it is already a whole number dude
Answer:
9a) 6 miles
9b) 12:20
Step-by-step explanation:
for first question, use the distance formula: distance = rate · time
d = 2 x 3
d = 6 miles
for second question, she began walking home at 11:05 and it took 1 hour, 15 minutes (15 minutes is 1/4 of 60 minutes)
11:05 + 1 hour = 12:05
12:05 + 15 minutes = 12:20

Answer:
528 cm²
Step-by-step explanation:
The surface area of this prism comprises:
- 2 congruent triangles (the bases of the prism)
- 2 congruent rectangles (rectangle 1 and 2) - since the triangle has 2 sides of equal length
- 1 rectangle (rectangle 3)
Area of a triangle = 1/2 × base × height
= 1/2 × 16 × 6
= 48 cm²
Area of rectangle 1 / 2 = width × length
= 10 × 12
= 120 cm²
Area of rectangle 3 = width × length
= 16 × 12
= 192 cm²
Total Surface Area = 2 triangles + 2 rectangles + rectangle 3
= (2 × 48) + (2 × 120) + 192
= 96 + 240 + 192
= 528 cm²
