Answer: Option C.

Step-by-step explanation:

The data is:

Destin walked 2km

Jane walked 4000ft.

Let's write both of those in the same units.

The data given is:

1ft = 0.0003048km.

and 4000ft is 4000 times that:

4000ft = 4000*1ft = 4000*0.0003048km = 1.22km

Then if we add those, we get:

Total distance = 2km + 1.22km = 3.22km

So we can already discard option D.

Now, we know that:

1km = 0.6214 miles.

then 3.22 km is 3.22 times that amount:

3.22km = 3.22*1km = 3.22*(0.6214 mi) = 2 miles

The correct option is C.

Answer:

(a) Equation: [tex]T_n = 11.25 - 1.25n[/tex]

(b) 7.5 gallons

Step-by-step explanation:

Given

Current Gas = 10 gallon

Every Hour = -1.25 gallon

Solving for (a): An equation for the scenario

This question represents an Arithmetic Progression and will be solved using the following formula:

[tex]T_n = a + (n - 1)d[/tex]

Where

[tex]a = 10[/tex]

[tex]d = -1.25[/tex]

Substitute these values in the formula

[tex]T_n = 10 + (n - 1) * -1.25[/tex]

[tex]T_n = 10 -1.25n +1.25[/tex]

Collect Like Terms

[tex]T_n = 10 + 1.25 - 1.25n[/tex]

[tex]T_n = 11.25 - 1.25n[/tex]

Solving for (b): In this case, n - 3

Substitute 3 for n in [tex]T_n = 11.25 - 1.25n[/tex]

[tex]T_3 = 11.25 - 1.25 * 3[/tex]

[tex]T_3 = 11.25 - 3.75[/tex]

[tex]T_3 = 7.5[/tex]

7.5 gallon of gas left

Answer:

So if 25% of the people go to work by bicycle then that means that 75% of people go to work by other means of transportation.

Therefore the odds against selecting someone who commutes by bicycle are 75% or 75/100 or 0.75.

Step-by-step explanation:

The odds against selecting someone who commutes by bicycle are 75%

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that In a certain town, 25% of people commute to work by bicycle. If a person is selected randomly from the town.

25% of the people go to work by bicycle then which means that 75% of people go to work by other means of transportation.

Therefore the odds against selecting someone who commutes by bicycle are 75% or 75/100 or 0.75.

Answer: He needs 80 cups.

Step-by-step explanation:$12/$.15=80 cups

Steps to solve:

3x - 5y = 20

~Subtract 3x to both sides

-5y = 20 - 3x

~Divide everything by -5

y = -4 + 3/5x

Best of Luck!

The equivalent value of the expression is y = ( 3x - 20 ) / 5

Given data ,

Let the equation be represented as A

Now , the value of A is

3x - 5y = 20

On simplifying the equation , we get

3x - 5y = 20

So , the left hand side of the equation is equated to the right hand side by the value of 20

Adding 5y on both sides , we get

3x = 20 + 5y

Subtracting 20 on both sides , we get

5y = 3x - 20

Divide by 5 on both sides , we get

y = ( 3x - 20 ) / 5

Therefore , the value of y = ( 3x - 20 ) / 5

Hence , the expression is y = ( 3x - 20 ) / 5

Answer:

-6

Step-by-step explanation:

g(1) would be equal to g(1) = -(1) - 5 = -6

So, the answer would be -6.

The value of g(1) is -6.

Given,

g(x) = -x - 5

We need to find g(1).

A function is given by f(x).

The value of x is called the domain.

The output we get after putting the domain x in the function is called the range.

Example:

f(x) = x + 2

x = 1

f(1) = 1 + 2 = 3

domain = 1

range = 3

Find g(x) at x = 1.

g(x) = -x - 5

Put x = 1

g(1) = -1 - 5

     = -6

g(1) = -6 is our answer.

Thus the value of g(1) is -6.

Given that:

The tables values which represents Age and Admission Price is

   Age           Admission Price

under 5                free

18–64                   $40

65 and over          $35

To find:

Domain and range of the function.

Solution:

Domain is the set of input values.

Here, domain is age because age is an independent variable.

Age cannot be negative, so

[tex]Domain:\{Age\geq 0\}=[0,\infity)[/tex]

Therefore, the domain is all number greater than or equal to 0.

Range is the set of input values.

Here, range is Admission Price because Admission Price is a dependent variable.

Admission Prices are free (i.e., 0), $25, $40 and $35. So

[tex]Range:\{0,25,35,40\}[/tex]

Therefore, range is {0,25,35,40}.

The cost of 4th book is $22.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, Jenny bought 4 books in a bookstore. The prices of the first 3 books were $10, $15 and $25.

Let the cost of 4th book be $x.

Now, average = (10+15+25+x)/4

(50+x)/4 =18

50+x =72

x=$22

Therefore, the cost of 4th book is $22.
