It Took Jake 28 Minutes To Run 5km Last Months. This Month He Ran 5km In 21 Minutes. By What Percentage

Answers

Answer 1

Answer:

25%

Step-by-step explanation:

28-21=7

7/28=×/100

7×100=700

700÷28=25

Answer 2

Answer:

7

Step-by-step explanation:

Okay so, 28-21 =07 right

7 as a percent is 700% and the limit is 100%

so 700%/100%= 7

Step-by-step explanation:

The graph below shows where the two functions y = f(x) and y = g(x) intersect. Solve the equation f(x) = g(x).

Answers

Answer: (-2, 2) and (4, 8)

There are two solutions because the two functions cross each other twice.

The solutions of the equation f(x) = g(x) are (4, 8) and (-2, 2).

We have a graphical representation of two functions f(x) and g(x) and where they intersect.

We have to solve the equation f(x) = g(x)

Two functions A(x) and B(x) are plotted on the graph such that these these two functions intersect each other at three different coordinates. The total number of solutions possible for - A(x) = B(x) is ?

The total number of solutions can be calculated by counting the points at which these curves intersect each other. Hence, the total number of possible solutions are 3.

In the question given - We have a straight line and a parabola -

Now, we just have to look at the points at which these two graphs intersect each other. It can be seen that - both the graphs cut each other at coordinates - (4, 8) and (-2, 2).

Hence, the solutions of the equation f(x) = g(x) are (4, 8) and (-2, 2).

Alternative Method -

The general equation of straight line is : y = mx + c and that of parabola is : y = [tex]\sqrt{4ax}[/tex]

The solution can be calculated by equating both of the above expressions and solving them.

mx + c = [tex]\sqrt{4ax}[/tex]

Step-by-step explanation:The equation for distance is speed = distance ÷ time.Rearrange the equation to make distance the subject:

        (multiply both sides by time)

        Distance = Speed × Time

Convert your numbers into suitable units:

        1 mile ÷ 15 = 0.06m/minute

Finally, substitute the numbers into the equation and solve:

        Distance = 0.06 × 65 = 4.3miles (rounded to the nearest decimal place)

Two students in the same Spanish class, Cindy and Ruben, plan to get together after school to make

Ruben hasn't started yet so he has none. Since Cindy makes 9 flashcards per minute and Ruben makes
10 flashcards, Ruben will soon have the same number of flashcards.
Which variables will you use and what do they represent?
Write your system of linear equations below.
Solve the system.
How much time will it take for Cindy and Ruben to have the same number of flashcards?
How many flashcards will each student have at that time?

Answers

Answer:

Equations:

[tex]y = 14 + 9 x[/tex] --- Cindy

[tex]y = 10 x[/tex] --- Ruben

Solution to equation:

Time they have the same amount: 14 minutes

Number of cards they have at that time: 140 flashcards

Step-by-step explanation:

Solving (a): Variables and what they represent

The variables to use are x and y

Where x represent the minutes and y represents the number of flashcards in x minutes

Solving (b): System of linear equation

Cindy:

[tex]Existing\ Flashcards = 14[/tex]

[tex]Additional = 9[/tex] per minute

Total number of flashcards (y) in x minutes is:

[tex]y = Existing\ Flashcards + Additional * x[/tex]

[tex]y = 14 + 9 * x[/tex]

[tex]y = 14 + 9 x[/tex]

Ruben:

[tex]Rate = 10[/tex] per minute

Total number of flashcards (y) in x minutes is:

[tex]y = Rate * x[/tex]

[tex]y = 10 * x[/tex]

[tex]y = 10 x[/tex]

Solution to Equations:

Time they have the same amount.

To do this, we [tex]equate[/tex] [tex]both[/tex] expressions

i.e.

[tex]10x = 14 + 9x[/tex]

Collect Like Terms

[tex]10x - 9x = 14[/tex]

[tex]x = 14[/tex]

Number of cards they have at that time.

Here, we simply substitute 14 for x in any of the equations.

[tex]y = 10 x[/tex]

[tex]y = 10 * 14[/tex]

[tex]y = 140[/tex]

or

[tex]y = 14 + 9 x[/tex]

[tex]y = 14 + 9 * 14[/tex]

[tex]y = 14 + 126[/tex]

[tex]y = 140[/tex]

Answers

Answer:

A. 1

Step-by-step explanation:

✔️To find f(g(1)), first find g(1).

From the mapping given for g(x), the corresponding value of x = 1, is 0.

That is,

g(1) = 0

✔️Next is to find f(g(1)) by replacing x with 0 in f(x) = 3√x + 1

Thus:

f(g(1)) = 3√0 + 1

f(g(1)) = 0 + 1

f(g(1)) = 1
