how do find the length of a rectangle ​

Answer:

90.5

Step-by-step explanation:

T(57)=.18(57)+80.25

T(57)=10.26+80.25

T(57)=90.51   (round to the one descimal place)

your answer would be

T(57)=90.5

The temperature T(57) is 90.5 and it states that the temperature for 57 days from April 1 2015 is 90.5.

Given,

The function T ( x ) = .18 x + 80.25 gives an estimate of the daily high temperature during this period where x is the number of days after April 1, 2015.

We need to evaluate T ( 57 ) (rounded to one decimal place) and then state its physical interpretation.

A function has an input and an output.

Example:

f(x) = x + 5

x = 1

f(1) = 1 + 5 = 6

1 = input

6 = output

Find T(x) at t = 57.

We have,

T(x) = 0.18 x + 80.25

T(57) = 0.18 x 57 + 80.25

T(57) = 10.26 + 80.25

T(57) = 90.51

Rounding to one decimal place.

90.51 = 90.5

T(57) = 90.5

T(57) = 90.5 means that the temperature for 57 days from April 1 2015 is 90.5

Thus the temperature T(57) is 90.5 and it states that the temperature for 57 days from April 1 2015 is 90.5.

Answer:

Step-by-step explanation:

Using the formula for calculating the standard error of the mean to get the standard deviation. The standard error of the mean is expressed as;

SE = S/√n where;

S is the standard deviation

n is the sample size

Given SE = 25 months and n = 1, on substituting this parameters into the formula, we will have;

25 = S/√1

25 = S/1

cross multiply

S = 25*1

S = 25 months

Hence the standard deviation based on the sample is 25 months

Step-by-step explanation:

An easy way to do this is to draw a giant rectangle. when you do you simply want to stay a line going straight across in the middle. draw 3/4 ontop and 6/8 on the bottom. or another fraction that's close to it. then shade in 3/4 and the same with 6/8. if the shading is the same length, that's how you know it's equivalent

Answer:

GE = 11 cm.

Step-by-step explanation:

The figure provided is attached below.

The information given is:

CD = 11.5

DE = 5.3

BC = 8

AH = 11

Perimeter = 73.8

BC = FG = EF

HA = GH

AB = GE

The perimeter of any figure is the sum of all its sides.

The perimeter of the figure provided is:

Perimeter = AB + BC + CD + DE + EF + FG + GH + HA

Perimeter = AB + BC + CD + DE + BC + BC + HA + HA

         [tex]73.8=AB+8+11.5+5.3+8+8+11+11[/tex]

         [tex]73.8=AB+62.8[/tex]

         [tex]AB=11[/tex]

The value of side AB is 11 cm.

Then the value of GE is also 11 cm.

Step-by-step explanation:

To find the radius of the sphere we must convert the inches to centimeters

Using the conversation

1 inch = 2.54 cm

If 1 inch = 2.54 cm

4.17 inch = 2.54 × 4.17 = 10.59 cm

We can find the radius using the formula

[tex]radius = \frac{diameter}{2} [/tex]

From the question

diameter = 10.59 cm

So we have

[tex]radius = \frac{10.59}{2} [/tex]

Surface area of a sphere= 4πr²

where

r is the radius

Surface area = 4(5.30)²π

= 112.36π

= 352.989

We have the answer as

Volume of a sphere is given by

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

r = 5.30

The volume of the sphere is

[tex] \frac{4}{3} ( {5.30})^{3} \pi[/tex]

= 623.61451

We have the answer as

First, add 3x and  subtract 4 from both sides:

-x (+3x) + 4 (-4) = -3x (+3x) + 8 (-4)

-x + 3x = 8 - 4

Simplify. Combine like terms:

3x - x = 8 - 4

Answer:

The square root of a prime number is always an irrational number, then the product of the square root of a prime number and a nonzero rational number is equivalent to:

"the product of an irrational number and a rational number different than zero...."

We know that the product of an irrational number and a rational number (different than zero) is ALWAYS an irrational number.

Then "When is the product of the square root of a prime number and a nonzero rational number a rational number?"

