Answer:
7 cm
Step-by-step explanation:
SA = 208 cm^2
SA= 2*a*b + 2*a*c + 2*b*c
where:
a= first dimension = 2 cm
b= second dimension = 10 cm
c= third dimension
so we have:
208= 2*2*10 + 2*2*c + 2*10*c
208= 40 + 4c + 20c
208-40= 24c
168=24c
c =168/24
c = 7cm = third dimension
The given expression is
This can be simplified using the radical properties as below
Now using exponent properties we can write
Scale factors of negative numbers are contractions
scale factors of numbers greater then 1 are expansions
scale factors of numbers greater then 0 but less then 1 are contractions
Answer:
1. 9/25 units^2
2. s = 1/4 unit
3. = 8/27 units^3
4. s = 3/4 unit
Step-by-step explanation:
1. The area of a square is A=s^2
A = (3/5)^2
= (3/5) *(3/5)
= 9/25 units^2
2. The area of a square is A=s^2
1/16 = s^2
Take the square root of each side
sqrt(1/16) = sqrt(s^2)
1/4 = s
s = 1/4 unit
3. The volume of a cube is V = s^3
V = (2/3)^3
= (2/3) (2/3) (2/3)
= 8/27 units^3
4.The volume of a cube is V = s^3
27/64 = s^3
Take the cube root of each side
(27/64)^(1/3) = (s^3)^(1/3)
3/4 = s
s = 3/4 unit
