a souvenir of the eiffel tower is scaled 1/80 at inch to 1 foot. if the total height of the tower is 1,069 feet, the approximate height of the souvenir of the eiffel tower to the nearest tenth is

Answers

Answer 1

well, let's convert 1 foot to inches, that'd be 12 inches per foot.

so we know that the souvenir is 1/80 in, to the actual of 12 inches on the Eiffel Tower, if the Tower itself is 1069 feet high, namely (1069)(12) inches, how high is the souvenir?

[tex]\begin{array}{ccll} \stackrel{in}{souvenir}&\stackrel{in}{actual}\\ \cline{1-2} \frac{1}{80}&12\\[1em] x&(1069)(12) \end{array}\implies \cfrac{ ~~ \frac{1}{80} ~~ }{x}~~ = ~~\cfrac{12}{(1069)(12)}\implies \cfrac{ ~~ \frac{1}{80} ~~ }{\frac{x}{1}}~~ = ~~\cfrac{12}{12828} \\\\\\ \cfrac{1}{80}\cdot \cfrac{1}{x}=\cfrac{1}{1069}\implies \cfrac{1}{80x}=\cfrac{1}{1069}\implies 1069=80x\implies \cfrac{1069}{80}=x\implies 13.4\approx x[/tex]

a right circular cylinder, a, has radius r and height h. another right circular cylinder, b, has radius 3r and height 2h. what is the ratio of the volume of a to the volume of b ?

Answers

The ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b is 1: 18.

According to the given question.

We have two right circular cylinder, a nd b.

Also,

The radius of right circular cylinder, a is r.

The height of the right circular cylinder, a is h.

The radius of the right circular cylinder, b is 3r.

And the height of the right circular cylinder, b is 2h.

As we know that, the volume of a cylinder can be calculated using the formula V=πr^2(h). Where r is the radius and h is the height of the cylinder.

So, the volume of the right circular cylinder a  = πr^2h

And, the volume of the right circular cylinder b = π(3r)^2(2h) = 18hr^2π

Therefore,

The ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b

= πr^2h/18hr^2π

= 1:18

Hence, the ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b is 1: 18.

Abigail redecorates her house. A scale drawing of her house can be seen below. if each 6 cm on the scale drawing equals 12 ft, what are the actual dimensions of Abigail's house?

Answers

The actual dimensions of Abigail's house are 20ft, 14ft, 18ft, 16ft, 18ft.

For 6 cm in drawing his house is 12 ft on scale which is twice the drawing

This means the scale factor is 2

Therefore,

10cm = 2 × 10 = 20ft

7cm = 2 × 7 = 14ft

9cm = 2 × 9 = 18ft

8cm = 2 × 8 = 16ft

9cm = 2 × 9 = 18ft

What is scale factor?

The scale factor is the quantity that is multiplied by an object's scale to produce a separate object that has the same appearance but is a different size—either scaled up or scaled down.

The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?


A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 59 degree Celsius.A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.A temperature increase of 59 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.


A) I only

B) II only

C) III only

D) I and II only


Who ever answers this first correctly and show explanation gets brainliest

Answers

ANSWER:

d

ANSWER EXPLANATION: Think of the equation as an equation for a line

y=mx+b

where in this case

C=59(F−32)

or

C=59F−59(32)

You can see the slope of the graph is 59, which means that for an increase of 1 degree Fahrenheit, the increase is 59 of 1 degree Celsius.

C=59(F)

C=59(1)=59

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 95 degrees Fahrenheit.

C=59(F)

1=59(F)

(F)=95

Since 95 = 1.8, statement II is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of 59 degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

C=59(F)

C=59(59)

C=2581(whichis≠1)

An increase of 59 degree Fahrenheit leads to an increase of 2581, not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.

Answer:

D) i and ii

Step-by-step explanation:



from given equation, we can simplify =
1.8 C = F-32 .....................i
F = 1.8 C +32 ....................ii




now,  from (i)
1.8 (C+1 ) = 1.8 C + 1.8 = (F +1.8) -3.2
so increasing 1 C  equivalent to 1.8 F ........... iii

from iii,
increasing (1/1.8) C or (5/9) C equivalent to (1.8/1.8) F or 1 F


increasing (5/9)/ (5/9) or (25/81) C equivalent to 5/9 degree F
(so given iii become false)


only i and ii is true = D

Answers

Answer:

Because the graph has the parabol shape, so the equation of it has the function:

y = ax² + bx + c

Because the parabol has a peak at point (0; 9)

=> 9 = a.0² + b.0 + c

=> c = 9

=> The parabol has a function:

y = ax² + bx + 9

Because the parabol goes through point (3; 0)

=> 0 = a.3² + b.3 + 9

=> 9a + 3b = - 9 (1)

Because the parabol goes through point (-3; 0)

=> 0 = a.(- 3)² + b.(- 3) + 9

=> 9a - 3b = - 9 (2)

Plus (1) and (2):

=> 18.a = - 18

=> a = - 1

Substitute the result on (1)

=> b = 0

=> The function of the parabol: y = - x² + 9

=> a = - 1

=> Choose A. - 1

If mary wants to bake muffins .she she has 3kg of flour. if a tray of 6 muffins 200g of of flour how many trays will she bake

Answers

Mary will bake 15 trays.

Firstly converting the amount of flour into grams that Mary has.

As per the known facts 1 kilogram = 1000 grams.

So, amount of flour in grams  = 3 × 1000

Performing multiplication to calculate amount of flour

Amount of flour in grams = 3000 grams.

Now, 200 grams flour is required by number of trays = 1

So, 3000 grams flour will be required by number of trays = (1÷200)×3000

Performing multiplication and division to find the number of trays that can be baked

Number of trays = 15

Hence, Mary can bake 15 trays of muffins with 3 kilograms of flour.

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

Dimension in real = 6 feet

Since,

1 feet = 12 inches

6 feet = 72 inches

Dimension in drawing = 3 inches.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the functions f and g

f  = {(0, 1), (2, 4), (4, 6), (6, 8)}

g = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)}

Now,

f + g is nothing but the sum of x and y corresponding

For example (0,1) + (2,5) = (2 ,6)

Similarly  (0,1) - (2,5) = (-2,-4)

So,

(f + g) = { (2,6) ,(6,11) ,(9,14),(12,17) }

(f - g) = { (-2,-4) ,(-2,-3) ,(-1,-2),(0,-1)}

To change the order of operations in a formula, use parentheses around the part of the formula you want to calculate first.

Parentheses allow you to group elements in a cell.  This allows you to create more complex and more powerful formulas.

Consider the expression 6+4*2.

The above formula gives result as 14 because Excel performs multiplication before addition. The formula multiplies 4 by 2 and then adds 6 to the result.

Now consider the expression (6+4)*2.

Answers

Answer: Adult tickets were sold = 325

Step-by-step explanation:

Let, A = Number of adult tickets sold

S = Number of student tickets sold

Total number of tickets=599

Therefore:

                           A + S = 599

If, there were 51 fewer student tickets sold them adult tickets.

Since,

                            S=A-51

So, substitute A-51 for the value of the first equation.    

                            A+S=599    

                        A+(A-51)=599

Expanding to get:

                            2A-51=599

Solve to get:

                          2A=599+512

                          A=650A
