Shauna gets on a train 10 miles north of Washington, D. C. 45 minutes later she is 40 miles south of Washington, D. C. The train was moving at
a constant rate. Let Washington, D. C. be a location of zero, North be
positive, and South be negative. The equation for this situation is
1 = at + b, where is location in miles and tis time in minutes. Choose
the correct a and b for this equation.

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

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.
