2 fractions between 3/5 and 4/5

Tasya [4]

Convert the fractions to decimals:

3/5=0.6
4/5=0.8

You have to find 2 fractions between these 2 numbers. You could pick anything.

7/10= 0.7 = less than 0.8 but greater than 0.6

75/100=0.75 = less than 0.8 but greater than 0.6

Hope this helps

Write a + - x or ÷ sign in each box to make the equation true <br><br> 7 18 45 3 2 = 139

irina [24]

I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:

7 * 18 + 45 / 3 - 2 = 139

Urgent!!!! not worried about a but i need b and #4

Oksi-84 [34.3K]

b) The surface area is 564.5. Picture below.

4. Three possibilities.

Formula for volume of a cylinder: πr^2h

Formula for volume of sphere: 4/3πr^3

If the radius of the sphere is 1 inch than the volume is: 4.18879 or 4.19 rounded.

I used substitution on this website https://www.omnicalculator.com/math/volume

Just plug in the 4.18879 at the cylinder volume and put in a random number in the radius or height whichever you want then it'll give you the one you left blank. You'll find three possibilities for the radius and height of 4.18879 volume.
