The simplest ratio of squares to total shapes is 1 : 3
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
What is a square?A square is defined as a polygon that has four sides and is a closed, two-dimensional (2D) object. A square has equal and parallel sides on all four sides.
The area of a square is equal to the squared of sides or the multiplication of two sides.
Given that there are 3 squares and 6 triangles.
To determine the simplest ratio of squares to total shapes
The number of squares = 3
The number of triangles = 6
The number of total shapes = 3 + 6 = 9
So, the simplest ratio of squares to total shapes = 3/9
The simplest ratio of squares to total shapes = 1/3
Hence, the simplest ratio of squares to total shapes is 1 : 3

El boleto de entrada de una funcion de teatro es de $175.00para nuños y $200para adultos a la funcion entran 470 asistentes recaudandose $88,250.00 ¿Cual es el sistema de ecuaciones para calcular la cantidad de niños y adultosque acudieron a la funcion
Answer:
El sistema de ecuaciones para calcular la cantidad de niños y adultos que acudieron a la función es:
x+y=270
175x+200y=88,250
Step-by-step explanation:
La información proporcionada indica que a la función entran 470 asistentes entre adultos y niños y con esta información puedes decir que la suma de niños y adultos que entran a la función es igual a 470:
x+y=270, donde
x es el número de niños
y es el número de adultos
Además, se indica que se recaudaron $88,250 y tienes los precios de cada entrada por lo que puedes expresar que la suma de los resultados de multiplicar cada precio por la cantidad de personas que entraron por ese precio es igual a $88,250:
175x+200y=88,250
De acuerdo a esto, la respuesta es que el sistema de ecuaciones para calcular la cantidad de niños y adultos que acudieron a la función es:
x+y=270
175x+200y=88,250

Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years. $
Answer:
$22,400.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 14%/100 = 0.14 per year,
then, solving our equation
I = 40000 × 0.14 × 4 = 22400
I = $ 22,400.00
The simple interest accumulated
on a principal of $ 40,000.00
at a rate of 14% per year
for 4 years is $ 22,400.00.

Which of the following complex numbers is
equivalent to (3-1) 27 (Note: 1==1)
A)..8.-..6i.
2-2ab+be
0
B) 8+ 6i
(-)
C) 10 - 6i
9 -6 (-i) +-
D-10 +61
Answer:
[tex]8-6i[/tex]
Step-by-step explanation:
Multiply out [tex](3-i)^2[/tex] in order to find out which expression it is equivalent to.
1) Since the whole quantity is squared, write it out as [tex](3-i)(3-i)[/tex].
[tex](3-i)^2\\(3-i)(3-i)[/tex]
2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.
[tex](3-i)(3-i)\\9 - 3i - 3i + i^2[/tex]
[tex]9 - 6i + i^2[/tex]
3) [tex]i = \sqrt{-1}[/tex], so [tex]i ^2[/tex] must be [tex](\sqrt{-1} )(\sqrt{-1})[/tex]. Thus, [tex]i^2[/tex] is equivalent to -1. Knowing this, simplify and combine like terms.
[tex]9 - 6i + ((-\sqrt{1} )(\sqrt{-1} ))[/tex]
[tex]9 - 6i -1\\8 - 6i[/tex]
Thus, it is equivalent to [tex]8 - 6i[/tex] .

Q11 - 12 sidesQ12 - 10 sidesStep-by-step explanation:
Use the formula for sum of interior angles of a regular polygon:
S = 180(n - 2)Each angle A measures:
S/n = 180(n - 2)/nA = 180(n - 2)nAn = 180n - 360(180 - A)n = 360n = 360/(180 - A)Question 11Each angle is 150, then finding n:
n = 360/(180 - 150)n = 360/30n = 12Question 12Each angle is 144, find n:
n = 360/(180 - 144)n = 360/36n = 10Answer:

Answer:
y = -5x - 5
Step-by-step explanation:
to get the coefficient of the 'x' term (which is the slope) you take the difference of the y-values [5 - (-5)] divided by the difference of the x-values (-2 - 0)
so slope = 10/-2 or -5/1
to get the -5, this is the point at which the line intersects the y-axis; from looking at the graph you can see this is -5

