As shown, Suzi starts her hike at an elevation below sea level.whaen she reaches the end of the hike,she still below sea level at -127 feet. What was the change in elevation from the beginning of suzi's hike to the end
(Current elevation: -225 feet )
Current Position of Suzi below Level = -225 Feet
Now, Suzi Started her Hike
Position of Suzi after taking Hike from her initial Position= -127 feet
The change in elevation from the beginning of suzi's hike to the end
= -127 -(-225)
= -127 +225
= 98 feet
The change in elevation from the beginning of suzi's hike to the end=98 feet

Select the correct scientific notation form of this numeral using only 2 significant figures. 482.65
To write 482.65 in scientific notation with two significant figures, round the number to 480 and move the decimal point two places to the right, resulting in 4.8 x 10^2.
Explanation:To write the given number 482.65 in scientific notation with two significant figures, we first determine the number of significant figures in the original number, which is five. Since we need to express it in two significant figures, we round the number to 480. Then, we move the decimal point to the right until we have a number between 1 and 10. In this case, we need to move it two places to the right, resulting in the scientific notation form of 4.8 x 10^2.

Which graph represents the solution set of the system of inequalities?
−3x+y>1
y≥x−1
Answer:
Option D is the correct choice.
Step-by-step explanation:
We have been given a system of inequalities. We are asked to choose the graph that represents solution set of the given system.
[tex]-3x+y>1[/tex]
[tex]y\geq x-1[/tex]
The boundary line of [tex]-3x+y>1[/tex] will be a dotted line as it has a [tex]>[/tex] sign. The boundary line of this inequality will cross y-axis at point (0,1) and will have a slope of 3.
The boundary line of [tex]y\geq x-1[/tex] will be a solid line as it has a [tex]\geq[/tex] sign. The boundary line of this inequality will cross y-axis at point (0,-1) and will have a slope of 1.
Now, we will check point (0,0) in both inequalities to find the shaded region.
[tex]y\geq x-1[/tex]
[tex]0\geq 0-1[/tex]
[tex]0\geq -1[/tex]
Point (0,0) satisfies inequality [tex]y\geq x-1[/tex], so shaded region will be area including point (0,0)
[tex]-3(0)+0>1[/tex]
[tex]0+0>1[/tex]
[tex]0>1[/tex]
Point (0,0) doesn't satisfy inequality [tex]-3x+y>1[/tex], so shaded region will be area excluding point (0,0).
The solution set of given system of inequalities will be area of included in both inequalities.
We can see that last option is the correct choice as it has one dotted line (y-intercept 1) and one solid line (y-intercept -1).
Therefore, option D is the correct choice.
Answer:
The bottom choice one the right is correct

A popular chain of superstores made 3.0479×108 dollars in profit last year. One particular store in the chain made 2.102×106 dollars in profit last year.
How many times greater is the profit made by the entire chain last year than by this particular store?
Drag and drop the values into the boxes to represent the answer in scientific notation
0.145 1.45 145 10^2 10^14 10^48
_____ x _____ Greater
We have been given that a popular chain of superstores made [tex]3.0479\text{x}10^{8}[/tex] dollars in profit last year. Also, we know that one particular store in the chain made [tex]2.102\text{x}10^{6}[/tex] dollars in profit last year.
Now, in order to figure out how many times greater is the profit made by the entire chain last year than by this particular store, we will divide the profit made by the entire chain by the profit made by the given particular store.
[tex]\frac{3.0479\text{x}10^{8}}{2.102\text{x}10^{6}}=\frac{3.0479}{2.102}\text{x}10^{8-6}=1.45\text{x}10^{2}[/tex]
Therefore, the required answer is: [tex]1.45\text{x}10^{2}[/tex]

2m-nx=x+4
Solve for x
The solution is x = (2m - 4) / (n + 1).
To solve the equation 2m - nx = x + 4 for x, we need to collect all the x terms on one side of the equation. Here are the steps to do that:
Start by subtracting x from both sides of the equation to get 2m - nx - x = 4.
Next, combine like terms by adding -nx and -x together to get 2m - (n+1)x = 4.
Now, solve for x by dividing both sides of the equation by -(n+1) to isolate x.
The solution is x = (2m - 4) / (n + 1).
This is how you solve for x when dealing with linear equations with variables on both sides. The key is to isolate the variable you are solving for by using inverse operations and keeping the equation balanced

A horse ran 800 meters in 40 seconds, 1,200 meters in 60 seconds,and 480 meters in 24 seconds. Is this a proportional relationship? If so, what is the constant of proportionality? What does it represent. Write an equation to represent the distance d , in meters, that the horse runs in t seconds
The given data is in proportion. Therefore, an equation to represent the distance d ,in meters, that the horse runs in t seconds is d=20t.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Given that, a horse ran 800 meters in 40 seconds, 1,200 meters in 60 seconds and 480 meters in 24 seconds.
Here,
800/40 =20, 1200/60 =20 and 480/24=20
Now, in proportional relationship d∝t
d=kt
800=k×40
k=20
d=20t
The given data is in proportion. Therefore, an equation to represent the distance d ,in meters, that the horse runs in t seconds is d=20t.
