Answer:
There were 204 ladies and 136 gentlemen in the conference
Step-by-step explanation:
Let's set the variables:
L = number of ladies in the conference
G = number of gentlemen in the conference
We know 340 people participated in the conference, thus:
L + G = 340 [1]
We are also given the ratio of ladies and gentleman as 3:2, thus:
L/G = 3/2
Cross-multiplying:
2L = 3G [2]
From [1]:
L = 340 - G
Substituting in [2]:
2(340 - G) = 3G
Operating:
680 - 2G = 3G
5G = 680
G = 680/5 = 136
G = 136
L = 340 - 136 = 204
L = 204
There were 204 ladies and 136 gentlemen in the conference

If a 200 N net force acts on a 500 grams car, what will the acceleration of the car be?
Answer:
The acceleration of the car will be 400 m/s².
Step-by-step explanation:
The acceleration of the car can be found using Newton second law:
[tex] F = ma [/tex]
Where:
F: is the net force = 200 N
m: is the mass = 500 g
a: is the acceleration =?
Then, the acceleration will be:
[tex] a = \frac{F}{m} = \frac{200 N}{500 g*\frac{1 kg}{1000 g}} = 400 m/s^{2} [/tex]
Therefore, the acceleration of the car will be 400 m/s².

Which expression is equivalent to 4^-5 • 3^-5 ?
The expression equivalent to 4^-5 • 3^-5 is 12^-5
What are equivalent expressions?Equivalent expressions are simply known as expressions with the same solution but different arrangement.
Given the index expressions;
4^-5 • 3^-5
Using the exponent rule, the two values are have different bases but the same exponent and thus, we multiply the bases and leave the exponents the same way.
This can be written as;
4(3) ^ -5

The sum of three consecutive even numbers is 582. What is the 1st number?
Answer:
192
Step-by-step explanation:
Answer: The first number is 192 .
Step-by-step explanation:
Let the three consecutive even numbers
be x , x+2 and x +4 .
Their sum = 582
x + (x+2) + (x+4) = 582
x + x +2 + x +4 = 582
3x + 6 = 582
3x = 582 - 6
3x = 576
x =
x = 192
First number = 192
Second number = 192 + 2 = 194
Third number = 192 + 4 = 196

Lines AAA, BBB, and CCC show proportional relationships.
Which line has a constant of proportionality between yyy and xxx of 333?
The line A has the constant of proportionality between x and y as 5.
What do you mean by constant of proportionality?In mathematics, we use the constant of proportionality to determine the type of proportionality, whether direct or indirect.
The proportionality constant aids in the solution of equations encompassing ratios and proportions.If one quantity increases, other quantity increases, the two quantities are considered to be proportional. Furthermore, as one quantity decreases, so does the other.For, the data given in the question;
Given lines A, B, and C Obtaining the equation for the line yields the proportionality constant.
1) Line A intersects (0,0) and (1, 5). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(5 - 0)/(1 - 0)]×(x - 0)
y = 5x
y/x = 5
The proportionality constant between y and x is 5.
2) Line B traverses (0,0) and (3, 5). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(5 - 0)/(3 - 0)]×(x - 0)
y = 5x/3
y/x = 5/3
The proportionality constant between y and x is 5/3.
3) Line C intersects (0,0) and (3, 2). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(3 - 0)/(2 - 0)]×(x - 0)
y = 3x/2
y/x = 3/2
The proportionality constant between y and x is 2/3.
Therefore, the constant of proportionality between x and y as 5 shown by line A.

An ice cream shop offers 3 ice cream flavors and 3 types of syrup,and 2 toppings for sundaes . How many different ways are there to make a sundae with one ice cream flavor, one type of syrup, and one topping.
Given:
Types of ice cream = 3
Types of syrup = 3
Toppings for sundaes = 2
To find:
The number of difference ways to make a sundae with one ice cream flavor, one type of syrup, and one topping.
Solution:
We have,
Total number of ways to select 1 form 3 ice cream flavor = 3 ways
Total number of ways to select 1 form 3 syrup = 3 ways
Total number of ways to select 1 form 2 toppings = 2 ways
Now, the total number of ways is
[tex]\text{Total ways}=3\times 3\times 2[/tex]
[tex]\text{Total ways}=18[/tex]
Therefore, the total number of difference ways to make a sundae with one ice cream flavor, one type of syrup, and one topping is 18.

5 small bucket and 2 large bucket of water make 20 liter.three small bucket and 2 large bucket make only 18 liter.how much water each bucket hold?
9514 1404 393
Answer:
small: 1 liter; large: 7.5 liters
Step-by-step explanation:
The difference between the two sets of buckets is 2 small buckets and 2 liters. Hence we know that a small bucket is 1 liter.
Then 5 small buckets contribute 5 liters to the 20-liter total. The remaining 15 liters comes from 2 large buckets, so each of those is 7.5 liters.
Large bucket: 7.5 liters
Small bucket: 1 liter

Astrid has her two sons help if they each work at approximately the same rate as Astrid is 23/2 = 11.5
Then 11.5/2 = 5.75 hours.
The work is calculated using the work formula. Let's review what work means before learning the formula. When we apply a force to an item and the object is moved, we say that work has been done. The work done becomes zero if there is no displacement in the direction of the force. Calculating the amount of labor required to move an object is done using the work formula.
