Answer:

3.92*10^3mm

Step-by-step explanation:

In the diagram it gives you 7900mm. There is a figure which was given underneath written 900mm. use 7900 to subtract 900 you will get 7000. Then you can use the Pythagoras theorem to solve it, with a= height, b=5800mm and c=7000mm where, a^2+b^2=c^2.

Answer:

3919 mm

Step-by-step explanation:

Length of hypotenuse = 7900 - 900 = 7000 mm

Base = 5800 mm

Let the height of the triangle be h mm

Therefore, by Pythagoras theorem:

$h = \sqrt{7000^2 - 5800^2}$

$h = \sqrt{49000000- 33,640,000}$

$h = \sqrt{15,360,000}$

$h = 3,919.18359\: mm$

$h = 3,919\: mm$

Encuentre el resultado de la diferencia de las fracciones: 9 /12 - 2/3=

Veronika [31]

Responder:

1/12

Explicación paso a paso:

Entonces multiplicamos 9 por 3 y obtenemos 27.

Luego multiplicamos 2 por 12 y obtenemos 24.

A continuación, le damos a ambos términos nuevos denominadores: 12 × 3 = 36.

Así que ahora nuestras fracciones se ven así:

Paso 2

Dado que nuestros denominadores coinciden, podemos restar los numeradores.

27 - 24 = 3

Entonces la respuesta es:

Paso 3

Por último, necesitamos simplificar la fracción, si es posible. ¿Se puede reducir a una fracción más simple?

Para averiguarlo, intentamos dividirlo por 2 ...

¡No! Así que ahora probamos con el siguiente número primo mayor, 3 ...

¿Son tanto el numerador como el denominador divisibles por 3? ¡Sí! Entonces lo reducimos:

÷ 3 =

What is 2 to the power of 4/3 equal to

Reika [66]

Answer:

<h2>Eksponent</h2>

$\sf{ \large{ \boxed{ \red{ {a}^{ \frac{n}{m} } = \sqrt[m]{ {a}^{n} } } } }}$

$\sf{ {2}^{ \frac{4}{3} } }$

$= \sqrt[3]{ {2}^{4} }$

$= \sqrt[3]{2 \times 2 \times 2 \times 2}$

$= \boxed {\bold{\sqrt[3]{16}(c.) }}$

Simplify the expression 4(6x)

xxMikexx [17]

All you have to do is multiply 4 × 6 to get your answer. So, 4 × 6 = 24, and considering we can't leave the variable out, we have to put it with our answer. Our answer is then 24x. Hint: Parentheses mean multiplication.

Explain why a positive times a negative is a negative number.

prohojiy [21]

Explanation:

This can be explained by thinking numbers on the number line as:

Lets take we have to multiply a positive number (say, 2) with a negative number say (-3)

2×(-3)

Suppose someone is standing at 0 on the number line and to go to cover -3 , the person moves 3 units in the left hand side. Since, we have to compute for 2×(-3), The person has to cover the same distance twice. At last, he will be standing at -6, which is a negative number.

A image is shown below to represent the same.

Thus, a positive times a negative is a negative number.

Please help thank you.

This problem can be completed in 2 ways. Both are acceptable.

Option 1:

This is an isosceles trapezoid that can be divided into a rectangle and two congruent triangles.

The area of the rectangle is the base times the height.

$9 \times 4=36$

The area of one of the triangles is half the base times the height.

$\dfrac{1}{2} \times 5 \times 4 = 10$

The other triangle must have that area too.

$36+10+10=56$

The area is 56 square centimeters.

Option 2:

We can use the area formula for the trapezoid.

$A=\dfrac{b_1+b_2}{2} \times h$

Where $b_1$ is the length of the shorter base
and $b_2$ is the length of the longer base
and $h$ is the height.

The length of the shorter base is 9.
The length of the longer base is 9+5+5, or 19.

The height is 4.

$A=\dfrac{9+19}{2} \times 4$

$=56$

Same answer. The area is 56 square centimeters.

Both options are two acceptable ways the problem can be tackled.
