ANSWER

6.6 ft

EXPLANATION

The section of the course will contain a 12 foot ladder leaning against a 10 foot wall.

Let us draw a diagram of the situation:

This situation forms the shape of a Right Angle Triangle.

x represents the distance of the bottom of the ladder from the wall.

We can find the value of x by using Pythagoras rule:

From the question:

hyp = 12 ft

opp = 10 ft

adj = x ft

So, we have that:

The wall should be 6.6 ft from the bottom of the ladder.

For  Multiplication:

For Division:

Addition combines numbers using the symbol '+' to create a sum. Adding 2 and 3 equals 5 (2 + 3 = 5). Subtraction finds the difference between two numbers. Subtraction subtracts with the symbol '-'. When you subtract 4 from 9, the difference is 5 (9 - 4 = 5).

Multiplication involves repeated addition or combining equal groups. The multiplication symbol is 'x' or '•'. E.g., 3 x 4 = 12. Division splits a number into parts or determines how many times one number is in another using '÷' or '/'. 12 ÷ 3 = 4.

Given the provided coordinates of the points, The shape that is formed is a parallelogram because the slopes of the opposite sides are same.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Divide the difference in elevation between two points by the distance between them to find the percent slope, then multiply the result by 100. The term "rise" refers to the difference in elevation between two sites. The run is the separation between the points. Percent slope is therefore equal to (rise / run) x 100.

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.

slope between (1,1) and (4,4),

m1 = 4-1/4-1 =3/3 =1

slope between (4,-2) and (7,1),

m2= 1+2/7-4 = 3/3 =1

m1=m2

similarly, slope between (1,1) and (4,-2),

m3= -2-1/4-1 = -3/3 =-1

slope between (7,1) and (4,4)

m4= 1-4/7-4 = -3/3 =-1

m3=m4

So, slopes of opposite sides are same that means they are parallel, The shape is parallelogram.

The required, Mmusi borrowed R3000 from Aggie as per the given conditions.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan.

Amount = Principal [1 + rate×time]

Let's call the amount Mmusi borrowed from Aggie "P".

After two years, he has to pay back
= P + P * 18% * 2
= P + 0.18 * P * 2
= P + 0.36P
= 1.36P

So if he has to pay back R4080, we can set up an equation to solve for P:

1.36P = 4080

To find P, we can divide both sides by 1.36:

P = 4080 / 1.36 = 3000

So Mmusi borrowed R3000 from Aggie.

Answer:

x=1

Step-by-step explanation:

2(5x + 8) = 6x + 20

Divide each side by 2

2/2(5x + 8) = 6x/2 + 20/2

5x+8 = 3x+10

Subtract 3x from each side

5x-3x +8 = 3x-3x+10

2x+8 = 10

Subtract 8 from each side

2x+8-8=10-8

2x=2

Divide by 2

2x/2 = 2/2

Answer:

x = -60

Step-by-step explanation:

Given the equation:

\( \displaystyle{0.1x - 5 = - 11}\)

Add both sides by 5

\( \displaystyle{0.1x - 5 + 5= - 11 + 5} \\ \\ \displaystyle{0.1x = - 6}\)

Multiply both sides by 10 to get rid of the decimal

\( \displaystyle{0.1x \times 10 = - 6 \times 10} \\ \\ \displaystyle{x= - 60}\)

Therefore, x = -60

Answer:

Step-by-step explanation:

0.1x − 5 = −11

0.1x = -11 + 5

0.1x = -6          multiply by 10 both sides

x = -60

--------------------------

0.1 x (- 60) - 5 = -11

-6 - 5 = -11

-11 = -11

The standard deviation of security B, the answer is option D, 18.75%.

Given that Security A and B have a covariance of 450%2,

Security A is estimated to have a variance of 900%2,

and the correlation between the two securities is 0.8.

We know that the covariance between Security A and B is given as;

Cov(A,B) = p(A,B)σAσB, where p(A,B)

is the correlation between A and B, σA is the standard deviation of A, and σB is the standard deviation of B.

Therefore, the standard deviation of Security B is given by;

σB = Cov(A,B)/[p(A,B)σA]

= (450%2)/[0.8 × (900%2)1/2]

= (450%2)/[0.8 × (900)1/2]%

≈ 18.75%.

