6(x +8)

Step-by-step explanation:

Factorising:

6x + 48

Take 6 as common, Therefore:

6(x +8)

Because:

6 * x = 6x

6 * 8 = 48

therefore:

6x + 48 = 6(x + 8)

Answer:

252 bags of maize

Step-by-step explanation:

From the question, we are told that a farmer harvested maize

In the year 2012 = 144 bags of maize

In the year 2013(following year) the harvest decreased in the ratio 3:4

This means

3:4 = 2013: 2012.

Where number of bags harvested in 2013 = unknown = x

3/4 = x/ 144

Cross multiply 4x = 3 × 144

x = 3 × 144/ 4

× = 108

This means 108 bags of maize was harvested in 2013

The total number of bags harvested is = 108 + 144

= 252 bags of maize.

Answer:

14

Step-by-step explanation:

Mathematically, the probability of drawing a pure cotton shirt = number of cotton shirts/Total number of shirts

Firstly , we are to calculate the number of cotton shirts after the addition of the new four

Thus;

Total number of shirts is now = 20+4 = 24

Let the number of cotton shirts be x after the addition

3/4 = x/24

24 * 3 = 4x

x = 72/4

x = 18

Now kindly recall that q became x only because we added 4 new extra cotton shirts

So the number of cotton shirts before the addition = 18-4 = 14

Answer:

8 th term

Step-by-step explanation:

Continuing the sequence from the last term given (term 4 )

a₅ = 0.5 × 28.5 - 2 = 14.25 - 2 = 12.25

a₆ = 0.5 × 12.25 - 2 = 6.125 - 2 = 4.125

a₇ = 0.5 × 4.125 - 2 = 2.125

a₈ = 0.5 × 2.125 - 2 = 1.0625 - 2 = - 0.9375 ← negative

The first term to be negative is term 8

Answer:

d. The two triangles are not congruent because dilation is not a rigid motion.

Step-by-step explanation:

Triangle ABC is dilated about the origin b a factor of 2. It is then reflected and translated to form Triangle XYZ.

The new triangle formed is not congruent to ABC because the image is not the same size as the pre-image. It is only rigid transformations that preserve length, however dilation is not a rigid transformation.

Answer:

The transformation is

reflection in the x axis

That's ( x , - y)

Hey! I am not stealing points, but pls complete your question. Which number line are you asking about? Where is the number line image?

Also, where is the option A?

Pls complete your question.

Answer:

Either £16 or £26.32 depending on what you meant in the question

Step-by-step explanation:

I'm going to answer the question in 2 ways, since I'm not sure if you mean £14 or 14%

If its £14, then the original price is 30-14 = £16

If its 14% then that means after the increase, the shirt will be 100%+14% of the original price or 114% of the original price.

This means that

£30 = 114%

To make it easier, reduce the 114% to 1 %

1% = 30/114

1% = £0.26316

100% = £26.32 (rounded to 2 decimal places)

Therefore the original price was £26.32

Answer:

The force pulling down the ramp is 374.6 lb

The force pressing on a line perpendicular to the ramp is 927.1 lb

Step-by-step explanation:

Given;

weight of boat (mg) , w = 1000 lb

angle of inclination of the ramp, θ = 22 degrees.

The force pulling the boat down, which is 'mg' has two components; the parallel component of the force which is pulling down the ramp and the vertical component of the force which is force pressing on a line perpendicular to the ramp

Parallel component of the force, F = mgsinθ

                                                      F = wsinθ

                                                      F = 1000 sin(22)

                                                      F = 1000 x 0.3746

                                                     F = 374.6 lb

Vertical component of the force which is force pressing on a line perpendicular to the ramp.

F = mgCosθ

F = wCosθ

F = 1000 x Cos(22)

F = 1000 x 0.9271

F = 927.1 lb

Answer:

A pentagon has 5 sides

Step-by-step explanation:

penta, often means 5.

