Answer:
Step-by-step explanation:
Expresar lo siguiente como fracciones.
a) Los 4 meses del año
Hay 12 meses en un año. Entonces, la fracción de 4 meses de 12 meses en un año es:
= 4/12
= 1/3
b) Un día de la semana
Hay 7 días en una semana.
Así, la fracción de 1 día en una semana será:
= 1/7
c) Las tres provincias de la región Costa ecuatoriana
En la región de la Costa Ecuatoriana, hay cinco provincias presentes.
Ahora, la fracción de tres provincias del total de cinco provincias de la región de la Costa Ecuatoriana será:

A class of 25 children is having a pizza party. Each child will eat 3/8 of a pizza. How many pizzas do they need to order?
A. 8 pizza pies at 10 pc. per pie = 80 available pieces
B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.
c. 22 pieces are left over.
D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.
E. Solve the equation 58 = 5X by dividing both sides by 5.
WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.
Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.
Answer:
10 pizzas
Step-by-step explanation:
To find the answer for this question you need to multiply 3/8 by 25.
3/8 * 25 = 9.375
You can't buy .375 of a pizza so you round it up and get 10.

AABC - AA'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of and then rotating it about the origin by 180 degrees
AABC - AA'BºC, because AA'B'C' is obtained by dilating AABC by a scale factor of and then rotating it about the origin by 180 degrees
AABC - AA'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of and then rotating it about the origin by 90 degrees
3
Answer:
2nd choice
Step-by-step explanation:
1. dilation factor: 1/2
2. rotation: about origin anti-clockwise 180°
Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of 1/2 and then rotating it about the origin by 180 degrees.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
We have to find the statement which is correct for triangle ABC and triangle A'B'C'.
Let us find the coordinates of triangle ABC
A=(2, 2), B=(2, 10) and C=(8, 12)
After transformation the triangle A'B'C'.
Coordinates A' = (-1, -1), B(-1, 5) and C'(-4, 6)
The scale factor is 1/2.
A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.
Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of and then rotating it about the origin by 180 degrees.
Hence, Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of 1/2 and then rotating it about the origin by 180 degrees.

Write a polynomial that represents the area of the inner circle. Write your amswer in terms of pi
Answer:
(x²+8x+16)π in²
Step-by-step explanation:
Since were not given the diagram of the circle. Let's assume the radius of inner circle is x+4
radius r = x+4
Area of the circle = πr²
Area of the circle = π(x+4)²
Area of the circle = π(x+4)(x+4)
Area of the circle =π(x²+4x+4x+16)
Area of the circle = π(x²+8x+16)
Area of the inner circle in terms of pi is (x²+8x+16)π in²
