Answer:

Nephews= 7.75

Nieces=8.1

Down below is how you slove this :)) Hope it helps

Step-by-step explanation:

How you find the answer is first you add the total amount of nephews together than the nieces. you then count how many there are so like for nephews there are 4,10,8,9 so when you count them that is 4 so when you add 4,10,8,9 together you divide that by 4 since there are for then you do the same with nieces 5.4,10,8,9 and you get 32.4 then you divide that by 4 because there are 4 and you get 8.1 so the average age of nieces is 8.1 and nephews is 7.75

Answer:

the number is 12

Step-by-step explanation:

9+2x=3x-3

9+3=3x-2x

12=x

The required number is 12.

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that,9 more than twice a number is 3 less than three times the same number.

Let the number be x.

So, 9 more than twice a number = 9 +2x

and, 3 less than three times the same number = 3x - 3

Hence we have,

9 + 2x = 3x - 3

Adding 3 both the side we get,

12 + 2x = 3x

Now substracting 2x both the side we get,

x = 12

Hence the number is 12.

Answer:

1st one is 6.9 X 10^6

2nd one is 2 x 10^5

Step-by-step explanation:

The equation which represents the relationship between X values and Y values can be found by deriving the equation of line using slope intercept form. The equation of line is 3x - 5y = 25.

How to find equation of line using slope intercept form?

Equation of line using slope intercept form is y = mx + b

where m is slope of the line and b is y-intercept

The slope intercept can be used to form equation of line using two points on the line.

According to the given question:

The two points which lie on the line are (x, y) = (5, -2) and (x', y') = (0, -5)

Slope of the line m = y' - y/x' - x

                               = (-5 +2)/(0 - 5)

                               = 3/5

Now y intercept b = y - mx

                              = -2 - (3/5. 5)

                              = -5

Therefore the required equation of line is y = 3/5x - 5

On simplifying further 3x - 5y = 25

Answer:

6,785.84 m³ (cubic meters)

Step-by-step explanation:

The rate of flow given in m/s = 0.8 m/s
Since the pipe has a radius of 1.5 m
Volume of water that flows in 1 second = π x 1.5² x 0.8 m

=  π x 12.25 x 0.8 m³ / second

= 1.8π m³/s

20 minutes = 20 min x 60 seconds/min = 1200 seconds

In 1200 seconds, the amount of water that flows out of the pipe
= 1200 s x 1.8π m³/s

= 2,160π m³

= 6,785.84 m³

The cost of the molding is given as follows:

$119.30.

The circumference of a circle of radius r is given by the equation presented as follows:

C = 2πr.

The parameters for this problem are given as follows:

d = 9 -> r = 4.5.

(as the radius is half the diameter)

Hence the circumference is given as follows:

C = 2 x π x 4.5

C = 28.27 ft.

The cost is of $4.22 per ft, hence the total cost is given as follows:

4.22 x 28.27 = $119.30.

Answer:

25 mph

120 miles

Step-by-step explanation:

We have that the speed is equal to:

v = d / t

if we solve for distance:

d = v * t

in this case, since it is the same route both outward and back, the distances are equal, therefore:

v1 * t1 = v2 * t2

t1 = 4 hours

t2 = 6 hours

v1 = x + 5 (downstream speed)

v2 = x -5 (upstream speed)

replacing:

(x + 5) * 4 = (x - 5) * 6

4 * x + 20 = 6 * x - 30

6 * x - 4 * x = 20 + 30

2 * x = 50

x = 25

speed is 25 mph

now the distance would be:

d = (25 + 5) * 4 = 120

d = (25 - 5) * 6 = 120

In other words, the route was 120 miles.

The best statement that describes the strategy for estimating the perimeter of the figure (please see the attached diagram) is the option;

Ad the lengths of the horizontal and vertical segments, and then add 5 because the diagonal side is 4 units wide and 2 units tall

An estimate is an approximation of a true value, which is a value that is close to the actual value of the measured quantity.

