At a birthday party, 5 boys and 3 girls are seated in a row. How many different arrangements are possible if there are no boys between any two girls?
Answer:
Basic Concept:
Since there are no boys between 2 girls, we will take the 3 girls as 1 single unit and permute the seats
We have 6 slots (5 for boys and 1 for all 3 girls)
We have 6 slots and 6 people to sit on them (taking the 3 girls as one)
Permutations:
So, the total number of seating arrangements is 6P6
which will be equal to 6 factorial (6P6 = [tex]\frac{n!}{n! - r!}[/tex] = [tex]\frac{6!}{6! - 6!}[/tex] = 6! (since 0! = 1))
Total possible seating arrangements = 6!
Total possible seating arrangements = 720

In the equation 0.44 x 0.72 = n, what is the value of n?
Answer:n=0.3168
Step-by-step explanation:
Answer:
n = .3168
Step-by-step explanation:
Multiply .44 by .72.
You can use a calculator to do this or do it by hand.
If you choose to do it by hand, multiply using long multiplication without paying mind to the decimals, and then when you are finished, add the decimal four places to the left (at the very beginning of the number you should get). So, 3168 becomes .3168, or your final answer.
Sorry, I cannot really show all the steps of the multiplication itself on a computer but I hoped this helps :)

explain the types of angle like angle at a point supplementary angle pls . donot steal my point
Answer:
A supplementary angle is an angle that forms 180°. To put into simpler words, it's the angle that makes a straight line.
A complementary angle is an angle that makes a 90° angle or a right angle.
An acute angle is an angle that is less than 90°.
An obtuse angle is an angle that is between 90 & 180 degrees.
A reflex is one that makes a 270° angle.
And finally you have a full/complete angle which makes a 360° angle

If Diego started the race at 11:38 am and finished in 90 minutes, then the time he will finish the race is 12:58 pm, the correct option is D.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The equations are of various types, such as Trigonometric equations, quadratic equations.
Diego ran a race in 80 minutes, the race started at 11:38 a.m.
The time Diego ran a race in is 80 minutes.
The time he started at 11:38 am
Let he finish the race at x hours.
The equation can be written as,
x = 11:38 + 80 minutes
60 min = 1 hour
80 minutes = 1 hour 20 minutes
x = 11: 38 + 1 :20
x = 12: 58 pm
The time he will finish the race is 12:58 pm.
