Ryan is biking at 31.8 miles per hour. what is his speed in feet per second? round to nearest tenth

46.6 ft/sec (to the nearest tenth)

Step-by-step explanation:

There's a common identity useful here:  60 mph = 88 ft/sec.

Mult. 31.8 mph by the conversion factor (88 ft/sec) / (60 mph), obtaining:

46.64 ft/sec.

2.83941151 would be the answer you're looking for! : )

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.
