Answer:

900 g

Step-by-step explanation:

Here, we want to get the weight of the 5th parcel

Mathematically, the total

is the mean multiplied by the count

the four parcel weighted 400 g averagely

The mean of this is 400(4) = 1,600 g

Adding the 5th parcel, we have an average of 500 g

This means that the total will be;

500(5) = 2,500 g

the difference in weight is the weight of the 5th parcel

That’s 2500-1600 = 900 g

The answer is 15. hope this helps!

Graph 3

How to choose the correct graph?

Before choosing the correct graph, we must classify the function as discrete or continuous, as follows:

Discrete function: the input values of the function are only certain values on an interval.

Continuous function: the input values of the function are all the real values in the interval.

Then the graph of each type of function is given as follows:

Discrete function: dots.

Continuous function: solid line.

The input and output variables in this problem are given as follows:

Input variable: number of chapters.

Output variable: number of pages.

The number of chapters assumes only integer values, hence the function has a discrete domain, meaning that the graph is composed by dots.

However, the first graph is correct, as the third graph has a range of input and output values that is not present on the table, while the range in the first graph is according to the table.

Answer: image 4

Step-by-step explanation: did it on edge and was correct

The final image after composition ry-axis ◦ T3, -1 is Figure 4.

Thus, figure 4 is correct figure.

Given transformation rule, ry-axis ◦ T3, -1.

First, reflect the coordinates of LMNP across y axis by the rule

(x, y) -> (-x, y)

Then, translation 3 units to the right and 1 unit down

So, if the original point was (x, y), after the translation it becomes (x + 3, y -1 ).

Now, the coordinates of LMNP are:

L (-5, 1), M (-5, 4), N(-3, 4) and P(-3, 1).

Then, after reflection from y axis

L' (5, 1), M' (5, 4), N'(3, 4) and P'(3, 1).

and, after Transformation T (3, -1) the coordinates are:

L' (5+3, 1-1)  - L"(8, 0),

M' (5 +3, 4-1) = M"(8, 3),

N'(3+3, 4-1) = N"(6, 3),

P'(3+3, 1-1) = P"(6, 0)

Therefore, the required transformed figure is (4).

We can find the horizontal distance traveled by the stream using the horizontal component of the velocity and the time taken as follows:d = Vcosθ x T = 26 x cos 5° x 1.84 = 42.5 m Thus, the stream of water lands 42.5 m away from the nozzle.

Given,Velocity of the stream of water from the nozzle, V

= 26 m/s Angle of projection, θ

= 35°Let 'd' be the distance from the nozzle where the water stream lands.From the given data, we know that the stream of water ejects 280 liters of water per minute i.e. 280/60 liters of water per second i.e. 4.67 liters of water per second i.e. 4.67 x 10⁻³ m³ of water per second.Therefore, the volume of water passing through the cross-sectional area of the stream per second is 4.67 x 10⁻³ m³/s.Assuming that the cross-sectional area of the stream is circular, its radius can be calculated as follows:r

= [Volume flow rate] / [Area of cross section]

= [4.67 x 10⁻³] / [π x (0.5 x 10⁻³)²]

= 5.96 x 10⁻³ m.Now we know that the horizontal component of the velocity remains constant throughout the path and the vertical component follows uniformly accelerated motion.Using the vertical component, we can calculate the time taken by the stream to hit the ground as follows:Vsinθ

= gTwhere g is the acceleration due to gravity

= 9.8 m/s²Therefore, T

= [Vsinθ] / g

= [26 x sin35°] / 9.8

= 1.84 s . We can find the horizontal distance traveled by the stream using the horizontal component of the velocity and the time taken as follows:d

= Vcosθ x T

= 26 x cos 5° x 1.84

= 42.5 m Thus, the stream of water lands 42.5 m away from the nozzle.

To prevent misunderstandings, it's crucial to pronounce each symbol and operation loudly when reading mathematical statements.

An expression, which is used to indicate a mathematical relationship or calculation, is a set of numbers, symbols, and operators. Variables are placeholders for unknowable values that can subsequently be replaced by known values and are a common component of expressions. For instance, "2x + 3" denotes a calculation that involves multiplying 2 by a variable x, adding 3, and then doing the addition. The calculation represented by the formula "3y - 7" involves multiplying 3 by a variable called y and then taking that number out. In addition, parentheses, exponents, and other mathematical operations can be used in expressions to define more complicated calculations.

Answer:

325 adults and 612 students entered the school play

Step-by-step explanation:

1st equation: x is the number of adults and y the number of students.

2nd equation: Students times what they payed + adults times what they payed:

1st:          x + y = 937

2nd:       2x + 0.75y = 1109

x = 937 - y

Now let's replace x for (937 - y) in the 2nd equation, to find out the value of y:
2(937 - y) + 0.75y = 1109

1874 - 2y + 0.75y = 1109

1874 - 1.25y = 1109

-1.25y = 1109 - 1874

-1.25y = -765 (multiply -1)

1.25y = 765

y = 765 / 1.25

y = 612

Now that we found the y value, let's replace it in the 1st equation to find out the value of x:

x + 612 = 937

x = 937 - 612

x =  325

If you want to double check it, you can replace both in the 2nd equation, to make sure:
2 * 325 + 0.75 * 612 = 1109

650 + 459 = 1109  (checked)

Answer:

3014 cubit foot

Step-by-step explanation:

Find the diagram attached

Volume of the cone = 1/3πr²h

r is the base radius of the cone

h is the height

Given

r = 6ft

Get the height using the pythagoras theorem

h² = 10² - 6²

h² = 100 - 36

h² = 64

h = √64

h = 8ft

Get the volume

Volume = 1/3πr²h

Volume = 1/3 * 3.14 * 6^2*8

Volume = 3.14 * 12 * 8

Volume =3,014.4

Volume = 3014 cubit foot to the nearest foot

The answer is, the area of the parallelogram is 50 square feet.

To find the area of a parallelogram, you can use the following formula: Area = base × height. The base is the length of one side of the parallelogram, and the height is the perpendicular distance between the base and the opposite side. Here's a step-by-step explanation:

1. Identify the length of the base of the parallelogram.
2. Identify the height of the parallelogram, which is the perpendicular distance between the base and the opposite side.
3. Multiply the base and the height to find the area.

For example, if you have a parallelogram with a base of 10 ft and a height of 5 ft, the area would be:

Area = base × height
Area = 10 ft × 5 ft
Area = 50 ft²

So, the area of the parallelogram is 50 square feet.

The relative frequency of deaths in a specific population is referred to as the mortality rate.

The mortality rate is a key measure used to understand the level of fatalities within a population. It represents the number of deaths per unit of population over a specific period typically expressed as deaths per 1,000 or 100,000 individuals.

The mortality rate provides valuable insights into the health and well-being of a population and is widely used in public health, epidemiology, and demographic studies. By monitoring changes in the mortality rate over time, researchers and policymakers can identify trends, assess the impact of interventions, and develop strategies to improve population health outcomes.
