Step-by-step explanation:
From the picture of a cone attached,
Radius of the circular top = r
Height of the cone = h
Slant height of the cone 'l' = 6
Area of the circular top of the cone with radius 'r' = πr²
Amount of space inside the cone = Volume of the cone = [tex]\frac{1}{2}\pi r^{2} h[/tex]
The amount of wrapper needed to cover the side of the ice cream cone, not including the circular top of the cone = πrl = πr(6 in.)
The vertical height 'h' of the cone when the cone is standing upright = [tex]\sqrt{6^2-r^2}[/tex]
[By Pythagoras theorem, l² = h² + r² ⇒ h = [tex]\sqrt{l^2-r^2}[/tex]]

Choose the two rectangular prisms that have a volume of 36 cm”.
= 1 cm3
A.
D.
B.
E.
C.
Answer:
B & D
Step-by-step explanation:
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
For (a):
[tex]Length = 3cm[/tex]
[tex]Width = 4cm[/tex]
[tex]Height = 5cm[/tex]
[tex]Volume = 3cm * 4cm * 5cm[/tex]
[tex]Volume = 60cm^3[/tex]
For (b):
[tex]Length = 3cm[/tex]
[tex]Width = 4cm[/tex]
[tex]Height = 3cm[/tex]
[tex]Volume = 3cm * 4cm * 3cm[/tex]
[tex]Volume = 36cm^3[/tex]
For (c):
[tex]Length = 4cm[/tex]
[tex]Width = 2cm[/tex]
[tex]Height = 2cm[/tex]
[tex]Volume = 4cm * 2cm * 2cm[/tex]
[tex]Volume = 16cm^3[/tex]
For (d):
[tex]Length = 2cm[/tex]
[tex]Width = 3cm[/tex]
[tex]Height = 6cm[/tex]
[tex]Volume = 2cm * 3cm * 6cm[/tex]
[tex]Volume = 36cm^3[/tex]
There's no need to check for (e)
Option b and d answers the question
Using the volume of a rectangular prism to examine the volumes of the prism, the two prisms with a volume of 36cm³ are B and D
Recall :
Volume of a rectanglular prism = Length × width × HeightPrism A :
Length = 3cm ; Height = 5cm ; Width = 4cmVolume = 3cm × 5cm × 4cm = 60 cm³
Prism B :
Length = 3cm ; Height = 3cm ; Width = 4cmVolume = 3cm × 3cm × 4cm = 36 cm³
Prism C :
Length = 4cm ; Height = 3cm ; Width = 2cmVolume = 4cm × 3cm × 2cm = 24 cm³
Prism D :
Length = 2cm ; Height = 6cm ; Width = 3cmVolume = 2cm × 6cm × 3cm = 36 cm³
Prism E :
Length = 3cm ; Height = 5cm ; Width = 4cmVolume = 4cm × 2cm × 2cm = 16 cm³
Hence, the two rectangular prisms with a volume of 36cm³ are B and D.

Write a linear equation that has a slope of 1/2 and a y-intercept at the origin.
Answer:
y=1/2x
Step-by-step explanation:
Slope intercept form is the most commonly used linear equation:
It goes like this:
[tex]y=mx+b[/tex]
In this equation, m is the slope and b is the y-intercept.
Your line has a slope of 1/2. So, your m-value is 1/2.
y=1/2x+b
B, your y-intercept, is at the origin.
The origin is the point (0,0).
So b, is 0 (y-intercept is the y-value when x is 0)
y=1/2x+0
=
y=1/2x
In the equation y=3/2x-4what are the slope and y-intercept?
Answer:
Slope:

