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.

Answer:

(A) 2 3/10

(B) 1 7/15

Step-by-step explanation:

(A) Add the gallons he collected together to get the total amount of milk he started with: 4/5 + 6/8 + 3/4 = 2 3/10 gallons of milk.

(B) Take that number, 2 3/10, and subtract the amount of milk he has left to get the amount of milk he used. 2 3/10 - 5/6 = 1 7/15

Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?

Sophie [7]

Here are the numbers
4.3 , 5.5 , 6 $\frac{1}{6}$ , $\frac{15}{4}$ , 4 $\frac{3}{8}$
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
$6\frac{1}{6}$ <em />⇔6.1666---
$\frac{15}{4}$ ⇔3.75
$4 \frac{3}{8}$ ⇔4.375
Now to arrange them from least to the greatest
$\frac{15}{4}$ , 4.3 , $4 \frac{3}{8}$ , 5.5 , $6\frac{1}{6}$

Write ln 2x + 2x ln x -ln 3y as a single logarithm.

andreev551 [17]

Answer: option c.

Step-by-step explanation:

To solve this problem you must keep on mind the properties of logarithms:

$ln(b)-ln(a)=ln(\frac{b}{a})\\\\ln(b)+ln(a)=ln(ba)\\\\a*ln(b)=ln(b)^a$
