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]

The translation of the given sentence into an equation is: 7(b + 3) = 1.

Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.

Thus, the sentence given can be translated as shown below:

The unknown number is represented as variable b.

"The sum of a number (b) and 3" would be translated as: b + 3.

"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).

Therefore, translating the whole sentence into an equation, we would have:

7(b + 3) = 1.

Thus, the translation of the given sentence into an equation is: 7(b + 3) = 1.

The pool is full for 4 hrs.

Add the rates of filling of the 2 filling pipes and

subtract the rate of draining of the emptying pipe;

1st pipe's rate: ( 1 pool filled ) / ( 3 h);

2nd pipe's rate: ( 1 pool filled ) / ( 6 h );

3rd pipe's rate of emptying: ( 1 pool emptied ) / ( 4 h);

Let t = the time in hrs to fill the pool with all 3 pipes open

1/3+16-1/4 = 1/t;

Multiply both sides by 24t;

t = 4 hrs

-21.     -40

y-intercept is where the line intersects y axis, which x = 0

so y-intercept is 2

The edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively

The formuka for the volume of a cube is expressed as;

Volume = a^3

Where 'a' is the length of it's edge

From the information given, we have that the volume of the cube has a value of 197 cubic meters.

Now, substitute the value of the volume

We have;

197 = a^3

Take the cube root of both sides

a = 5. 82 meters

The formula for area of the face of a cube is given as;

Area = 6a ^2

Area = 6(5.82)^2

Area = 6(33. 85)

Area = 203 square meters

Thus, the edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively

Based on the ratio, 5¹/₂ : 1¹/₂, the unit rate can be found to be so the statement is TRUE.

To find the unit rate of a ratio, you should divide the first number in the ratio by the second number in the ratio.

When given the ratio, 5¹/₂ : 1¹/₂, therefore, the unit rate is:

= 5¹/₂ ÷ 1¹/₂

= 11/2 ÷ 3/2

= 11/2 x 2/3

= 22 / 6

= 3.6667

= 3²/₃

In conclusion, the unit rate of 5¹/₂ : 1¹/₂ is 3²/₃.

Answer:

Step-by-step explanation:

Using a proportional relationship, the costs are given as follows:

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

A proportional relationship may also involve multiple variables, as is the case in this problem, in which the cost is a function of the number of bags of popcorn p and the number of drinks d.

The constants are the prices of each product, hence the function for the total cost of p bags of popcorn and d drinks is given by:

C(p,d) = 3.35p + 4d.

Hence, for 3 bags and 8 drinks, the cost is:

C(3,8) = 3.35(3) + 4(8) = $42.05.

5 yellow tiles should be removed.

The original ratio of red tiles to yellow tiles as per the question :Ratio = 6:15. Now, after removal of red tiles, the numerator of ratio will become = 6 - 2. The numerator of new ratio will be 4. For yellow tiles, let the number of yellow tiles removed be x. So, the denominator or new number of yellow tiles will be 15 - x.

Now, relating the two ratio -

6:15 = 4:(15 - x)

Performing cross-multiplication to find the value of x.

6 × (15 - x) = 4 × 15

Performing multiplication on both the Left Hand Side and Right Hand Side

90 - 6x = 60

6x = 90 - 60

Performing subtraction to find the value of x

6x = 30

x = [tex]\frac{30}{6}[/tex]

Since all numbers are positive, their sum or product can be a positive number but never negative or zero.

The equation in the form y = mx +b, where x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan is: y = (3/20)x + 32 and the total monthly cost is $173.75.

a. Equation

Slope = ( $123.5-$86)/(610-360)

Slope=37.5/250

Slope= 3/20

y = mx + b

Solve for "b"

$123.5 = (3/20)610 + b

$123.5  = 91.5 + b

b=$123.5-$91.5

b = 32

Equation:

y = (3/20)x + 32

b. Total cost

Total cost= (3/20)945+32

Total cost= 141.75+32

Total cost= $173.75

Therefore the equation in the form y = mx +b, where x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan is: y = (3/20)x + 32 and the total monthly cost is $173.75.

The area of the given parallelogram is: 9√3 sq. feet.

A parallelogram is a simple quadrilateral with two sets of parallel sides in Euclidean geometry. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

Area of a parallelogram = Base of the Parallelogram * Height

Now, given:

A parallelogram ABCD,

AB = 6 feet, AX = 3√3.   Angle A = 30°

To find: Area of the Parallelogram ABCD.

Finding: Here, AB = 6 feet = base

For height,

Height = perpendicular distance from X to AB

= AX(sinA)

Height = 3√3 (sin30) = 3√3 / 2

Thus, area of the parallelogram = [tex]\frac{3\sqrt{3}}{2}\times6= 9\sqrt{3}sq. feet.[/tex]

Hence, The area of the given parallelogram is: 9√3 sq. feet.
