Answer:

-6 1/4

Step-by-step explanation:

3 1/2 - 9 3/4

Get a common denominator

3 1/2 * 2/2 - 9 3/4

3 2/4 - 9 3/4

Subtract the smaller number from the larger number and take the sign of the larger

9 3/4 - 3 2/4

6 1/4

The sign is negative for 9 3/4 so

- 6 1/4

The probability of rolling a number less than 5 is 0.667.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event asked. The value is expressed from zero to one. An outcome is a value we can obtain.

As we are given a 6-sided dice therefore,

Total possible outcomes = 6

Favorable outcomes (that is less than 5) = 4                 [that are; 1, 2, 3, 4]

probability = number of favorable outcomes/number of possible outcomes

probability = 4/6

4/6 = 2/3

= 0.6666666666666

To round the value to three decimal places, we need to see if the fourth value after decimal is more than 5 or not. If it is more than 5, preceding digit is increased by 1. therefore, by applying the rule to the value we get

= 0.667                         [rounded to three decimal places as needed]

therefore, the probability of the event given, that is rolling a number less than 5 is 0.667.

Answer:

\(6 \sqrt{8} \sqrt{2} = 6 \sqrt{16} = 6(4) = 24\)

B is the correct answer.

You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.

When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.

A cuboid has six faces, but each face has a pair that is identical in size and shape.

Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.

To find the surface area of a cuboid, you can add up the areas of all its faces.

However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:

(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.

By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.

Essentially, you are considering one face from each pair and then summing their areas.

Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.

When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.

Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.

Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.

====================================================

Explanation:

The three angles add to 180, so x+y+z = 180

The second and third angles add to 3 times the measure of the first, so y+z = 3x

The third angle is 29 more than the second, so z = y+29

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

The system of equations is

\(\begin{cases}x+y+z = 180\\\\y+z = 3x\\\\z = y+29\end{cases}\)

For now, let's focus on the second and third equations only.

Start with y+z = 3x. Replace z with y+29 which is valid because of the third equation.

So we'll have

y+z = 3x

y+y+29 = 3x

2y+29 = 3x

Let's isolate y

2y+29 = 3x

2y = 3x-29

y = (3x-29)/2

y = 3x/2 - 29/2

y = 1.5x - 14.5

We'll use this later.

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

Go back first equation of the system. Plug in z = y+29

x+y+z = 180

x+y+y+29 = 180

x+2y+29 = 180

Then plug in y = 1.5x - 14.5 we found earlier

x+2y+29 = 180

x+2(1.5x-14.5)+29 = 180

x+3x-29+29 = 180

4x = 180

x = 180/4

x = 45

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

We can use this x value to find y

y = 1.5x - 14.5

y = 1.5*45 - 14.5

y = 53

and use this to find z

z = y+29

z = 53+29

z = 82

As a check, x+y+z = 45+53+82 = 180 to help confirm the answer. I'll let you check the other equations.

The question is incomplete. Here is the complete question,

The equation for the change of position of a train starting at x = 0 m is given by x =(1/2)at² + bt³. The dimensions of b are__

from the equation of motion given, the constant b is the velocity of the body. For us to get the dimension of b, we have to find the dimension of the velocity .

Since velocity is the rate of change of displacement of a body, then;

VELOCITY = DISPLACEMENT/TIME

displacement is measured in metres while time in seconds.

expressing the formula in terms of its fundamental unit,

v = metre/secs

Since the fundamental quantity of the metre is length (L) and that of seconds is the time (T); the dimensions is expressed as;

V = L/T

V = L * 1/T

V = L * T⁻¹

V = LT⁻¹

Hence the dimension of b is  LT⁻¹.

Note that the dimension of a body is written in terms of its fundamental quantities.

The dimensions of b from the given equation are; B: LT⁻¹

The complete question is;

The equation for the change of position of a train starting at x = 0 m is given by x =(1/2)at² + bt³. The dimensions of b are__

Now, in that equation above, b represents the velocity of the motion. Now, the formula for velocity is;

to find the value of m or the value of slope we have to solve for y

Let's solve,

\(2y - 3x = 8 \\ 2y = 8 + 3x \\ \frac{2y}{2} = \frac{8 + 3x}{2} \\ y = 4 + \frac{3x}{2} \\ y = \frac{3x}{2} + 4\)

growth rate: 4

y-value: 19

equation: y=4x+19

Step-by-step explanation:

Growth Rate:
The growth rate of a linear function is constant. This means that the function will increase or decrease by the same amount for every unit increase in x.
This can be found by dividing the change in y-values by the change in x-values.

