This says:

The volume of a cube is 125cm^3

How many times the volume will increase if we duplicate the lenght of the side?

If L is the lenght of the side, we have that the volume of the cube is:

V = L^3

If we duplicate the lenght of the side, the new volume is:

V = (2*L)^3 = 8*L^3

So we can see that the volume of the new cube is 8 times the volume of the previous cube.

Now,  we can do the math, for our original cube we have:

L^3 = 125cm^3

L = 5cm

the new cube has L' = 2*L = 10cm

The volume of this cube is:

V' = L'^3 = 10cm^3 = 1000cm^3

the ratio V'/V is:

1000cm^3/125cm^3 = 8

Answer:

The volume of the prism is 27 cubic inches.

Step-by-step explanation:

In order to calculate the volume of the given prism, we need to apply the correct formula. The volume of the wedge prism is given by the following formula:

[tex]Volume = \frac{1}{2}*b*h*l[/tex]

Applying the data from the problem on the equation above, we have:

[tex]Volume = \frac{1}{2}*6*4.5*2\\Volume = 6*4.5\\Volume = 27[/tex]

The volume of the prism is 27 cubic inches.

Answer: I agree with Sita.

Step-by-step explanation:

An infinite number is a very big number which is impossible to physically achieve. I agree with Sita because when Rita is forming equations on and on to an extent of not knowing when to stop. That is when she can say to infinite. And I don't think this is possible.

Answer:

0.019

Step-by-step explanation:

Here, we want to calculate the probability that 4 people selected at random have green eyes.

The probability of having green eyes = 0.37

Now, we are selecting 4 people and we want to calculate the probability that all have green eyes

That would be;

0.37 * 0.37 * 0.37 * 0.37 = 0.01874161 which is 0.019 to 3 decimal places

Answer:

Step-by-step explanation:

Answer:

The answer would be 2/3.

Step-by-step explanation:

There are 6 faces on a dice 3 of which are odd which would be 1/2. Then there is one face on a dice that has 3 dots on it which would 1/6. So 1/2+1/6= 4/6 which simplifies to 2/3.

Answer:

(X+2)power of 2 + (y + 3)power of 2 = 9    

Step-by-step explanation:

Answer:

[tex] (x + 2)^2 + (y + 3)^2 = 9[/tex]

Step-by-step explanation:

Center = (-2, - 3) = (h, k)

Radius (r) = 3

Equation of circle in centre radius form is given as:

[tex] (x - h) ^2 + (y - k) ^2 = r^2 \\

\therefore \{x - (-2)\}^2 + \{y - (-3)\}^2 = 3^2 \\

\purple {\boxed {\bold {\therefore(x + 2)^2 + (y + 3)^2 = 9}}} [/tex]

Answer:

-20

Answer:

YES

Step-by-step explanation:

57+45=102.

The triangle needs to have angles that add up to 180 so..

180-102=78

and that is the other degree instead of 45 on the other triangle

Hey there!

Answer:

x = 73°

Step-by-step explanation:

a whole circle = 360°

so x + 50° + 91° + 2x = 360°

x+ 2x = 360°- 91° - 50°

3x = 219°

x = 219° ÷ 3

x = 73°

72 Pencils

24 calculators

72/24  = 3/1

for Every one calculator 3 Pencils need to be used

Greatest number of Package = 24 as 24 Calculators are there

number of pencils in each package = 3   ( 72/24 = 3)

Answer:

3 pencils will be in each package

Step-by-step explanation:

You divide 727272 by 242424 to get 3

Answer:

k=3.5

Step-by-step explanation:

1. Understand which lines are similar in the triangles. In this case, because we can see that the line YX is a hypotenuse and line QP is a hypotenuse we can see that YX and QP are similar. Therefore, we can see that YZ is similar to QR and ZX is similar to RP.

2. For finding an unknown side for similar triangles, you use the equation [tex]\frac{x}{y} =\frac{a}{b\\}[/tex] where x(also known as k) is the unknown side (QR), y is the similar side to the unknown(YZ), a is a known side(Let's use RP), and b is the similar side to the known side (In this cause, it would be ZX).

2. Plugging all the sides into the equation, it should turn into [tex]\frac{x}{10.5} =\frac{5.5}{16.5}[/tex].

3.After cross-multiply, you should get 16.5x=10.5×5.5 or 16.5x=57.75.

4. Then by dividing 16.5 on both sides, you should get 3.5

Answer:

Given:

a + b = 9

=> a = 9 - b

Given:

a x b = 18

=> (9 - b) x b = 18

=> 9b - b^2 = 18

=> b^2 - 9b + 18 = 0

=> (b - 3)(b - 6) = 0

=> b = 3 => a = 6

=> b = 6 => a = 3

Answer:

1247.03

Step-by-step explanation:

if £1=$1.35

?=$125(crisscross them to get an answer.)

$125×£1÷$1.35=£92.59

if £1=$1.35

?=$6(crisscross to get an answer.)

$6×£1÷$1.35=£4.44

so you add them all up

£1150+£4.44+£92.59= £1247.03

Answer:

the volume of the sphere is

[tex]33.51 in^{3}[/tex]

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, sphere and cube.

Given data

Volume of cube v =   64 cubic inches

since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,

we know that volume of cube is expressed as

[tex]v= l*b*h[/tex]

[tex]v=l^{3}[/tex]

[tex]64= l^{3}[/tex]

[tex]l= \sqrt[3]{64}[/tex]

[tex]l= 4 in[/tex]

also diameter d=length l

Diameter d=  [tex]4in[/tex]

Radius r =  [tex]\frac{d}{2}[/tex]= [tex]\frac{4}{2}[/tex]= [tex]{2 in}[/tex]

Height h=[tex]4in[/tex]

we know that the volume of a sphere is given by

[tex]v= \frac{4}{3} \pi r^{3}[/tex]

substituting into the formula we have

[tex]v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}[/tex]

Answer:

x = 64

Step-by-step explanation:

90 + x + 26 = 180

116 + x = 180

x = 180 - 116

x = 64

Answer:

x=64

Step-by-step explanation:

x and 26 are complementary, which means they add to 90 degrees.

x+26=90

We want to find x, so we have to get x by itself. 26 is being added on to x. To undo this, subtract 26 from both sides, because subtraction is the opposite of addition.

x+26-26=90-26

x=90-26

x=64

So, x is 64 degrees
