Laura is training to run a race. she keeps track of the number of miles she runs. she has been training for 11 weeks, and she has run a total of 121 miles. at what rate has she been running, in miles per week?

11 weeks — 121 miles

1 week — x miles

x = 121/11= 11 (miles per one week)

11.

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.

b). 4320 have a nice day
