There are 39 adults and 26 children registered for a seminar. the seating is to be arranged so each row has the same number of people. all of the people in a row must be in the same age group. how many rows of seats are needed to seat the greatest possible number of participants in each row?
Answers
The number of rows of seats needed to seat the greatest possible number of participants in each row is 5
What is Highest Common Factor ?The highest common factor is the highest number that divides the numbers given.
On the basis of given data
Total number of children = 26
Total number of adults = 39
The highest common factor of both the number is 13 ,
Therefore the highest possible number of people that can sit in one row so that the number is in constant in all the rows.
So 2 rows of children of 13 each and
3 rows of adult of 13 each
Which makes the total number of rows = 5
Therefore the number of rows of seats needed to seat the greatest possible number of participants in each row is 5

25. the result was 34 what was my number?
Answers
Answer:63
Step-by-step explanation:
63/7+25=34
Answer:
x = 63
Step-by-step explanation:
we know that...
(x will be the stand-in for "your number")
x ÷ 7 + 25 = 34
(x ÷ 7) + 25 = 34
To find x, we have to isolate x
first, we can subtract 25 from both sides (remember, if you do an action on one side, you must do the same action on the other side)
{why are we subtracting? we need to do the opposite of a sign to get rid of it. By subtracting, we are undoing addition; by multiplying we are undoing division (and vice versa) }
(x ÷ 7) + 25 = 34
- 25 - 25 (subtract 25)
x ÷ 7 = 9
× 7 ×7 (multiplying by 7 to get rid of the "÷7")
x = 63
now, we can test out our x-value:
(63 ÷ 7) +25 = 34
( 9 ) + 25 = 34
34 = 34
because this equation is true, we can be certain that x = 63

A swimming pool of 25m long and 20m wide is filled with water to a depth of 5m. what is the volume of water when it is 3/4 full?
Answers
Answer:
[tex]1875m^{3}[/tex]
Step-by-step explanation:
To find [tex]\frac{3}{4}[/tex] of the volume, we first must know the total volume.
The formula to find volume:
[tex]volume = length * width * depth[/tex]
We know the length is 25m, we know the width is 20m and we know the depth is 5m.
So, we can substitute them into the equation:
[tex]volume=25*20*5=2500m^{3}[/tex]
Now we know the total volume, we can find out the volume when it is [tex]\frac{3}{4}[/tex] full:
[tex]\frac{3}{4} * 2500 = 1875m^3[/tex]
Therefore, our final answer is [tex]1875m^{3}[/tex].
A survey was given to ask a group of adults if they liked chocolate or vanilla ice cream more. The table shows the survey results of three age groups.

A person is selected at random. Determine the probability of each described event. Round your answers to two decimal places.
P(20s | Chocolate) = ________
P(Chocolate | 30s) * P(Vanilla | 30s) = ________
Answers
P(20s | Chocolate) = 33 / 127 = 0.26 (2dp)
There are 122 people in their 30s 53 liking chocolate and 69 vanilla
P(chocolate | 30s) x P(vanilla | 30s) = 53/122 x 69/122 = 0.25 (2dp)
The probability of P(20s | Chocolate) and P(chocolate | 30s) x P(vanilla | 30s) will be 0.26 and 0.25, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
Adults were polled to determine whether they preferred vanilla or chocolate ice cream. The survey findings for three age groups are displayed in the table.
There are 127 people who enjoy chocolate, and 33 of them are in their 20s is given as,

the interest paid for borrowing qn amount of money for 3yrs at the rate of 4%is n108 find the amount of the money borrowed
Answers
The amount of the money borrowed is 864.941
So the amount of money over time can be given with an exponential function y=a(b)^x or more specifically y=a(1+r)^x where r is the growth rate (interest rate)
So the equation can be written as
m=(1.04)^t
Where m represents the amount of money over time, P represents the principal amount, and t represents time in years. Since we're given the amount of interest paid and not the total amount which includes the initial amount borrowed you have to subtract P from the equation. This will give us the equation that we'll use to find the initial amount
[tex]I=P(1.04)^t-P[/tex] where I represent the interest paid.
plug the values into the equation
[tex]108=P(1.04)^3-P\\P=864.941[/tex]
Therefore the amount of the money borrowed is 864.941.

ΔABC is a right triangle as it possesses a right angle (90°).
Triangle ABC is a right angled triangle since it holds Pythagoras theorem.
What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
For a right angled, triangle, there is a theorem called Pythagoras Theorem which relates the three sides of the triangle.
Pythagoras theorem states that,
Hypotenuse² = Base² + Altitude²
Here AC is the hypotenuse, BC is the base and AB is the altitude.
Base² + Altitude² = (BC)² + (AB)²
= 5² + 12²
= 25 + 144
= 169
= 13²
= AC²
= Hypotenuse²
Pythagoras theorem holds for the given triangle.

Answer: For the first box it is parallel, for the second box it is the corresponding angles theorem, the third is NYM, and the last one is AA.
Step-by-step explanation: 1.) Since line NM has an arrow on it's line and XZ has an arrow on it's line, that means that those two line are parallel to each other. 2.) Since both triangle contain the same transversal line (NY) and the corresponding angles theorem states that if a transversal intersects parallel lines, the corresponding angles are congruent. From this we can conclude that this means that the angle <YXZ has is congruent to the angle <YNM. Therefore we use the corresponding angles theorem. 3.) Answer 2 basically answers box number three but since we concluded that Angles of <YXZ and <YNM are both congruent <NYM would be your answer its just flipped. 4.) We use the AA theorem, because the AA theorem states that if an angle or angle(s) of one triangle is congruent to another angle/angle(s) of another triangle, then the triangles are similar (congruent). Therefore we would use the AA theorem.

Draw a line segment from (-7, -2) to (3, 8)
See the diagram below.
You do not have to draw the blue dashed line. It's there to show how the points reflect over.
=========================================================
Explanation:
The inverse will have us swap x and y. The point (x,y) becomes (y,x)
The endpoint (-2, -7) becomes (-7, -2)
Also (8,3) moves to (3, 8)
Visually, these points are being reflected over the line y = x to form the inverse. We only need to worry about the endpoints because 2 points is the minimum needed to form a straight line.
Check out the diagram below. The red segment is the inverse. The blue dashed line is the line y = x. You don't have to plot this line as it's just a visual tool to see what's going on. Your teacher likely will only want the red segment.
Since the original segment is parallel to y = x, the inverse is also parallel to the mirror line. All three lines are parallel.

What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let the total number of benches be represented by x. If students sit 3 per bench, we are short 3 benches. Therefore, the total number of students can be written as,
Total number of students = 3x + 9
If they sit 5 per bench, 2 benches are left empty, and one bench only has 4 students.
Total number of students = 5(x-1) - 10 +4
Now, the total number of students can be written as,
3x + 9 = 5(x-1) - 10 +4
3x + 9 = 5x - 11
20 = 2x
x = 10
