The probability of getting the number 10 is 0.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, a die has six faces numbered 1 to 6.
A) Getting the number 6
Probability of getting the number 6 = 1/6
B) Getting the number 10
Probability of getting the number 10 = 0/6
C) Not getting the number 6
Probability of not getting the number 6 = 1-1/6
(6-1)/6 =5/6
D) Getting one of the numbers 1,2,3,4,5 or 6

1. In Luguru Academy, each lesson in lower primary and upper primary classes lasts 30 minutes and 40 minutes respectively. The first time the two bells ring at the same time, the pupils go out for a tea break if lessons of the whole school start at 8:30am. a) At what time does tea break start? b) How many upper primary lessons take place before break? 2. A bottle contained 6 litres of milk. Malimoto took of the remainder. How much milk remained in the bottle? 3. An irregular pentagon has the following four interior angles 110°, 108° 135°, and 152°. Determine the value of the exterior angle adjacent to the fifth interior angle. 4. A candidate scores 45, x and y percent in an interview, what is his average score?
Using LCM, the pupils go out for a tea break at 10.30 a.m, Using property of pentagon, The value of the exterior angle adjacent to the fifth interior angle is 145°.
How do I figure out LCM?Step 1: Use the repeated division method to identify the prime factors of the supplied numbers.
Write the numbers in exponent form in step two. Only those prime factors' product with the highest power should be sought.
Step 3: The LCM of the provided numbers is the product of these factors with the highest powers.
a) Find the moment when two bells will ring simultaneously.
In 30 minutes, the first bell rings.
The second bell will ring in 40 minutes, and classes will begin at 8:30. LCM of 30, 40, equals 120 minutes.
Bath bells sound at the same time at 8.30 a.m. plus 2 hours after 120 minutes, which is 10.30 a.m.
b) 40 + 40 + 40 = 120 minutes
∴ 3 classes will take place before break in upper primary.
An irregular pentagon has the following four interior angles 110°, 108° 135°, and 152°. Determine the value of the exterior angle adjacent to the fifth interior angle.
Sum of angles of pentagon = 540°
⇒ 110° + 108° + 135° + 152 + x = 540
⇒ x = 35
The value of the exterior angle adjacent to the fifth interior angle is 180 - 35 = 145°

The sum of their ages after 3 years will be 46 years.
What is age?
A time frame in a person's life, defined in years from birth, that is frequently characterised by a certain stage or level of mental or physical development and involves the development of legal ability and responsibility is known an age.
Step by step Explaination:
The sum of the ages of the son and father before 5 years was 30 years.
The sum of their ages after 3 years=?
Let us assume that the present age of the son is x years and the father is y years.
So, according to the question
The sum of their ages before 5 years = 30
(x-5)+(y-5) = 30
x+y-10 = 30
x + y = 40
Now, the sum of their age after 3 years will be
(x+3)+(y+3) = x+y+6
substituting the value of x + y
x+y+9 = 40+6= 46 years.
Hence, the sum of their ages after 3 years will be 46 years.

you invest a total of $5000 between two saving accounts. account A pays 2% annual interest and account B pays 4% annual interest. after one year, you have earned a total of $135 in interest. How much did you invest in each account
The Investment in Account A is 1750, Investment in Account B is 3250
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
Given;
The total investment = 5000
Let the amount invested in account A be x
Therefore, the amount invested in account B = 5000-x
In Account A, rate of interest = 4% per year
Thus, interest earn in one year
= x*4*1/100
= 4x/100
Now, The interest in account B = 2% per year
Thus, the interest earn in one year
= (5000-x)*2*1/100
= 2(5000-x)/100
Therefore, total interest;
(x*4*1/100)*((5000-x)*2*1/100)
(2x+10000)/100=35
x=1750

What is a 180 degree angle called?
Angles that are 180 degrees (θ = 180°) are known as straight angles.
A straight angle is a 180-degree angle in mathematics. Straight refers to the fact that it appears as a straight line. Angles are formed when two rays are linked end to end, according to the definition of angles in mathematics.
As a result, the two rays of the 180-degree angle are subtended in the opposite direction, where the rays are united at the ends.
In radians, the 180-degree angle is measured in pi (π). To point the opposite way, the straight angle changes the direction. A 180-degree is also considered supplementary.

If the product of two successive positive integers is 4556, find the sum of these two numbers.
The sum of two successive positive integers is : 135
Let m and (m + 1) be two successive positive integers.
Given that the product of two successive positive integers is 4556
So, we get an equation,
m × (m + 1) = 4556
We need to find these two successive positive integers.
We solve above equation to find the value of m.
m² + m = 4556
m² + m - 4556 = 0
After factorizing above quadratic equation we get,
(m - 67)(m + 68) = 0
m - 67 = 0 OR m + 68 = 0
m = 67 OR m = -68
Sine the required numbers are positive integers we consider m = 67
For m = 67, the two successive positive integers: 67, 68

A hexagonal aquarium is 15. 5 on each side of its base and 28. 5cm high. Whats the area
The area of the hexagons having side 15.5 cm and height 28.5 cm will be 662.625 cm^2.
A hexagon or sexagon is a six-sided polygon or 6-gon that forms the shape of a cube in geometry. The sum of any basic hexagon's interior angles is 720°.
The hexagon has six sides in mathematics; what makes this specific form so fascinating is because it best fills a plane with equal size units and leaves no wasted space. Because of its 120-degree angles, hexagonal packing also reduces the perimeter for a given area.
As we have,
Area of Hexagon = 3/2 x s x h
Where, s = side of hexagons
h = height of hexagons.
So, for determining the value of area of hexagons, we will put the value of (s) and (a) in the above formula.
So, we will get the area of hexagons as:

The probability that the maid of honor is in the leftmost position is 0.00034.
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Let us check a simple application of probability to understand it better. Suppose we have to predict about the happening of rain or not. The answer to this question is either "Yes" or "No". There is a likelihood to rain or not rain. Here we can apply probability. Probability is used to predict the outcomes for the tossing of coins, rolling of dice, or drawing a card from a pack of playing cards.
The probability is classified into theoretical probability and experimental probability.
We have to find the probability that the maid of honor is in the leftmost position.
There is no case, where it generally manages its next groom is = 7 and it will be arranged in the 2, that can be arranged in 2! ways. So, the total number of ways are: 7*2 = 14
∴ The required probability = 14/8! = 1/2880 = 0.00034

what is an angle whose vertex is on the circle and sides are chords?
The angle whose vertex is on the circle and the sides of the angle are the chords is called an Inscribed Angle .
What is an Inscribed Angle ?
An inscribed angle in the circle is formed by the two chords which have a common end point on circle and this common end point is called the vertex of inscribed angle.
The arc formed by the inscribed angle in the circle is called as the intercepted arc .
also the Inscribed Angle Theorem states that inscribed angle on the circle is half the measure of central angle that subtends the same arc .
