A woman 5-feet tall casts an 8-foot shadow. at the same time of day, the shadow of a tree nearby is 120 feet long. in feet, 75 feet tall is the tree.
Let the tree height = x
From the question, we have
5/8 = x/120
x = (5*120)/8
x = 75 feet
Tree height = 75 feet

8. Determine the perimeter of Parallelogram STUV.
Round to the nearest hundredth, if necessary.
The answer to this Question Based on Perimeter is 8.72
What is Perimeter?
Perimeter is total length of boundary of any closed figure
Solution:
to calculate perimeter of this first we need to calculate the lengths of all sides
BY pythagoras theorem we can see that SV = sqrt(4^2 + 1^2)
SV = sqrt(17)
By similar procedure other lengths we can calculate as
UV = sqrt(5)
UT = sqrt(17)
ST = sqrt(5)
Hence perimeter will be sum of all these that is 2sqrt(5) + 2sqrt(17)
2(2.24) + 2(4.12)
4.48 + 4.24
8.72 will be perimeter

using substitution to solve the system below, what expression should be substituted into the first equation?
The expression should be substituted into the first equation is "x = 8 -2y" and also the value of x = 3 and y = 2.5
What do you mean by substitution?
The substitution method is an algebraic strategy for resolving simultaneous linear equations. This approach, as the name suggests, involves substituting the value of one variable from one equation into the second equation. This makes it easier to answer a pair of linear equations by combining them into a single equation with a single variable.
The equations given in the question,
2x - 4y = -4
x + 2y = 8
Let these two equation be named as 1 and 2 respectively.
Taking equation 2 and making x stay one side and all others on other side of the equation. We get,
x = 8 -2y
Substituting this value of x in equation 1.
2x - 4y = -4
2(8 - 2y) - 4y = -4
y = 2.5
substituting this value of y in equation 2,
x + 2y = 8
x = 8 - 5
x = 3
Therefore, The expression should be substituted into the first equation is "x = 8 -2y" and also the value of x = 3 and y = 2.5

a regression model in which more than one independent variable is used to predict the dependent variable is called
A regression model in which more than one independent variable is used to predict the dependent variable is called multiple linear regression.
Multiple linear regression refers to a statistical technique used to predict the outcome of one variable based on the values of two or more variables. Sometimes simply called multiple regression, it is an extension of linear regression. The variable we want to predict is called the dependent variable, and the variables we use to predict the value of the dependent variable are called the independent or explanatory variables.
Multiple Linear Regression - Formula
Yi + β0 + β1xi1 + β2xi2 + βpxip + ∈
Where:
Yi is the dependent or predicted variable
β0 is the y-intercept, i.e., the value of y when both xi and x2 are 0.
β1 and β2 are the regression coefficients representing the change in y relative to a one-unit change in xi1 and xi2, respectively.
βp is the slope coefficient for each independent variable.
∈ is the model’s random error (residual) term.

Melinda can paint 14 of a wall in the same time that desiree can paint 25 of a wall. How much of a wall will melinda have painted when desiree has finished painting 1 wall?.
Melinda will have painted 56 percentage of a wall for the time taken by Desiree, when she has finished painting 1 wall.
The computation of the difference between the time taken by Desiree and Melinda to paint walls at their respective speeds can be shown using the generalized calculations, as expressed hereunder,
Desiree will take 4x the time for painting 1 wall completely (25x4=100%). Thus, the amount of time taken by Melinda will also be 4x of her actual time, as below,
14×4= 56%
Therefore, Melinda will have covered 56 percent of the wall in the time when Desiree completes painting the entire wall.

Using the percentage by volume of the solutions, we can calculate that we require 216 mL of 100% alcohol and 384 mL of 50% alcohol.
What is the percentage by volume?Volume/volume percentage is a unit used to represent how much of a substance is present in a solution.
It is sometimes referred to as v/v percent or %v/v.
It is calculated by dividing the volume of the solute by the total volume of the solution, then multiplying the result by 100.
So, we are aware of:
A + B = 600 mL
We also know that the total alcohol concentration of the final solution must be equal to:
0.68 * 600 mL = 408 mL
Therefore, it follows that:
0.50 * A + B = 408 mL
The first equation leads to the following conclusion:
A = 600 mL - B
Using that A in the second equation, we arrive at:
0.50 * (600 mL - B) + B = 408 mL
300 mL - 0.50 B + B = 408 mL
If we rewrite this equation as follows:
B - 0.50 * B = 408 mL - 300 mL
0.50 * B = 108 mL
B = 108 mL / 0.50
B = 216 mL
A = 600 mL - 216 mL = 384 mL
Therefore, using the percentage by volume of the solutions, we can calculate that we require 216 mL of 100% alcohol and 384 mL of 50% alcohol.

According to the given image, the given function is increasing at (C) x > 2.
What are functions?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.
The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
The relationship between the input or domain and the output or range is known as the function rule.
If and only if there is a single value in the range for each domain value, a relation is a function.
A function is denoted by the notation f x, where x is the input value.
A function has the general form y = f x.
So, let's consider the given image:

The domain of a function is the set of numbers that can go into a given function.
The set of input values (x) for which a function generates an output value is known as the domain of the function (y).
we can write [tex]y = f(x).[/tex]
domain is the full set of x-values that can be plugged into a function to produce a y-value.
The most effective approach to finding a domain will depend on the type of function.
The domain is expressed using an open bracket or parenthesis, the domain's two endpoints separated by a comma, and then a closed bracket or parenthesis.
To find domain of function we should know the property of that function like what the function can take inside it.
