Answer:
80 cm²
Step-by-step explanation:
Given 2 similar figures with sides in the ratio a : b , then
ratio of areas = a² : b²
Here ratio of sides = 7 : 14 = 1 : 2
ratio of areas = 1² : 2² = 1 : 4
Thus area of B is 4 times area of A
area of B = 4 × 20 = 80 cm²
Answer:
part A: 10.52
part B: 67.33
Step-by-step explanation:
part a:52.60 x 0.20=10.52
part b:52.60 x 0.08=4.2080
4.2080 about equal to 4.21
52.60 x 0.20=10.52
the amount of the bill before tax = 52.60
52.60+4.21+10.52=67.33
Answer:
8.57 miles
Step-by-step explanation:
It is provided in the question that,
<em>Janice drove 360 miles in 6 hours.</em>
<em>Formula to calculate speed = distance / time</em>
Speed at which Janice drove = 360 / 6
= 60 miles/hours
<em>To find, </em>
<em>distance Janice will cover in 7 hours </em>
Distance = speed * time
Distance = 60miles/hour * 7 hours
Distance = 8.57 miles
So the distance Janice travel i 7 hours at 60miles/hr is 8.75miles
