Second Man = (2 Hours * 1.3333 Hours) / (2 Hours - 1.3333 Hours)

Second Man = (2.6666666667 ) / (.666666667)

Second Man (when working alone) = 4 Hours

A can of tuna fish is a cylinder with a height of 1.75 inches and a diameter of 3 inches. If the can is half full, how many cubi

zlopas [31]

Answer: $6.185in^3$

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

$V_{cylinder}=\pi r^2h$

r is the radius of the cylinder and h is the height of the cylinder.

Given the diameter of 3 inches, calculate the radius of the cylinder with:

$r=\frac{d}{2}$ (Where d is the diameter)

$r=\frac{3in}{2}=1.5in$

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

$V_{can}=\pi (1.5)^2(1.75in)=12.37in^3$

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

$V_{tuna}=\frac{V_{can}}{2}\\\\V_{tuna}=\frac{12.37in^3}{2}\\\\V_{tuna}=6.185in^3$

What numeral in base 8 equivalent to 3325(denoting 332 base 5)

lakkis [162]

It can help to write each number in expanded form, where the digit is multiplied by a power of the base.

332 base 5 = 3*5^2 + 3*5^1 +2*5^0 = 75 +15 +2 = 92

In base 8, this is
92 = 64 + 24 + 4 = 1*8^2 + 3*8^1 + 4*8^0 = 134 base 8

_____
The conversion of an integer to base b is often done by finding the remainder when dividing by b.
92/8 = 11 remainder 4
11/8 = 1 remainder 3
1/8 = 0 remainder 1

The digits of the converted number (right to left) are the remainders at each step. Here: 92 = 134 (base 8).
