Answer:

d = 510 km

Step-by-step explanation:

She travelled the final 4 hours at a constant speed of 60 km/h.

distance = speed × time

distance = 60 km/h × 4 hours

distance = 240 km for the last 4 hours

She already had travelled 270 km in the first 3 hours.

d = total distance = 270 km + 240 km = 510 km

Answer: d = 510 km

3 chicken wings he buys after spending  $3.00

When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however, other symbols like the "*" sign are also occasionally used.

Tyshawn spent $23.00 on 23 chicken wings.

Therefore in $1 the chicken wings that can be brought will be
= 23 /23

= 1

As he spent $3.00 on the chicken wings then the quantity that he has brought will be

= $3 * 1

= 3

The number of chicken wings that were brought was 3.

The equations that will represent the reflected function are:

(c)  [tex]f(x)=5(\frac{1}{5})^{-x}[/tex] and;

(d) [tex]f(x)=5(5)^{x}[/tex]

If two functions share the same domain and codomain and have values that are consistent across all domain elements, they are said to be equivalent.

Consider the function,

[tex]f(x)=5(\frac{1}{5})^{x}[/tex]

Now,

Positive x-values and negative x-values are switched by a reflection over the y-axis, which also swaps the values of x and x.

So,

[tex]f(-x)=f(x)[/tex]

The reflection of the function f(x) across the y axis will be:

[tex]f(x)=5(\frac{1}{5})^{-x}[/tex]

Therefore, the equivalent function will be:

[tex]f(x)=5(\frac{1}{5})^{(-1)(x)}[/tex]

[tex]f(x)=5 \times ((\frac{1}{5})^{-1})^{x} \\f(x)=5(5)^{x}[/tex]

The number of students in each bus are 54 students .

Given that, 331 students went on a field trip. Six buses were filled and 7 students traveled in cars.

Now you may get that only 7 students out of 331 are travelled in cars whereas others travelled by bus.

number of total students travelled by bus are 331-7 = 324 students

Therefore 324 students travelled in 6 buses.

Number of students travelled in each bus = 324/6 = 54 students.

Therefore number of students travelled in each bus is 54 students .

verification:

number of buses = 6

number of students in each bus = 54

Therefore total number of students in 6 buses = 6*54 = 324 students.

The equation formed using the given data is 195 = x + 12 and your final score is 183 points.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say your final score is x

Given that,

Your final score x is 12 points less than your friend's final score.

So,

x = friend final score - 12

Now,

Friend final score = 195

So,

x = 195 - 12

x + 12 = 195

195 = x + 12

Now,

x = 195 - 12 = 183

Hence "The equation formed using the given data is 195 = x + 12 and your final score is 183 points".

The decay rate of a certain new cell phone is 0.333

For given question,

The average lifetime of a certain new cell phone is three years.

The manufacturer will replace any cell phone failing within two years of the date of purchase.

Also, the lifetime of these cell phones is known to follow an exponential distribution.

We need to find the decay rate.

We know that an exponential decay is the process of reducing an amount by a consistent percentage rate over a period of time.

since the average lifetime of a certain new cell phone is three years, the decay rate would be 1/3 = 0.333

By solving a system of equations, we can see that the chemist needs to use 375 mL of the 2% acid, and the other 225% of the 10% acid.

Let's define the variables that we will need to write our system of equations:

We know that the chemist wants to make 600mL of a 5% acid solution, so we can write the system of equations:

x + y = 600

x*0.02 + y*0.10 = 600*0.05

If we isolate y on the first equation, then we get:

y = 600 - x

Now we can replace that on the other equation so we get:

x*0.02 + (600 - x)*0.10 = 30

With this, we can get the value of x.

x*0.02 + 60 - x*0.10 = 30

-x*0.08 = 30 - 60 = -30

x = 30/0.08 = 375

So the chemist needs to use 375 mL of the 2% acid, and the other 225% of the 10% acid.

2) The solution of 4x² - 9 = 0 this quadratic equation is 3/2 and -3/2 through using factoring method.

4) The solution of both quadratic equations will give same results.

Explanation:

1) Sheryl says that the solutions of the quadratic equations w² = 49 and

w² +49 = 0 are the same. Do you agree with Sheryl? Justify your answer.

Solution:-

 According to Sheryl says that the solutions w² = 49 and w² +49 = 0 are the same.

Let's find the solution of given quadratic equations

        w = √49      ( ∵√49 = 7 )

         w = ±7

    So the solution of this quadratic equation 7 and -7

        w² = -49

        w  = √(-49)      ( ∵√49 = 7 )

         w = ±7 √-1       ( ∵√-1 = i )

   So the solution of this quadratic equation 7i and -7i

Now, let's solve that quadratic equation through factoring method.

      (2x)² - (3)² = 0                {∵ a²-b²= (a-b)(a+b)

   (2x-3)(2x+3) = 0

    If       (2x-3) = 0  

               2x-3 = 0      

                   2x = 3

                      x = 3/2

   And if  (2x+3) = 0

a. 4x² - 20x = 11

b. x² + 7x + 12 = 0.

Solution:-

a. 4x² - 20x = 11

For solve this quadratic equation, we can use completing the square method, because this equation is very hard to get it's factors.

So,

    4x² - 20x = 11

[tex]x^2-5x+(\frac{5}{2})^2 = \frac{11}{4} +(\frac{5}{2})^2\\x^2-2\times \frac{5}{2} \times x+(\frac{5}{2})^2 = \frac{11}{4} +\frac{25}{4}\\(x-\frac{5}{2})^2 = \frac{11+25}{4}\\(x-\frac{5}{2})^2 = \frac{36}{4}\\(x-\frac{5}{2})^2 = 9\\(x-\frac{5}{2})^2 = (3)^2\\(x-\frac{5}{2}) = \pm (3)\\\\[/tex]

 For taking + sign,

x - [tex]\frac{5}{2}[/tex] = 3

    x = 3 + [tex]\frac{5}{2}[/tex]

    x = [tex]\frac{6+5}{2}[/tex]

     x = [tex]\frac{11}{2}[/tex]

  For taking - sign,

x - [tex]\frac{5}{2}[/tex] = -3

    x =  [tex]\frac{5}{2}[/tex] - 3

    x = [tex]\frac{5-6}{2}[/tex]

     x = [tex]\frac{-1}{2}[/tex]

b. x² + 7x + 12 = 0.

For solve this quadratic equation, we can use factoring method, because that is very easy to get it's factors.

So,

            x² + 7x + 12 = 0

      x² + 4x +3x + 12 = 0

          x(x+4) +3(x+4) = 0

                 (x+4)(x+3) = 0

                If       (x+4) = 0  

                           x+4 = 0      

                               x = -4

             And if  (x+3) = 0

                           x+3 = 0      

                               x = -3

For 1st quadratic equation the value of a,b and c is -2, 8, and 3, respectively.

So, the quadratic equation is

For 2nd quadratic equation the value of a,b and c is 2, -8, and -3, respectively.

So, the quadratic equation is

Now, we have to find the solution of both equations are same or not.

So, the solution of 1st quadratic equation

       -2x²+8x+3 = 0

           2x-8x-3 = 0            (multiplying - with both sides)

Now, this equation convert in the form of 2nd quadratic equation. So we can say that the solution of both quadratic equations will give same results.
