Step-by-step explanation:
1. If Paolo pays $19.50 and Raoul $22.35 we need to rest values:
$22.35 - $19.50 = $2.85 Saves Paolo
2. Each bow requires 34 yards of ribbon, if she does 50 she need:
34 yards x 50 bows = she needs 1700 yards of ribbon, having saying this, if you have only the 4 options described, she will need to purchase the smaller amount of ribbon. (Letter A) because she’ll had more than enough to make the 50 ribbons and is the less amount.
3. If the basketball player is 167.64 cm tall, and 1 inch is equal to 2.54 cm the heigh of the player:
167.64 cm / 2.54 = 66 inches tall
4. On this exercise you do not mentioned any unit of measurement, yet we are going to call them u (34 u of paint). If she painted 3 walls with 34 u of paint:
34u / 3 walls = 11.33 u of pain on each wall
5. If the water level changed in year 1 -1110 in and in year 2 -125:
-1110 in -125 in = -1235 in (in total
)
