Answer:

13.65 ≤ x < 13.75

Step-by-step explanation:

Let x represent the time in seconds. Since the time is 13.7 seconds when rounded to 1 decimal place, hence for this to be possible the minimum value of x is given as x ≥ 13.65 because 13.65 rounded to 1 decimal place is 13.7 seconds. Also, the maximum value of x is given as 13.75 because 13.75 rounded to 1 decimal place is 13.8 seconds.

Therefore the inequality to represent x is:

13.65 ≤ x < 13.75

Answer:

17.6 kilometers are equal to 11 miles.

Step-by-step explanation:

Given that:

8 kilometers = 5 miles

Unit rate in terms of kilometer.

1 kilometer = 5/8 miles

Now,

We have to convert 17.6 kilometers in miles

17.6 kilometers = [tex]\frac{5}{8}*17.6[/tex]

17.6 kilometers = [tex]\frac{5}{8}*\frac{176}{10}[/tex]

17.6 kilometers = 11 miles

Hence,

17.6 kilometers are equal to 11 miles.

Answer:

12.55

Step-by-step explanation:

The product of 3.06 and 4.1 rounded to the nearest hundredth is 12.55.

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

The given decimal numbers are 3.06 and 4.1.

Now, product =3.06×4.1

= 12.546

To the nearest hundredth is 12.55

Therefore, the product of 3.06 and 4.1 rounded to the nearest hundredth is 12.55.

Step-by-step explanation:

6x²-x-12

Answer:

Step-by-step explanation:

Equation of a line passing through (h, k) in point slope form is given by,

y - k = m(x - h)

From the graph attached,

Slope of the line passing through (6, 12) and (3, 21),

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{21-12}{3-6}[/tex]

   = -3

Therefore, point - slope form of the line passing through (3, 21) will be,

y - 21 = -3(x - 3)

Now convert this equation in slope intercept form,

y = -3x + 9 + 21

y = -3x + 31

(b). For x = 1 Or day 1

  y = -3(1) + 31

  y = 28 minutes

  Therefore, Phillip took 28 minutes initially to deliver his packages.

Slope of the line states the decrease in the delivery time per day that is 3 minutes per day.

Answer:

[tex]f(x) = 5x - 7 \\ change = f(7) - f( - 3) \\ = ((5)(7) - 7) - ((5)( - 3) - 7) \\ = (35 - 7) - ( - 15 - 7) \\ = (28) - ( - 22) \\ = 50 \\ average \: change = \frac{change}{2} \\ = \frac{50}{2} \\ = 25[/tex]

The rate of change of function f(x) = 5x - 7 from x = -3 to x = 7 will be equal to 5.

A function f(x) = 5x - 7 is given which changes from x = -3 to x = 7.

We have to find out the average rate of change for the given function.

What is the average rate of change of function from [tex]x_{1}[/tex] to [tex]x_{2}[/tex] ?

The average rate of change of function from [tex]x_{1}[/tex] to [tex]x_{2}[/tex] can be given by a formula which is [tex]\frac{f(x_{1})-f(x_{2})}{x_{1} - x_{2}}[/tex].

As per the question ;

The function is f(x) = 5x - 7

So,

At x = -3

f(x) = 5 × -3 - 7

f(x) = -15 - 7

f(x) = -22

At x = 7

f(x) = 5 × 7 - 7

f(x) = 35 - 7

f(x) = 28

Let's use the formula to find average rate of change of function ;

i.e.,

=  [tex]\frac{f(x_{1})-f(x_{2})}{x_{1} - x_{2}}[/tex]

= [tex]\frac{(28)-(-22)}{7-(-3)}[/tex]

= [tex]\frac{28+22}{7+3}[/tex]

= [tex]\frac{50}{10}[/tex]

= 5

Thus , the rate of change of function f(x) = 5x - 7 from x = -3 to x = 7 will be equal to 5.

Consider the complete question is "A store has two different sizes of ice cream on sale this week. The smaller container costs $3.87 for 48 ounces. The larger container costs $6.42 for 128 ounces. which ice cream costs less per ounce?"

Given:

The smaller container costs $3.87 for 48 ounces.

The larger container costs $6.42 for 128 ounces.

To find:

Which ice cream costs less per ounce?

Solution:

We know that

[tex]\text{Cost per ounce}=\dfrac{\text{Total cost}}{\text{Number of ounces}}[/tex]

Using this formula, we get

Per ounce cost of small container [tex]=\dfrac{3.87}{48}[/tex]

                                                         [tex]=0.080625[/tex]

                                                         [tex]\approx 0.08[/tex]

Per ounce cost of larger container [tex]=\dfrac{6.42}{128}[/tex]

                                                         [tex]=0.05015625[/tex]

                                                         [tex]\approx 0.05[/tex]

Since, 0.08 > 0.05 therefore, the per ounce cost of larger container is less.

Answer:

[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Step-by-step explanation:

In order to solve this question we need to understand the following.

[tex]\sqrt{x}[/tex] = [tex]x^{\frac{1}{2} }[/tex]

[tex]\sqrt[3]{x} = x^{\frac{1}{3} }[/tex]

[tex]\sqrt[4]{x}= x^{\frac{1}{4} }[/tex]

(Notice that the numerator of the fraction is the power of the x that is being squared)

If you need proof here it is.....

[tex]\sqrt{x} = x^{\frac{1}{2} }[/tex]

[tex](\sqrt{x} )^{2}[/tex] = [tex](x^{\frac{1}{2} } )^{2}[/tex]

x = x

Now that we got that out of the way we can rewrite [tex]\sqrt[7]{x^{3} }[/tex] as........

[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Answer:

The food will last for 25 days with 72 boys

Step-by-step explanation:

Proportions can be used to find the number of days the food will last for 72 boys.

60 boys in a hostel have food for 30 days.

Let x be the number of days for which the food will last

The proportion or product of both scenarios has to be same as the number of days and number of boys are proportional

Which means

[tex]60*30 = 72 * x\\x = \frac{60*30}{72}\\x = 25[/tex]

Hence,

The food will last for 25 days with 72 boys
