Answer:

The actual height is 150ft

Step-by-step explanation:

Given

[tex]Width : Height = 2cm : 5cm[/tex]

[tex]Actual\ width = 60ft[/tex]

Required

Determine the actual height

Substitute 60ft for width in: [tex]Width : Height = 2cm : 5cm[/tex]

[tex]60ft:Height =2cm:5cm[/tex]

Express as fraction

[tex]\frac{60ft}{Height} =\frac{2cm}{5cm}[/tex]

[tex]\frac{60ft}{Height} =\frac{2}{5}[/tex]

Make height the subject

[tex]Height = \frac{5}{2} * 60ft[/tex]

[tex]Height = 5 * 30ft[/tex]

[tex]Height = 150ft[/tex]

Answer:

Step-by-step explanation:

1 cm represents 30 ft

height of building = 5 cm × 30 ft/cm = 150 ft

Step-by-step explanation:

for perimeter you just add up all of the sides so :

(x+4) +( 2x)+(4x-2)+(3x-1) = 10x +1

Answer:

is there anything to add to that? or is that it

Answer:

4. 25 5. 80 6. 30

Step-by-step explanation:

All triangles add up to 180.

The triangle in #4 is right, so 90° + 65° = 155°

180° - 155° = 25°

x=25

#5.

50° + 50° = 100°

180° - 100° = 80°

x=80

In #4 the triangle is an equilateral, so all the angles will be equal. 2x + 2x + 2x = 180

6x = 180

x = 30

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

Two of the angle measures are given in each triangle so to find the third angle measurement we need to subtract the sum of two of the interior angles

4.

180 - (65 + 90) = x

180 - 155 = x

25 = x

5.

180 - (50+5) = x

180 - 100 = x

80 = x

For the 6th question all side lengths are equal so the angle measures also equal and 60 each

2x = 60

x = 30

Answer:

20

Step-by-step explanation:

The equation for area of a triangle is base times height divided by two.

Answer:

1) decay

2) growth

3) growth

Step-by-step explanation:

A generic exponential function can be written as:

f(x) = A*(r)^x

Where:

A is the initial amount of something.

r is the rate of growth.

x is the variable, usually, represents time.

if r > 1, we have an exponential growth.

if r < 1, we have an exponential decay.

1) f(x) = (3/4)^x

in this case we have:

A = 1

r = (3/4) = 0.75

Clearly, r < 1.

Then this is an exponential decay.

2) f(x) = (1/6)*4^x

In this case we have:

A = (1/6)

r = 4

Here we have r > 1.

Then this is an exponential growth.

3) f(x) = (1/4)*(5/2)^x

in this case we have:

A = 1/4

r = 5/2 = 2.5

here we have r > 1, then this is an exponential growth.

Answer:

-6x^5+x^5+8x^4

Step-by-step explanation:

Answer:

-5x^5 + 8x^4

Step-by-step explanation:

you combine like terms with the ones that are to the 5th power and then add 8x^4

Answer:

A

Step-by-step explanation:

So, first we have to eliminate answers, let us check A first. If we simplify this equation, it's basically saying Y is equal to 1.3 times X plus 10. So, 0 x 1.3 = 0 plus 10 = 10. Now we check the rest of the table. 5 x 1.3 = 6.5 + 10 = 16.5. 10 x 1.3 + 10 = 23. 15 x 1.3 + 10 = 29.5,  and 20 x 1.3 = 26 + 10= 36. The math matches with the table so we're done.

12×x-12×6=2×x-2×9

12x-72=2x-18

12x-2x= -18+72

10x = 54

x =54/10

x = (5)\4/10

Answer:

x = 12, y = 42

Step-by-step explanation:

6 is multiplied by 6 to get 36 (lot of sixes lol)

So multiply everything else by 6

2 x 6 = 12

7 x 6 = 42

The answer for the following question is 12

as

Circumference of the circle = 2TTr

= 2 x 22/7 x 12

= 44 / 7 x 12

= 75.4285714286

Answer:

False

Step-by-step explanation:

It is false because the graph of [tex]y=x^{2}[/tex] does not passes through the point [tex](16,4)[/tex].

x = 16

y = 4

Substitute

[tex]4=16^{2}[/tex]

[tex]4=256[/tex]

Since 4 is not equal to 256, the answer is false.

Answer:

i hope this helps because i have a dog too and it is a husky that is one-years-old. oh and it is false

Step-by-step explanation:

4≠224. ∴The functions whose graphs include the point (16, 4) is y = x−12.

Answer:

C) √3

tanθ = √3

Step-by-step explanation:

Step:-1

Given that  θ be an angle in standard position whose terminal side

Given that the angle

                 sinθ = [tex]\frac{-\sqrt{3} }{2}[/tex]

Given that the Opposite side  AB = [tex]\sqrt{3}[/tex]

                        Hypotensue     AC = 2

Step(ii):-

By using Pythagoras theorem

                        AC² = AB² +BC²

                        BC² = AC² - AB²

                       BC²  = 4 - (√3)²

                               = 4-3

                         BC = 1

    Adjacent side(BC)  = 1

Step(iiI):-

Given that 'θ' lies in the third quadrant so tanθ is positive

                     tanθ = [tex]\frac{AB}{BC} = \frac{\sqrt{3} }{1}[/tex]