Therefore, the answer is option D, 18.75%.

Answer:

\(y=-\frac{4}{3} x+2\)

Step-by-step explanation:

In order to write an equation that represents a line, you have to write it in Slope-Intercept Form.

Slope-Intercept Form: y = mx+b

Where b represents the Y-intercept

Where m represents the Slope

**********************************************

That's all you need to know about Slope-Intercept Form!

How do we get started?

Well first off, take a look at the graph and spot two points that are shown

The two points will be: (0, 2) and (3, -2)

Then use the two points to Solve for the Slope of the line!

m = slope

m = \(\frac{y2-y1}{x2-x1}\)       Second y - first y/ Second x - First x

m = \(\frac{-2-2}{3-0}\)        

m = \(\frac{-4}{3}\)           Turn the whole answer negative since there's a negative

m = \(-\frac{4}{3}\)           Final Answer

so the slope of the line is -4/3

Now we need to get the Y-intercept of the line!

Easy we don't need to solve just look how many units the graph goes up in y-axis?

2 units

so the y-intercept of the line is 2

Answer:

30.4

Step-by-step explanation:

17+28+32+35+59+20+19+33+30+31=304

304/10=30.4

Using the conceptual Formula, the sum of the squares is option (C) 422

To compute the standard deviation using the conceptual (deviation score) formula, we need to follow these steps:

Calculate the mean of the scores:

mean = (40 + 25 + 15 + 19 + 16) / 5 = 23

Calculate the deviation score for each score:

deviation score = score - mean

The deviation scores for each score are:

40 - 23 = 17

25 - 23 = 2

15 - 23 = -8

19 - 23 = -4

16 - 23 = -7

Square each deviation score:

17^2 = 289

2^2 = 4

(-8)^2 = 64

(-4)^2 = 16

(-7)^2 = 49

Calculate the sum of the squared deviation scores:

Sum of squares = 289 + 4 + 64 + 16 + 49 = 422

Therefore, the correct option is (C) 422

The reasonable domain for this function is 0 < x < 50

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The range of a function is defined as the set of all the possible output values that are valid for the given function.

Given;

A = 50W - W2

The area of a rectangle cannot be negative;

The practical domain of A is determined when;

50W-W^2>0

Taking common factor W

W(50-W)>0

Since W must be positive W>0

50-W>0

Or equivalently

Therefore the volume of the gas is 14cubic feet.

The equation of state of an ideal gas, often known as the general gas equation, is the ideal gas law. Even though it has a number of restrictions, it is a good approximation of the behavior of various gases under a variety of situations. rules relating to gases, which link a gas's volume, pressure, and temperature. In accordance with Boyle's law, which bears Robert Boyle's name, a gas's pressure P and volume V vary inversely at constant temperature. PV = k, where k is a constant, is the formula for this relationship. As the pressure lowers, the gas volume rises according to Boyle's Law. According to Charles' Law, as a gas's temperature rises, its volume expands. We also know from Avogadro's Law that as gas concentration rises, so does its volume.

The volume of a gas varies directly with its temperature and inversely with the pressure.

V ∝ T/P

V= Volume of the gas at constant mass

T= Temperature at constant mass

P= pressure at constant mass

\(V_{1} /V_{2}\) = \(\frac{T_{1}/ T_{2}}{P_{1}/ P_{2}}\)

At constant mass, the volume of a certain gas is 10 cubic feet and a pressure of 30 pound per square inch at a temperature 300 k.

\(V_{2}\) = 14 cubic feet

The probability of selecting a white marble on the second draw, given that the first marble drawn was black, is approximately 0.7234.

Conditional probability is the probability of an event occurring given that another event has already occurred

Let B denote the event of selecting a black marble on the first draw, and W denote the event of selecting a white marble on the second draw. We are given that P(B) = 0.47 and P(B∩W) = 0.34.

To find P(W|B), we can use the formula for conditional probability

P(W|B) = P(B∩W) / P(B)

Substituting the given values, we get

P(W|B) = 0.34 / 0.47

Simplifying this expression, we get

P(W|B) ≈ 0.7234