Answer:

Step-by-step explanation:

We have 3 triangles here, all of them right triangles. The first one is the biggest one, triangle ABC. We know the side length AB = 14, and we know the hypotenuse length, BC = 30. We can use that, along with Pythagorean's Theorem, to solve for side length AC:

[tex]30^2=14^2+(AC)^2[/tex] and

[tex]900-196=(AC)^2[/tex] and

[tex]704=(AC)^2[/tex] so

[tex]AC=8\sqrt{11}[/tex]

We also have the smallest right triangle, triangle ABD, which has the base of x, our unknown. Side BD is our unknown, length x; side AD is the height, length y (also unknown); and side AB is the hypotenuse, length 14. We will come up with a system of equations for these 2 right triangles, using Pythagorean's Theorem, and then solve for x using substitution.

For the medium-sized triangle. triangle ADC, the hypotenuse is side AC with a measure of 8√11, the height is side AD length y, and the base is side DC length 30 - x. Putting those values into Pythagorean's Theorem:

[tex](30-x)^2+y^2=(8\sqrt{11})^2[/tex] and

[tex]900-60x+x^2+y^2=704[/tex] and

[tex]x^2-60x+y^2=-196[/tex]***  That's starred because it's important and we will come back to it.

The smallest triangle in Pythagorean's Theorem:

[tex]14^2=x^2+y^2[/tex] and solving that for y-squared:

[tex]y^2=196-x^2[/tex]. We will now sub that value for y-squared into the starred equation for y-squared and solve for x:

[tex]x^2-60x+196-x^2=-196[/tex] and

-60x = -392 so

x = 6.5

Step-by-step explanation:

twelve × 4=48 3×3=9 you then change the fourths and the thirds into twelfths. by rinsing the top and bottom by how much you need to, in this case 4×3 and 3×4. Now you've got 52/12+12/12, which equals 62/12 or 5 and 2/12

Answer: i) 12.5%       ii) 87.5%        iii) 23.4%

Step-by-step explanation:

There are two die, each with 8 sides so the total number of outcomes is 8²

i) Product is a prime number --> 2, 3, 5, 7

Since it is a prime we only have the option of one die being a 1 and the other being the prime number.

So possible successful outcomes is: (1, 2), (1, 3), (1, 5), (1, 7), (7, 1), (5, 1), (3, 1), and (2, 1) = 8 options.

[tex]\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{8}{8^2}=\dfrac{1}{8}=\large\boxed{12.5\%}[/tex]

ii) Not a perfect square.  Let's find the probability that it IS a perfect square and subtract that value from the total (64).

Product IS a perfect square --> 1, 4, 9, 16, 25, 36, 49, 64

Possible successful outcomes of a perfect square: (1, 1) (2, 2), (3, 3), (4, 4), (5, 5), (6, 6), (7, 7), (8, 8) = 8 options.

Product is NOT a perfect square = 64 - 8 = 56 options

[tex]\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{56}{8^2}=\dfrac{7}{8}=\large\boxed{87.5\%}[/tex]

iii) Product is a multiple of 5 --> 5, 10, 15, 20, ,25, 30, 35, 40,

Possible successful outcomes of a multiple of 5: (1, 5), (2, 5), (3, 5), (4, 5), (5, 5), (6, 5), (7,5), (8, 5), (5, 8), (5, 7), (5, 6), (5, 4), (5, 3), (5, 2), (5, 1) = 15 options

[tex]\dfrac{successful\ outcomes}{total\ possible\ outcomes}=\dfrac{15}{8^2}=\dfrac{15}{64}=\large\boxed{23.4\%}[/tex]

Answer:

The system of equations is consistent and independent

Step-by-step explanation:

Given system of equations :

[tex]y=x+4\\y= -x-4[/tex]

Consistent : For a two variable system of equations to be consistent the lines formed by the equations have to meet at some point or they have to be parallel.

Inconsistent :If the system of equations is not consistent then it is inconsistent.

Dependent:A dependent system of equations has infinite solutions

Independent :An independent system has a single solution.

Plot the lines on graph

y=x+4 --- Blue line

y=-x+4 ---- Green line

Refer the attached graph

The lines formed by the equations intersect at one point

So the lines are consistent

Now the given system of equations has single solution . So, it is independent

So, Option C is true

Hence The system of equations is consistent and independent
