Answer:
Estimate Tip = $4.50
Step-by-step explanation:
The bill to the nearest $10 is $30.00 : ( $ 30 ($32.43) $40, it is nearer to $30
Estimate Tip = Bill rounded to the nearest $10 × Tip %
Estimate Tip = $30 × 15%
Estimate Tip = $30 × .15 (15% change to a decimal is .15)
Estimate Tip = $4.50
Answer:
18cm
Step-by-step explanation:
Area of Trapezium = 1/2(a + b) h
Where:
A = 352cm^2
h = distance between parallel sides = 16cm
a = 25cm
b = ?
352 = 1/2 (25 + b) 16
352 = (25 + b) 8
352 = 200 + 8b
352 - 200 = 8b
152 = 8b
152/8 = b
19= b
→b = 19cm
The other parallel side is 19cm.
