2(10 – 24x) + y2 What is X equals What is Y equals What is the answer

kakasveta [241]

Answer:

X= 5/12 + 1/24y

Y= -10 + 29x

Step-by-step explanation:

2(10- 24x)+ 2y 2(10- 24x)+ 2y

20 - 48x +2y 20 - 48x +2y

48x =20 +2y -2y = 20- 48x

/48 /48 /48 /-2 /-2 /-2

x= 5/12 + 1/24y y= -10 +29x

The volume of a sphere is 4/3pi cm^3 what is the diameter of the sphere?

aleksandrvk [35]

The Diameter of sphere is 2cm.

Step-by-step explanation:

Given,

Volume of sphere = $\frac{4}{3}\pi \ cm^3$

Let,

diameter = d

As we know,

Volume of sphere = $\frac{4}{3}\pi \ r^3$

Therefore,

$\frac{4}{3}\pi\ r^3 = \frac{4}{3}\pi \\Multiplying\ both\ sides\ by\ \frac{3}{4\pi }\\\frac{3}{4\pi }*\frac{4}{3}\pi \ r^3 = \frac{4}{3}\pi * \frac{3}{4\pi }\\r^3=1\\(r)^3=(1)^3\\r=1$

We know that,

Diameter = 2r

Diameter = 2*1

Diameter = 2 cm

The Diameter of sphere is 2cm.

A cylinder with a radius of 1 cm and a height of 21 cm has the same volume as a cone with a height of 7 cm. What is the radius o

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have r = 1cm and H = 21cm. Substitute:

$V=\pi(1^2)(21)=21\pi\ cm^3$

The formula of a cone:

$V=\dfrac{1}{3}\pi r^2H$

r - radius

H - height

We have V = 21π cm³ and H = 7cm. Substitute:

$\dfrac{1}{3}\pi(r^2)(7)=21\pi$ divide both sides by π

$\dfrac{1}{3}(7)(r^2)=21$ divide both sides by 7

$\dfrac{1}{3}r^2=3$ multiply both sides by 3

$r^2=9\to r=\sqrt9\\\\r=3\ cm$
