Step-by-step explanation: Multiplying fraction problems are easy. Let’s try one. 7/3 * 3/7. All you have to do is multiply the numerator by the numerator. And the denominator by the denominator. And you get the answer. Let’s try it. 7 time 3 is 21. And 3/7 is 21 also. So the answer is 21/21. Easy right?

Hope this helped! :D

To divide the mixed numbers, first rewrite each mixed number as an improper fraction. Then to divide the improper fractions, multiply the first fraction by the multiplicative inverse of the second fraction. The multiplicative inverse of 143 is 314

Answer:

C. II only

Step-by-step explanation:

Basically all you need do is plug these answers in and if the complete the inequality to make a true statement.

Yes i know no body want to do that but that whats need to be done lol.

once i plug 7 12/7+8 = 12.83

12.83>20

is incorrect

so we need continue

7*2.5+8>20

7*2.5= 17.5

17.5+8= 25.5

25.5>20

this a true statement

so we know 2.5 is an answer

now we need plug in -3

7*-3= -21

-21 +8 = -13

-13>20

this is incorrect

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

n a particular day, the wind added 2 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 2 miles p

goldfiish [28.3K]

Recall your d = rt, or distance = rate * time

notice, the time he took to cover 63 miles with the wind, is the same amount of time he took against it with 51 miles only, let's say, he took "t" hours long
and he was cycling at a rate of "r"

thus $\bf \begin{array}{lccclll}
&distance&rate&time\\
&-----&-----&-----\\
\textit{with the wind}&63&r+2&t\\
\textit{against the wind}&51&r-2&t
\end{array}\\\\
-----------------------------\\\\

\begin{cases}
63=(r+2)t\implies \cfrac{63}{r+2}=\boxed{t}\\\\
51=(r-2)t\\
----------\\
51=(r-2)\left( \boxed{\cfrac{63}{r+2}} \right)
\end{cases}$

solve for "r"
