We know that
[lateral area of a cone]=pi*r*l
where
l is the slant height
r is the radius
lateral area=pi*r*l---------> l=lateral area/(pi*r)-----> l=112*pi/(pi*8)---> l=14 cm
the answer is
14 cm
[lateral area of a cone]=pi*r*l
where
l is the slant height
r is the radius
lateral area=pi*r*l---------> l=lateral area/(pi*r)-----> l=112*pi/(pi*8)---> l=14 cm
the answer is
14 cm

Factor as far as possible 3u^4-4u^3 and 3u^7+12u^2
Solution 1
For the first one you can say:
u^3(3u - 4) and that's the answer because 3 is the biggest power that you can factor.
for the second one also you can say:
3u^2(u^5-4) and that's the answer. :)))
I hope this is helpful

Question
Manuela solved the equation 3 – 2|0.5x + 1.5| = 2 for one solution. Her work is shown below. 3 – 2|0.5x + 1.5| = 2 –2|0.5x + 1.5| = –1 |0.5x + 1.5| = 0.5 0.5x + 1.5 = 0.5 0.5x = –1 x = –2
Solution 1
3 – 2|0.5x + 1.5| = 2
3 – x – 3 = 2
-x = 2
x = 2
or
3 – 2|0.5x + 1.5| = 2
– 2|0.5x + 1.5| = 2 - 3
– x – 3 = -1
– x = -1 + 3
-x = 2
x = 2

Question
6 is 25% of what i need help on this problem
Solution 1
6 is 25% of 24. 6 times 4 = 24
Solution 2
100%/25% = 4. Since we know that 6 is 25% of a number, we can find what the number is (otherwise known as 100% of the number) by multiplying 6 by 4. 6*4= 24. 6 is 25% of 24.
Question
CDs and DVDs Solve by setting up a system of linear equations with 2 variables and 2 unknowns. CDs cost $5.96 more than DVDs at All Bets Are Off Electronics. How much would 6 CDs and 2 DVDs cost if 5 CDs and 2 DVDs cost $127.73?
Solution 1
The relationship between the total cost and the costs of CDs and DVDs are represented by a linear function.
The cost of 6 CDs and 2 DVDs is $147.68
Let:
From the question, we have:
Substitute in
Collect like terms
Divide both sides by 7
Substitute in
The cost of 6 CDs & 2 DVDs is represented as:
So, we have:
Hence, the cost of 6 CDs & 2 DVDs is $147.68

Solution 2
6 CDs and 2 DVDs would cost $147.68.
Let c be the cost of a CD and d be the cost of a DVD.
We know that c = d+5.96.
We also know that 5c+2d = 127.73.
Substituting our value of c from the first equation into the second one, we have
5(d+5.96)+2d = 127.73
Using the distributive property,
5*d+5*5.96+2d = 127.73
5d+29.80+2d = 127.73
Combining like terms,
7d+29.80 = 127.73
Subtract 29.80 from both sides:
7d+29.80-29.80=127.73-29.80
7d = 97.93
Divide both sides by 7:
7d/7 = 97.93/7
d = 13.99
c = d + 5.96 = 13.99+5.96 = 19.95
6 CDs and 2 DVDs would be
6(19.95)+2(13.99) = 147.68
Let c be the cost of a CD and d be the cost of a DVD.
We know that c = d+5.96.
We also know that 5c+2d = 127.73.
Substituting our value of c from the first equation into the second one, we have
5(d+5.96)+2d = 127.73
Using the distributive property,
5*d+5*5.96+2d = 127.73
5d+29.80+2d = 127.73
Combining like terms,
7d+29.80 = 127.73
Subtract 29.80 from both sides:
7d+29.80-29.80=127.73-29.80
7d = 97.93
Divide both sides by 7:
7d/7 = 97.93/7
d = 13.99
c = d + 5.96 = 13.99+5.96 = 19.95
6 CDs and 2 DVDs would be
6(19.95)+2(13.99) = 147.68
Question
Rectangle J'K'L'M' shown on the grid is the image of rectangle JKLM after transformation. The same transformation will be applied on trapezoid STUV. Rectangle JKLM is drawn on the grid with vertices J at negative 5, 1. K is at negative 5, 6. L is at negative 7, 6. M is at negative 7, 1. Rectangle J prime K prime L prime M prime is drawn with vertices at J prime 4, 4. K prime is at 4, 9. L prime is at 2, 9. M prime is at 2, 4. Trapezoid STUV is drawn with vertices at S is at 9, negative 6. T is at 9, negative 2. U is at 7, negative 2. V is at 6, negative 5. What will be the location of U' in the image trapezoid S'T'U'V'? (16, −2)
Solution 1
U' will be at (16, 1).
The transformation that maps JKLM to J'K'L'M' is a translation 9 units right and 3 units up.
The same transformation is applied to STUV; this means that U(7, -2) will be mapped to U'(7+9, -2+3) = U'(16, 1).

Question
A polyhedron has 10 faces and 24 edges. Use Euler's Formula to find the missing number of vertices.
Solution 1
Euler's Formula : V - E + F = 2
Given that F = 10 and E = 24
V - 24 + 10 = 2
V - 14 = 2
V = 16
Answer: Vertices = 16
Given that F = 10 and E = 24
V - 24 + 10 = 2
V - 14 = 2
V = 16
Answer: Vertices = 16
Solution 2
Hey user!!
your answer is here...
we know that Euler's formula = F + V - E = 2
given :-
faces = 10
verticies = ?
edges = 24
therefore F + V - E = 2
==> 10 + V - 24 = 2
==> -14 + V = 2
==> V = 2 + 14
==> V = 16
verification :-
= F + V - E
= 10 + 16 - 24
= 26 - 24
= 2
hence verified..
thus the no. of verticies of the polyhedron is 16.
cheers!!

Simplify the problem sqrt 245c^5
Solution 1
We have that
√[245c^5]-------> √245*√c^5
we know that
245-----> 5*7²
c^5---- c²*c²*c
so
√245-----> √[5*7²]----> 7√5
√c^5----> √[c²*c²*c]---> c²√c
√245*√c^5-----> [7√5]*[c²√c]----> 7c²√(5c)
the answer is
7c²√(5c)
√[245c^5]-------> √245*√c^5
we know that
245-----> 5*7²
c^5---- c²*c²*c
so
√245-----> √[5*7²]----> 7√5
√c^5----> √[c²*c²*c]---> c²√c
√245*√c^5-----> [7√5]*[c²√c]----> 7c²√(5c)
the answer is
7c²√(5c)
