From given, we have, The side of a cubical watermelon is equal to the diameter of a spherical watermelon. The volume of a cube = a³ The volume of a sphere = 4/3 πr² Let us consider the radius of the sphere is "x" Then, we get The volume of a cube = (2x)³ = 8x³ The volume of a sphere = 4/3 πx² let us take, x = 2 cm Then, we have, The volume of a cube = 8x³ = 8×2³ = 64 The volume of a sphere = 4/3 πx² = 4/3 × 3.14 × 2² = 16.74 Thus the cubical watermelon would occupy more space than the other

Yogita Ingle 5 years, 8 months ago

0.4x + 0.3y=1.7...(1)
0.7x - 0.2y= 0.8...(2)
multiplying eq 1 by 2 & eq 2 by 3, we get
0.8x + 0.6y = 3.4..(3)
2.1x - 0.6y = 2.4..(4) now adding eq 3&4
2.9x= 5.8
x=5.8/2.9
x=2
putting the value of x in eq (1)
0.4×2 + 0.3y=1.7
0.3y= 1.7-0.8
y=0.9/0.3
y=3
Answer x=2 y=3

Draw the graph of the linear equation 2x + 3y =12. At what points the graph of the equation cuts the x-axis and y-axis

Posted by Anshu Singh Dudi 5 years, 8 months ago

CBSE > Class 09 > Mathematics

Yogita Ingle 5 years, 8 months ago

The pointy where graph cut x-axis and y-axis are x-intercept and y-intercept.

The x-intercept is when y=0,

2x+3(0)=12

2x=12

{tex}x=\frac{12}{2}{/tex}

x=6

So, Graph cut x-axis at (6,0).

The y-intercept is when x=0,

2(0)+3y=12

3y=12

{tex}y=\frac{12}{3}{/tex}

y=4
So, Graph cut y-axis at (0,4).

Refer the attached figure for graph.

Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

i) p(x) = 5x - 4x² + 3

On putting x=0 ,

p(0) = 5(0) - 4(0)² + 3

= 0 - 0 +3=3
= 3

ii) (x) = 5x - 4x² + 3

On putting x= -1,

p(-1) = 5(-1) - 4(-1)²+ 3

= -5 - 4(1) + 3

= -5-4+3= -9+3= -6

= -6
iii) p(x) = 5x - 4x² + 3

On putting x=2

p(2) = 5(2) - 4(2)² + 3

= 10 – 16 + 3 = -6+3

= -3

Yes, zero (0) is a rational number.It can be written in the form of p/q, where q is not equal to Zero. For ex.- 0/6, 0/4 , 0/1 ,etc. When zero is divided by any number the answer is zero. Therefore 0/6=0, and so on.
