16. Which is greater, 4^-2 or
2^-4? How do you know?

Answers

Answer 1

Answer: if this is a fraction 4\2 is greater

Step-by-step explanation: First you need same denominaters the lest coomon is four 2 over 4 is fine 4 over 2 two times 2 is 4 and 4 times 4 is 16 with will leave you with 16/4 or 2/4 simplfied 4/2 is greater

Answer 2

Answer:

The expressions are equal.

Step-by-step explanation:

Notice that [tex]a^{-b}=\frac{1}{a^b}[/tex] for all (real) [tex]a,b[/tex]. So [tex]4^{-2}=\frac{1}{4^2} = \frac{1}{16}[/tex] and [tex]2^{-4} = \frac{1}{2^4} = \frac{1}{16}[/tex]. Therefore, the expressions are equal.

1,200 divided by 5 times 10

Answers

Answer:

24

Step-by-step explanation:

Multiply 5 * 10

5 * 10 = 50

1,200/50 = 24

The result of 1,200 divided by 5 times 10 is 2,400.

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1,200 ÷ 5 × 10

Step 1: Perform division first:

1,200 ÷ 5 = 240

Step 2: Perform multiplication:

240 × 10 = 2,400

So, the result of 1,200 divided by 5 times 10 is 2,400.

Alejandro put down a deposit of $75.00 on a graduation ring, and he then began making weekly payments of $12.50 until the ring was fully
paid for.
If the price of the graduation ring was $225.00, how many weekly payments of $12.50 did Alejandro make?

Answers

Answer:

12 weekly payments

Step-by-step explanation:

Here, we want to get the number of weeks in which he made payment for the ring

We start by subtracting the deposit,

That would be;

225-75 = 150

Now, we proceed to divide what ie left by the weekly payment to get the number of weeks

That would be;

150/12.5 = 12

Answer:

12 weekly payments

Step-by-step explanation:

if AC is AB and BC put together you add those and put them equal to the whole. Solve and you find X. You take X plug it into the BC equation (3X+5) and you find the length of BC

Answer:

x = 4, BC = 17

Step-by-step explanation:

AC = AB + BC , substitute values

7x - 3 = 2x + 3x + 5

7x - 3 = 5x + 5 ( subtract 5x from both sides )

2x - 3 = 5 ( add 3 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Step-by-step explanation:

The parameters of the triangle having bisected angle are;

The length of the opposite and adjacent side of one of the halves of the bisected angle = 6 and 14 respectively

The length of the opposite and adjacent side of the other half of the bisected angle = (3·x - 12) and 21 respectively

By the angle bisector theorem, we have;

[tex]\dfrac{14}{6} = \dfrac{21}{3\cdot x - 12}[/tex]

Simplifying, we get;

[tex]\dfrac{14}{6} = \dfrac{2 \times 7}{2 \times 3} = \dfrac{7}{3}[/tex]

[tex]\dfrac{21}{3\cdot x - 12} = \dfrac{3 \times 7}{3 \times (x - 4)} = \dfrac{7}{x - 4}[/tex]

[tex]\dfrac{7}{3} = \dfrac{7}{ x - 4}[/tex]

7 × (x - 4) = 3 × 7

∴ x - 4 = 3

x = 3 + 4 = 7

x = 7.

Un agricultor planta 720 naranjos, 250 matas de mandarina, 360 de mamon y 480 de níspero en el menor número posible de hileras, cada una con el mismo número de árboles, sin mezclarlos. A) ¿Cuántos arboles tiene cada hilera? B) ¿Cuántas hileras necesita?

Answers

Answer:

A) Se requiere 10 árboles por hilera.

B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Step-by-step explanation:

A) A continuación, realizamos la descomposición factorial de cada número:

Naranjos

[tex]720 = 2 \times 2 \times 2 \times 2 \times 3\times 3\times 5[/tex]

[tex]720 = 2^{4}\times 3^{2}\times 5[/tex]

Mandarinos

[tex]250 = 2\times 5\times 5\times 5[/tex]

[tex]250 = 2\times 5^{3}[/tex]

Mamoneros

[tex]360 = 2\times 2\times 2\times 3\times 3\times 5[/tex]

[tex]360 = 2^{3}\times 3^{2}\times 5[/tex]

Nísperos

[tex]480 = 2\times 2\times 2\times 2 \times 2\times 3\times 5[/tex]

[tex]480 = 2^{5}\times 3\times 5[/tex]

El máximo común divisor de los cuatro números representa el número de árboles de cada hilera considerando el menor número posible de hileras, cuyo valor es [tex]2\times 5 = 10[/tex]. Se requiere 10 árboles por hilera.

B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por el resultado del punto anterior:

Naranjos

[tex]x = \frac{720}{10}[/tex]

[tex]x= 72[/tex]

Mandarinos

[tex]x = \frac{250}{10}[/tex]

[tex]x = 25[/tex]

Mamoneros

[tex]x = \frac{360}{10}[/tex]

[tex]x = 36[/tex]

Nísperos

[tex]x = \frac{480}{10 }[/tex]

[tex]x = 48[/tex]

El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Teniendo en cuenta la definición de m.c.m:

A) Se requieren 10 árboles por hilera.

B) El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

A) Para hallar la cantidad de árboles que posee cada hilera debes hallas el m.c.d entre 720, 250, 360 y 480.

El máximo común divisor, m.c.d., de dos o más números es el mayor número que divide a todos de manera exacta, es decir, es el mayor de los divisores que tienen en común dos o más números.

El mínimo común múltiplo se suele expresar con las siglas m.c.d. (a, b), siendo a y b los números.

Para calcular el mínimo común múltiplo de dos o más números, de debe descomponer los números en factores primos (son los números que sólo son divisibles por sí mismos o por el número 1). En este caso:

720= 2×2×2×2×3×3×5= 2⁴×3²×5

250=2×5×5×5= 2×5³

360=2×2×2×3×3×5= 2³×3²×5

480=2×2×2×2×2×3×5= 2⁵×3×5

El mínimo común múltiplo se obtiene escogiendo todos los factores comunes, elevados a la menor potencia. Es decir, se escoge aquellos factores que aparecen en todas las descomposiciones la menor cantidad de veces. En este caso:

mcd (720,250,360, 480)= 2×5= 10

Entonces, se requiere 10 árboles por hilera.

B) El número de hileras por árbol se determina al dividir el total de cada tipo de árbol por la cantidad de árboles que se requiere por hilera:

Naranjos: 720÷10= 72

Matas de mandarina: 250÷10= 25

Mamon: 360÷10= 36

Níspero: 480÷10= 48

El agricultor necesita 72 hileras de naranjos, 25 hileras de mandarinos, 36 hileras de mamoneros y 48 hileras de nísperos.

Answers

Answer:

MC is 10 in.

Step-by-step explanation:

The given parameters for the triangle ΔABC are;

m∠B = 90°

m∠C = 15°

M ∈ BC

m∠BAM = 60°

AM = 10 in.

From the given information, ΔABC is drawn using Microsoft Visio, from which we have ΔACM

m∠CAM = 75° - 60° = 15° (By angle addition postulate)

m∠CAM = 15° = m∠C, therefore, ΔACM is an isosceles triangle with base angles, m∠CAM and m∠C each equal to 15°

AM = 10 in. = MC, by definition of isosceles triangle

∴ MC = 10 in.
