You are trying to decide between two job offers. You find the best option is to take the highway to work. That route is
calculated for driving at an average speed of 65 miles per hour. You would like to keep your morning commute down to less than 30
minutes. What is the farthest distance you can travel to work within the allowable time?
Answer:
32.5 miles
Step-by-step explanation:
The average speed is 65 miles per hour.
You want to keep your commute within 30 minutes, which is HALF AN HOUR.
THus, if you can go 65 miles AN HOUR, in HALF AN HOUR, you can go max, HALF OF THAT!!
So, [tex]\frac{1}{2}*65=32.5[/tex]
Thus, you can go 32.5 miles, max
Answer:
The farthest distance would be 32.5 miles
Step-by-step explanation:
Given,
Speed = 65 miles per hour,
If t represents the time ( in hours ) taken in travelling,
Since, time has to commute down less than 30 minutes,
Also, 1 hour = 60 minutes,
[tex]\implies 1\text{ minute}=\frac{1}{60}\text{ hour}[/tex]
[tex]\implies 30\text{ minutes}=\frac{30}{60}=\frac{1}{2}\text{ hour}[/tex]
Thus,
[tex]t\leq \frac{1}{2}[/tex]
i.e. the highest time taken = 1/2 hours,
We know that,
Distance = speed × time,
∵ Distance ∝ time,
⇒ Distance will farthest for largest time taken,
Hence, the farthest distance = [tex]65\times \frac{1}{2}[/tex] = 32.5 km.

Find the inverse function for f(2)= square root of 2x - 6.
Answer:
y = ( x^2 / 2 ) + 3
Step-by-step explanation:
Swap x and y, then isolate y to find a function's inverse
x = sqrt ( 2y - 6 )
x^2 = 2y - 6
x^2 + 6 = 2y
( x^2 / 2 ) + 3 = y
y = ( x^2 / 2 ) + 3 is the final answer.

The two angles given, X and 2x are supplementary angles which when added together need to equal 180 degrees.
Set up an equation to solve for x:
x + 2x = 180
Simplify:
3x = 180
Divide both sides by 3:
x = 180/3
x = 60 degrees.

8. Travel Times Journal found that the average per person cost of a
ound that the average per person cost of a 10-day trip along the Pacific
Coast, per person, is $1,015. This includes transportation, food, lodging, and entertainment.
a. If the data is normally distributed with standard deviation $198, find
ard deviation $198, find the percent of
Vacationers who spent less than $1.200 per day. Round to the nearest hundredth of a
percent.
Answer:
82.38%
Step-by-step explanation:
Average cost = u = $ 1,015
Standard Deviation = [tex]\sigma[/tex] = $ 198
Its given that data is normally distributed. We have to find what percentage of vacationers spend less than $ 1200.
Since the data is normally distributed, we can use the concept of z score to answer this question.
We have to find:
Probability ( Spending < 1200)
In symbolic form, this can be represented as:
P(X < 1200)
The formula for the z score is:
[tex]z=\frac{x-u}{\sigma}[/tex]
Using the values in this formula, we get:
[tex]z=\frac{1200-1015}{198}=0.93[/tex]
Thus,
P(X < 1200) is equivalent to P(z < 0.93)
From the z table we can find the probability of z scores being less than 0.93 to be 0.8238
Thus,
P(z < 0.93) = 0.8238
Since,
P(X < 1200) = P(z < 0.93), we can conclude:
The percent of Vacationers who spent less than $1,200 is 0.8238 or 82.38%
Which of the following statements is true concerning ABC below?
A. B is the largest angle.
B. B is the smallest angle
C. A is the largest angle
D. A is the smallest angle
Answer:
D. A is the smallest angle
Step-by-step explanation:
Angle A's lines are closest together
Answer:
D. A is the smallest angle
Step-by-step explanation:
To answer this question properly, we need to remember that the sum of the three angles, in a triangle, must result in 180º. Besides, each leg of this triangle is in the opposite direction to the angle of its vertex.
Finally, with the help of a compass we can demonstrate it even better, but in short, the larger the leg the larger the angle. So, ∠A is the smallest angle since a measures 7 units, then comes ∠B for b measures 10 units and ∠C as the largest angle for c measures 12 units.

Answer:
Part A: The cube root of a positive number is a positive number.
Part B: x = 3
A. Howie is wrong because he implied that the answer could be negative. B. The correct answer is x = 3.
When Howie attempted to solve the equation [tex]\(x^3 = 27\)[/tex], he mistakenly concluded that x = -3 was a solution.
However, [tex]\((-3)^3\)[/tex] is equal to -27, not 27. Therefore, -3 is not a valid solution to the equation.
Howie's answer was incorrect because he mistakenly included x = -3 as a solution, which does not satisfy the equation [tex]\(x^3 = 27\).[/tex]
The revised answer should only include the correct solution x = 3. The equation [tex]\(x^3 = 27\)[/tex] has only one real solution, which is:
x = 3
What is a number that is 10 times greater than 41,532
Answer:
415320
Step-by-step explanation:
According to the Power of 10 rule, whenever you divide by 10 [⅒], you move the decimal mark to the left each time, and of course, whenever you multiply by 10, you move the decimal mark to the right each time. In this case, the decimal mark is just after the 2, so multiplying by 10 will add a zero to the number, making it 413520 [four hundred thirteen thousand, five hundred twenty].

