there are 1800 pupils in a school of witch 2/5 are girls. 540 of the pupils do not play sports. Of these pupils who do not play sports, 5/9 are girls. How many boys play sports?
========================================================
Explanation:
There are 1800 students total.
Take 2/5 of this to find the number of girls
(2/5)*1800 = 720 students are girls
Subtract that result from the total to get the number of boys
1800-720 = 1080 students are boys
We'll use this value later, so let A = 1080.
-------------
540 students do not play sports
(5/9)*540 = 300 girls do not play sports.
540-300 = 240 boys do not play sports
Let B = 240
------------
We found that
A = 1080 boys totalB = 240 boys do not play sportsTherefore,
A-B = 1080 - 240 = 840 boys play sports

By the angle sum property of a triangle, the value of x would be equal to 9.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
The sum of the triangle of angles is 180.
6x + 56 + 38 + t = 180
t = 180 - 94 - 6x
t = 86 - 6x
By linear pair
10x + 58 + t = 180
10x + 58 + 86 - 6x = 180
4x + 144 = 180
4x = 180 - 144
4x = 36
x = 9

if [tex]v=v_{1} +v_{2}[/tex], where [tex]v_{1}[/tex] and [tex]v_{2}[/tex] are not both 0 and [tex]u=-3v[/tex], find the measure of the angle between [tex]u[/tex] and [tex]v[/tex].
Given:
[tex]\frac{u*v}{||u|| ||v||}[/tex]
If θ is the angle between u and v, then
u • v = ||u|| ||v|| cos(θ)
Since u = -3v, we have
u • v = (-3v) • v = -3 ||v||²
and
||u|| = ||-3v|| = 3 ||v||
If v₁ and v₂ are both not zero, then ||v| ≠ 0.
Then
cos(θ) = (-3 ||v||²) / (3 ||v|| ||v||) = 1
which means θ = π rad = 180°.

The Mean, Median and Mode of the given set of data ( 11, 12, 32, 43, 45, 48, 48, 48 ) are 35.875, 44 and 48 respectively.
What is Arithmetic mean?Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Given the sets;
48, 12, 11, 45, 48, 48, 43, 32n = 8First, we arrange in ascending order.
11, 12, 32, 43, 45, 48, 48, 48
Mode
Mode is the number with the highest appearance
Number with highest appearance or frequency is 48 ( 3 appearance )
Mode = 48
Median
Middle numbers fall between 43 and 45
Median = ( 43 + 48 ) / 2
Median = 88 / 2
Median = 44
Mean
We add the numbers
11 + 12 + 32 + 43 + 45 + 48 + 48 + 48 = 287
Mean = Sum total of the number ÷ n
Mean = 287 / 8

C. City C.
What is the mode of a data-set?It is the value that appears the most times in the data-set. If two values appear the same number of sets, the data-set is called bimodal.
Hence, looking at the table:
For City A, 10 appears three times, hence it is the only mode.For City B, 25 appears five times, hence it is the only mode.For City C, 42 and 66 each appear three times, hence they are the modes, and the data-set is bimodal.For City D, 78 appears three times, hence it is the only mode.Hence option C is correct.

Juan borrowed $10 from his cousin. He borrowed another $30 from his uncle. Juan bought a $10 lottery ticket and won $100. How much money will Juan have after he pays his cousin and uncle back?
Answer:
$90
Step-by-step explanation:
Since Juan pays back the $10 and $30 he borrowed from his cousin and uncle they do not affect the total outcome ($10+$30-$10-$30=0)
Subtract the price of the ticket from the total amount he won.
$100-$10=$90
Suppose that 2 ≤ f '(x) ≤ 4 for all values of x. What are the minimum and maximum possible values of
f(5) − f(1)?
Answer:
Step-by-step explanation:
By the Mean Value Theorem, there is at least one number, c, in the interval (1,6) such that
f'(c) = [f(6) - f(1)]/ (6 - 1)
So, f(6) - f(1) = 5f'(c).
Since 2 ≤ f'(c) ≤ 4, 10 ≤ 5f'(c) ≤ 20
So, f(6) - f(1) is between 10 and 20.
Which statements describe the figure on the grid if each square has side lengths of 1 cm? Check all that apply. On a coordinate plane, a figure covers 12 full squares and 12 partial squares. The bottom of the figure is diagonal and crosses 6 squares. The perimeter of the figure is 18 cm. The length of the top of the figure is less than 6 cm. The area of the figure is the sum of 12 full squares and 12 partial squares. The area of the figure is greater than 24 square centimeters. The length of the bottom of the figure is greater than 6 cm. The area of the figure is the sum of 6 full squares and 12 partial squares.
The figure on the grid is an illustration of areas and perimeters of a shape
How to determine the true statements?The question is incomplete, as the figure is not given.
So, I will provide a general explanation on how to determine the area and the perimeter of a shape.
The area of a shape is the amount of space on that shape.
Take for instance a square that has a side length 5 units.
The area of the square would be:
Area = 5 * 5 = 25 square units
On the other hand, the perimeter is the sum of the side lengths of the shape.
Using the same square that has a side length 5 units.
The perimeter of the square would be:
Perimeter = 4 * 5 = 20 units

Suppose y varies directly with x. If y is 8 when x is 12, find y when x is 18.
[tex]\large\textsf{\textbf{Answer\::}}[/tex]
Please consult the "calculations" section of this ans .
[tex]\large\textsf{\textbf{Calculations\::}}[/tex]
If y varies directly with x , the equation looks like this :
y=kx , where k is the constant of proportionality
Plug in the values :
8=k/12
Multiply times 12 on both sides :
96=k
So the constant of proportionality is 96 .
Now solve for y when x is 18 as follows :
y=96/18
y≈5.33
