A group of friends traveled at a constant rate. They traveled 2/5 of a mile in 1/4 of an hour.Which of the following statements are true about this unit rate? Select all that apply.A divide 2/5 by 1/4 to find the unit rate per hour B The average speed will be less than 1 mile per hour because the group travels less than a fourth of a mile in1/4 of an hour C The group traveled at an average speed of 1 3/5 miles per hour.D The average speed will be greater than 1 mile per hour because the group travels more than a fourth of a mile in1/4 of an hour .E The group traveled at an average speed of 2 1/4 of a miles per hour.

Answers

Answer 1

The distance traveled, d = 2/5 miles = 0.4 miles.

The time taken to travel 0.4miles is given as, t = 1/4 hr = 0.25 hr.

Thus, the average speed, s = distance traveled divided by time taken.

i.e.

[tex]\begin{gathered} \text{average speed = }\frac{distance\text{ traveled}}{\text{time taken}}\text{ = }\frac{0.4}{0.25}\text{ } \\ \text{average sp}eed\text{ = 1.6 miles/hr} \end{gathered}[/tex]

we can now go through the options and see the correct answers:

option A is correct because unit rate per hour is the same thing as average speed

option B is wrong because average speed is greater than 1mile/hr from our calculation above

option C is wrong because 13/5 gives us 2.6 miles/hr

option D is correct because the average speed is indeed greater than 1

option E is wrong because average speed is 1.6 miles/hr not 2 1/4 miles/hr

Thus, the answers are:

Option A and Option D

You went to an action figure shop to buy a figure of your favorite anime character. The purchase price was $20, and the selling price was $30. You gave the shop owner $100, but the owner didn't have any change. So he went to the neighboring shop, got change for $100, and gave you $70. Unfortunately, the neighboring shop owner found out that the 100-dollar bill given to him was fake, so he went to the action figure shop and got back his change of $100. Now the question is, how much did the owner of the action figure store lose in total?

Answers

The owner loses the figure and the $70 that gives back, so the total amount he loses is $90.

How much did the owner of the action figure store lose in total?

We know that the owner initially has a figure whose price is $20, and he sells it for $30.

Then, he sells it for a $100 bill, so he gives $70 back.

The problem is that the $100 bill was fake, so at this point the total amount that he loses is:

The value of the action figure (which is $20) plus the $70 that he gives back.

Adding these two we get:

$20 + $70 = $90

The level of ibuprofen in the patients bloodstream increased from 0 hours to 2 hours.

What is ibuprofen?

Ibuprofen is an example of an NSAID that is used to relieve pain, fever, and inflammation. This includes menstruation pain, migraines, and rheumatoid arthritis. Additionally, it can be applied to seal off a premature infant's patent ductus arteriosus. It can be given orally or intravenously. After an hour, it usually begins to function.

In the graph that is attached, the y-axis represents the concentration of ibuprofen in the patient's bloodstream, and the x-axis represents the number of hours since ibuprofen was last consumed.

As we can see from the graph, the curve increases from a time of 0 hours, which corresponds to 0 mg of ibuprofen, to a time of 2 hours, which corresponds to 400 mg of ibuprofen.

The curve starts to descend after that point. We will settle for the first assertion because increase is what we are interested in.

Thus, we may conclude that the increase in ibuprofen level occurred between 0 and 2 hours.

Answer this Graph based Question I will make you brailiest and provide you 50 points. And also explain the (vii) Question..​

Answers

Answer:

(i) -2, (ii) Attached, (iii) x = - 1, (iv) y=6 maximum, y= - 2 minimum, (v) x = 0.723, (vi) y = - 3, (vii) y = - 1

Step-by-step explanation:

Given

Function y = (x + 1)² - 3

(i) Find the value of y when x = - 2

y = (- 2 + 1)² - 3 = (-1)² - 3 = 1 - 3 = - 2

(ii) See the graph attached

(iii) The axis of symmetry is the vertical line passing through the vertex, which is x + 1 = 0 or x = - 1.

This is also reflected on the attached graph.

(iv) From the graph it is visible that in the given interval the function is decreasing, so the value at x = - 4 is the maximum and the value at x = - 2 is minimum:

y(-4) = (-4 + 1)² - 3 = 9 - 3 = 6 maximumy(-2) = (-2 + 1)² - 3 = 1 - 3 = - 2 minimum

These two points too are given on the same graph.

(v) There ate two x-intercepts, the one on the right is the larger one.

It is (0.732, 0), marked on the graph.

(vi) This function is the standard form of the given:

(x + 1)² - 3 = x² + 2x + 1 - 3 = x² + 2x - 2

With the positive leading coefficient of 1, it has a minimum value but no maximum. The minimum of this function is at its vertex, which is (- 1, 3) as per graph.

(vii) The function y = x² + 2x is the translation of the given function up by two units.

So its minimum value is 2 units greater:

Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $20 and same-day tickets cost $35. For one performance,
there were 60 tickets sold in all, and the total amount paid for them was $1500. How many tickets of each type were sold?
Number of advance tickets sold:
Number of same-day tickets sold:

Answers

The linear equation 20x + 35(60-x) = 1500 can be solved to find the number of tickets.

What is an equation?

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its related terms in various languages may have somewhat different definitions; for example, in French, an equation is described as including one or more elements, but in English, an equation is any well-formed formula that includes two expressions linked by an equals sign.

