Sara's change in elevation is calculated by multiplying 4 hours by -8 meters/hour. This gives a total change in elevation of -32 meters, which shows that Sara descended 32 meters from her starting point.
Explanation:The subject of your question is math, specifically dealing with the concept of multiplication. To determine Sara's change in elevation, we have to know how much the elevation decreases each hour. It's important to note that the decrease in elevation is the same as saying Sara is descending, thus the change will be represented by a negative number.
In this case, for every hour Sara hiked, her elevation decreased by 8 meters. Therefore, the total change in elevation after 4 hours would be 4 hours multiplied by -8 meters/hour. The calculation for this is:
4 hours * -8 meters/hour = -32 meters
Therefore, Sara hiked down a total of 32 meters from her starting point on the mountain.

the rules of a contest say that there is a 5% chance of winning a prize. four hundred people enter the contest. predict how many people will win a prize
A percentage is a way to describe a part of a whole. The number of winners in the contest is 20.
What is the Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the chances of winning a prize are 5%, and 400 people enter the contest, therefore, the number of people who will be winning is 5% of the number of contestants.
[tex]\text{Number of Winner} = 5\%\ \text{of the Number of Contestants}\\\\\text{Number of Winner} = \dfrac{5}{100} \times 400 = 20[/tex]
Hence, the number of winners in the contest is 20.

What is the equivalently non equivalent
Answer:
1/2 and 5/8 are not equivalent
Explanation:
The term equivalent means that a number or term has the same numerator-to-denominator (proportional) ratio as another number.
1/2 and 2/4 would be equivalent because if you divide the numerator and the denominator of the second fraction by 2, the result is the 1/2.
If you divide the denominator of 5/8 by 4, the result is a 2, matching the denominator of 1/2. However, if you divide the numerator by 5, the result is 1.25, which does not match the numerator of 1/2.
Therefore, these two numbers are not equivalent.

If they played 43 games, how many did they lose?
If they played 43 games, the number of games that they lost is: 32
How to save algebra word problems?
Let
x represent number of games won
Let y represent number of lost games.
Thus;
y = 4x - - - - - equation (I)
Let z denote tied games.
Thus;
z = x - 5 - - - - - equation(II)
Total games played is 43.
Thus;
x + y + z = 43 (III) equation
substitute (I) and (II) in (III)
therefore
x+(4x)+(x-5)=43

The length of a rectangle is 5/2 units greater than twice its width. If its width is w, which expression gives the perimeter of the rectangle in terms of w?
Answer:
D: 6w + 5
Step-by-step explanation:
The perimeter of a rectangle can be calculated as follows:
Perimeter = 2(width + length)
We are given that:
width = w units
length is 5/2 units greater than twice the width. This means that:
length = 2w + 5/2
Now, substitute in the above equation to get the expression for the perimeter as follows:
Perimeter = 2(width + length)
Perimeter = 2(w + 2w + 5/2)
Perimeter = 2(3w + 5/2)
Perimeter = 2(3w) + 2(5/2)
Perimeter = 6w + 5

Factor the quadratic expression Completely; -8x^2-15x+2
Answer:
(x + 2)(-8x + 1) or,
(-8x + 1)(x + 2)
Explanation:
To factor quadratic equations in the form ax² + bx + c that cannot be factored in your head, the first step is to find factors for the product of coefficient a and constant c whose sum equates to coefficient b. This may sound confusing, but it is easier in practice.
So, we find the product of -8 and 2 which is -16.
Now we list the factors of -16. I like to list them as factor pairs. These are:
1, -16, 2, -8, 4, -4, 8, -2, 16, -1
Next, we examine which combination of factor pairs has a sum of -15. These are -16 and 1. To check: -16 + 1 = -15
Then, we place these values as coefficients into the original equation as substitutes for -15x and find factor out the greatest common factor (GCF) of the equation terms:
-8x² - 16x + x + 2
(-8x² - 16x) + (x + 2)
The GCF between -8x² and -16x is -8x. The GCF between x and 2 is 1.
-8x(x + 2) + 1(x + 2)
If these binomials within the parenthesis match, then you have found the factors. The binomial within the parenthesis is one factor and the GCFs outside of each binomial are is the other factor. Thus, the factors of the original quadratic expression are:
(-8x + 1)(x + 2)
To check these factors for accuracy, we can use the FOIL method to expand the expression, combine like terms, and observe if it matches the original equation. FOIL stands for Firsts, Outsides, Insides, and Lasts, instructing which terms of each binomial are multiplied together.
Firsts: -8x(x) = -8x²
Outsides: -8x(2) = -16x
Insides: 1(x) = x
Lasts: 1(2) = 2
In an equation: -8x² - 16x + x + 2 → -8x² - 15x + 2
This is the original equation, therefore (-8x + 1)(x + 2) are accurate factors.
