Answer:
B .62.5 m
Step-by-step explanation:
convert Kmh-1 in to ms-1
30 Kmh-1 = (30×1000) ÷3600 = 8.3ms-1
60 Kmh-1 = (60×1000) ÷3600 = 16.6 ms-1
acceleration = (16.6 - 8.3) ÷ 5 = 1.66 ms-2
V^2 = U^2 +2aS
(16.6)^2 = (8.3)^2 + 2×1.66 ×S
S = 62.5 m
The length of the missing sides of triangles A and B are 9.43 cm and 12.04 cm respectively.
<h3>Pythagoras theorem</h3>
Triangle A:
- Height = 8cm
- Base = 5cm
- Hypotenuse = x cm
Hypotenuse² = height ² + base²
x² = 8² + 5²
= 64 + 25
x² = 89
x = √89
x = 9.43 cm
Triangle B:
- Height = 12cm
- Base = x cm
- Hypotenuse = 17 cm
Hypotenuse² = height ² + base²
17² = 12² + x²
17² - 12² = x²
289 - 144 = x²
145 = x²
x = √145
x = 12.04 cm

Answer: 11 shelves
Step-by-step explanation:
Total number of juice boxes:
= 32 + 56
= 88 boxes
Each cupholder holds 8 boxes. Number of shelves needed is:
= Number of boxes / Boxes per holder
= 88 boxes / 8 boxes per holder
= 11 shelves
