One hexagonal prism has dimensions that are triple the dimensions of a similar hexagonal prism. If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
4.75 cm3
14.25 cm3
42.75 cm3
128.25 cm3
Answer:
128.25 cm³
Step-by-step explanation:
Volume of an hexagonal prism:
The volume of an hexagonal prism is given by:
[tex]V = \frac{3\sqrt{3} a^2h}{2}[/tex]
In which a and h are the dimensions.
Triple the dimensions
This means that the volume will be multiplied by 3^3, 27(as there are 3 terms which are dependent of the dimensions, a² and h).
If the volume of the smaller prism is 4.75 cm3, what is the volume of the larger prism?
27*4.75 = 128.25 cm³
128.25 cm³ is the answer
Answer:
128.25 cm3

The National Sleep Foundation recommends that teenagers aged 14 to 17 years old get at least 8 hours of sleep
per night for proper health and wellness.
A statistics class at a large high school suspects that students at their school are getting less than 8 hours of
sleep on average. To test their theory, they randomly sample 42 of these students and ask them how many hours
of sleep they get per night. The mean from the sample is 2 = 7.5 hours.
Here's their alternative hypothesis:
H : The average amount of sleep students at their school get per night is...
What is an appropriate ending to their alternative hypothesis?
Answer:
Less than 8 hours

If the value of a in the quadratic function f(x) = ax2 + b3 + cis , the function will:
open down and have a maximum
open down and have a minimum
open up and have a minimum
open up and have a maximum
If the value of a in the quadratic function f(x) = ax² + bx + c is 1/2, the function will: C. open up and have a minimum.
What is the general form of a quadratic function?In Mathematics and Geometry, the general form of a quadratic function can be modeled and represented by using the following quadratic equation;
y = ax² + bx + c
Where:
a and b represents the coefficients of the first and second term in the quadratic function.c represents the constant term.Since the leading coefficient (value of a) in the given quadratic function f(x) = ax² + bx + c is positive 1/2, we can logically deduce that the parabola would open upward. Also, the value of the quadratic function f(x) would be minimum.

What is the perimeter?
meters
Answer: 20+21+20+21=40+42=82
Step-by-step explanation:
Add up the sides
Multiply by 2
Try:
20+21=41
Multiply by 2:82
Answer:
82 meters
Step-by-step explanation:
to get the perimeter of a rectangle or square you have to add the lengths of all the four sides
P=20+20+21+21
P=2x20+2x21
P=2x(20+21)
P=2x41
P=82

5x + y = 27
- 10x + 7y = -36
what is the x-coordinate?
Answer: Y = 2 X = 5
Step-by-step explanation:
You would get this answer because 5x + y =27 then you would replace the x with 5 and you get 25 then if you turn y into 2 you get 27 which is what you are looking for same for the other problem hope this helps have a good day
Answer:
The answer is x=5

π/2
Answer:
tan*=sin*/cos*
sin*=1-(0.57)^2
sin*=0.6751
tan*=0.57/0.6751
=0.844
Help please !!! Need help
Answer:
234
Step-by-step explanation:
From the given information :
The 4th term, a4
a1 = 3
a2 = 4(a1) + 2
a2 = 4(3) + 2 = 14
a3 = 4(a2) + 2
a3 = 4(14) + 2
a3 = 58
a4 = 4a3 + 2
a4 = 4(58) + 2
a4 = 232 + 2
a4 = 234

because the formula for the triangle is 1/2×b×h
and the formula for the rectangle nos l×w and then add those.
Answer:
A = 60yd
Step-by-step explanation:
First "separate" the rectangle and the triangle in your head.
Now calculate the area of the rectangle and then the area of the triangle.
Rectangle: 6*8 = 48
Triangle: (6*4)/2 = 24/2 = 12
Now we add them together:
48 + 12 = 60yd

Ms. Strickland is practicing the piano for an upcoming recital. The table list the number of minutes she practiced in the past few weeks.
a. What is the median number of minutes she practiced?
b.What is the range of the data?
c.What is the mean number of minutes that she practiced?
Answer:
a. 20
b. 32
c. 20.6
Step-by-step explanation:
Median is the middle number- so put the numbers in order from least to greatest, and find the middle number
8, 10, 10, 15, 15, 20, 20, 20, 25, 25, 25, 35, 40
Median is 20
the range is the difference between the largest and the smallest value- 40-8 is 32
Mean is the average- add all the values and divide by the total number of values (13)
268 minutes divided by 13 days
mean is about 20.6 minutes

You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path.
a. Write a rule for the sequence using centimeters. The initial height is given by the is term n = 1.
b. What height will the ball be at the top of the sixth path?
1) A(n) = 1.5 • (0.74)^x-1; 0.33cm
2)A(n) = 0.74 • (1.5)^x-1; 5.62cm
3) A(n) = 150•(0.74)^x-1; 33.29cm
4) A(n) = 150 • (74) ^x-1; 332,850,993,600cm
Answer:
[tex](a)\ A(n) = 150 * (0.74)^{n-1[/tex]
[tex](b)\ A(6) = 33.29cm[/tex]
Step-by-step explanation:
Given
[tex]a = 1.5[/tex] --- initial
[tex]b = 74\%[/tex] --- rate
Solving (a): The rule of the sequence
First convert [tex]a = 1.5[/tex] to centimeters
[tex]a = 1.5 * 100[/tex]
[tex]a = 150[/tex]
The equation is then calculated using the following geometric progression formula
[tex]A(n) = ab^{n-1}[/tex]
This gives:
[tex]A(n) = 150 * (74\%)^{n-1}[/tex]
Express percentage as decimal
[tex]A(n) = 150 * (0.74)^{n-1[/tex]
Solving (b): The height on the 6th path
This implies that:
[tex]n = 6[/tex]
So, we have:
[tex]A(6) = 150 * (0.74)^{6-1[/tex]
[tex]A(6) = 150 * (0.74)^5[/tex]
[tex]A(6) = 150 * 0.222[/tex]
[tex]A(6) = 33.3cm[/tex]
