Jerónimo ha fabricado pequeñas pelotas típicas como la que se muestra en la figura 1 (en mi libro aparecen cuatro pelotas). Para cada pelota se emplean 216 centímetros cuadrados de tela típica determina el radio de la pelota y aproxima su valor al decimal cercano.
Expresión r = área superficial / 4 * pi elevado al cubo, permite determinar el radio de cada pelota. Les pido ayuda con esta tarea

Answers

Answer 1

Answer:

r = 4,2 cm

Step-by-step explanation:

El área de una pelota es la siguiente:

[tex] A = 4\pi r^{2} [/tex]   (1)

En donde:

A: es el área superficial = 216 cm²

r: es el radio =?

Resolviendo la ecuación (1) para r podemos determinar el radio de cada pelota:

[tex] r = \sqrt{\frac{A}{4\pi}} = \sqrt{\frac{216 cm^{2}}{4\pi}} = 4,2 cm [/tex]

Por lo tanto, el radio de cada pelota es de 4,2 cm.

Espero que te sea de utilidad!

Use the given conditions to write an equation for the line in​ point-slope form and general form. Passing through (-4,8) and parallel to the line whose equation is 3x-8y-7=0

Answers

Step-by-step explanation:

Hey there!

The equation of a st.line passing through point is;

(y - 8) = m1(x+4).........(i).

And another equation is;

3x - 8y - 7 =0.......(ii)

From equation (ii), we get;

[tex]slope(m2) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

[tex]m2 = \frac{ - 3}{ - 8} [/tex]

Therefore the slope is 3/8.

As they are parallel lines, their slopes are eaual.

i.e m1 = m2 = 3/8.

Putting value of slope (m1) in equation (i).

[tex](y - 8) = \frac{3}{8} (x + 4)[/tex]

Simplify them to get equation.

[tex]8(y - 8 ) = 3x + 12[/tex]

[tex]8y - 64 = 3x + 12[/tex]

[tex]3x - 8y + 12 + 64 = 0[/tex]

[tex]3x - 8y + 76 = 0[/tex]

Therefore therequired equation is 3x - 8y +76=0.

Hope it helps...

How do you divide decimals.

Answers

Answer:

we need to shift decimal then divide

Step-by-step explanation:

First we move the divisor (if its a decimal) to the right until there is no more dot. If your dividend is also a decimal you also need to move it to the right how many spaces you moved the divisor's.

Example:

923.56 ÷ 4.5

This means that we move the dot between 4 and 5 once. We do the same to 923.56.

This means our division problem will be

9235.6 ÷ 45.

Now just do the problem normally as you should.

You have a wooden rod which is 24 1/2 inches long. Carlos needs a piece which is 8 3/4 inches long and Amanda needs a piece which is 6 3/8 inches long. How long will the rod be after you cut those pieces to give to Carlos and Amanda?

Answers

Answer:

8 3/4 inches

Step-by-step explanation:

Total length of the rod = 24 1/2 inches

Carlos = 8 3/4 inches

Amanda = 6 3/8 inches

length of the rod remaining = Total length - ( Carlos + Amanda)

= 24 1/2 - (8 3/4 + 6 3/8)

= 49/2 - (35/4 + 51/8)

= 49/2 - ( 75+51/8)

= 49/2 - 126/8

= 196-126/8

= 70/8

= 8 6/8 inches

= 8 3/4 inches

Length of rod remaining = 8 3/4 inches

Complete question :

Point K on the number line shows Kelvin's score after the first round of a quiz: A number line is shown from negative 10 to 0 to positive 10. There are increments of 1 on either side of the number line. The even numbers are labeled on either side of the number line. Point K is shown on 3. In round 2, he lost 9 points. Which expression shows how many total points he has at the end of round 2? 3 + (−6) = −9, because −9 is 6 units to the left of 3 3 + 6 = −9, because −9 is 6 units to the left of 3 3 + (−9) = −6, because −6 is 9 units to the left of 3 3 + 9 = −6, because −6 is 9 units to the left of 3

Answer: 3 + (−9) = −6, because −6 is 9 units to the left of 3

Step-by-step explanation:

Given the following :

Width of number line = - 10 to + 10

Point K on the number line = +3 ( kelvin's score after the first round of quiz).

If Kelvin losses 9 points in round 2  = - 9

Hence at the end of round 2, He'll have a total of :

Point at the end of round 1 + point lost in round 2

y = 1/3x + 5 m b = (0, )​

Answers

Answer:

5

Step-by-step explanation:

When we have an equation in slope-intercept form, it's put in the form

[tex]y = mx+b[/tex]

Where m is the coefficient (the slope) and b is the y-intercept.

Since we are trying to find the y-intercept based on this equation (that's why it says [tex]b=[/tex] ), we can use the equation to find the y-intercept.

The slope is [tex]\frac{1}{3}[/tex] since that's the coefficient next to x.

The constant being added is 5, therefore this is the y-intercept.
