A plane traveling with the wind travels 900 miles in 5 hours. The return trip is against the wind and takes 9 hours. Find the rate of the plane in still air and the rate of the wind. plane in still air mph?
wind speed mph?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

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.