The ratio of girls to boys in the school orchestra is 15 to 10. Which ratio is equivalent to 15 to 10?
The equivalent ratio of girls to boys in the school orchestra is 3 to 2 or 3:2.
Solving equivalent ratios
Equivalent ratios are similar ratios in mathematics, that has different terms but the same solution after being solved. The ratio of two numbers usually compares the size of two numbers together.
To find equivalent ratio of a given number. we need to either multiply or divide the original value.
Here, we are to find the equivalent ratio of girls to boys in the school orchestra is 15 to 10.
Girls to boys = 15: 10
i.e.
[tex]\dfrac{15}{10}[/tex]
In its lowest terms, we can divide both the numerator and the denominator by 5, by doing so we get an equivalent ratio.
[tex]= \dfrac{15 \div 5}{10 \div 5}[/tex]

The temperature in Tampa, Florida is 15 degrees warmer than twice the temperature in Chicago, Illinois. The temperature in Tampa is 75 degrees. Write an equation to determine the temperature in Chicago.
Answer:
75=15+2x
30 degrees in Chicago
Step-by-step explanation:
x will be Chicago's temperature.
75=15+2x
Because 75 is the total temperature in Tampa, and you get that total temperature by adding 15 and 2 times the temperature of Chicago.
Subtract 15 from both sides.
60=2x
Divide 2 from both sides.
30=x
So it's 30 degrees in Chicago.
Answer: [tex]75=2C+15[/tex]
Step-by-step explanation:
Given : The temperature in Tampa, Florida is 15 degrees warmer than twice the temperature in Chicago, Illinois.
Let the temperature in Chicago is denoted as 'C in degrees'.
Since , The temperature in Tampa is 75 degrees.
Then, we have the following equation
[tex]75=2C+15[/tex]
Hence, an equation to determine the temperature in Chicago will be [tex]75=2C+15[/tex]

Whats the halfway point from 32 to 16?
Without multiplying, tell whether the product 0.644 x 0.25 will be greater than 1 or less than 1? Explain how you know.
Answer:
Less than 1
Step-by-step explanation:
As 0.644 and 0.25 are less than 1, then
[tex]0.644=\frac{1}{p}[/tex]
[tex]0.25=\frac{1}{q}[/tex]
where p and q are greater than 1
then
[tex]0.644\times0.24=\frac{1}{p.q}[/tex]
But p.q is greater than 1, so 1/(p.q) is smaller than 1
Answer:
Less than 1
Step-by-step explanation:
Both the number are less than 1, i.e 0.64 and 0.25.
Hence, the result will always be less than 1 and will be in zeros.
If you write both numbers in fraction, the denominator will be greater than the numerator, hence the resulting fraction will be less than 1.
Hope this helps.
Good luck and thankyou.

the owner of a butcher shop keeps the shop's freezer at -5°C. It is acceptable for the temperature to differ from this value by 1.5°. Write and solve an absolute-value equation to find minimum and maximum acceptable temperatures
Answer:
[tex]|x+5|=1.5[/tex]
is the equation describing minimum and maximum acceptable temperatures.
The minimum temperature could be [tex]-6.5^{\circ}[/tex]
and the maximum temperature could be [tex]-3.5^{\circ}[/tex]
Step-by-step explanation:
The owner of a butcher shop keeps the shop's freezer at -5°C. It is acceptable for the temperature to differ from this value by 1.5°. So, the minimum temperature could be
[tex]-5^{\circ}-1.5^{\circ}=-6.5^{\circ}[/tex]
and the maximum temperature could be
[tex]-5^{\circ}+1.5^{\circ}=-3.5^{\circ}[/tex]
Let [tex]x^{\circ}[/tex] be acceptable temperature of freezer. The difference between the acceptable temperature and given temperature [tex]x-(-5)=x+5[/tex] cannot be more than 1.5° and less than 1.5°, so
[tex]|x+5|\le 1.5[/tex]
Then
[tex]|x+5|=1.5[/tex]
is the equation describing minimum and maximum acceptable temperatures.
Solve it:
[tex]x+5=1.5\text{ or }x+5=-1.5\\ \\x=1.5-5\text{ or }x=-1.5-5\\ \\x=-3.5\text{ or }x=-6.5[/tex]
A cube has edge length s units. Use an exponent to write an expression for its volume
Answer:
s[tex]s^{3}[/tex]
Step-by-step explanation:
A cube's volume is its length * width * height. Its length, width, and height are all equal to s.
A cube's edge length is another word for its side length, which is the same for every edge in the cube.
To write the equation for the volume with s substituted for length, width, and height, we get that volume = s[tex]s^{3}[/tex].

Step-by-step explanation:
Lets revise the order of operation
# Multiplication and Division which comes first from left to right
# Addition and Subtraction which comes first from left to right
Lets explain how to solve the problem
17 __ 2 __ 3 __ 8 = 3
We want to use + , - , × or ÷ symbols to make the statement true
Lets try to find the correct operations
∵ The answer is smaller than all the numbers in the statement
∴ There is subtraction
∵ 17 - 2 = 15
∵ 15 - 3 = 12
∵ 12 - 8 = 4 which is not the answer
Then lets multiply 17 , 2 and multiply 3 , 8 and subtract their results
∵ 17 × 2 = 34
∵ 3 × 8 = 24
∵ 34 - 24 = 10 which is not the answer
Then lets multiply 2 , 3 and then subtract the result from 17 and then
subtract 8 from the last result
∵ 2 × 3 = 6
∵ 17 - 6 = 11
∵ 11 - 8 = 3 which is the answer
∴ 17 - 2 × 3 - 8 = 3
∴ The symbols are - , × , -
