Answer:
The fraction 58/60 is equal to 29/30 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (29/30) by any interger number, ie, multiply by 2, 3, 10, 30... 58/60 is equivalent to 29/30 because 29 x 2 = 58 and 30 x 2 = 60

Answer:
Step-by-step explanation:
Let the volumes of both the spheres be
and their radii be
respectively.
(given)
![\implies\huge \frac{r_1}{r_2}= \frac{13}{9}.....(1)](https://tex.z-dn.net/?f=%20%5Cimplies%5Chuge%20%5Cfrac%7Br_1%7D%7Br_2%7D%3D%20%5Cfrac%7B13%7D%7B9%7D.....%281%29)
From equations (1) & (2), we have:
Thus, the ratio of the volumes of two spheres would be 2197 : 729.
Well... in the first one you have a probability of 72 percent. In the secondd box you have a probability of 34 percent.
If you're asking us to solve for Z...
z² + 11z = -21/4
4z² + 44z + 21 = 0
Enter... *drumroll* the quadratic equation!
![z = \frac{-b +- \sqrt{b^{2}-4ac}}{2a}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B-b%20%2B-%20%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%7D%7B2a%7D%20)
(that's a plus or minus, sorry)
![z = \frac{-44 +- \sqrt{44^{2}-4(4)(21)}}{2(4)}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B-44%20%2B-%20%5Csqrt%7B44%5E%7B2%7D-4%284%29%2821%29%7D%7D%7B2%284%29%7D%20)
x = -0.5 or -10.5
Does this help? Is it too complicated? Do you have any questions?
