22(w+2)=77 iready help me please

w = 1.5

Step-by-step explanation:

22(w + 2) = 77 ← distribute parenthesis on left side

22w + 44 = 77 ( subtract 44 from both sides )

22w = 33 ( divide both sides by 22 )

w = = = 1.5

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
