Un recipiente cilíndrico tiene un diámetro de 160cm. y la misma altura. ¿Cuánto litros de agua puede caber?

Len [333]

Respuesta:

3215360 cm³

Explicación paso a paso:

Dado que :

Radio = 160/2 = 80 cm

Altura, h = 160 cm

Volumen de un cilindro = πr²h

Volumen del cilindro = π * 80² * 160

Volumen = 3215360 cm³

Which of the following is the complete factorization of 10x - 3 - 3x2? -(3x + 1)(x - 3) -(3x - 1)(x - 3) (3x - 1)(x + 3)

qaws [65]

Answer:

$=-\left(3x-1\right)\left(x-3\right)$

Step-by-step explanation:

$10x-3-3x^2\\\mathrm{Factor\:out\:common\:term\:}-1\\=-\left(3x^2-10x+3\right)\\\mathrm{Factor}\:3x^2-10x+3:\quad \left(3x-1\right)\left(x-3\right)\\3x^2-10x+3\\\mathrm{Write\:in\:the\:standard\:form}\:ax^2+bx+c\\=3x^2-10x+3\\\mathrm{Break\:the\:expression\:into\:groups}\\=\left(3x^2-x\right)+\left(-9x+3\right)\\\mathrm{Factor\:out\:}x\mathrm{\:from\:}3x^2-x\mathrm{:\quad }x\left(3x-1\right)\\3x^2-x\\\mathrm{Apply\:exponent\:rule}:\quad \:a^{b+c}=a^ba^c\\x^2=xx\\=3xx-x$

$\mathrm{Factor\:out\:common\:term\:}x\\=x\left(3x-1\right)\\\mathrm{Factor\:out\:}-3\mathrm{\:from\:}-9x+3\mathrm{:\quad }-3\left(3x-1\right)\\-9x+3\\\mathrm{Rewrite\:}9\mathrm{\:as\:}3\cdot \:3\\=-3\cdot \:3x+3\\\mathrm{Factor\:out\:common\:term\:}-3\\=-3\left(3x-1\right)\\=x\left(3x-1\right)-3\left(3x-1\right)\\\mathrm{Factor\:out\:common\:term\:}3x-1\\=\left(3x-1\right)\left(x-3\right)\\=-\left(3x-1\right)\left(x-3\right)$

Given: KLMN is a trapezoid m∠N = m∠KML

horrorfan [7]

Answer:

The length of sides KM, LM and KN are $\sqrt{109}, \frac{48}{5}$ and 16 respectively. The area of KLMN is $\frac{192\sqrt{5}}{5}$ square unit.

Step-by-step explanation:

According to given information: KLMN is a trapezoid, ∠N= ∠KML, $\frac{LM}{KN}=\frac{3}{5}$ , ME ⊥ KN, KE=8 $ME=3\sqrt{5}$ .

Use pythagoras theorem is triangle EKM

$Hypotenuse^2=base^2+perpendicular^2$

$(KM)^2=(KE)^2+(ME)^2$

$(KM)^2=(8)^2+(3\sqrt{5})^2$

$KM^2=64+9(5)$

$KM=\sqrt{109}$

Let angle N and angle KML be θ.

Since angle KML and angle MKE are alternate interior angles, therefore angle MKE is θ.

In triangle KME,

$\tan\theta=\frac{3\sqrt{5} }{8}$ .... (1)

In triangle KNE,

$\tan\theta=\frac{3\sqrt{5} }{EN}$ .... (2)

Equate (1) and (2),

$\frac{3\sqrt{5} }{8}=\frac{3\sqrt{5} }{EN}$

$EN=8$

The length of side KN is

$KN=KE+EN=8+8=16$

Sides LM:KN are in the ratio 3:5. Let the side lengths are 3x and 5x respectively.

$5x=16$

$x=\frac{16}{5}$

$3x=3\times \frac{16}{5}=\frac{48}{5}$

The area of KLMN is

$Area=\frac{1}{2}(b_1+b_2)h$

$A=\frac{1}{2}\times (LM+KN)\times ME$

$A=\frac{1}{2}\times (\frac{48}{5}+16)\times 3\sqrt{5}$

$A=\frac{192\sqrt{5}}{5}$

Therefore length of sides KM, LM and KN are $\sqrt{109}, \frac{48}{5}$ and 16 respectively. The area of KLMN is $\frac{192\sqrt{5}}{5}$ square unit.

devlian [24]

Answer:

C. 98

Step-by-step explanation:

If you add all of his previous test scores and go through the list of numbers you get C.98 as the answer. I added all of his test scores plus 98 which equals 630 divided by 7 (because if he got a 98 there would be 7 test scores) you would get 90 or an A average.