Step-by-step explanation:
Your table is poorly presented
Given
x y
[tex]\begin{array}{cc} {3} & {1.47} \ \\ {5} & {2.45} \ \\ {9} & {4.41} \ \ \end{array}[/tex]
First, we calculate the constant of proportionality (k)
[tex]k = \frac{y}{x}[/tex]
For (3,1.47)
[tex]k = \frac{1.47}{3}[/tex]
[tex]k = 0.49[/tex]
For (5,2.45)
[tex]k = \frac{2.45}{5}[/tex]
[tex]k = 0.49[/tex]
For (9,4.41)
[tex]k = \frac{4.41}{9}[/tex]
[tex]k = 0.49[/tex]
From the above calculations, the constant of proportionality is 0.49.
So, the usable rows must also have 0.49 as their constant of proportionality
Choice A
[tex](x,y) = (2,0.98)[/tex]
[tex]k = \frac{0.98}{2}[/tex]
[tex]k = 0.49[/tex] --- This is usable
Choice B
[tex](x,y) = (7,4.45)[/tex]
[tex]k = \frac{4.45}{7}[/tex]
[tex]k = 0.64[/tex] --- This is not usable
Choice C
[tex](x,y) = (6,2.94)[/tex]
[tex]k = \frac{2.94}{6}[/tex]
[tex]k = 0.49[/tex] --- This is usable
Choice D
[tex](x,y) = (1,0.54)[/tex]
[tex]k = \frac{0.54}{1}[/tex]
[tex]k = 0.54[/tex] ---- This is not usable
Choice E
[tex](x,y) = (8,3.92)[/tex]
[tex]k = \frac{3.92}{8}[/tex]
[tex]k = 0.49[/tex] --- This is usable

Bob's dog needs medication. He told the veterinarian that the dog weighs 30lbs . The medicine is measured as 16mg for each kilogram of the animal's mass. How much medicine should be given to Bob's dog?
Use 1lb=0.45 kg and do not round any computations.
Answer:
Bob's dog should be given 216 mg of medicine.
Step-by-step explanation:
Given that:
Weight of dog = 30 lbs
We know that:
1 lb = 0.45 kg
30 lbs = 0.45 * 30 kg
30 lbs = 13.5 kg
Medicine for each kilogram of weight = 16 mg
1 kilogram = 16 mg
13.5 kg = 16 * 13.5 mg
13.5 kg = 216 mg
Hence,
Bob's dog should be given 216 mg of medicine.
Write the exponential equation for this scenario. Mike buys a car for $45,000.00. The cars value depreciates (loses value) at a rate of 18% per year.
Answer:
[tex]A=45000(0.82)^t[/tex]
Step-by-step explanation:
Given data
P= 45,000
rate= 18%
Recall the expression for the compound interest
[tex]A=P(1+r)^t[/tex]
Since we are talking of depreciation
[tex]A=P(1-r)^t[/tex]
Substitute
[tex]A=45000(1-0.18)^t\\\\A=45000(0.82)^t[/tex]
Hence the exponential function is
[tex]A=45000(0.82)^t[/tex]
The table shows the cost of a sandwich and a drink at a local cafeteria. how much more does a sandwich cost than a drink
Answer:
$2.02
Step-by-step explanation:
1.50/2 = 0.75
0.75 - 0.49 = 0.26
Sandwich = 2(0.75)+1.5 = 3
Drink = (0.49) + 0.49 = 0.98
3 - 0.98 = 2.02

The rectangular floor of a classroom is 30 feet in length and 38 feet in width. A scale drawing of the floor has a length of 15 inches. What is the perimeter, in inches, of the floor in the scale drawing?
Length of the rectangular floor of a classroom = 30 feet
Width of the rectangular floor of a classroom = 38 feet
Length of the floor in a scale drawing = 15 inches
Which means, 1 inch is equal to :
[tex] = \tt\frac{30}{15} [/tex]
[tex] = \tt2 \: feet[/tex]
Thus, 1 inch in the drawing is equivalent to 2 feet of the floor.
Then, width of floor in the scale drawing :
[tex] = \tt\frac{38}{2} [/tex]
[tex] = \tt19 \: inches[/tex]
Thus, the width of the floor in the scale drawing = 19 inches
Perimeter of the floor in the scale drawing :
[tex]= \tt2(length + breadth)[/tex]
[tex] =\tt 2(15 + 19)[/tex]
[tex] =\tt 2(34)[/tex]
[tex] =\color{plum}\tt68 \: inches[/tex]
Thus, perimeter = 68 inches
Therefore, the perimeter of the rectangular floor in the scale drawing = 68 inches
Answer:
P = 2L + 2W
W = 5
P = 2L + 2(5) = 16
2L + 10 = 16
2L = 6
L = 3 ft
Step-by-step explanation:
So we know that the perimeter of a rectangle= 2 (length + width).
We set up the equation so it's 16= 2 (length+ 5)
Divide both sides by 2, so 8 = length + 5.
Subtract 5 from both sides and you get length = 3
