A Pizza factory has come out with two kinds of pizzas.A square pizza of side 26 cm costs AED 80 and a circular pizza of diameter

DiKsa [7]

Answer:

Square pizza

Step-by-step explanation:

To obtain which pizza is the best buy:

Cost of square pizza :

AED 80

side length, s = 26cm

Area of square, A = s²

A = 26² = 676 cm²

1 AED of square pizza gives : 676 / 80 = 8.45 cm²

Cost of circular pizza :

AED 80

Radius, r = 28cm

Area of circle, A = πr²

A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²

1 AED of circular pizza gives : 616 / 80 = 7.7cm²

Hence, square pizza is the better buy ;

8.45cm² > 7.70 cm²

Detroit received 8 over 5 inches of snow in the morning. The city recorded of an 3 over 5inch of snow in the evening. What was t

xenn [34]

Answer:

11/5 inches

Step-by-step explanation:

total snowfall for the day = snowfall in morning + snowfall in evening

= 8 over 5 + 3 over 5 (all in inches)

= 8/5 + 3/5 (all in inches)

Since the denominators are the same (5), we can simply add the numerators up while keeping the denominator

(8/5 + 3/5) inches= (8+3)/5 inches = 11/5 inches = total snowfall for the day
