27 treats per 3 minutes = 9 : 1
if the ratio is 9:1, multiply by 8, and you get
72 treats per 8 minutes
you're welcome!
Answer:
Step-by-step explanation:
Factorize 175 and 50
175 = 5 * 5 * 7
50 = 5 * 5 * 2
![\frac{\sqrt[3]{175}}{\sqrt[3]{}50}=\sqrt[3]{\frac{175}{50}}\\\\\\ =\sqrt[3]{\frac{5*5*7}{5*5*2}}\\\\\\=\sqrt[3]{\frac{7}{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B175%7D%7D%7B%5Csqrt%5B3%5D%7B%7D50%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B175%7D%7B50%7D%7D%5C%5C%5C%5C%5C%5C%20%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B5%2A5%2A7%7D%7B5%2A5%2A2%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B7%7D%7B2%7D%7D)
Answer:
We have a + b as;
2 + 3 = 5
Step-by-step explanation:
Here, we want go get the value of a and b
from the second equation, we can get an expression for b
We have this as;
7a - b = 11
Thus,
b = 7a - 11
Now, from here, we can substitute the value of b into the first equation
We have this as;
5a + 4(7a - 11) = 22
5a + 28a -44 = 22
33a = 22 + 44
33a = 66
a = 66/33
a = 2
Recall;
b = 7a - 11
substituting the value of a from above;
b = 7(2) - 11
b = 14 - 11
b = 3
First find the price of one pound.
11.94÷6=1.99
Once you find the price of 1 pound.
You multiply the price of one pound 8 times.
1.99×8=15.92
