1. 3x + 9 = 12x + 36
x=

Answers

Answer:

x = -3

Step-by-step explanation:

3x + 9 = 12x + 36 (rewrite)

3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9

3x - 12x = 36 - 9 (collect like terms)

-9x = 36 - 9 ( substract)

-9x = 27 (divide both sides for the answer)

-9       -9

x = -3

A cylinderical container of height 28cm and diameter 18cm is filled with water. The water is then poured into another container with a rectangular base 27cm and width 11cm. Calculate the depth of the water in the container ( take π=22/7)

Answers

Answer:

h = 24 cm

Step-by-step explanation:

volume of water in the cylinder = volume of water in the rectangular base container

But ,

volume of cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

where:  is the radius and h is the height.

volume of cuboid = length x width x height

                             = l x w x h

So that;

[tex]\pi[/tex][tex]r^{2}[/tex]h = l x w x h

But, r = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, [tex]\pi[/tex] = [tex]\frac{22}{7}[/tex].

Thus,

[tex]\frac{22}{7}[/tex] x [tex](9)^{2}[/tex] x 28 = 27 x 11 x h

[tex]\frac{22}{7}[/tex] x 81 x 28 = 27 x 11 x h

7128 = 297h

h = [tex]\frac{7128}{297}[/tex]

  = 24

h = 24 cm

The depth of the water in the container is 24 cm.  

Here is a list of numbers:
-16, -20, -10, 1, -10, 5, 0 ,8 ,2 ,-7
State the median.

Answers

Answer:

-3.5

Step-by-step explanation:First you need to order the numbers so the numbers ordered would be -20,-16,-10-,10-,7,0,1,2,5,8 the median is finding the middle number in a list so you would cross of the end numbers until you are left -7 and 0 you then find the mid point of these two numbers which is -3.5 so that would be the answer.

Answer:

The median is -3.5

Step-by-step explanation:

hope this helps

-16, -20, -10, 1, -10, 5, 0 ,8 ,2 ,-7

Arrange the number in numerical order.

-20,-16,-10,-10,-7,0,1,2,5,8

There's two number is the middle which is -7 and 0 all you have to do is add them together and divide by 2.

-7+0= -7÷2=-3.5

When converting a decimal to a fraction, the digits to the right of the decimal point become the _____
of the fraction.

Answers

Answer:

numerator

Step-by-step explanation:

it becomes the numerator because however many places over the numbers to the decimals are is the amount if its in like the 10th 100th 1000th and so on. But if there is a one or more to the left side of the decimal it becomes the whole number, so that leaves the numerator. So that is how the numerator is the answer.

Let u = ⟨–2, 6⟩, v = ⟨3, 2⟩, and w = ⟨–1, 4⟩. What is the magnitude and direction angle of 2(u + v) – 3w?

2.8; θ = 45.0°
6.4; θ = 38.7°
28.0; θ = 92.0°
41.0; θ = 51.3°

Answers

u = ⟨-2, 6⟩

v = ⟨3, 2⟩

w = ⟨-1, 4⟩

u + v = ⟨-2, 6⟩ + ⟨3, 2⟩

u + v = ⟨-2 + 3, 6 + 2⟩

u + v = ⟨1, 8⟩

2 (u + v) = 2 ⟨-1, 8⟩

2 (u + v) = ⟨2 • 1, 2 • 8⟩

2 (u + v) = ⟨2, 16⟩

-3 w = -3 ⟨-1, 4⟩

-3 w = ⟨-3 • (-1), -3 • 4⟩

-3 w = ⟨3, -12⟩

2 (u + v) - 3 w = 2 (u + v) + (-3 w)

2 (u + v) - 3 w = ⟨2, 16⟩ + ⟨3, -12⟩

2 (u + v) - 3 w = ⟨2 + 3, 16 + (-12)⟩

2 (u + v) - 3 w = ⟨5, 4⟩

Then the magnitude of this vector is

||2 (u + v) - 3 w|| = √(5² + 4²) = √41 ≈ 6.403

so the second choice is correct.

B) 6.4; θ = 38.7°
