A Car Travels m miles in t hours express its average speed algebraically
Answer:
speed = [tex]\frac{m}{t}[/tex]
Step-by-step explanation:
using the formula that relates distance/ speed/ time
distance = speed × time
hence speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{m}{t}[/tex]
Final answer:
The average speed is calculated by dividing the total distance traveled by the total time taken. In algebraic form for a car traveling m miles in t hours, the average speed is V_avg = m / t.
Explanation:
To express the average speed algebraically, we can use the formula for average speed which is the distance traveled divided by the time of travel. In algebraic terms, if a car travels m miles in t hours, the average speed would be represented as:
Vavg = m / t
Here, Vavg represents the average speed, m is the total distance in miles, and t is the time taken in hours. To demonstrate this with an example, if a car travels 150 kilometers in 3.2 hours, its average speed is calculated by dividing 150 km by 3.2 h, which gives an average speed of 47 km/h.

Find the measures of the angles of a right triangle where one of the two acute angles measures 5 times the other
Answer:
Since it is a right angle, you know that the angle measures 90 degrees. Since one acute angle measures 5x (times) the other, you would set it up in equation format as 5x + x = 90.
5x + x = 6x, so
6x = 90
you divide both both sides by 6 (90/6) = 15
To find the measure of the angle that is 5x (times) the other, you do 5(15) = 75 degrees and the other angle is 15 degrees, which adds up to 90 degrees.

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.

Final answer:
The nth term of the geometric sequence 5, 10, 20, 40 is given by the formula T_n = 5 × 2ⁿ⁻¹.
Explanation:
To write an equation for the nth term of the geometric sequence 5, 10, 20, 40, we need to determine the first term (a) and the common ratio (r). In this sequence, the first term a=5 and the common ratio r can be found by dividing the second term by the first term (r=10/5=2).
The formula for the nth term (Tn) of a geometric sequence is given by Tn = a × rⁿ⁻¹.
So, for the given sequence, the nth term can be expressed as:
Tn = 5 × 2ⁿ⁻¹.

Rewrite the expression without using a negative exponent.
Simplify your answer as much as possible.
Answer:
[tex]\frac{n^4}{4}[/tex]
or
[tex]\frac{1}{4} n^4[/tex]
Step-by-step explanation:
The given expression is
[tex]\frac{1}{4n^{-4}}[/tex]
This is an exponential expression with a negative index in the denominator.
We can rewrite the expression so that it will be,
[tex]=\frac{1}{4}\times \frac{1}{n^{-4}}[/tex]
We now apply this property of indices. A negative index in the denominator becomes a positive index in the numerator.
[tex]\frac{1}{a^{-m}} =a^{m}[/tex]
When we apply this we get,
[tex]=\frac{1}{4}\times n^{4}[/tex]
We then simplify to obtain,
[tex]=\frac{1}{4}n^{4}[/tex]
Final answer:
To rewrite an expression without a negative exponent, take the reciprocal of the base with the positive exponent. Division of exponentials requires dividing coefficients and subtracting exponents of the same base. Eliminate negative exponents and simplify the expression to get the final result.
Explanation:
To rewrite an expression without a negative exponent, you simply take the reciprocal of the base and use the positive exponent. For example, seeking to rewrite x-n, you would transform it into 1/xn, moving the base x to the denominator and making the exponent positive.
Division of exponentials involves simplifying expressions by dividing the coefficients and subtracting exponents when the bases are the same. For instance, for expressions like am / an, the result would be am-n. In case there are numerical coefficients in front, divide those numbers directly. After simplifying, always check whether the answer makes sense and is in the simplest form.
Working with negative exponents, it's crucial to eliminate terms that result in a more straightforward expression and confirm that no negative exponents remain in the final answer, ensuring it is in its acceptable form.

what is the answer to this using either substitution or elimination?
The system of equations x+y=154 and x+4y=10, can be solved by substitution method giving the solution x = 202 and y = -48.
Explanation:This question is similar to other problems in algebra where you are given a system of equations. In this case, you have the equations x+y=154 and x+4y=10. We will solve this problem using substitution.
First, let's isolate x in the first equation: x = 154 - y.
Next, we will substitute (154-y) for x in the second equation: (154 - y) + 4y = 10. Simplifying this equation, we get 3y = -144, so y = -48.
Substitute back y = -48 into the first equation, we have x + (-48) = 154, which means x = 202.
So, the solution of the system is: x = 202, y = -48.

