A.)44
The total number will equal 180. All right angles are 90. 180-90-46 equal 44
Answer:
3/2
Step-by-step explanation:
3/4÷1/2=3/2
Consider the complete question is "Ben, Cam, and Justin are lumberjacks. The number of trees they chop down is given by b+2c+3j, where b is the number of hours Ben spends chopping, c is the number of hours Cam spends chopping, and j is the number of hours Justin spends chopping. How many trees do they chop down after Ben spends 8 hours chopping, Cam spends 3 hours chopping, and Justin spends 4 hours chopping?"
Given:
Total number of trees chopped by them = 
b = number of hours Ben spends chopping = 8
c = number of hours Cam spends chopping = 3
j = number of hours Justin spends chopping = 4
To find:
The numerical value of total number of trees chopped by them.
Solution:
Total number of trees chopped by them = 
Put
and
in the given expression.



Therefore, total number of trees chopped by them is 26.
Answer:
90% Solution
Step-by-step explanation:
5% of 90 + 90% of x = 75% of (90 + x)
5×90/100 + 90x/100 = 75×90/100 + 75x/100
Or 90x/100 - 75x/100 = 75×90/100 - 5×90/100
Or 15x/100 = 90×70/100
Or X = 420ml
You Will Need ML Of The 90% Solution To Obtain ML Of The Desired 75% Solution.
