xy - 2y + 5x^2 - 3y^2. Match that values to one of the numbers.
1. x = 0.5, y = -1/10
2. x = -1, y = -3
3. x = ¾ , y = ⅖
4. x = 0, y = 2.5
5. x = √2, y = √2
6. x = 2, y = -1

The radius of a circular clock is 10.5 inches. Which measrement is closest to the circumference of the clock in inches
Answer:
65.9734457254 or 65.97
Step-by-step explanation:
c= pi x diameter
c= pi x (10.5 x 2)
c= pi x 21
= 65.9734457254
Answer:
66 in approx
Step-by-step explanation:
Given data
Radius= 10.5 inches
The circumference is given as
C= 2πr
Substitute
C=2*3.142*10.5
C=65.982
Hence the Circumference is 66 in approx

4. You buy a video game and pay for it with a $50 bil. Write an expression that can be used to find out how much change you shoud receive.
Answer:
[tex]\boxed{\textsf {\textbf{The amount returned by the shopkeeper is \$ 50 - x .}}}[/tex]
Step-by-step explanation:
Given that I buy a video game and pay $ 50 to the shopkeeper . And we need to find the expression how much change should I receive .
So , let us take that the video game costs x . There can be two cases .
★ Case 1 :-
When the cost of the product is same as the amount given . When the cost of the video game is $50 then the shopkeeper will give us no change .
[tex]\boxed{\red{\sf Returned\ change = \$ 0 }}[/tex]
[tex]\rule{200}2[/tex]
★ Case 2 :-
When the cost of the video game is less than $50 then the shopkeeper will return us some change that is equal to the difference if the amount given to shopkeeper and the cost of the video game .
If the cost of the video game is x , then the amount given to us by the the shopkeeper will be ,
[tex]\boxed{\red{\sf Returned\ change = \$ 50 - x }}[/tex]

In parallelogram ABCD, AB = (2x + 15) and 4C = x. Find x.
O55
O60
O15
O45
Answer:
x = 55
Step-by-step explanation:
ABCD is a paralellogram, m∠ABC = 2x + 15, m∠BCD = x
m∠ABC + m∠BCD = 180° (same side interior angles)
2x + 15 + x = 180
3x + 15 = 180 -15
3x = 165
x = 55

In the triangle XYZ, the measure of ∠XYZ is 104°, and the measure of ∠YZX is 19°. What is the measure of ∠ZXY?
Answer:
∠ZXY = 57°
Step-by-step explanation:
According to angle sum property of a triangle, sum of all the angles of the triangle is [tex]180[/tex]°.
In ΔXYZ,
∠XYZ + ∠YZX + ∠ZXY = 180°
Put ∠XYZ = 104°, ∠YZX = 19°
104° + 19° + ∠ZXY = 180°
123° + ∠ZXY = 180°
∠ZXY = 180° - 123°
∠ZXY = 57°
Therefore,
∠ZXY = 57°
Answer:
57
