PLS HELP An auto travels at a constant rate of 30.0 km/hr for 0.100 hours then at 40.0 km/hr for 0.200 hours, and finally at 20.0 km/hr for 0.08333 hours. What is the total distance covered by the auto?

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.  

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
