Step-by-step explanation:
There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.
There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.
It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.

Can someone help me with this umm math thingy
Answer:
1. The similar triangles are ΔXYZ and ΔPQR
The triangles are similar by the AA rule of similarity
2. The similar triangles ΔXYZ and ΔPQR cannot be assumed as being congruent because more information are required about the length of a pair of corresponding sides of both triangles
3. x = 17.5
4. x = 20
Step-by-step explanation:
1. The angles of triangle ΔXYZ are;
∠X = 32°, ∠Y = 84° and ∠Z = 180° - (84° + 32°) = 64°
The angles of triangle ΔPQR are;
∠P = 64°, ∠R = 32° and ∠Q = 180° - (64° + 32°) = 84°
The angles of triangle ΔABC are;
∠A = 64°, ∠C = 92° and ∠B = 180 - (92 + 64) = 24°
Therefore, the two similar triangles are ΔXYZ and ΔPQR
The triangles are similar based on Angle-Angle (AA) rule of similarity
2. The similar triangles ΔXYZ and ΔPQR cannot be assumed as being congruent because more information are required about the length of a pair of corresponding sides of both triangles
3. We have by corresponding triangles formed by the tree and Enzo as follows;
5 ft./(6 ft.)= x/(21 ft.)
∴ x = 21 ft.× (5 ft./6 ft.) = 17.5 ft.
x = 17.5 feet
4. By corresponding triangles, we have;
(35 ft.)/(40.5 ft.+ 54 ft.) = x ft./(54 ft.)
∴ x ft. = (54 ft.) × (35 ft.)/(40.5 ft.+ 54 ft.) = 54 ft. × (35 ft.)/(94.5 ft.) = 20 ft.
x ft. = 20 ft.
∴ x = 20

Answer:
For right angle triangle,
we use Pythagoras theorem that is:
[tex]c^{2} =a^{2} +b^{2}[/tex]
c = [tex]\sqrt{a^{2} +b^{2} }[/tex]
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c = [tex]\sqrt{40^{2} + 9^{2} }[/tex]
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c = [tex]\sqrt{12^{2} + 13^{2} }[/tex]
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]35^{2} = 20^{2} + b^{2}[/tex]
1225 = 400 + [tex]b^{2}[/tex]
[tex]b^{2}[/tex] = 1225 - 400
[tex]b^{2}[/tex] = 825
[tex]\sqrt{b^{2} } = \sqrt{825}[/tex]
b = 5 [tex]\sqrt{33}[/tex]
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
[tex]c^{2} =a^{2} +b^{2}[/tex]
[tex]37^{2} = 20^{2} + b^{2}[/tex]
1369 = 400 + [tex]b^{2}[/tex]
[tex]b^{2}[/tex] = 1369 - 400
[tex]b^{2}[/tex] = 969
Taking square root on both sides
b = 31.12
Hope it helps.

Solve the quadratic inequality
4x^2-25<0
I hope it helps you ❤️❤️❤️❤️
The solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.
Solution to the inequality
The solution to the inequality is obtained by solving the inequality as shown below;
4x^2 - 25 < 0
add 25 to both sides of the equation;
4x² < 25
divide both sides by 4
x² < 25/4
take square root of both sides
x < 5/2
Thus, the solution to the inequality, 4x^2 - 25 < 0 is determined as x < 5/2.

Leila needs to buy plastic spoons. Brand A has a box of 25 spoons for $1.97. Brand B has a box of 48 spoons for $2.98. Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.
Answer:
The unit price is the price of a single unit.
To find it, you need to find the quotient between the total price and the number of objects you get for that price.
Brand A:
You get 25 spoons for $1.97
Then the unit price is:
unit price of brand A = $1.97/25 = $0.079
Brand B:
You get 48 spoons for $2.98
Then the unit price is:
unit price of brand B: $2.98/48 = $0.062
Here we can see that the unit price for brand B is smaller, then the better buy is brand B.

The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.
Write a combined variation equation and find y when x = 6 and z= 3.
Given:
The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.
To find:
The combined variation equation and find y when x = 6 and z= 3.
Solution:
The variable y varies directly as x and inversely as z.
[tex]y\propto \dfrac{x}{z}[/tex]
[tex]y=k\dfrac{x}{z}[/tex] ...(i)
Where, k is the constant of proportionality.
Putting x=4, y=2 and z=14, we get
[tex]2=k\dfrac{4}{14}[/tex]
[tex]2=k\dfrac{2}{7}[/tex]
[tex]2\times \dfrac{7}{2}=k\dfrac{2}{7}\times \dfrac{7}{2}[/tex]
[tex]7=k[/tex]
Putting k=7 in (i), we get
[tex]y=7\dfrac{x}{z}[/tex]
Putting x=6 and z=3, we get
[tex]y=7\times \dfrac{6}{3}[/tex]
[tex]y=7\times 2[/tex]
[tex]y=14[/tex]
Therefore, the required equation is [tex]y=7\dfrac{x}{z}[/tex] and the value of y is 14 when x = 6 and z= 3.

Melissa earns a 2% commission on the first $750 of sales she makes each week. She earns a 3% commission on the amount of her sales that are greater than $750 each week. Melissa earned $37.50 in commissions last week.
Which equations correctly calculate how much money in dollars, x, Melissa made in sales last week?
Select all that apply.
0.02(750)+0.03(750−x)=37.5
0.03(x−750)=37.5−15
15+0.03x−22.5=37.5
0.02(750)+0.03(x−750)=37.5
15−0.03x+22.5=37.5
0.03(750−x)=37.5−15
The equations that are correct are:
0.02(750) + 0.03(x - 750) = 37.5
0.03(750 - x) = 37.5 - 15
Given:
Melissa earns a 2% commission on the first $750 of sales.
She earns a 3% commission on greater than $750 each week.
1. Sales up to $750:
Melissa earns a 2% commission on the first $750 of sales.
=0.02(750)
= 15
2. Sales exceeding $750:
Melissa earns a 3% commission on the amount of sales that exceed $750.
0.03(x - 750) = 37.5 - 15
Combining both equations, we have:
0.02(750) + 0.03(x - 750) = 15 + 37.5 - 15
15 + 0.03x - 22.5 = 37.5
0.03x - 7.5 = 37.5
Adding 7.5 to both sides
0.03x = 45
Dividing both sides by 0.03
x = 1500
Therefore, the correct equations that calculate the amount of money Melissa made in sales last week are:
Equation 1: 0.02(750) + 0.03(x - 750) = 37.5
Equation 2: 0.03(750 - x) = 37.5 - 15

Find the probability of rolling a 5 or 6 on a fair dice
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
[tex]\frac{1}{6}[/tex] + [tex]\frac{1}{6}[/tex]
This is because there is only one "5" and one "6" in a dice. Moreover the total number of numbers in a dice are 6 so the denominator will be 6. Then when the word 'or' is present it means that both the probabilities must be added.
P (of rolling a 5 or 6 on a fair dice) = [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{6}[/tex]
[tex]\frac{2}{6}[/tex] can be simplified further. Both 2 and 6 are factors of 2 so..
[tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]
P (of rolling a 5 or 6 on a fair dice) = [tex]\frac{1}{3}[/tex]
