Answer:
A. you need 2 1/2 ounces
B. you need 73,9 milliliters
Step-by-step explanation:
A
We have the ratio 1/2 ounces per gallon
And the mop bucket holds 5 gallons
Then we need to multiply 1/2*5
we got 2 1/2 ounces of desifectant per 5 gallons
B
1 ounces equal 29,57 milliliters
if we have 2 1/2 ounces then we multiply 2,5 *29,57
the answer is 73,9 milliliters
You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.
For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.
Now graph those equations.
Here the two samples should be comparable .
The total number of cows in the farm = 200
the total number of cows giving milk = 150
the total number of cows in corral = 20
Suppose total number of cows giving milk in corral = x
The ratio of the total number of cows present to the total number of cows giving milk should be same in farm and corral
so : 200 = 20
------- -------
150 x
now we do cross multiplication :
200 x = 150* 20
200x = 3000
x= 3000/200
x= 15
SO we expect 15 cows in corral should be giving milk .
Answer : 15