Find the larger of two consecutive integers if the larger is 149 less than twice the smaller.
Answer:
151
Step-by-step explanation:
Let x = the smaller integer and y = the larger integer.
We have two conditions:
(1) x + 1 = y
(2) y = 2x - 149 Substitute (1) into (2)
x + 1 = 2x - 149 Add 150 to each side
x + 150 = 2x Subtract x from each side
x = 150 Substitute into (1)
150 +1 = y
y = 151
The larger integer is 151.
Check:
(1) 150 + 1 = 151
151 = 151
(2) 151 = 2×150 -149
151 = 300 -149
151 = 151
Final answer:
The larger of the two consecutive integers is 151, determined by setting up an algebraic equation based on the given condition and solving for the smaller integer first.
Explanation:
The student is asked to find the larger of two consecutive integers given that the larger is 149 less than twice the smaller. Let's denote the smaller integer as n. Thus, the larger integer would be n + 1. According to the problem, we have the equation (2n) - 149 = n + 1, which simplifies to n = 150, making the larger integer 151.

It takes you 5 hours to complete a 375 kilometer trip. What was your average speed on this trip? Henry takes a boat ride for 15 minutes to reach his destination. If the boat was traveling at 6 meters/second, how far did the boat travel? A storm is moving east towards your house at an average speed of 35 km/hr. If the storm is currently 80 kilometers from your house, in how much time do you expect it to arrive? If the velocity of an object changes from 15 m/s to 50 m/s during a time interval of 4 s, what is the acceleration of the object? If the acceleration in problem 4 is constant, what's the average velocity of the object in the previous problem? Using the information provided and calculation in problems 4 and 5, find the distance traveled within that 4 s period. A truck decelerates at a rate of 2 m/s2. If it starts with a velocity of 15 m/s, how long will it take to stop? An object with a starting velocity of 15 m/s accelerates at 3 m/s2. How far does the object travel within 10 seconds?
Answer:
1. 75 kilometers per hour
2. 5.4 kilometers
3. I expect the storm to arrive 2.3 hours.
4. Acceleration = 8.75 [tex]m/s^{2}[/tex]
5. 200 meters
6. The truck will take 7.5 seconds to stop
7. The object travels 150 meters within 10 seconds
Step-by-step explanation:
1. Average speed = [tex]\frac{distance}{time}[/tex]
[tex]= \frac{375}{5}[/tex]
= 75 kilometers per hour
2. Distance = speed × time
Time taken = 15 minutes
= 15 × 60
= 900 seconds
Distance = 6 × 900
= 5400 meters
= 5400/1000
= 5.4 kilometers
So, the boat traveled 5.4 kilometers.
3. Time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{80}{35}[/tex]
= 2.286
So, I expect the storm to arrive in 2.3 hours.
4. Acceleration = Rate of change of velocity
= [tex]\frac{50-15}{4}[/tex]
= [tex]\frac{35}{4}[/tex]
= 8.75 [tex]m/s^{2}[/tex]
5. Distance = speed × time
= 50 × 4
= 200 meters
6. Time = [tex]\frac{velocity}{acceleration}[/tex]
= [tex]\frac{15}{2}[/tex]
= 7.5 seconds
The truck will take 7.5 seconds to stop
7. Distance = Velocity × Time
= 15 × 10
= 150 meters
Hence, the object travels 150 meters within 10 seconds.

Jackson is buying a good chain that had an original price of $795 but is advertised as 65% off. Sales tax of 8.50% is applied tot he discounted price. How much will Jackson pay for the chain ?
To find out how much Jackson will pay for the gold chain, you calculate the discount price by subtracting 65% of the original price from the original price, then apply an 8.50% sales tax to the discounted price, and add it to the discounted price to get the total cost. Jackson will pay a total of $301.90 for the gold chain.
Jackson is planning to buy a gold chain with an original price of $795 which is advertised at a 65% discount. The formula to calculate the discount price is:
Discount Price = Original Price - (Discount percentage x Original Price)First, we convert 65% to a decimal, which is 0.65:
Discount Price = $795 - ($795 x 0.65)Then, calculate the discount:
Discount Price = $795 - ($516.75)So after the discount, the price becomes:
Discount Price = $278.25On this discounted price, a sales tax of 8.50% is applied. Converting that to decimal will be 0.085 and now we multiply it with the discounted price:
Sales Tax Amount = 0.085 x $278.25Now, find the amount of sales tax:
Sales Tax Amount = $23.65125Round the sales tax to the nearest cent:
Sales Tax Amount = $23.65Finally, add the original discount price and the sales tax:
Total Price = Discount Price + Sales Tax AmountTotal Price:
Total Price = $278.25 + $23.65 = $301.90Jackson will pay $301.90 in total for the gold chain after applying the discount and sales tax.
