Answer:
2r
Step-by-step explanation:
You suppose that the radius of a larger circle = r
so diameter = r*2 = 2r
aint really sure tho
Answer:
skew
Step-by-step explanation:
Perpendicular lines must intersect. In fact, they intersect forming right angles.
Lines AC and RC are not in the same plane and do not intersect.
They are called "skew lines."
270 minutes = 4,5 hours = 4 hours and 30 minutes
60 minutes = 1 hour
63 miles per 270 minutes
x miles per 1 hour = 60 minutes
![\dfrac{63[miles]}{x[miles]} = \dfrac{270[minutes]}{60[minutes]}](https://tex.z-dn.net/?f=%5Cdfrac%7B63%5Bmiles%5D%7D%7Bx%5Bmiles%5D%7D%20%3D%20%5Cdfrac%7B270%5Bminutes%5D%7D%7B60%5Bminutes%5D%7D)


![x=14[miles]](https://tex.z-dn.net/?f=x%3D14%5Bmiles%5D)
His average speed is 14 miles per hour.

Answer:
The cost per pound of bananas is $0.84.
Step-by-step explanation:
The question asks to use the given information to set up a proportion and solve for the missing variable. In this case, we know that the cost of 2 1/4 (or 2.25) bananas is $1.89. Since they are asking for cost per pound, we can set up a ratio (fraction):

Since the cost of bananas is the same regardless of the number of pounds, we can set up a proportion to find the cost for just one (1) pound:
Where 'x' is the cost.
Using cross-multiplication and division we get: 2.25x = 1.89. Next, we use inverse operations to divide both sides by 2.25: 2.25x/2.25 = 1.89/2.25. Solve: x = 0.84 or $0.84 per pound.
