Mathematics
1 answer:
Fed [463]1 year ago
4 0

Answer:

Step-by-step explanation:

1) Parallelepiped

<em>We need to find its surface area minus the area of the base and the base of the cylinder above.</em>

<em>2 (9) (2.4) = </em><em>43.2</em>

<em>2 (5) (2.4) = </em><em>24</em>

<em>4pi = Area of the base of the cylinder</em>

<em>45 - 4pi </em><em>= Area of the base of the parallelepiped minus covered region.</em>

<em>Surface needed = </em><em>112.2 - 4pi</em>

<em />

<em>2) Cylinder</em>

<em />

<em>We need to find its surface area minus the area of the base.</em>

<em>2 (pi) (2) (3) = 12pi </em>

<em>pi (4) = 4pi</em>

<em>Surface needed = </em><em>16pi</em>

<em></em>

<em>Total surafec needed:  </em>(112.2 - 4pi) + 16pi = 112.2 + 12pi

(This is solved in 'pi' terms)

If this helped, I'd like to have a brainliest. Have a nice day!!

7. Marco is making beaded bracelets. Each
stiks02 [169]

One way to find the least common multiple of two numbers is to first list the prime factors of each number.

8 = 2 x 2 x 2

Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

2: three occurrences

3: one occurrence

So, our LCM should be

2 x 2 x 2 x 3 = 24.

So, Marco can buy, at the very least, 24 beads of each color to have equal colors of beads.

x=\frac{-x}{2}  put in equ (1)

f(x)=-4x+1

f(\frac{-x}{2} )  =-4(\frac{-x}{2})+1

900% of it is 450 ?<br><br> please help with this
charle [14.2K]
900% of 450=4050

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 450 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 450 is 100%, so we can write it down as 450=100%.
4. We know, that x is 900% of the output value, so we can write it down as x=900%.
5. Now we have two simple equations:
1) 450=100%
2) x=900%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
450/x=100%/900%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 900% of 450

450/x=100/900
(450/x)*x=(100/900)*x - we multiply both sides of the equation by x
450=0.111111111111*x - we divide both sides of the equation by (0.111111111111) to get x
450/0.111111111111=x
4050=x

nalin [4]

Answer:

x=2/3, x=3/2

Step-by-step explanation:

6x^2-13x=-6

6x^2-13x+6=0

6x^2-4x-9x+6=0

2x*(3x-2)-3(3x-2)=0

(3x-2)8(2x-3)=0

3x-2=0

2x-3=0

x=2/3

x=3/2
