Answer:

The answer is

5 \sqrt{2}

Step-by-step explanation:

By using Pythagoras

Then

{y}^{2}   +  {y}^{2}  =  {10}^{2}  \\ 2 {y}^{2}  = 100  \\  {y}^{2}  = 50 \\ y =  \sqrt{50}  =  \sqrt{2 \times 25}  = 5 \sqrt{2}

Determine whether each statement is sometimes, always, or never true. If the scale factor of two similar solids is a:b, then the
Nady [450]

Answer:

never

Step-by-step explanation:

let k be the scale ratio of two bodies then according to the question

k = a/b  -- (1)

let Sa be the surface area of body A and Sb be the surface area of body B , then

according to the relation of scale factor and surface areas

k^{2}  Sa = Sb

from the above equation ,

Sa/Sb = 1/k^{2}

as k = a/b  from (1)

thereforeSa/Sb=1/(a/b)^{2} \\Sa/Sb = b^{2} /a^{2}

hence the ratio of their surface area is b^{2} /a^{2}
