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.

Which expression gives the measure of ABC?
A. 1/2(110° + 20°)
B. 1/2(110 -20°)
C. 110° - 20°
D. 110° + 20°
Answer:
A. 1/2(110° + 20°)
Step-by-step explanation:
[tex] \huge \orange{m\angle ABC} \pink{ = } \purple{\frac{1}{2} (110 \degree + 20 \degree)}[/tex]
Answer:
A
Step-by-step explanation:
The chord- chord angle ABC is half the sum of the arcs intercepted by the angle and its vertical angle, that is
∠ ABC = [tex]\frac{1}{2}[/tex] (110 + 20)° → A
= 0.5 × 130°
= 65°
A-line includes the points (8,9) and (9,1). What is its equation in point-slope form?
Answer:
[tex]y-(9)=(-8)(x-8)\\[/tex]
Step-by-step explanation:
[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]
Step one: Find the slope (m)
[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]
Step two: Plug your known values into the point-slope equation
[tex]m=-8\\y_1=9\\x_1=8\\[/tex]
Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(9)=(-8)(x-8)\\[/tex]
If you want to convert point-slope form to general form, isolate for y.
[tex]y-9=-8x+64\\y=-8x+73[/tex]

Answer:
I attached the graph below
Step-by-step explanation:
I started at the y-intercept, because it is where the line crosses the y-axis. Then, I used rise/run for the slope (-5/3) and went down 5 units and right 3 units. I connected the points to make the graph.
(14 plus 42)divided by 7plus4 to the 2power
Answer:
Given info in numersical form:

Use the regression calculator to compare the teams’ number of runs with their number of wins.
A 2-column table with 9 rows. Column 1 is labeled R with entries 808, 768, 655, 684, 637, 619, 613, 609, 563. Column 2 is labeled W with entries 93, 94, 66, 81, 86, 75, 61, 69, 55.
What is the y-intercept of the trend line, to the nearest hundredth?
Answer:
-23.21
there should be a two part for this and the answer would be D y= 0.15x - 23.21
Step-by-step explanation:
The line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
The data is given:
R(x) W(y)
808 93
768 94
655 66
684 81
637 86
619 75
613 61
609 69
563 55
The line of best fit can be written as:
y = mx + c
Here m is the slope of the line best fit and c is the y-intercept
Putting the values in the formula we get:
m = 0.15
c = -23.21
The line of best fit is:
y = 0.15x - 23.21
Thus, the line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.

Choose the method of pay that would result in the most earnings for one month on sales of 73,620
Answer:
Step-by-step explanation:
For option A: Earning = 0.06 x $73,620 = $4,417.20
For option B: Earning = $3,000 + 0.02 x $73,620 = $3,000 + $1,472.40 = $4,472.40
For option C: Earning = 0.04 x $50,000 + 0.09 x ($73,620 - $50,000) = $2,000 + 0.09 x $23,620 = $2,000 + $2,125.80 = $4,125.80
For option D: Earning = 0.05 x $35,000 + 0.07 x $(73,620 - 35,000) = $1,750 + 0.07 x $38,620 = $1,750 + $2,703.4 = $4,453.40
Therefore, the method that yields the most earning is monthly salary of $3,000 plus 2% commission on all sales .

Find the missing length
Answer: 15
Step-by-step explanation:
For this you will have to use pythagoras’ theorem.
The formula for the shorter side of this triangle is u²=c²-b² (or in this case u²=17²-8²).
17²=289
8²=64
The formula becomes u²=289-64 or u²=225
Then to find u on its own you have to square root 225.
The square root of 225 is 15.
Provide an appropriate response.

Find the nth term rule for the sequence: 20, 28, 36, 44
Answer:
a(n) = 12 + 8n
a1 = 20
a2 = 28 = 20 + 8
a3 = 36 = 20 + 8.2
a4 = 44 = 20 + 8.3
.......
=> this is a arithmetic with a1 = 20
d = 8
=> an = 20 + 8(n - 1) = 12 + 8n