Let the number of advance tickets sold = x

And then, the number of same-day tickets sold = 60 - x

Then, the equation formed is

20x + 35(60-x) = 1500

=> 20x + 2100 - 35x = 1500

=> -15x = 1500 - 2100

=> x = -600/ -15 = 40

Hence, the number of advance tickets sold = 40

And the number of same-day tickets sold = 60 - 40 = 20

A car travels a distance of 100km for 1h38min45sec.a)Round off the time to the nearest 1/4 hour b)Use the rounded time to find the average speed for the journey​

Answers

Answer: 57.14 km/hr

Step-by-step explanation:  if an hour is divided into quarters it will be in increments of 15 minutes, since  one hour is 60 minutes.  60 minutes divided by 5 is 15 minutes.  

So 1 hour and 38 minutes is rounded off to 1 hour and 45 minutes.

this is 1 hour + 3/4 hour = 1 3/4 hour.  This is same as 1.75 hour

3/4 is .75

speed divided by the time will give the average speed.

100km/1.75hours  = 57.14 km/per hour

Answer:

(a)  1 hour 45 min

(b)  57.1 km/h (nearest tenth)

Step-by-step explanation:

Given information:

Distance = 100 kmTime = 1 h 38 min 45 sec

[tex]\large\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

Part (a)

[tex]\begin{aligned}\sf \dfrac{1}{4}\;hour &= \sf 1 \; hour \div 4 \\& = \sf 60 \;mins \div 4\\& = \sf 15 \; mins\end{aligned}[/tex]

Therefore, the nearest ¹/₄ hours either side of the given time is:

1 hour 30 min1 hour 45 min

1 h 38 min 45 sec is 8 min 45 sec more than 1 hour 30 min.

1 h 38 min 45 sec is 6 min 15 sec less than 1 hour 45 min.

Therefore, the nearest ¹/₄ hour to the given time is:  

1 hour 45 min.

Part (b)

1 hour 45 min = 1.75 min (in decimal form)

Substitute the given distance and the rounded time (in decimal form) into the formula and solve for speed:

[tex]\begin{aligned} \implies \sf Speed & =\sf \dfrac{Distance}{Time}\\\\& = \sf \dfrac{100}{1.75}\\\\& = \sf 57.1\;km/h\;(nearest\;tenth)\end{aligned}[/tex]

a. Interpret the terms and coefficient in the equation.

Answers

From the given parameters to determine the cost of the airline ticket, we can interpret that that the maximum amount that each ticket costs is $295 while the maximum amount of bags is 5 bags.

How to interpret Equation of a line in slope intercept form?

We are given the linear equation that represents the cost of an airline ticket after adding a number of checked bags as;

y = 145 + 30x

where;

y is the cost (in dollars) of an airline ticket after adding a number of checked bags

x is the number of checked bags

Thus, if there is a maximum of 5 bags that can be checked, then we have;

y = 145 + 30(5)

y = $295

This means that the maximum amount that each ticket costs is $295 while the maximum amount of bags is 5 bags.

(A.) Given the one-to-one function f(x)= 7x - 2, find it's inverse function.
Which is f ^ -1(x)= 1/7x - 2/7

(B.) The graphs of f and f^ -1 are symmetric with respect to the line defined by
y = _______

Answers

The inverse function of one-to-one function f(x)= 7x - 2 is [tex]f^{-1}=\frac{x}{7}+\frac{2}{7}[/tex].

The graphs of f and [tex]f^{-1}[/tex] are symmetric with respect to the line defined by y = x.

Given that:-

f(x)= 7x - 2

Let f(x) = y

Hence,

[tex]f^{-1}(y)=x[/tex]

Hence, we can write,

y = 7x - 2

y + 2 = 7x

x = y/7 + 2/7

[tex]f^{-1}(y) = y/7 + 2/7[/tex]

Replacing y by x, we get,

[tex]f^{-1}(x) = x/7 + 2/7[/tex]

Hence, the inverse function of f(x) is [tex]f^{-1}(x) = x/7 + 2/7[/tex].

The graph of inverse is always the mirror image of the function's graph in the line y = x. It is because they're basically 100% similar but in reverse just like you in a mirror.

The formula C=3.14d can be used to approximate the circumference of a circle given its diameter. Company A manufactures and sells a certain washer with an outside circumference of 6 centimeters. The company has decided that a washer whose actual circumference is in the interval 5.8

Answers

Solving the circumference function, we have that:

The corresponding interval for diameters of the washers is 1.85 ≤ d ≤ 1.97.

What is the interval of possible values for the diameter?

The circumference of a circle of diameter d is given by:

C = 3.14d.

As stated in the problem.

The interval of circumference values is:

5.8 ≤ C ≤ 6.2.

Hence the lowest possible value for the diameter is given by:

3.14d = 5.8

d = 5.8/3.14

d = 1.85.

The highest possible value for the diameter is given by:

3.14d = 6.2

d = 6.2/3.14

d = 1.97.

Then the compound inequality that completes the given sentence is:

1.85 ≤ d ≤ 1.97.

What is the missing information?

The interval for the circumference values is given by:

5.8 ≤ C ≤ 6.2.

We have to complete the following sentence with the compound inequality:
