Answer:
The most simplified form is 15√10
Step-by-step explanation:
1. Let's simplify the expression:
20√270 ÷ 4√3
20√9 * 30/ 4√3 (√270 = √9 * 30)
60 √30/ 4√3
(60 √3 * √10) / 4√3 (√30 = √3 * √10)
60/4 √10 ( We cancel √3 in the numerator and in the denominator)
15√10
The most simplified form is 15√10

Step-by-step explanation:
d. if he pays 120 cents per litre, how much does it cost to drive to and from work each week? Remember to divide your answer by 100 to convert the cost to dollars and cents.
Answer:
(b) 950 km
(c) 90 litres
(d) $108
Step-by-step explanation:
Henry lives 95 km from work.
Number of km from home to work = 95 km
Number of km from work to home = 95 km
One day = 95 + 95 = 190 km
Assuming he works 5 days a week.
1 day = 190 km
5 days = 190 x 5 = 950 km
Assuming he works 5 days a week.
1 day = 18 litres
5 days = 18 x 5 = 90 litres.
Assuming he works 5 days a week.
1 litre = 120 cents
90 litres = 120 x 90 = 10800 cents = $108
