What is the solution of the following system of equations ? y- 2x and= 6 , y - 4x =0

Sveta_85 [38]

Answer:

x=3 and y=12

Step-by-step explanation:

$y-2x=6$ equation:1

$y-4x=0$ equation:2

Solving equation:1 for 'y' in terms of x

$y=6+2x$ equation:3

Putting 'y' in equation:2 which will make the equation of the single variable

$y-4x=0$

$6+2x-4x=0\\-2x=-6\\x=3$

Putting value of 'x' in equation:3 to find 'y'

$y=6+2x$

$y=6+2(3)\\y=6+6\\y=12$

Roughly estimate the volume of a tennis ball in cubic cm by using 6 cm for diameter and 3 for pi. round the answer to the neares

galben [10]

The volume of ball is 113.04 cubic centimeter

Solution:

Given that we have to find the volume of tennis ball

Since the ball is of sphere shape, we can use the sphere formula

The volume of sphere is given by formula:

$V = \frac{4}{3} \times \pi \times r^3$

Where, "V" is the volume and "r" is the radius

Given that,

Diameter = 6 cm

Therefore,

$Radius = \frac{diameter}{2}\\\\Radius = \frac{6}{2}=3$

Substituting in formula, we get

$V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04$

Thus volume of ball is 113.04 cubic centimeter
