i) Plan A: 21/0,12 = 175 <min of calls>
Plan B: 15/0,14 ≈ 107 <min of calls>
=> 2 plans cost the same 107 min of calls
ii) The cost when 2 plans cost the same:
- Plan A: 107 × 0,12 = 12,84$ ≈ 13$
- Plan B: 107 × 0.14 ≈ 15$
Answer: i) 107 ii) A: 13$ B: 15$
Answer:
Head=3cm
Body=12cm
Tail=5cm
Step-by-step explanation:
H= head
B=body
T=tail
B =4h
T=2+h
Total length= 20cm
20cm = b+t+h
20cm= 4h+(2+h)+h
20cm= 6h+2
18cm=6h
3cm=h
Body 4(3)=12
Tail= 2+3= 5
The difference of a number and seven is x - 7. So twice that, would be:
2(x - 7)
Answer:
$10.80
Step-by-step explanation:
I'm assuming that the $15.10 includes the $9.70 she got from the old picture.
$15.10-$9.70=$5.40
That means half of her weekly allowance is $5.40
If half of her weekly allowance is $5.40, then her entire weekly allowance is $5.40*2 = $10.80
Answer:
-2.5
Step-by-step explanation:
The slope can be found by
m = (y2-y1)/(x2-x1)
= (3-18)/(4- -2)
= -15/(4+2)
=-15/6
= -5/2
-2.5
