Answer:
Volume of cone = 72 ft³
Step-by-step explanation:
diameter = 6ft
radius = 3ft
height = 8ft
Volume of a cone = [tex]\frac{\pi r^2h}{3}[/tex]
V = (3 × 3 × 3 × 8)/3
V = 72 ft³
Answer:
V ≈ 72 ft³
Step-by-step explanation:
Given that volume (V) is calculated using
V = [tex]\frac{\pi r^2h}{3}[/tex] ( r is the base radius and h the height )
Here diameter d = 6 then r = 6 ÷ 2 = 3 and h = 8 , then
V = [tex]\frac{3(3^2)(8)}{3}[/tex] ( cancel 3 on numerator/ denominator )
= 9 × 8
= 72 ft³

At the city museum, child admission is $5.30 and adult admission is $9.20. On Monday, 121 tickets were sold for a total sales of $836.30.
How many adult tickets were sold that day?
Answers
Answer:
50 adult tickets were sold that day.
Step-by-step explanation:
Child ticket is $5.30Adult ticket is $9.20Total amount of ticket sold is 121, for $836.30We will use "c" to represent child ticket and "a" to represent adult ticket
Using these info, we can make a system of equations:
[tex]\left \{ {{9.2a + 5.3c = 836.3} \atop {a + c = 121}} \right.[/tex]
Solve the system of equations using substitution.
a + c = 121
c = 121 - a
9.2a + 5.3 (121 -a) = 836.3
9.2a + 641.3 - 5.3a = 836.3
3.9a = 195
a = 50
50 adult tickets were sold that day.
distinguish between rote and rational counting
Answers
Answer: There is a difference between rote counting and rational counting. Rote counting involves the memorization of numbers. Rational counting tells children "how many there are." For children to count rationally, they need to demonstrate one-to-one correspondence.

A doughnut shop wants to determine if there is a difference in donut sales at different times of the day and for different types of doughnuts. They are open in the morning, afternoon, and night, and offer the following flavors: vanilla, chocolate, red velvet, and marbled. There were a total of 48 sales recorded. The shop conducted a two-way ANOVA test and found an F test statistic for Flavor of 14.87. What would be the numerator degree of freedom for the F test statistic to determine if the factor flavor was significant
Answers
Solution :
Let
[tex]$k_1$[/tex] = number of levels for the factors 'flavors' = 4
(4 levels vanilla, chocolate, red velvet and marbled)
The degree of freedom for the factor 'flavors' = [tex]$k_1$[/tex] - 1
= 4 - 1
= 3
Now defining the F test statistics for testing the significance of the factors, 'flavors' :
F test statics = [tex]$=\frac{Ms\text{ (factor falvor)}}{Ms \text{ (errors)}}$[/tex] , Ms = mean square
where F = [tex]$F_{k_1-1}$[/tex], error df.
Thus the numerator degrees of the freedom for the F test statistics to determine if the factor flavor was significant is = [tex]$k_1$[/tex] - 1
= 4 - 1
= 3

DeVondrea stacked 2
quarters and a nickel on top
of each other. What is the
thickness of the stack of
coins?
Answers
Answer:
Step-by-step explanation:
Number of nickels = $1 * 1 nickel/$0.05 = 20 nickels
Thickness of 20 nickels = 20 nickels * 1.95 mm = 39 mm
Let's do the same for the quarters. Each quarter is worth $0.25.
Number of quarters = $1 * 1 quarter/$0.25 = 4 quarters
Thickness of 4 quarters = 4 quarters * 1.75 mm = 7 mm
Find the ratio of the two:
39 mm/7 mm = 5.57

Step-by-step explanation:
The figure is comprised of a semicircle, and 2 rectangles
Area of semicircle = 1/2(3.14)4^2 = 25.12
Area of rectangle with length of 9 and width of 7 = 7(9) = 63
Area of rectangle with length of 14 and width of 6 = 6(14) = 84
Total area = 25.12 + 63 + 84 = 172.12 sq in
Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 4x^2-8x-3
Answers
Answer:
x = 1 and vertex = (1, - 7 )
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
The the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = 4x² - 8x - 3 ← is in standard form
with a = 4, b = - 8 , then
x = - [tex]\frac{-8}{8}[/tex] = 1
That is equation of axis of symmetry is x = 1
Substitute x = 1 into the function for y- coordinate of vertex
y = 4(1)² - 8(1) - 3 = 4 - 8 - 3 = - 7
vertex = (1, - 7 )

Resale Value Garland Mills purchased a certain piece of machinery 2 years ago for $500,000. Its present resale value is $420,000. Assuming that the machine's resale value decreases exponentially, what will it be (in dollars) 4 years from now? (Round your answer to the nearest dollar.)
Answers
Answer:
260,000
Step-by-step explanation:
The value decreases by 40,000 per year (500000-42000/2 years) the value will decrease by 240000 in six (4 years plus 2 years already passed) years. 6 x 40,000 =240000
So, the value should be 260,000 (500000-240000)
Or
year 1 500000-40000=460000
year 2 460000-40000=420000
year 3 420000-40000=380000
year 4 380000-40000=340000
year 5 340000-40000=300000
year 6 300000-40000=260000
The machine's resale value Garland Mills purchased in 4 years from now will be; $353,049
What is the future value amount?
We are told that the machines present resale value is $420000. Now formula for future value is;
Future value = present value * exp(cx)
Thus;
$420,000 = $500,000 * exp(2c)
420000/500000 = exp(4c)
2c = In(420000/500000)
c = -0.087
Future value = present value * exp(cx)
Future value = $500,000 * exp(-0.087 * 4)
Future value = $353,049
Therefore, the machine's resale value in 4 years from now will be $353,049
