At the grocery store, an 8-inch cherry pie costs $4.39 and a similar 10-inch cherry pie cost $6.15. which is the better deal?
ValentinkaMS [17]
For the 8 inch pie you are paying about 55 cents per inch 
for the 10 inch pie you are paying about 61 cents per inch 
so the 8 inch pie is a better deal 

hope this helped 
oh and to get those numbers divide 4.39 by 8 and 6.15 by 10

Billy likes to go cycling.
Agata [3.3K]

Answer:

560 metres

Step-by-step explanation:

80 cm in metres is 0.8 metres.

After 1 revolution any point on the wheel will be back to the original position before moving. 0.8 times 2, which gives us 1.6 metres. In 1 revolution the bike travels 1.6 metres.

Now 1.6 metres times 350 gives us 560.

So the answer is 560 metres.

The base of a trinagle is increased by 20% and it’s height is increased by 30%. By what percent is the area of the triangle incr
Molodets [167]

Lets say the base is x and the height is y. The new base would be 1.2x and the new height would be 1.3y

Area of a triangle is base times height divided by 2:

1.2x*1.3y/2 = (1.2*1.3 + x*y)/2 = 1.56xy/2 = 0.78xy = 78% of xy

But a normal area would be 50% of xy

78% - 50% = 38%

ANSWER: 38% increase
