can be used to find the height of the cone.
Answers
Answer:
A,c,d
Step-by-step explanation:
The solution is Option A.
If the volume is 47 cm³ , then the height of the cone is approximately 5 cm and volume of cone is given by ( 1/3 ) πr²h
What is a Cone?
A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.
The volume of a cone is given by the equation
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
Given data ,
Let the radius of the cone be = r
Now , the value of r = 3 cm
So , the equation will be
The volume of the cone is given by the formula ,
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
a)
If the volume is 47 cm³, then the height of the cone is approximately 5 cm
So , substitute the values in the equation , we get
Volume of Cone = 47 cm³
So ,
( 1/3 ) πr²h = 47 cm³
Radius of cone r = 3 cm
Height of cone h = 5 cm
( 1/3 ) πr²h = 47 cm³
( 1/3 ) x 3.14 x 3 x 3 x 5 = 47
3.14 x 15 = 47
47 = 47
Therefore , the solution is true
Hence , If the volume is 47 cm³, then the height of the cone is approximately 5 cm and the volume of cone is given by ( 1/3 ) πr²h

Solve system by elimination
9x + 3y = 24
10x - 2y = 0
Answers
Answer:
(1, 5 )
Step-by-step explanation:
Given the 2 equations
9x + 3y = 24 → (1)
10x - 2y = 0 → (2)
Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term
18x + 6y = 48 → (3)
30x - 6y = 0 → (4)
Add (3) and (4) term by term to eliminate y
48x + 0 = 48
48x = 48 ( divide both sides by 48 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (1)
9(1) + 3y = 24
9 + 3y = 24 ( subtract 9 from both sides )
3y = 15 ( divide both sides by 3 )
y = 5
solution is (1, 5 )
Which equation could be used to solve for the length of side c, given a = 5, b = 12, and C = 72°?
Answers
Answer:
i had this question before
Step-by-step explanation:
c^2=a^2+b^2-2abcos(c)
c=sqrt(a^2+b^2-2abcos(c))
c=sqrt((5)^2+(12)^2-2(5)(12)cos(72))
c=sqrt(25+144-120cos(72))
c=sqrt(169-120cos(72))
c=sqrt(169-37.08)
c=sqrt(131.92)
c=11.49

C. g^{-1}[/tex](x)=[tex]\frac{10-x}{2}[/tex]
D. g^{-1}[/tex](x)=[tex]-4+\frac{1}{3}x[/tex]
Answers
Answer:
Step-by-step explanation:
Replace g(x) with y, then switch the x and y variables:
[tex]x=\frac{-5y+5}{2}[/tex]
Solve for the new y value, multiply by 2:
[tex]2x=-5y+5[/tex]
Subtract 5 on both sides:
[tex]2x-5=-5y[/tex]
Divide by -5 on both sides:
[tex]-\frac{2x-5}{5} =y[/tex]
Distribute the negative sign and rearrange:
[tex]\frac{-2x+5}{5} =\frac{5-2x}{5} =g^-^1(x)[/tex]
Answer:
A. g⁻¹(x) = (5 - 2x)/5Step-by-step explanation:

x = (-5y + 5) /22x = -5y + 55y = -2x + 5y = (-2x + 5)/5y = (5 - 2x)/5Replace y with g⁻¹(x)

On day 5, the biologist counted 16 Chinook. If the ratio of Chinook to Steelhead remained the same as on the previous four days, how many Steelhead should the biologist expect to count on day 5? Record your answer below. *
Captionless Image
Answers
Answer:
The answer is 40
Step-by-step explanation:
He expects to count #####################################
There are 12 Steelhead should the biologist expect to count on day 5.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The ratio of Chinook to Steelhead on the first four days is 4:10.
If this ratio remained the same on day 5, then we can expect the biologist to count of the salmon as Chinook.
On day 5, the biologist counted 16 Chinook,
Let x Steelhead would be the biologist expected to count on day 5.
As per the given question, the required solution would be as:
4/10 = 16/x
x = 16 × 10 / 4
x = 160/4
x = 40
Hence, there should be 40 Steelhead.
