Alex is mowing a 145.5 square feet law. He used 3/4 gallon of as to mow 3/10 of the law. How many gallons of gas are needed to mow the entire lawn?
Answer:
2.5 gallons of gasStep-by-step explanation:
Note : we have a proportional relationship between the two variables
_______________________________________
He used 3/4 gallon of gas to mow 3/10 of the lawn
Then
He has to use 1/4 gallon of gas in order to mow 1/10 of the lawn
( we divided both sides by 3)
Then
He has to use 10 × 1/4 gallons of gas to mow 10/10 of the lawn
What that means is :
He has to use 10/4 gallons of gas to mow the entire lawn
In other words :
He has to use 2.5 gallons of gas to mow the entire lawn

What is exponential regression equation?The equation of an exponential regression model takes the following form: y = abˣ where: y: The response variable x: The predictor variable a, b: The regression coefficients that describe the relationship between x and y.
Given is a table, we need to determine the exponential regression equation, for the same,
So,
The general exponential regression equations is, y = abˣ
where, a is initial value and b is growth factor.
Using graph calculator, we get,
a = 3.53
b = 4.37
Put the value of a and b in general equation, to find the exponential regression equation.
y = 3.53(4.37)ˣ

eggs in each case. How many eggs were ordered all together?
The solution is 240 eggs
The total number of eggs ordered by Camp Copeland is 240 eggs
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 equation be represented as A
Now , the value of A is
Let the number of cases ordered by Camp Copeland be = 20 cases
Let the number of eggs in each case = 12 eggs
So , the equation will be
The number of eggs in 20 cases A = 20 x number of eggs in each case
Substituting the values in the equation , we get
The number of eggs in 20 cases A = 20 x 12
The number of eggs in 20 cases A = 240 eggs
Therefore , the value of A is 240 eggs
Hence , the number of eggs is 240 eggs

Vada places a box of toys and a box of books together. The box of toys has a length of 5 feet, a width of 3 feet, and a height of 2 feet. The box of books has a length of 6 feet, a width of 4 feet, and a height of 2 feet. What is the combined volume of the boxes?
Answer:
78 ft cubed
Step-by-step explanation:
First calculate the volume of the toys...
5 x 3 x 2 = 30
Now the book boxes...
6 x 4 x 2 = 48
30 + 48 = 78
The combined volume should be 78 feet cubed! hope this helps!!!
Answer:
78 ft³
Step-by-step explanation:
Volume of a rectangular prism = length × width × height
Toy Box
length = 5 ftwidth = 3 ftheight = 2ft⇒ volume = 5 × 3 × 2 = 30 ft³
Book Box
length = 6 ftwidth = 4 ftheight = 2 ft⇒ volume = 6 × 4 × 2 = 48 ft³
Total combined volume = 30 + 48 = 78 ft³

The probability of picking a chocolate-covered cherry is 0.
The probability that an a fell on the floor is 0.08
The probability that an a or a o would be picked is 0.36
The probability a girl would be picked is 1.
What is the probability?
Probability is used to calculate the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of picking a chocolate-covered cherry is zero because there is no chocolate-covered cherry in the bag.
The probability that an a fell on the floor = number of a in the letter / total number of letters
= 1/13 = 0.08
The probability that an s or a o would be picked is = (number of s in the letter / total number of letters) + (number of 0 in the letter / total number of letters)
= 4/11 + 0 = 4/11 = 0.36
The probability a girl would be picked is one since its an all-girls school.

Evaluate the expression when x = -1 and y = 4. Please give your answer in its most reduced form
Step-by-step explanation:
x = -1, y = 4 We know that, the equation of perpendicular form is x/a + y/b = 1, -1/a + 4/b = 1, -1b + 4a/ab = 1, -1b + 4a = ab, 4a - 1b = ab
For the function f (x) = 4x - e determine
X such that f (x) 0
Answer:
derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the result is the slope of the original function y = f (x).
There are many different ways to indicate the operation of differentiation, also known as finding or taking the derivative. The choice of notation depends on the type of function being evaluated and upon personal preference.
Suppose you have a general function: y = f(x). All of the following notations can be read as "the derivative of y with respect to x" or less formally, "the derivative of the function."
f'(x) f' y' df/dx dy/dx d/dx [f(x)].
[HINT: don't read the last three terms as fractions, read them as an operation.
For example, read: " dx/dy = 3x"
As: "the function that gives the slope is equal to 3x"
Let's try some examples. Suppose we have the function : y = 4x3 + x2 + 3.
After applying the rules of differentiation, we end up with the following result:
dy/dx = 12x2 + 2x.
How do we interpret this? First, decide what part of the original function (y = 4x3 + x2 + 3) you are interested in. For example, suppose you would like to know the slope of y when the variable x takes on a value of 2. Substitute x = 2 into the function of the slope and solve:
dy/dx = 12 ( 2 )2 + 2 ( 2 ) = 48 + 4 = 52.
Therefore, we have found that when x = 2, the function y has a slope of + 52.
Now for the practical part. How do we actually determine the function of the slope? Almost all functions you will see in economics can be differentiated using a fairly short list of rules or formulas, which will be presented

The demand function for the shirts of a concert-promoting company which has been selling an average of 175 T-shirts at performances for $23 each is y=175-6.08x.
What is demand function?The demand function is the function

Here, Q is linear demand curve, a factor which influence the demand, b is slope and P is price.
A concert-promoting company has been selling an average of 175 T-shirts at performances for $23 each. Thus, the total selling price is,
[tex]P=175\times23\\P=4025[/tex]
The company estimates that for each dollar that the price is lowered, an additional 25 shirts will be sold. Thus, the total number of
