Aflexible pavement is known to have a structural number of 4.0 and a soil resilient modulus of 13,000 psi. if a pavement structure is to be designed for a life of 15 years, a reliability of 95% and an overall standard deviation of 0.3, how many passes of a design vehicle with a 18,000 lb single axle and a 34,000 lb tandem axle can be driven on the pavement per day? the pavement's initial psi is 4.2 with a tsi of 2.5.

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.

step-by-step explanation: 2

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50

step-by-step explanation:

add 8+12 to get a simplified answer of 12r-20
