Misaki cut some wood for a bookcase she is building.She needs to find how many 1/3 ft boards she can make from a 5 ft board.Expl

N76 [4]

Answer: There are 15 boards that she can make from a 5 ft board.

Step-by-step explanation:

Since we have given that

Length of a board = 5 ft

Length of board she can make from the above board is given by

$\frac{1}{3}\ ft$

We need to find the number of boards she can make from a 5 ft board.

According to question,

$\text{Number of boards}=\frac{5}{\frac{1}{3}}\\\\\text{Number of boards}=5\times 3\\\\\text{Number of boards}=15$

Hence, there are 15 boards that she can make from a 5 ft board.

What is the diameter of a sphere with volume of 7483

elena-14-01-66 [18.8K]

Answer:

The diameter of the sphere with the given volume is 24.268 units

Step-by-step explanation:

Volume of a sphere is given by the equation:

$V=4/3\pi r^3$

Plug in your volume and solve for r

$7483=4/3\pi r^3$

$7483(3/4)=\pi r^3$

$5612.25=\pi r^3$

$5612.25/\pi =r^3$

$1786.43=r^3$

$\sqrt[3]{1786.43}=r$

$r = 12.134$ units

$d = 2r$

$d = 2(12.134)$

$d = 24.268$ units

Add 5 ft 9 in and 10 ft 11 in

Stolb23 [73]

We know that 1 foot is 12 inches then, we change all quantities to inches to ease the calculations:
5 ft 9 in = 5(12) + 9 = 60 + 9 = 69 inches
10 ft 11 in = 10(12) + 11 = 120 + 11 = 131 inches
so we add:
<span>5 ft 9 in + 10 ft 11 in
= 69 inches + 131 inches
= 200 inches
if we want the result in foot we divide:
= 200/12
= 100/6 = 50/3
= 16 ft 8 in</span>
