Answer:
$31.86
Step-by-step explanation:
You can use a proportion here.
37.05 = 100%
x = 86% (100%-14% which is a delivery fee)
x = (37.05*86)/100
x = 3186.3/100
x = 31.86
The cost of their dinner before the delivery fee was $31.86.
I hope that I helped :)
Answer:
The ladder has 20 steps
Step-by-step explanation:
10 is the direct middle if you go down 4 that is 6, if you go back up 7 you get 13 and if you go back down 13 and you are on the first step 13-13 is 0, so the ladder has 20 steps.
I would say the correct answer choice would be amswer choice D
Radius = 5 cm
Height = 8 cm
Volume = πr²h
Volume = π(5 cm)² × 8 cm
Volume = π × 25 cm² × 8 cm
Volume = 200π cm³
Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
