Charlie is choosing between two exercise routines.
in routine #1, he does only running, burning
18.5
calories per minute.
in routine #2, he burns
22
calories walking. he then runs at a rate that burns
16.3
calories per minute.
for what amounts of time spent running will routine #1 burn at least as many calories as routine #2?
use
t
for the number of minutes spent running, and solve your inequality for
t
.

yes yes yes yes yes yes yes yes yes

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
