Step-by-step explanation:

The question is incomplete, as the map or the scale length of the plants are not given.

To solve this, I will assume that:

[tex]Scale\ Distance = x[/tex]

[tex]Scale\ Ratio = 1\ unit : 1\ km[/tex]

Required

The total length

To get the total length (actual length), multiply the scale ratio by the scale distance;

[tex]Actual = Scale\ Distance * Scale\ Ratio[/tex]

So, we have:

[tex]Actual = x * 1km[/tex]

[tex]Actual = x\ km[/tex]

Assume that:

[tex]x = 5[/tex]

The total length will be:

[tex]Actual = 5km[/tex]

Answer:

Answer = D

Step-by-step explanation:

If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

I hope this helps have a good day :)

The typical second-grade student is about 48 inches tall.

'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'

According to the given problem,

Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }

Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52

                                     = 480

Average of the given heights = [tex]\frac{480}{10}[/tex]

                                                 = 48

Hence, we can conclude,  The typical second-grade student is about 48 inches tall since the average of the given data is 48.

Answer:

third side is 2√33

Step-by-step explanation:

Hi there!

We need to find the third side (hypotenuse, or the side opposite to the right angle) of the triangle, and we're given the measures of the 2 other sides (legs, or the sides make up the right angle)

To find the hypotenuse, we can use Pythagorean theorem, which is given as:

a²+b²=c², where a and b are the legs, and c is the hypotenuse

as stated above, we know that the legs are 7 and √83

substitute them as a and b into the theorem

remember that (√x)²=(√x)(√x)=x

7²+(√83)²=c²

raise all numbers (multiply 7 by itself and multiply √83 by itself)

49+83=c²

add 49 and 83 together

132=c²

take the square root of both sides

√132=c

the question asks for simplest radical form, written as x√y, where x is the square root of a perfect square, and y is what's left after the prefect square is pulled out. For example, 2√3 is √12 (12 is 4*3, and 4 is a perfect square. Recall that √xy is equal to √x*√y. Taking the square root of 4 gives us 2, while taking the square root 3 gives us √3. Multiplying them together makes the number 2√3)

132 is divisible by 4 (the last two digits makes 32, which is divisible by 4). 132/4=33

so 132 is 4*33

pull out 4 from under the radical, take the square root of it, and leave √33 as is

the simplified radical form is 2√33

So the third side is 2√33

Hope this helps!

Answer:

Step-by-step explanation:

Answer:

(-1, 2/3).

Step-by-step explanation:

Taking the derivative of f, we get f' = x^2 - 1 = 0.  Thus, x = -1 and x = +1.

At the relative max, y = (1/3)(-1)^3 - (-1) = -1/3 + 1 = 2/3.

The relative maximum is at (-1, 2/3).

Answer:

80 meters

Step-by-step explanation:

Length of rectangular field = x

Width of rectangular field = 50

Meters of Fencing required = perimeter of rectangle = 260 m

Perimeter of a rectangle = 2(length + width)

260 = 2(x + 50)

260 = 2x + 100

260 - 100 = 2x

160 = 2x

x = 160 / 2

x = 80 meters

Answer:

Step-by-step explanation:

assuming that the triangles are similar,  which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.

' = feet

" = inches

h / 20' = 4'-2" / 3'-4"

just use inches for this,  it's easier

h / 240" = 50" / 40"

h = 240 ( 50 / 40 )

h = 300"

h = 25'

Answer:

12

Step-by-step explanation:

18*2=36, 60-36=24, 24/2=12

The width of the room if the length is 18m is 1.66m.

We have given that,

Perimeter=60 and length=18m

P=2(l+w)

Where the l is the length and

W is the width

Perimeter=60 and length=18m.

Use this value in the formula of perimeter

60=2(18×W)

Divide both sides by 2

30=18w

isolate the w

Therefore, divide both sides by 18.

30/18=w

W=1.66m

Therefore the width of the room if the length is 18m is 1.66m.

Answer:

The answer is C

Step-by-step explanation:

Answer:

1 centimet

Step-by-step explanation:

Answer:

A Centimeter!

Step-by-step explanation:

Heard of the Acronym

King Henry Died m Drinking Chocolate Milk

K = King = Kilometers

H = Henry = Hectometers

D = Died = Decameters

M = m = meters

D = Drinking = Decimeters

C = Chocolate = centimeters

The metric system is based on the power of ten.

There are 10 Decimeters in a meter

There are 100 Centimeters (your answer) in a meter

There are 1000 Millimeters in a meter

Similarly:

1 Decameter = 10 meters

1 Hectometer = 100 meters

1 Kilometer = 1000 meters

So you can use it for this:

1 Hectometer = (10x10x10x10)cm or 10,000 cm

In this problem I am starting at 10, and multiplying as many tens as I need to get to Hectometer ( refer acronym).

Centimeters to Decimeters = 10

Decimeters to Meters = 10

Meters to Decameters = 10

Decameters to Hectometers is 10

So we have 4 - 10s so we do 10x10x10x10 or 10,000 cm in a Hectometer

1 cm would equal 0.0001 Hectometer

or 1/10,000 of a cm
