adell [148]

Answer:

8\pi miles or 25.133 miles

Jeff should purchase 25 , 2 ounce box and it will cost him $27.5 .

Ounce is defined as 1/16 part of a pound.

It is given that

price of a 2-ounce box is $1.10,

a 16-ounce box is $8.98

a 32-ounce box is $17.98.

As Jeff wants to purchase total 48 ounce chocolates , the box which is more cheaper has to be determined  

The price of 1 ounce in a 2 ounce box is $1.1 /2 = $ 0.55

The price of 1 ounce in a 16 ounce box is $8.98 /16 = $ 0.56

The price of 1 ounce in a 32 ounce box is $17.98 /32 = $ 0.56

Therefore Jeff should purchase 25 , 2 ounce box and it will cost him $27.5 .

Which has the greater capscity 7/8 of a cup. Or 2/8 of a gallon
dalvyx [7]
Well, there are 8oz in a cup, so in 7/8 of a cup there are 7/8 * 8 ounces or 7oz then.

now, a gallon has 128oz total, so  2/8 of a gallon will then be (2/8) * 128, or 32oz.

so, fairly sure you can tell who has greater capacity.

If a 5 meter long metal bar has 40 kg mass then what is the mass of a metal bar 3 meters long
hjlf

24 kg

Step-by-step explanation:

You start by calculating the linear mass density of the rod:

d = m/L = (40 kg)/(5 m) = 8 kg/m

So for a 3-m long bar, the mass can be calculated as follows:

m = d×L = (8 kg/m)(3 m) = 24 kg
