It is given that the glacier is moving at a rate of 0.3 inches every hour. It means the average rate of change is 0.3.
Let d is the total moved distance of glacier and t is number of hours. Then the total moved distance of glacier after t hours is defined as
[tex]d=0.3t[/tex]
At t=1,
[tex]d=0.3(1)=0.3[/tex]
At t=2,
[tex]d=0.3(2)=0.6[/tex]
At t=3,
[tex]d=0.3(3)=0.9[/tex]
At t=4,
[tex]d=0.3(4)=1.2[/tex]
Total moved distance of glacier after 4 hours is 1.2 inches.
The value of x is 1.2. Therefore the correct option is 1.

How would paying off the lowest outstanding balance credit card first be beneficial over paying off the one with the highest interest rate?
Paying off the lowest outstanding balance credit card first can be beneficial for motivation and momentum, even if it's not the most mathematically efficient approach.
Explanation:When paying off credit card debt, it can be beneficial to start by paying off the credit card with the lowest outstanding balance. This approach is called the Snowball Method and is popularized by financial expert Dave Ramsey. The Snowball Method focuses on tackling the smallest debt first, regardless of the interest rate, as it provides a psychological boost and motivates individuals to continue paying off their debts.
By paying off the smallest debt first, you can quickly eliminate one of your credit card balances. This can give you a sense of accomplishment and momentum to continue paying off your other debts. It's important to note that while the Snowball Method may not be the most mathematically efficient approach in terms of saving on interest payments, it can be effective in helping individuals stay motivated and committed to paying off their debts.

The volume, V, of a soap bubble is related to its surface area, A. In cubic centimeters, this relationship is shown by the formula V = 0.094A 3/2. What is the surface area of a bubble with a volume of 5 cm3 ?
The surface area of a soap bubble with a volume of 5 cm³, given the relationship V = 0.094 [tex]A^{3/2[/tex], can be calculated by rearranging and solving the formula, resulting in an approximate surface area of 36.3 cm².
To find the surface area of a soap bubble with a volume of 5 cm³, using the given relationship V = 0.094 [tex]A^{3/2[/tex], we need to rearrange the formula to solve for A (the surface area). We will take the following steps to find A:
First, divide both sides of the equation by 0.094 to isolate [tex]A^{3/2[/tex] on one side:
[tex]A^{3/2[/tex] = V / 0.094
Next, substitute V = 5 cm³ into the equation:
[tex]A^{3/2[/tex] = 5 / 0.094
Calculate the right-hand side:
[tex]A^{3/2[/tex] ≈ 53.19
Finally, raise both sides of the equation to the power of 2/3 to solve for A:
A = [tex](53.19)^{2/3[/tex]
Calculating the right-hand side gives us the surface area A. After performing these calculations, we find that the surface area of a bubble with a volume of 5 cm³ is approximately 36.3 cm².

Final answer:
The measure of dispersion which is not measured in the same units as the original data is the variance.
Explanation:
The measure of dispersion which is not measured in the same units as the original data is the variance. The variance is a squared measure and does not have the same units as the data. On the other hand, the standard deviation is derived from the variance and it measures the spread in the same units as the data.
Then again, the standard deviation, which is the square foundation of the fluctuation, is estimated in similar units as the first information. It gives a proportion of the spread of the information that is all the more effectively interpretable. The middle is a proportion of focal inclination and doesn't give data about the scattering or spread of the information.
The coefficient of assurance, otherwise called R-squared, is a proportion of how well the relapse line fits the information and isn't straightforwardly connected with scattering.
Group of kids rode horses to canyon. 20 eyes 30 legs between them. How many horses
Final answer:
To solve this problem, we set up equations based on the total number of eyes and legs. By solving the system, we find that the group consists of 5 horses.
Explanation:
The question asks us to solve a problem involving a group of kids and horses by using the given information about the total number of eyes and legs. Since humans have two eyes and two legs, and horses have two eyes and four legs, we can set up a system of equations to find the solution.
Let's denote the number of kids as 'k' and the number of horses as 'h'. Since each human and horse has two eyes, the total number of eyes is given by the equation: 2k + 2h = 20. Similarly, the total number of legs is given by the equation: 2k + 4h = 30. Solving these equations will give us the number of kids and horses in the group.
Solving for 'k' from the first equation gives us k = 10 - h. Substituting this into the second equation gives us 2(10 - h) + 4h = 30. Simplifying this equation results in 20 - 2h + 4h = 30, which further simplifies to 2h = 10, and thus h = 5. Therefore, there are 5 horses in the group.

The formula represents the surface area S of a cube with side lengths x.
S=6x^2
Solve for x.
The solution of x is √(S/6).
The formula to find the surface area of a cube with side lengths x is:
S = 6x2
To solve for x:
Divide both sides by 6: S/6 = x2
Take the square root of both sides to isolate x: x = √(S/6)

Calculus HELP PLEASE? A highway runs due north. A car traveling at 50 mph exits the highway at a 30° angle. After driving another 1.5 hours at the same speed and direction, how far away is the car from the highway?
Answer:
37.5 miles is the answer.
Step-by-step explanation:
Since car is travelling with a speed = 50 mph
Angle between the highway and the track on which the car is travelling = 30°
Now we know sin∅ = distance between highway and the car/Distance traveled by the car on the new track
Distance traveled by the car in 1.5 hours = speed × time
= 50 × 1.5 = 75 mi.
Therefore sin 30° = x/75
x = 75×sin30° = 75 × 1/2 = 37.5 mi.
Therefore the answer is 37.5 mi away.

The price of 6 pretzels is $5.10. Simon and Sofia bought 8 pretzels an shared the cost equally. How much did each person pay?
Answer:
$3.40
Step-by-step explanation:
To find out the amount each person paid, let's find the total cost of the pretzels first.
6 pretzels ----- $5.10
1 pretzel ----- $5.10 ÷6= $0.85
8 pretzels ----- 8($0.85)= $6.80
The total cost of 8 pretzels is thus $6.80.
Since the total cost was shared equally amongst two people, each person paid half of the total cost.
Amount each person paid
= $6.80 ÷2
= $3.40
By taking a quotient between the total cost and the number of people, we can see that each one pays $3.40
How much did each person pay?We know that the price of 6 pretzels is $5.10, then the price for each pretzel is given by the quotient:
$5.10/6 = $0.85
We know that Simon and Sofia bought 8 pretzels, so they pay:
P = 8*$0.85 = $6.80
And they divide that evenly between the two, so we can take the quotient:
p = $6.80/2 = $3.40
That is the amount that each person pays.

An angle measures 72° less than the measure of a complementary angle. What is the measure of each angle?
Answer: [tex]81^{\circ}\ \text{ and }\ 9^{\circ}[/tex]
Step-by-step explanation:
We know that the sum of two complementary angles is [tex]90^{\circ}[/tex].
Given : An angle measures 72° less than the measure of a complementary angle.
Let x be the angle , then the measure of other angle will be x-72.
Since they area complementary , then we have
[tex]x+x-72=90\\\\\Rightarrow\ 2x=90+72\\\\\Rightarrow\ 2x=162\\\\\Rightarrow\ x=\dfrac{162}{2}=81[/tex]
Therefore, the measure of angles are :
[tex]81^{\circ}\ \text{ and }\ (81-72)^{\circ}=9^{\circ}[/tex]