Please find attached a diagram of the possible figure created with MS Word

The length of the side of the sides of the possible figure in the figure, obtained from a similar question on the internet are;

Base length = 5 units

Height = 4 units

The figure has a diagonal side which is 4 units wide and 2 units tall.

The length of the slant side, found using Pythagorean theorem can be obtained as follows; Length = √(4² + 2²) = 2·√5 ≈ 5

The correct option is therefore to add the lengths of the horizontal and vertical segments, and then add 5 because the diagonal side is 4 units wide and 2 units tall

An equation that could be used to determine M, the unknown side length of the logo is X = (36/5) x M

Let's assume that the unknown side length of the logo is 'M'. The logo is a rectangle, and the area of a rectangle is given by multiplying its length and width. Since we know the length of the logo is 7(1)/(5) feet, we can write the equation:

A = L x W

where A is the area of the logo, L is the length of the logo, and W is the width of the logo.

Substituting the given values, we get:

A = (7(1)/(5)) x M

or

A = (36/5) x M

Now, we know that the area of the logo is exactly the maximum area allowed by the building owner. Let's assume this maximum area is 'X'. So, we can write another equation:

A = X

Combining both equations, we get:

X = (36/5) x M

This is the required equation that could be used to determine the unknown side length 'M' of the logo if we know the maximum area allowed by the building owner 'X'.

To calculate the mean is the same as the average value in a data set. Median is data value separating the upper half of a data set from the lower half. The median is the data value separating the upper half of a data set from the lower half. The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number from the largest number.

The equation in terms of x that represents the given relationship is 114 = (1 + 3x) * (Width)

Let's break down the information given:

Height of the rectangular box = 7 ft

Length of the rectangular box = 1 ft longer than thrice the width (x)

Volume of the rectangular box = 798 ft³

To write an equation that represents the given relationship, we need to relate the length, width, and height to the volume.

The volume of a rectangular box is given by the formula: Volume = Length * Width * Height.

Given that the height is 7 ft, we can substitute this value into the equation.

Volume = (Length) * (Width) * (7)

Now, let's focus on the length. It is described as 1 ft longer than thrice the width.

Length = 1 + (3x)

Substituting this value into the equation, we have:

Volume = (1 + (3x)) * (Width) * (7)

Since the volume is given as 798 ft³, we can set up the equation as follows:

798 = (1 + (3x)) * (Width) * 7

Simplifying further, we get:

798 = 7 * (1 + 3x) * (Width)

Dividing both sides of the equation by 7, we have:

114 = (1 + 3x) * (Width)

Therefore, the equation in terms of x that represents the given relationship is:

114 = (1 + 3x) * (Width)

The mathematical operations are addition, subtraction, multiplication, and division.

These mathematical operations are used to determine the output value, given some input values.

The number of foreign students from country B = 138,000

Students from country B are 22% more than the number of students from country C.

Assume that the number of students from country C = 100%

Then the number of students from country B = 122% (100 + 22)

If the number of foreign students from country B is 138,000, which is 22% more, then the number of students from country C is as follows:

Answer:

38.28cm²

Step-by-step explanation:

The area of the figure can be determined by expression the figure as two shapes.

  A semicircle and trapezium;

 Area of shape  = Area of semicircle + Area of trapezium

Now;

 Area of semicircle  = \(\frac{\pi r^{2} }{2}\)

  Where r is the radius, which is \(\frac{4}{2}\) = 2cm;

   Area of semicircle  = \(\frac{3.142 x 2^{2} }{2}\)   = 6.28cm²

Area of trapezium;

        = \(\frac{1}{2} (a + b)h\)

a and b are the base length = 6cm and 10cm

 h is the height = 4cm

Input the parameters and solve;

       =  \(\frac{1}{2} (6 + 10) 4\)  

       = 32cm²

The area of the shape = 6.28cm² + 32cm² = 38.28cm²
