By rounding off, we can determine that Mike thought the difference would be 72 whereas it is actually 72.74.

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number.

For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

The crucial figures are preserved when numbers are rounded off.

Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up.

So, Mike calculated 79 as 79.44 and 7 as 6.7, so he calculated the difference as follows:

79 - 7 = 72

Actual figures that differ are:

79.44 - 6.7 = 72.74

Therefore, by rounding off, we can determine that Mike thought the difference would be 72 whereas it is actually 72.74.

Answer:

y = -x +8

Step-by-step explanation:

The line crosses the x axis at 8. So we know when y = 0 then x = 8

The line cross the y axis at 8. so we know when x = 0 then y = 8

the equation of a line we know to take the form y = mx + c

When x = 0 and y = 8, and y = mx+ c then then c =8

when y = 0 x = 8. y = mx + c, 0 = m(8) +8. for this to be true m must be equal to -1

so the equation of the line, the inequality is y = -x +8

If the Car drive 15, 000 miles then gas used is 315 galloons.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In 16.8 galloons of gas the Car can travel 400 miles.

So, if they dive about 15,000 miles then the gas in galloons used

= 16.8/400 x 15000

= 2.1 x 150

= 315 galloons.

Jayden is folding a paper strip of 66 cm into a 6 sided honeycomb. So the length of each side will be 11cm.

Jayden has a paper strip of length 66 cm. He had to make a honeycomb with it. It will have six equal sides. To calculate the length we have to formulate the equation.

Total length = number of sides × length of one side

 66 = 6 × x

Dividing by 6 on both sides,

66÷6 = 6x ÷ 6

11 = x

The statement "F(x) > 0 over the interval (-∞, -4)" is true.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. The addition, subtraction, multiplication, and division of functions are discussed in function algebra. We just perform the same operation for individual functions at the same input for every arithmetic operation of two functions at an input.

Here,

For any value of x less than -4, substituting it into the expression f(x) = x² + 4 will result in a positive value since x² is always positive. For example, if x = -5, then f(x) = (-5)² + 4 = 9 + 4 = 13, which is positive.

So, for all values of x that are less than -4, the function f(x) will have a positive value, making the statement "F(x) > 0 over the interval (-∞, -4)" true.

F(x) = 4x & g(x) = 3x are the two functions which the (f o g)(x) was equal to "12x".

Legislation, a regulation, or a declaration that demonstrates the relationships between the independent and relationship between the factors (the dependent variable). Functions may be found everywhere in mathematics, and they are essential for building physical connections in the sciences.

For the following two functions, (f o g)(x) was identical to "12x":

f(x) = 4x and g(x) = 3x.

Proof :

g(x) = 3x

(f o g)(x) = f(x = 3x) = 4(3x) = 12x

(f o g)(x) = 12x

The inequality used to determine v, the minimum number of visits Taylor needs to earn her first free movie ticket is 75 + 6.5v ≥ 100.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given,

Points for signing up = 75 points

Points for each visit to the movie theater = 6.5 points

Let v be the minimum number of visits Taylor needs to earn her first free movie ticket.

Points earned for v visits = 6.5v

She needs at least 100 points for a free movie ticket.

75 + 6.5v will be the points she earn for a free movie ticket.

Answer:

[tex]\displaystyle{52\sqrt{\dfrac{39}{\pi}} \ \: \text{cm}^3}[/tex]

Step-by-step explanation:

The surface area of the sphere has formula of [tex]\displaystyle{4\pi r^2}[/tex] where r is radius. Therefore, set the equation:

[tex]\displaystyle{4\pi r^2=156}[/tex]

Divide both sides by 156:

[tex]\displaystyle{\dfrac{4\pir^2}{4}=\dfrac{156}{4}}\\\\\displaystyle{\pi r^2=39}[/tex]

Then divide both sides by [tex]\displaystyle{\pi}[/tex]:

[tex]\displaystyle{\dfrac{\pi r^2}{\pi} = \dfrac{39}{\pi}}\\\\\displaystyle{r^2=\dfrac{39}{\pi}[/tex]

Square root both sides:

[tex]\displaystyle{\sqrt{r^2}=\sqrt{\dfrac{39}{\pi}}}\\\\\displaystyle{r=\pm\sqrt{\dfrac{39}{\pi}}}[/tex]

However, radius can only be positive. Therefore:

[tex]\displaystyle{r=\sqrt{\dfrac{39}{\pi}}}[/tex]

To find the volume, we have to know that the sphere's volume is:

[tex]\displaystyle{\dfrac{4}{3}\pi r^3}[/tex]

Thus, substitute the value of r in:

[tex]\displaystyle{\text{V} = \dfrac{4}{3}\pi \cdot \left(\sqrt{\dfrac{39}{\pi}}\right)^3}\\\\\displaystyle{\text{V} = \dfrac{4}{3}\pi \cdot \dfrac{39}{\pi}\sqrt{\dfrac{39}{\pi}}}\\\\\displaystyle{\text{V} = 52 \sqrt { \dfrac{39}{\pi}}}[/tex]

Therefore, the volume of sphere is:

[tex]\displaystyle{52\sqrt{\dfrac{39}{\pi}} \ \: \text{cm}^3}[/tex]

Between the time interval 0 to 1 hour, the greatest average rate of change is 700. Therefore, the option (1) is the correct answer.

The slope or rate of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).

Here,

1) 0 to 1 hour

Consider the coordinate points (0, 0) and (1, 700)

Now, rate = (700-0)/(1-0)

= 700

2) 1 hour to 1.5 hours

Consider the coordinate points (1, 700) and (1.5, 900)

Now, rate = (900-700)/(1.5-1)

= 200/0.5

= 400

3) 2.5 hours to 5 hours

Consider the coordinate points (2.5, 1000) and (5, 1640)

Now, rate = (1640-1000)/(5-2.5)

= 640/2.5

= 256

4) 5 hours to 8 hours

Consider the coordinate points (5, 1640) and (8, 1800)

Now, rate = (1800-1640)/(8-5)
