First, we will start by converting 607,200 feet to miles

1 mile= 5280 foot

607, 200 feet can be changed to mile by dividing it by 5280

That is;

607,200 feet to mile = 607, 200 / 5280 = 115 miles

Hence; speed

= distance over t/

= 115 /1

=115 miles per hour

The quadratic equation with roots 4 and -2 and leading coefficient 4 is;

⇒ 4x² - 8x - 32

What is Quadratic equation?

A quadratic equation is an algebraic equation of the second degree of x.

Given that;

Roots of a quadratic equation = 4 and -2

Leading coefficient = 4

Now, The quadratic equation whose roots 4 and -2 with leading coefficient is calculated as;

⇒ 4 ( x - 4) (x + 2)

Solve as;

= 4 (x - 4) (x + 2)

= 4 (x² + 2x - 4x - 8)

= 4 (x² - 2x - 8)

= 4x² - 8x - 32

Thus, The quadratic equation with roots 4 and -2 and leading coefficient 4 is;

Dragon needs 2.16 seconds to eat 90 kilograms of human beings.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that,

If a dragon can eat an entire cow weighing 500 kilograms in 12 seconds,

500 kilograms = 12 seconds

By unitary method

1 kilogram = 12 / 500

1 kilogram = 0.024 second

For 90 kilograms

90 kilogram=90 × 0.024 second

90 kilogram = 2.16 second

Thus, a dragon needs 2.16 seconds to eat 90 kilograms of human beings.

Part a: Cost of downloading album B = 13.3 euros

Part b: Cost of downloading album B = 12.6 euros

Number of tracks in album A = 11 tracks

The total cost of downloading album A = 10.45 euro

Cost of each track on album A = Total cost of album/Number of tracks in the album

= 0.95 euro

Part a:

Number of tracks in album B = 14 tracks

Cost of album B = Number of tracks in album B * Cost of each track

= 0.95*14

= 13.3 euros

Part b:

The cost of 5 tracks on album B is 5p less therefore, the cost of 5 tracks will be 0.90*5 = 3.60 euros

Steps to find the equation of a line from two points:

Find the slope using the slope formula. ...

Use the slope and one of the points to solve for the y-intercept (b). ...

Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

Step-by-step explanation:

Answer:

[tex]y=-2x+30[/tex]

where y is the weight of the cat (in pounds) and x is the number of months.

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

The y-intercept is the y-value when x is zero, so the initial value.

If the cat initially weighs 30 pounds, the y-intercept is 30.

The slope is the rate of change.

If the cat lost 2 pounds per month, then the rate of change is -2.

Therefore, the equation the models the given word problem is:

Answer:

  3(n +5)

Step-by-step explanation:

You want the math expression that means "three times the sum of a number and five."

A sum is represented using a plus sign. "A number" is represented using a variable. "x" is a variable commonly used for an unknown value. "n" can also be used to represent "a number."

The sum of a number and 5 will be ...

  n + 5

We want an expression that is 3 times that sum, so we multiply it by 3:

  3(n +5) . . . . . . 3 times the sum of a number and 5

Additional comment

Note that the expression above is not the same as 3n+5, which would represent "the sum of 3 times a number and 5".

Step-by-step explanation:

Your slope and your x and y intercept.

x + 2y =7

Divide through by 2, we have:

x/2 + 2y/2 = 7/2

x/2 + y = 7/2

y = 7/2 - x/2

The location of the image of point S is the midpoint of the line segment RS. A representation of the geometric system and the rigid transformation is shown in the image attached below.

Herein we know the center of dilation and the location of point S, which must be dilated by a rigid transformation, that is, a transformation applied on the point such that its Euclidean distance is conserved. The operation is defined by the following equation:

RS' = k · RS

S'(x) - R(x) = k · S(x) - k · R(x)

Where k is the scale factor.

If we know that R(x) = 0, S(x) = 6 and k = 1 / 2, then the location of the point S' is:

Answer:

Equation = 1/4 x + 25 = 70

Solution = $180

Explanation:

Let the original amount she had before she went shopping be x

If she spent one-fourth on sloth, then the amount spent on cloth will be;

1/4 x

If she receives another $25 a week later totalling her money $70, then the equation that represents the situation will be;

1/4 x + 25 = 70

Find the solution

1/4 x + 25 = 70

1/4 x = 70 - 25

1/4 x = 45

x = 45 * 4

x = 180

Hence the amount she had before going for shoppind was $180

A Dot Plot is a graphical display of quantitative data consisting of dots plotted on a simple scale.  Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line.

If a value occurs more than once, then the dots are placed one above the other thus, that the height of the column of dots represents the frequency for that value.

Given data set:

Length = 4*longer leg

Shorter leg of the base= 1/2 longer leg

We know that Volume = 5832 = 1/2* length* longer leg* shorter leg

Let's call x to the longer leg, the variables are:

length= 4*longer leg= 4x --> x is the longer leg

Shorter leg= 1/2longer leg= 1/2x --> x is the longer leg

Substituting terms, the equation would be:

Multiplying like terms:

Simplifying:

Switching sides:

Isolating x:

Solving the cubic root:

So, x is the value of the longer leg.

Now, we need to find the length, we know that length=4*longer leg

So, the length of the carton is 4*18= 72

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative integers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. The set that the values created are contained in is known as the codomain, while the set that the operation really produced is known as the codomain of definition, active codomain, image, or range. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.

A scalar can be multiplied by a vector to create another vector (a process known as scalar multiplication), and two vectors can be combined to make a scalar quantity in an inner product operation. An operation may or may not have specific characteristics, such as being idempotent, associative, commutative, or anticommutative.

Mean=54.1 Median=55 Mode=1 Midrange=53 are the correct values of mean, median, mode and midrange.

(a) Mean= sum of data/ number of data

=(55+64+45+77+88+51+41+54+35+67+18)/11

=595/11

=54.09 or 54.1

(b) Median is the middle value, which in this case is 51.

(c)  Mode is the count of the number stating how many time it has been repeated in the data.

For instance in the given data :-

55 64 45 77 88 51 41 54 35 67 18

mode of 55 is 1, since it appears only one time.

No numbers in the given data repeats, i.e. all the values are unique. Thus the mode of the given data is 1.

(d) Mid-range is (highest value in the data + lowest value in the data)/2

in this case, the highest value is 88 and the lowest value is 18. Substituting these values in the formula:

(88+18)/2

=106/2

=53

What is mean median mode and midrange?

Mean is the sum of data divided by number of data, Median is the middle value of the data when arranged in ascending or descending order, Mode is the count of the number stating how many time it has been repeated in the data and Mid-range is highest value in the data plus lowest value in the data whole divided by 2.

Answer:

Step-by-step explanation:

(a)

the 2 angles are same- side interior angles and are supplementary.

(c)

since they are supplementary , they sum to 180° , that is

6x + 14 + 10x - 10 = 180

16x + 4 = 180 ( subtract 4 from both sides )

16x = 176 ( divide both sides by 16 )

x = 11

(d)

then

6x + 14 = 6(11) + 14 = 66 + 14 = 80

10x - 10 = 10(11) - 10 = 110 - 10 = 100

note 80 + 100 = 180 ( supplementary angles )
