X = 0.045<br> Prove algebraically that x can be written as 1/22
blagie [28]
The least decimal place in 0.045 is found in the thousandths place. Thus, if expressed as a fraction, it would be 45/1000. Let's substitute this to the equation:

x = 45/1000
1000x = 45
(1000/45)x = 1
 
When you divide 1000 by 45, the quotient would be 22.2222222... This could be round to the nearest whole number which is 22. Then,

22x = 1
x = 1/22

I hope I was able to answer your question. Have a good day.

Using the net below, find the surface area
maw [93]

Answer:

Surface area = 90 cm²

Step-by-step explanation:

Given net of the rectangular prism shows the dimensions as,

Length = 5 cm

Width = 5 cm

Height = 2 cm

`Expression for the surface area of a rectangular prism = 2(lb + bh + hl)

Here, l = length

w = width

h = height

By substituting the values in the expression,

Surface area = 2(5×2 + 5×2 + 5×5)

                      = 2(10 + 10 + 25)

                      = 90 cm²

What is the solution of the equation w^2=4/9? show work.
astra-53 [7]

Answer:

w = ± \frac{2}{3}

Step-by-step explanation:

w² = \frac{4}{9} ( take square root of both sides )

w = ± \sqrt{\frac{4}{9} } = ± \frac{\sqrt{4} }{\sqrt{9} } = ± \frac{2}{3}

Then

w = - \frac{2}{3} or w = \frac{2}{3}
