What is 2 3/8 * 1/3. Estimate the product

2 3/8 x 1/3 I believe? First you need to change 2 into a 16 then add that into 3 which is 19/8. You multiply across with 1/3 like with numerator with numerator and denominator with denominator. That then equals:19/24. You can't estimate it because 19 is a prime number.

find an expression for the area of a rectangle of sides 2x+3 and x-1 given that the perimeter is 28cm what is the value of x
Ierofanga [76]

Answer:

4cm

Step-by-step explanation:

Given data

L=(2x+3)

W=(x-1)

P=28cm

A= L*W

A= (2x+3)*(x-1)

open bracket

A= 2x^2-2x+3x-3

collect like terms

A= 2x^2+x-3

P= 2L+2W

P= 2*(2x+3)+2(x-1)

P= 4x+6+2x-2

collect like terms

P= 6x-4

but p= 28

28= 6x-4

28-4= 6x

24= 6x

x= 24/6

x= 4cm

Hence x= 4cm

If a cube has a side length of 4 1/2 cm, what is one way to write the volume of the cube?
atroni [7]

For this case we have that by definition, the volume of a cube is given by: V = s ^ 3

Where,

  • <em>s: Side of the cube </em>

We have that the cube side is given by:

s = 4 \frac {1} {2} cm

Therefore, replacing values we have:

V = (4 \frac {1} {2}) ^ 3 cm ^ 3

Answer:

One way to write the volume of the cube is:

V = (4 \frac {1} {2}) ^ 3 cm ^ 3
