Paul's family drove 377 mi to the beach averaging 58 mi/h on the way there. On the return trip home, they averaged 65 mi/h .
What was the total time Paul's family spent driving to and from the beach?
Answers
Total time driving to and from beach: 12.3 hours; averaging 58 mph there, 65 mph returning home.
To find the total time Paul's family spent driving to and from the beach, we can calculate the time for each leg of the trip and then add them together.
1. Time taken for the trip to the beach:
[tex]\[ \text{Time}_1 = \frac{\text{Distance}_1}{\text{Speed}_1} \][/tex]
2. Time taken for the return trip:
[tex]\[ \text{Time}_2 = \frac{\text{Distance}_2}{\text{Speed}_2} \][/tex]
Given:
[tex]- Distance to the beach, \( \text{Distance}_1 = 377 \) miles\\- Speed to the beach, \( \text{Speed}_1 = 58 \) mph\\- Speed returning home, \( \text{Speed}_2 = 65 \) mph[/tex]
Let's calculate:
[tex]1. \[ \text{Time}_1 = \frac{377}{58} \][/tex]
[tex]2. \[ \text{Time}_2 = \frac{377}{65} \][/tex]
Now, let's compute:
[tex]\[ \text{Time}_1 = \frac{377}{58} \approx 6.5 \text{ hours} \]\[ \text{Time}_2 = \frac{377}{65} \approx 5.8 \text{ hours} \][/tex]
Finally, to find the total time spent driving to and from the beach, we add these times:
[tex]\[ \text{Total time} = \text{Time}_1 + \text{Time}_2 \]\[ \text{Total time} \approx 6.5 + 5.8 \]\[ \text{Total time} \approx 12.3 \text{ hours} \][/tex]
So, Paul's family spent approximately 12.3 hours driving to and from the beach.
The outside temperature was 73°f at 1.p.m and decreases at a rate of 1.5°f each hour. What expression can be used to determine the temperature h(h is the variable) hours after 1.p.m?
Answers
The expression to represent the temperature 'h' hours after 1 p.m. given an initial temperature of 73°F and a decrease rate of 1.5°F per hour is 73 - 1.5h. This allows us to calculate the temperature at any given hour where 'h' is the number of hours after 1 p.m.
Explanation:The problem involves dealing with linear equations, specifically those representing changes over time. In this situation, the temperature starts at 73°F at beginning of the time, i.e., at 1 pm and then decreases at a steady rate of 1.5°F per hour.
So, the decrease in temperature can be represented by 1.5h, where h is the number of hours elapsed since 1 p.m. As the temperature starts at 73°f, we subtract this decrease from the initial temperature. Therefore, the expression to determine the temperature after h hours is 73 - 1.5h.
This equation tells us that for each hour after 1 p.m., we simply subtract 1.5 from 73 and this would give the temperature at that time. For example, at 2 p.m., h equals 1, and the equation 73 - 1.5(1) gives us 71.5°F.

what is the first thing you need to do to add 1/9 5/6
Answers
To add fractions 1/9 and 5/6, find the least common denominator, convert each fraction to have this denominator, then add the numerators while keeping the denominator the same. The resulting fraction is 17/18.
Explanation:The first thing you need to do to add fractions 1/9 and 5/6 is to find a common denominator. Since we can only add numerators with the same denominator, we must convert these fractions so that they have the same bottom number. The least common denominator (LCD) for 9 and 6 is 18.
So, we convert 1/9 by multiplying both its numerator and denominator by 2, to get 2/18. Similarly, we convert 5/6 by multiplying both its numerator and denominator by 3, to get 15/18. Now we can add the numerators:
2/18 + 15/18 = 17/18
Remember, we never add the denominators; they remain the same. After finding a common denominator and converting each fraction, we add the numerators together to get the final result.
Final answer:
To add 1/9 and 5/6, find a common denominator, convert each fraction to an equivalent fraction with this denominator, and then add the numerators. The least common multiple of 9 and 6 is 18, leading to 1/9 + 5/6 = 17/18 after conversion and addition.
Explanation:
The first thing you need to do to add the fractions 1/9 and 5/6 is to find a common denominator. A common denominator is necessary because you can only add fractions directly when they share the same denominator. To find a common denominator, you can often multiply the denominators together, but it's better to find the least common multiple (LCM) of the two denominators to simplify the process.
Once the common denominator is found, you convert each fraction to an equivalent fraction with this common denominator. Then, you add the numerators while keeping the denominator the same. The denominators are never added together. If the result is an improper fraction, you may have to simplify it or convert it to a mixed number.
Using our given fractions, the LCM of 9 and 6 is 18. Therefore, 1/9 can be converted to 2/18 and 5/6 to 15/18. Adding these gives 2/18 + 15/18 = 17/18.

Answers
So B
I just took the test and got it correct!
Answer: B) 5, −3, 1 over 2 are the zeros of f(x).
Step-by-step explanation:
Given function f(x)=[tex]2x^3-5x^2-28x+15[/tex]
If a is a zero of f(x) then f(a)=0
Let's check all the options
[tex]f(5)=2(5)^3-5(5)^2-28(5)+15\\=2(125)-5(25)-28(5)+15=250-125-140+15=0[/tex]
[tex]f(-3)=2(-3)^3-5(-3)^2-28(-3)+15\\=2(-27)-5(9)-28(-3)+15=-54-45+84+15=0[/tex]
[tex]f(\frac{-1}{2})=2\frac{-1}{2}()^3-5(\frac{-1}{2})^2-28(\frac{-1}{2})+15\\=2(\frac{-1}{8})-5(\frac{-1}{4})+14+15=\frac{-1}{4}-\frac{5}{4}+29=\frac{110}{4}=\frac{55}{2}\neq 0[/tex]
Therefore , 5 and -3 are zeroes of f(x).but -1/2 is not.
[tex]f(\frac{1}{2})=2\frac{1}{2}()^3-5(\frac{1}{2})^2-28(\frac{1}{2})+15\\=2(\frac{1}{8})-5(\frac{1}{4})-14+15=\frac{1}{4}-\frac{5}{4}-14+15=0[/tex]
⇒ 1/2 isthe third zero of f(x).
Here we got our three zeroes as 5,-3,1/2,rest other will not satisfy f(a)=0
Therefore B represents the zeroes of f(x).
A number x plus 10 is more than 2

Find the equation of a line that intersects with y=2x-1 on the y-axis and is parallel to y=-x.
Please explain.
Answers
The equation of the required line is: y=-x-1.
y=2x-1 is in slope intercept form. So the y-intercept = -1.
Given that the line intersects with y=2x-1 on the y-axis. It means the required line also has y-intercpt =b= -1.
Given that: The line is parallel to y=-x.
The slope of y=-x is -1. By comparing with y=mx+b.
Since the lines are parallel. So the required line will also have slope = m= -1.
So the equation of the required line is: y=mx+b or y = -1x + (-1) or y=-x-1.
