Answer:
Delivery cost per minute = $0.3 per minute
Step-by-step explanation:
Given:
Cost of pizza = $12
Total amount pay by Ruby = $15
Time taken for delivery = 10 minutes
Find:
Delivery cost per minute
Computation:
Total amount of delivery = Total amount pay by Ruby - Cost of pizza
Total amount of delivery = 15 - 12
Total amount of delivery = $3
Delivery cost per minute = Total amount of delivery / Time taken for delivery
Delivery cost per minute = 3 / 10
Delivery cost per minute = $0.3 per minute
Answer:<u>3</u>
Step-by-step explanation:2+3/2=
3/2=1
2+1=3 Or 3.5
5 cm = 2km
Scale= 5 cm : 200000 cm
= 1 : 40000
a. 1 : 40000 = x : 500000
x = 12.5 cm
b.1 : 40000 = 2 : x
x = 80000 cm
x = 0.8 km
Answer:
Tank B
Step-by-step explanation:
Proportional relationships are relationships between two variables with equivalent ratios. For a proportional relationship, one variable is always a constant value times the other. A line is a proportional relationship if it starts from the origin, but if it does not start from the origin, it is not proportional.
From the two tanks, we can see that tank A have a y intercept whereas tank B starts from the origin. Therefore tank B shows a proportional relationship.
Answer:
a.2^(a+b+c)
b.2^(a+b+a-b)=2^(2a)or 4^a
c.2^(a+b+c)/2^(a+b)=2^(a+b+c-a-b)=2^c
