4.John purchased a roll of cloth 2m long for $205.00 . He resold the cloth in lengths of 250 mm for $40.00 per length. Calculate profit he made.​

profit $115.00

Step-by-step explanation:

1 m = 1000mm

2 m = 1000 × 2 = 2000mm

2000 ÷ 250 = 8

he sold 8 pieces of cloth

40 × 8 = $320.00

profit

320 - 205 = $115.00

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.
