En un acuario compraron 30 peces y 18 tortugas de agua. Los van a colocar en peceras. Cada una tiene que haber la misma cantidad de peces, la misma cantidad de tortugas y la mayor cantidad de animales posibles ¿cuantas peceras compraron? ¿cuantos peces compraron? ¿cuantos peces y tortugas puede tener cada pecera? Diganme porfaa
Answers
Answer:
a) ¿Cuántas peceras compraron?
Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.
b) ¿Cuántos peces y tortugas puede tener cada tanque?
3 peces por tanque
5 tortugas de agua por tanque
Step-by-step explanation:
Resolvemos la pregunta anterior utilizando el cálculo de múltiplo común más bajo
En un acuario compraron 30 peces y 18 tortugas de agua.
Encuentre y enumere los múltiplos de cada número hasta encontrar el primer múltiplo común. Este es el mínimo común múltiplo.
El mínimo común múltiplo es el número de tanques
Múltiplos de 18:
18, 36, 54, 72, 90, 108, 126
Múltiplos de 30:
30, 60, 90, 120, 150
Por lo tanto,
MCM (18; 30) = 90
a) ¿Cuántas peceras compraron?
Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.
b) ¿Cuántos peces y tortugas puede tener cada tanque?
El número de peces que puede tener cada tanque = Número de tanques / Número de peces
= 90/30
= 3 peces por tanque
El número de tortugas de agua que puede tener cada tanque =
Número de tanques / Número de tortugas de agua
= 90/18
= 5 tortugas de agua por tanque

"sqrt" is shorthand for "square root". If you need x as well, it is x = 18
=============================================================
Explanation:
This is a 30-60-90 triangle. The hypotenuse is twice that of the short leg, so the hypotenuse is x = 2*9 = 18 units.
The long leg is sqrt(3) times the short leg, so y = 9sqrt(3)
You could use the trig ratios (sine, cosine, tangent) to help find these values.

5x - 7 = 2x + 11
x = ?
Answers
Answer:
6
Step-by-step explanation:
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-7 + 5x + -2x = 11 + 2x + -2x
Combine like terms: 5x + -2x = 3x
-7 + 3x = 11 + 2x + -2x
Combine like terms: 2x + -2x = 0
-7 + 3x = 11 + 0
-7 + 3x = 11
Add '7' to each side of the equation.
-7 + 7 + 3x = 11 + 7
Combine like terms: -7 + 7 = 0
0 + 3x = 11 + 7
3x = 11 + 7
Combine like terms: 11 + 7 = 18
3x = 18
Divide each side by '3'.
x = 6
Simplifying
x = 6
Answer:
x=6
Step-by-step explanation:
Solve 5x−7=2x+11.
Subtract 2x from both sides.
5x−7−2x=2x+11−2x
3x−7=11
Add 7 to both sides.
3x−7+7=11+7
3x=18
Divide both sides by 3.

If it is rotated 180° to form triangle R'S'T', enter the coordinates of T'.

Answers
Answer:
Step-by-step explanation:
In the absence of additional information, will assume rotation is about the origin.
A 180° rotation about the origin has the equation
(x,y) => (-x,-y)
Therefore
R(-10, 5.6) => R'(10, -5.6)
S(0, 7) => S'(0, -7)
T(-6, -34) => T'(6, 34)

The class party started with five chocolate cakes cut in fourths as shown below in the example.
Answers
============================================================
Explanation:
One large square cake cuts into 4 smaller slices
Since we have 5 such cakes that are cut like this, we have 5*4 = 20 slices all together.
Count the number of dark shaded slices that are shown in the lower diagram. We have 4+3+4+2 = 7+6 = 13 slices of cake that are left over. This must mean the class ate 20-13 = 7 slices.
The fraction of the cakes eaten is 7/20
Notes:
7/20 = 35/100 = 0.35 = 35%The fraction 7/20 cannot be reduced further because 7 and 20 have no common factors other than 1.Explanation needed
find the image of (1 2) after a reflection about y=-1 followed by a reflection about y=1
Answers
Answer:
A‘‘ (1,6)
Step-by-step explanation:
after a reflection about a horizontal line the x coordinates remain the same
the middle point of the segment AA’ lies on the line so it has y = -1
so we have
(y+y’)/2 = -1
y’ = -2 -y
y‘ = -2 -2 = -4
so A‘ (1,-4)
we can use the same reasoning to find the reflection about y = 1
x‘ = x
(y + y’)/2 = 1
y‘ = 2+4
y’ = 6

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio, si avanza medio kilómetro en bus y lo demás a pie ¿Cuánto le falta caminar?
Answers
Answer:
Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.
Step-by-step explanation:
Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción [tex]\frac{2}{3}[/tex] .
El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción [tex]\frac{1}{2}[/tex], por lo tanto un medio es la mitad de una cantidad. Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:
[tex]\frac{1}{2} *\frac{2}{3}[/tex]
Resolviendo:
[tex]\frac{1}{2} *\frac{2}{3} =\frac{1*2}{2*3} =\frac{2}{6} =\frac{1}{3}[/tex]
Entonces, la distancia recorrida en bus es [tex]\frac{1}{3}[/tex] de kilómetro.
Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:
[tex]\frac{2}{3} - \frac{1}{3}[/tex]
Resolviendo:
[tex]\frac{2}{3} - \frac{1}{3}=\frac{2-1}{3} =\frac{1}{3}[/tex]
Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.

90 perimeter
When you hear that a TV is 40 inches, the length from one corner to the opposite corner diagonally is 40 inches. To solve, we use formula for hypotenuse, a^2 + b^2 = c^2.
20^2 + 25^2 = 32.02^2.
If that is what they mean by size, your answer is 32.02. However, size could refer to the area of the screen, which is calculated by length * width.
20 * 25 = 500
The answer in this case is 500.

Answers
center = (3, -1)

==================================================
Explanation:
Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2
Then compare to the general form (x-h)^2+(y-k)^2 = r^2
You should find that h = 3, k = -1 and r = 3.
The center is (h, k) = (3,-1) and the radius is r = 3.
