Answer:
56.3 in²
Step-by-step explanation:
Given 2 similar figures with linear ratio = a : b, then
area ratio = a² : b²
Here linear ratio = 4 : 3, thus
area ratio = 4² : 3² = 16 : 9
Let x be the surface area of the smaller can then by proportion
= ( cross- multiply )
16x = 900 ( divide both sides by 16 )
x ≈ 56.3 in² ( to the nearest tenth )
1. all real numbers
2. y > 0
3. approaches y = 0
not really what unit test or topic is that ?
-42.66666...
-64 * 2/3 is -42.66666...
well, according to the calculator.
(x+4)
