60 marbles
11 purple
20 green
So red =60-11-20=29
I ain’t sure tho
Answer:
2cm of Rainfall
Step-by-step explanation:
When the no. of mosquitoes is the highest the slope of graph will be zero
so if we differentiate this function and equate to zero we can find the rainfall amount that gives maximum number of mosquitoes in centimetres.
m(x)= -x²+4x
differentiate
d(x)/d(m(x))= -2x+4
equate to zero
-2x+4=0
2x=4
x=2
answer: 2 cm of rain
Jonah is incorrect because 3/4 and 2/5 don't have a common denominator of 9.Jonah probably added 4 and 5 together but that isn't the common denominator. You can check by doing this:
4,8,12,16,20,24,28,32,36,40
5,10,15,20,25,30,35,40,45,50
As you can tell 3/4 and 2/5 common denominator could be 20, 40 and many more but the more reasonable denominator would be 20.
3 times 5 = 15 2 times 4= 8
- -
4 times 5 = 20 5 rimes 4=20
You have to multiply the numerator the same number that you multiplied it with the denominator to get 20
This is a plain and simple answer. No distributive property here!
68 ÷ 4 = 17
