Answer:
The answer is C.
Step-by-step explanation:
I would simplify the expression first.
Equation: (6m^-1)^-3
You can get rid of n^0 because that equals 1.
Any expression raised to the power of -1 equals its reciprocal.
Equation: (6/m)^-3
Equation: (m/6)^3
Final Equation: m^3/216
Now, plug in 3.
(3)^3/216.
27/216 = 1/8

A 6 cm high cone has a volume of 128π cm3 What is its exact surface area?
A. 160π cm2
B. 96π cm2
C. 144π cm2
D. 104π cm2
Answer:
height [h]=6cm
Volume of cone =1/3 πr²h
128πcm³=1/3×π×r²×6
128×3/6=r²
r=√64
r=8cm
Now
slant height (l)=√{8²+6²}=10cm
again
.Total surface area :πrl+πr²=π×8(10+8)=144πcm²
its exact surface area is C. 144π cm²

If the diameter of the circle above is 16 mm, what is the area of the circle?
A.
16 mm2
B.
64 mm2
C.
8 mm2
D.
256 mm2
Answer:
64[tex]\pi[/tex] mm² or approximately 201.06 mm²
Step-by-step explanation:
If the diameter is 16 mm, the radius will be 8 mm.
Use the circle area formula, A = [tex]\pi[/tex]r², where r is the radius. Plug in 8 as r:
A = [tex]\pi[/tex]r²
A = [tex]\pi[/tex](8²)
A = 64[tex]\pi[/tex]
So, the area of the circle is 64[tex]\pi[/tex] mm² or approximately 201.06 mm²
If the diameter of the circle above is 16 mm, what is the area of the circle ?
Solution:-Diameter of the circle = 16 mm. (Given)
Radius (r) of the circle = 16/2 = 8 mm.
[tex] \bigstar [/tex] To Find the area of the circle.
Since we know,
[tex] \dag [/tex] Area of circle is πr².
So, Area of the circle = 3.14 × (8)²
Area of the circle = 3.14 × 8 × 8
Area of the circle = 200.96 = 201 mm².
The area of the circle is 201 mm². [Answer]Solve the system of equations x+2y=-16 and x+6y=-28 by combining the equations.
Answer:
x= -18 y=-5/3
Step-by-step explanation:
Answer:
x = -10
y = -3
Step-by-step explanation:
When combining the equations, we must ensure that one of the two variables will cancel out. The easiest way to do this will be to multiply one of the equations by -1, such that the x will cancel out once they are added together. This can be done with either equation, but I will do it for the first one.
This gives us the system:
[tex]\left \{ {{-x-2y=16} \atop {x+6y=-28}} \right.[/tex]
We can then add the two equations by combining each of the terms:
[tex](x - x) + (6y - 2y) = (-28 + 16)\\(0) + (4y) = (-12)\\4y = -12\\y = -3[/tex]
Now that we have the value for y, we substitute it back into any of the original equations and solve for x:
[tex]x + 2y = -16\\x + 2(-3) = -16\\x - 6 = -16\\x = -10[/tex]
To check our work, we substitute both x and y into the other original equation:
[tex]x + 6y = -28\\(-10) + 6(-3) = -28\\-10 - 18 = -28\\-28 = -28[/tex]

Solve for x.
2x2 + x = 10
Answer:
x = 2, x = -5/2
Step-by-step explanation:
2x² + x - 10 = 0
(2x + 5)(x - 2) = 0
2x + 5 = 0
2x = -5
x = -5/2
x - 2 = 0
x = 2
The top of a pie container is a circle. The radius of the pie is 8 inches and the radius of the container is 9 inches. What is the difference between the circumference of the container and the circumference of the pie in inches to the nearest tenth?
A : 3.1 inches
B 6.3 inches
C: 12.6 inches
D 25.1 inches
E 50.2 inches
Answer:
B. 6.3 inches.
Step-by-step explanation:
I'll use 2πr for both sides of this.
Pie:
2 * 3.14 * 8
16 * 3.14
50.24 inches for the pie
Container:
2 * 3.14 * 9
18 * 3.14
56.52 inches for the container
Difference:
56.52 - 50.24
6.28-inch difference, which rounds to 6.3 inches. B is our answer.

Problem A fruit stand has to decide what to charge for their produce. They need \$10$10dollar sign, 10 for 444 apples and 444 oranges. They also need \$12$12dollar sign, 12 for 666 apples and 666 oranges. We put this information into a system of linear equations.
Answer:
4a + 4b = 10
6a + 6b = 12
Step-by-step explanation:
Putting the equation in a system of linear equation :
We donate, apples and oranges using any preffered letter or alphabet
Let :
Apples = a ; oranges = b
4 apples and 4 oranges equals $10
4a + 4b = 10
6 Apples and 6 oranges equals $12
6a + 6b = 12
Hence, the system of linear equation :
4a + 4b = 10
6a + 6b = 12

Answer:
The height is 8 inches
Step-by-step explanation:
Well to find the volume of a cylinde like this, he formula is Base * height.
To find the base we need to find the area of the circle.
a=πr^2
The radius is 3 inches, 3^2=9
Since π is suppose to be 3.14 multiply
9*3.14= 28.26
We know that the cylinder can hold 231 cubic inches. So technically it can fill (x) 28.26 inches.
solve the equation
28.26x=231
Divide
231/28.26
The answer would be about 8 inches

Can you solve the surface area and the volume for the triangular prism? i need it now please
Surface Area = 96in³
To find the surface area of a triangular prism we can use the following equation

Checking for a perfect cube :

Trying to factor by pulling out :
3.2 Factoring: 2x3 - 5x2 + 2x - 7
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 2x - 7
Group 2: 2x3 - 5x2
Pull out from each group separately :
Group 1: (2x - 7) • (1)
Group 2: (2x - 5) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 2 and the Trailing Constant is -7.

There are 22,521 more people living in the suburbs of a city than in the city. If 17,245 people live in the city, how many people live in the suburbs?
Answer:
Number of people in the suburbs= 39,766
Step-by-step explanation:
Giving the following information:
22,521 more people are living in the suburbs of a city than in the city.
Number of people in the city= 17,245
To calculate the number of people that lives in the suburbs, we need to use the following formula:
Number of people in the suburbs= Number of people in the city + 22,521
Number of people in the suburbs= 17,245 + 22,521
Number of people in the suburbs= 39,766

kirans aunt is 15 years older than kiran. how old will kirans aunt be when kiran is 13? how old will kiran be when his aunt is 60 years old?
Answer:
When Kiran is 13, his aunt will be 28.
When Kiran's aunt is 60, he will be 45.
Step-by-step explanation:
Hope this helps!
Answer:
a) 28 (kiran's aunt when kiran is 13)
b) 45 (kiran when kiran's aunt is 60)
Step-by-step explanation:
first
let kiran's age be k
kiran's aunt= 15 + k
when kiran is 13, kiran's aunt is 15+13
15+13= 28
when kiran's aunt is 60;
15+k = kiran's age
60 = 15+ k
k = 60-15
k = 45