Never, the product will always be irrational.

Answer:

A) 22812 hotdogs per run

B) 75 runs/yr

C) 4 days in a run

Step-by-step explanation:

We are given;

Production rate;p = 5750 per day

Steady Usage rate;u = 270 per day

Setup cost of hotdog;S = $67

Annual carrying cost (H) = 47 cents = $0.47 per hot dog

No. of Production days; d = 297 days

A) Let's first find the annual demand given by the formula;

Annual demand;D = pd

D = 5750 × 297

D = 1707750 hot dogs/yr

Now, formula for optimal run size is given by;

Q_o = √[(2DS/H) × (p/(p - u))]

Plugging in the relevant values gives;

Q_o = √[(2 × 1707750 × 67/0.47) × (5750/(5650 - 270))]

Q_o =√520375454.7971209

Q_o = 22812 hotdogs per run

B) formula for Number of runs per year is given as;

No. of Runs = D/Q₀

Thus;

no. of runs = 1707750/22812

no. of runs ≈ 75 runs/yr

C) Length of a run is given by the formula;

Length = Q₀/p

Length = 22812/5750

Length ≈ 4 days in a run

Answer:

14 months

Step-by-step explanation:

Given

Gator's = $105 monthly charges

Tidal Wave = $375 registration fee + $80 monthly charged

Required

Determine for how many months Gators is cheaper

Let the number of months be x;

Represent the given data, algebraically.

For Gators: 105x

For Tidal Wave: 375 + 80x

Represent the above as a n inequality

Since Gators has to be cheaper; we have

[tex]105x < 375 + 80x[/tex]

Collect Like Terms

[tex]105x - 80x < 375[/tex]

[tex]25x < 375[/tex]

Divide both sides by 25

[tex]x < 15[/tex]

This implies that Gator's will be cheaper for months less than 15

Hence, the number of months is 14

Answer:

The graph is continuous.

Step-by-step explanation:

A continuous graph is depicted with straight smooth lines and not plot points as in a scatter graph.  On the other hand, discrete graphs represent values at specific points along the number line. The most common discrete graphs are those that represent sequences and series. Since, these discrete graphs do not possess a smooth continuous line, they rather have plot points above consecutive integer values, unlike some continuous line graphs.

Answer:

Option B is correct - The distribution has a region between two data values where no data were observed.

Step-by-step explanation:

To answer this question, i would use a sample histogram to explain the gaps in a histogram.

For example, a histogram has been attached.

The histogram has been plot to show the average height of children of different ages in a particular year.

From the attached image, we can see that all the bars represent average height of different ages.

Now, if one of the bars was to be empty which in this case means that the value there is zero and there is a gap. Since the bar is to represent average height of a particular age, it means that there was no data collected for that age as height cannot be zero!

This same reason applies generally to gaps in histogram which means that no data was collected for that particular bar region.

Thus, Option B is correct - The distribution has a region between two data values where no data were observed.

Answer:

  y = 3x -7

Step-by-step explanation:

The 2-point form of the equation of a line is useful for this.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (-1 -(-4))/(2 -1)(x -1) -4

  y = 3(x -1) -4

  y = 3x -7

Half of 30 is 15. You can obtain this by dividing it by 2 or multiplying it by 1/2.

Answer:

a. (0,0), (2,0), (4,0)

b. (0,0)

Step-by-step explanation:

To find the x-intercept points, you set the equation equal to 0.

0=x³-6x²+8x                                [factor out an x]

0=x(x²-6x+8)                                [factor (x²-6x+8)]

0=x(x-2)(x-4)                               [set each factor equal to 0]

x=0

x-2=0                                           [add both sides by 2]

x=2

x-4=0                                            [add both sides by 4]

x=4

Now, we know our x-intercept points: (0,0), (2,0), (4,0).

To find the y-intercept points, we know that it is located on the y-axis, meaning x=0. We plug in 0 for x, and we will know our y-intercept point.

y=(0)³-6(0)²+8(0)                         [multiply]

y=0

The y-intercept point is (0,0).
