Answer:
No multiplying both quantities in the ratio 60 : 36 by 1 would not give the answer .
But multiplying both quantities in the ratio 60 : 36 by 1/6 would solve it.
Step-by-step explanation:
Multiplying any number or ratio by 1 gives the same answer no matter what the expression or how much bigger the number is.This will not give the solution .
If it is multiplied with a fraction like 1/6 that would give the correct answer.
Multiplying it with 1/6 reduces the ratio and gives a better estimate.
A:B
60:36
60*1/6: 36*1/6
10: 6
Meaning that for a total of 16 there are 10 of category A and 6 of category B.
But if we do the same procedure with the answer is same which does not solve the question.
A:B
60:36
60*1: 36*1
60: 36

i took the cumulative exam
a) See attached diagram.
b) The slope can be obtained by the formula:
Now
The greatest increases were from 2012 till 2013 years and the least increases were from 2007 till 2008 years.
c) Using graphing calculator, the equation of the line (black line in the diagram) is
d) Since the slopes are different, this line is not straight. From the given data you can predict that the "best fit" is quadratic function.
e) In 2017, find
Answer:
![-7ab\sqrt[3]{3ab^2}](https://tex.z-dn.net/?f=-7ab%5Csqrt%5B3%5D%7B3ab%5E2%7D)
Step-by-step explanation:
Remove perfect cubes from under the radical and combine like terms.
![2ab\sqrt[3]{192ab^2}-5\sqrt[3]{81a^4b^5}=2ab\sqrt[3]{4^3\cdot 3ab^2}-5\sqrt[3]{(3ab)^3\cdot 3ab^2}\\\\=(8ab -15ab)\sqrt[3]{3ab^2}=\boxed{-7ab\sqrt[3]{3ab^2} }](https://tex.z-dn.net/?f=2ab%5Csqrt%5B3%5D%7B192ab%5E2%7D-5%5Csqrt%5B3%5D%7B81a%5E4b%5E5%7D%3D2ab%5Csqrt%5B3%5D%7B4%5E3%5Ccdot%203ab%5E2%7D-5%5Csqrt%5B3%5D%7B%283ab%29%5E3%5Ccdot%203ab%5E2%7D%5C%5C%5C%5C%3D%288ab%20-15ab%29%5Csqrt%5B3%5D%7B3ab%5E2%7D%3D%5Cboxed%7B-7ab%5Csqrt%5B3%5D%7B3ab%5E2%7D%20%7D)
Answer:
Step-by-step explanation:
Given that a store receives shipments of peaches. They want to sort them by weight.
The sorting pattern is as follows:
Peaches : Pound = 2:1 or 3.25:1 or 1:3.25
Given are i) 26 peaches to 13 lbs = 26:13=2:1 Hence goes to the first box
ii) 6 peaches to 19.5 lbs =6:19,5 = 1:3,25 lb. Hence goes to II box
iii) 13 peaches to 4 lbs: =13:4=3.25:1 Hence goes to II box
iv) 39 peaches to 12 lbs: =39:12=3.25:1 Hence goes to II box
v) 15 peaches to 7.5 lbs: =15:7.5=2:1 Hence goes to I box
i - I box
ii - II box
iii - II box
iv) - II box
v) - I box
