Answer:
2/5, option 4.
Step-by-step explanation:
When you are dividing 2 fractions, the first fraction stays the same, and the 2nd fraction becomes the reciprocal, and the division sign becomes a multiplication sign.
The reciprocal of 2/3 is 3/2.
Now you need to change the division sign to a multiplication sign.
The equation will now become 4/15 x 3/2.
4 times 3 is 12, and 15 times 2 is 30.
12/30 isn't an option, so you will need to simplify.
Find a common factor, then divide.
6 is a common factor, so you divide both 12 and 30 by 6, to get 2 and 5.
2/5 is what you are left with.
Option 4.
4/15 divided by 2/3 is 2/5.

Step-by-step explanation:
3x+9=90
subtract 9 from both sides
3x=90-9
3x=81
divide by 3
x= 27

Del enunciado: " De cada 2 conejos, hay 5 gallinas" ¿cuál es la razón entre gallinas y total de animales? *
Answers
Answer:
La razón entre el número de gallinas y el total de animales es: [tex]\frac{5}{7}[/tex]
Step-by-step explanation:
La razón es una comparación entre dos magnitudes comparables.
En otras palabras, la razón es el cociente entre dos números o dos cantidades comparables entre sí, expresado como fracción.
En este caso, la cantidad total de animales es la suma de la cantidad de conejos y la cantidad de gallinas:
2 conejos + 5 gallinas= 7 animales
Entonces la razón entre el número de gallinas y el total de animales es: [tex]\frac{5}{7}[/tex]

The perimeter of a rectangular field is 298 yards. If the width of the field is 63 yards, what is its length?
Answers
Answer:
The length is 86 yards.
Step-by-step explanation:
63 is the width so,
63 + 63 = 126
Now subtract this from the total perimeter,
298 - 126 = 172
and divide by 2 because there are sides with the same length
172/2 = 86
The length is 86.

Answers
Answer:
Use pythagorean theorem.
Step-by-step explanation:
The length of the shorter sides are 1 & 4
1^2+4^2=c^2
1+16=c^2
17=c^2
So, the length, rounded to the nearest whole inch, would be 4.
To find the perimeter, you need to find the side lengths first.
The short sides are 6 & 7.
6^2+7^2=c^2
36+49=c^2
85=c^2
So the length for that would be 8, in the nearest whole number.
Add all of the side lengths together.
6+7+8= 21
The perimeter is 21.

3) Arjun was shopping for avocados, which were listed $0.90 each. He brought six avocados to the checkout lane, where he learned that there was a sale on avocados. With the discount, he was charged $4.86 before tax. What was the percent discount on each avocado?
Answers
Answer:
Step-by-step explanation:
Total discount = 6×$0.90 - $4.86 = $0.54
discount each = $0.54/6 ≈ $0.09
$0.09/$0.90 = 0.10 = 10%
Carmen y Catalina comparan la nota que obtuvieron en su examen bimestral de Aritmética y mencionan lo siguiente: Nuestras notas juntas es igual a 34 puntos, pero se sabe que Carmen obtuvo 4 puntos más que Catalina. ¿Cuál es la nota de Catalina?
Answers
Answer:
La nota de Carolina es 15 puntos.
Step-by-step explanation:
Un sistema de ecuaciones lineales es un conjunto de ecuaciones lineales que tienen más de una incógnita, relacionadas mediante las ecuaciones.
En los sistemas de ecuaciones, se debe buscar los valores de las incógnitas. Al reemplazar en las ecuaciones, deben dar la solución planteada.
En este caso se debe plantear un sistema de ecuaciones, donde las incógnitas son:
x: nota de Carolinay: nota de CarmenAmbas notas juntas es igual a 34 puntos. Expresado matemáticamente es:
x + y= 34
Se sabe que Carmen obtuvo 4 puntos más que Catalina. Esto es:
y= x + 4
Entonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{x+y=34} \atop {y=x+4}} \right.[/tex]
A través del método de sustitución debes despejar una de las incógnitas en una de las ecuaciones y sustituir su valor en la siguiente. En este caso, ya tienes despejada la incógnita y en la segunda ecuación. Por lo que sustituyes esta expresión en la primer ecuación:
x+ x+4=34
Resolviendo obtienes:
x + x= 34 - 4
2*x=30
x= 30÷ 2
x=15
Sustituyendo este valor en la segunda ecuación obtienes:
y= x+4
y= 15 +4
y= 19
Recordando que "x" representa la nota de Carolina e "y" la nota de Carmen, entonces la nota de Carolina es 15 puntos y la nota de Carmen es 19 puntos.

Answers
Answer:
A = 139.25 cm^2
Step-by-step explanation:
The composite shape is made up of a square with side 10 cm and a semicircle with diameter 10 cm. The area of the composite shape is the sum of the two areas. The diameter of the semicircle is the side of the square, and the radius of the circle is half of the diameter.
A = s^2 + (1/2)(pi)r^2
r = d/2 = s/2
A = (10 cm)^2 + (1/2)(3.14)(10 cm/2)^2
A = 100 cm^2 + (1/2)(3.14)(25 cm^2)
A = 139.25 cm^2

acute angle
obtuse angle
straight angle
right angle
Answers
Answer:
Option D
A right angle
Step-by-step explanation:
in circle geometry, we have several theorems that govern angles formed by chords drawn in circles.
One of the theorems states that the angle subtended on the circumference of a circle by a chord which is drawn across the center of the circle (which is the diameter) equals 90 degrees. This means that it is a right-angle.
Analytically, we can also sketch out the problem and see that we can divide the shape formed by points BAC into an isosceles triangle. (The two radii forming the sides while the diameter forms the base). We can also run a bisector of the isosceles triangle through point A to meet the diameter. We can see that it forms two 45 by 45 degree right-angled triangles. Thus proving that angle BAC is indeed a right angle.