For the question:
The change in y-values is 11-7=4,

and the change in x-values is +1.

Therefore, the growth rate is 4.

\(\hrulefill\)

Initial Value: The initial value of a linear function is the value of the function when x is 0.

In this case, the initial value is 19.

This can be found by looking at the y-value of the point where x is 0.

In this case, the y-value is 19.

\(\hrulefill\)Equation: The equation of a linear function is y = mx + b, where m is the slope and b is the y-intercept.

Using the table you provided, we can find the slope by using two points on the line.

Let’s use (-3, 7) and (1, 23).

The slope is (y2-y1)/(x2-x1)=(23-7)(1-(-3)=16/4=4

Now,

Taking 1 point (-3,7) and slope 4.

we can find the equation by using formula:

y-y1=m(x-x1)

y-7=4(x+3)

y=4x+12+7

y=4x+19

Therefore, the equation of the given table is y=4x+19\(\hrulefill\)

Answer:

Growth rate:  4

Initial value:  19

Equation:  y = 4x + 19

Step-by-step explanation:

The slope of a linear function represents its growth rate.

Therefore, the growth rate of a linear function can be found using the slope formula.

Substitute two (x, y) points from the table into the slope formula, and solve for m.  Substituting points (0, 19) and (1, 23):

\(\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{23-19}{1-0}=\dfrac{4}{1}=4\)

Therefore, the growth rate of the linear function is 4.

The initial value of a linear function refers to the y-intercept, which is the value of the y when x = 0.

From inspection of the given table, y = 19 when x = 0.

Therefore, the initial value of the linear function is 19.

To write a linear equation given the growth rate (slope) and initial value (y-intercept), we can use the slope-intercept formula, which is y = mx + b. The slope is represented by the variable m, and the y-intercept is represented by the variable b.

As the growth rate of the given linear function is 4, and the initial value is 19, substitute m = 4 and b = 19 into the slope-intercept formula to create the equation of the linear function represented by the given table:

\(\boxed{y=4x+19}\)

The ratio of the volume of water in Jug B to the volume of water in Jug C is 35:18.

Let's assume the volume of water in Jug B is x.

According to the given information, Jug A contains 6/7 as much water as Jug B. Therefore, the volume of water in Jug A can be calculated as (6/7) * x.

Similarly, Jug C contains 3/5 as much water as Jug A. Hence, the volume of water in Jug C can be expressed as (3/5) * [(6/7) * x].

To find the ratio of the volume of water in Jug B to the volume of water in Jug C, we divide the volume of water in Jug B by the volume of water in Jug C:

The volume of the triangular prism is 135 cm³.

To calculate the volume of a triangular prism, we multiply the area of the triangular base by the height of the prism.

Given the dimensions provided:

Base: Length = 5 cm, Width = 9 cm

Height: 6 cm

To find the area of the triangular base, we use the formula for the area of a triangle:

Area = (1/2) * base * height

Substituting the values:

Area = (1/2) * 5 cm * 9 cm

Area = 22.5 cm²

Now, to calculate the volume of the prism, we multiply the area of the base by the height:

Volume = Area * Height

Volume = 22.5 cm² * 6 cm

Volume = 135 cm³

It is very easy to find the perimeter of a square when its area is given in the question. For that, you only ned to know one fomula. That formula is: Area = side^2

For this particular question, the given value for the area of the square is 36 sq.cm. So, we can solve for the side(s) by substituting the given value in the above mentioned formula.

We get

36 = s^2

Now, we need to get the square root of both sides, which gives us

s = √36 s = 6 cm

Since all the sides of a square are equal in length, the side length is 6 cm. Now to determine the perimeter, we must multiply the side length by 4 (because there are 4 equal sides in a square). That gives us Perimeter = 4 x side length Perimeter = 4 x 6 cm.
