The question is about ratios. Based on the condition, Elijah invited twice as many boys as girls which makes up a total of 18 people. We find out that Elijah invited 6 girls and 12 boys.
Explanation:This is a mathematical problem dealing with ratios. From the question, we know that Elijah plans to invite twice as many boys as girls, and the total number of guests will be 18 people.
Assume the number of girls Elijah is inviting is x. Therefore, the boys will be 2x (twice the number of girls).
Now, we form an equation which is the total number of people: x (girls) + 2x (boys) = 18. Solving for x, we get x = 6. So Elijah is inviting 6 girls and 2*6 = 12 boys.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Teo worked for 42.5 h at $70.75 per hour.
Let x be the total earnings.
The value of x can be found as follows:
x = 42.5(70.75)
x = 3006.875
Or
x = 3006.88
Thus, the total earning for Teo is $3006.88 if teo worked for 42.5 h at $70.75 per hour, the answer is 3006.88.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of donuts made be = A
The number of donuts made initially = 30 donuts
The time taken by the chef to make 30 donuts = 60 minutes
So , the equation will be
The number of donuts = 90 donuts
The number of donuts = 3 x initial number of donuts
So , the time taken by the chef to make 90 donuts is =
3 x time taken by the chef to make 30 donuts
And , the equation is
The time taken by the chef to make 90 donuts = 3 x 60 minutes
The time taken by the chef to make 90 donuts = 180 minutes
Therefore , the time taken by the chef is 180 minutes or 3 hours
Hence ,

All of our employees speak at least 2 languages and many of them (45%) speak 3. We have even got few (8%) persons, that speak 4 languages.
What is the average number of languages spoken at our team?
The average number of languages spoken by the employees is calculated as a weighted average and equals 2.61.
To determine the average number of languages spoken by the employees, we need to calculate the weighted average. This takes into account the percentage of people speaking a different number of languages. Let's denote the number of languages spoken as L, and the percentage of people speaking that many languages as P.
According to the information provided, we have the following groups:
People who speak 2 languages, which is 100% - 45% - 8% = 47% of the employees.People who speak 3 languages, which is 45% of the employees.People who speak 4 languages, which is 8% of the employees.Now, we calculate the average with the formula:
Average = (L1 * P1 + L2 * P2 + L3 * P3) / 100
Where:
L1 = 2 languagesL2 = 3 languagesL3 = 4 languagesP1 = 47%P2 = 45%P3 = 8%Substituting the values we get:
Average = (2 *47 + 3 * 45 + 4 * 8) / 100
Average = (94 + 135 + 32) / 100
Average = 261 / 100
Average = 2.61
So, the average number of languages spoken by the employees is 2.61.

Calculate the kinetic energy of an 88-kg scooter moving at 18 m/s .
Answer:
kinetic energy of the scooter is 14256 joule.
Step-by-step explanation:
Since kinetic energy of an object is represented by the formula
Kinetic energy = [tex]\frac{1}{2}(\text{Mass})(\text{Velocity}^{2})[/tex]
Mass of the scooter = 88 kg
Velocity of the scooter = 18 meter per second.
Kinetic energy = [tex]\frac{1}{2}\times 88\times (18)^{2}[/tex]
= 44×(18)²
= 14256 Joule
Therefore, kinetic energy of the scooter is 14256 joule.

What is the product of 3/4x1/3x2/5
Final answer:
To find the product of 3/4, 1/3, and 2/5, multiply the numerators to get 6 and the denominators to get 60, resulting in 6/60. This simplifies to 1/10.
Explanation:
The question asks us to find the product of the three fractions: 3/4, 1/3, and 2/5. To calculate this, we multiply the numerators together and then the denominators together:
Numerators: 3 times 1 times 2 = 6
Denominators: 4 times 3 times 5 = 60
Therefore, the product of 3/4, 1/3, and 2/5 is:
6/60, which can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 6. This gives us 1/10.

The quotient of x and 7 is equal to 13. Define variable and then write an expression to model the situation
Final answer:
The expression for the given situation "The quotient of x and 7 is equal to 13" is modeled by the linear equation x/7 = 13. By multiplying both sides by 7, we find that x equals 91.
Explanation:
The question "The quotient of x and 7 is equal to 13" can be modeled as an expression in the form of a linear equation. To define variables in this context, we let x represent the unknown number we're trying to find. The quotient of x and 7 means x divided by 7, and this is equal to 13. Therefore, we can write the linear equation as x/7 = 13.
To solve for x, we perform algebraic operations. We multiply both sides of the equation by 7 to get rid of the denominator. The expression becomes 7 * (x/7) = 13 * 7, which simplifies to x = 91.

They y intercept of a function f(x) is (0,b) what is the y intercept of f(x)=k
The function f(x)=k represents a horizontal line where 'k' is the y-intercept. This means the line crosses the y-axis at the point (0,k).
Explanation:The function f(x)=k represents a horizontal line across the y-axis at the value of 'k'. In this case, the y-intercept or 'b' would also be 'k', given that regardless of the x-value, the output will always be 'k'. The point of intersection with the y-axis is thus (0,k).
In general, for the linear equation y=mx+b, 'm'
represents the slope of the line and 'b' is the y-intercept where the line crosses the y-axis. In this case, 'm' would be zero as the slope of a horizontal line is 0, causing the line's equation to simplify to
y=k, or f(x)=k. This indicates that for every x, the y value remains constant at 'k' .