A) 1 meter/3.25 feet = 15.2 meters/x feet
B) 1.6 kilometers/1 mile = x kilometers/25 miles
C) 0.926 meter/1 yard = 200 meters/x yards
D) 1 kilometers/0.6 mile = x kilometers/350 miles
Answer:
A) 49.4
B) 40
C) 0.00539
D)583.33
Step-by-step explanation:
A)
1 meter/3.25 feet = 15.2 meters/x feet
x feet * 1 meter = 15.2 meters* 3.25 feet
x = 15.2 meters* 3.25 feet/1 feet* meter
x = 49.4
B) 1.6 kilometers/1 mile = x kilometers/25 miles
multiplying both sides by 25 miles
(1.6 kilometers/1 mile )* 25 miles =( x kilometers/25 miles) * 25 miles
=> 40 kilometers = x kilometers
x = 40
C) 0.926 meter/1 yard = 200 meters/x yards
dividing both sides 200 meters
0.926 meter/(1 yard*200 meters) = 200 meters/(x yards *200 meters)
185.2 /1 yard = 1/ x yards
x yards = 1 yards/185.2
=> x = 0.00539
D) 1 kilometers/0.6 mile = x kilometers/350 miles
multiplying both sides by 350 miles
(1 kilometers/0.6 mile ) 350 miles= (x kilometers/350 miles) 350 miles
=> 583.33 kilometers = x kilometers
x = 583.33

Yulia observed a sound wave moving through a solid medium at four different temperatures, and she recorded observations about each one in the chart. A 2-column table with 4 rows. The first column labeled Wave has entries W, X, Y, Z. The second column labeled Temperature (degrees Celsius) has entries 15, 33, 12, 2. Which correctly ranks, from fastest to slowest, the time it will take one wavelength to pass a certain point? Wave X → Wave Y → Wave W → Wave Z Wave Z → Wave W → Wave Y → Wave X Wave X → Wave W → Wave Y → Wave Z Wave Z → Wave Y → Wave W → Wave X
Answer: C. Wave X, Wave W, Wave Y, Wave Z.
The option that ranks the time it will take one wavelength to pass a certain point from fastest to slowest is Wave X → Wave W → Wave Y → Wave Z.
Why is this the correct order?The speed at which sound waves will pass through a medium depends on the temperature of that medium.
The higher the temperature of a medium, the faster sound waves will pass through. This is why Wave X will pass through the fastest at 33°C while Wave W will pass through the second fastest at 15°C and so on.
In conclusion, option C is correct.

ОА.
50
OB.
96
O C.
100
OD.
200
Answer:
D. 200
Step-by-step explanation:
If you would like to solve 32% of a number is 64, you can calculate this using the following steps:
32% of a number is 64
32% * x = 64
32/100 * x = 64 /*100/32
x = 64 * 100 / 32
x = 200
Result: 32% of 200 is 64.

Step-by-step explanation:
[tex]f(1 \div 4) = {(1 \div 4)}^{2} + 2(1 \div 4) + 1 \\ = {625 \times 10}^{ - 4} + 0.5 + 1 \\ = 1.5 + 0.0625 \\ = 1.5625[/tex]
Answer:
25/16
Step-by-step explanation:
f(1/4) means that we're plugging in 1/4 for x in the given function.
Our function is:
f(x) = x² + 2x + 1
Plug 1/4 in for x:
f(1/4) = (1/4)² + 2 * (1/4) + 1 = 1/16 + 2/4 + 1 = 1/16 + 8/16 + 16/16 = 25/16
Thus, the answer is 25/16.

Hope it helps..plz mark as brainlist..if f(x)=2x^2 +3x what is f(9)
Answer:
f(9) = 189
Step-by-step explanation:
Plug 9 into x
f(9) = 2(9)^2 + 3(9)
f(9) = 2(81) + 27
f(9) = 162 + 27
Thus, f(9) = 189
Answer:
189
Step-by-step explanation:
f(x) = 2x^2 + 3x , f(9)
f(9) = 2(9)^2 + 3(9)
= 2(81) + 27
= 162 + 27
= 189
How much greater is the sum of the first 100 triangular numbers than the sum of the first 99 triangular numbers? Answer: It is bigger.
Answer:
First, a triangular number can be written as:
Tₙ = (n^2 + n)/2
where n is the number of our triangular number, n = 1 represents the first one, n = 2 represents the second one, etc.
The sum of the first 100 triangular numbers is:
S1 = (T₁ + T₂ + ... + T₉₉ + T₁₀₀)
The sum of the first 99 triangular numbers is:
S2 = (T₁ + T₂ + ... + T₉₉)
Then the difference will be:
D = S1 - S2 = (T₁ + T₂ + ... + T₉₉ + T₁₀₀) - (T₁ + T₂ + ... + T₉₉) = T₁₀₀
And we can find the value of T₁₀₀ if we use the equation for triangular numbers:
T₁₀₀ = (100^2 + 100)/2 = 5,050
