Answer:
Step-by-step explanation:
Number of cows increased=60
Old quality of milk consumed=12.8litres
New Increase in milk consumed=15litres
Therefore the number of cows in the farm if the quality of milk is 1340litres=y
Therefore, 1cow =15litres
y cows= 1340litres
Crossmultiply:
15litres×ycows=1340litres
Make y the subject of formula
y= 1340÷15
y=89.33cows
Therefore,the number of cows on the farm if farmer gets 1340litres of milk would be 89cows.
Answer:
The answer is B. m∠ POS + m∠ POR = 180
step-by-step explanation:
Because if you already know that m∠POQ equals 90 because it is a right angle
Then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45
now you have the measurement for the two acute angles 45
which makes m∠POS = 45 and m∠QOR =45
NOW YOU HAVE TO ADD 90 AND 45 AND 45 ALL TOGETHER THEN YOU WILL HAVE 180

Rearranging Formula. This unit covers rearranging formulae. The manipulation of algebraic expressions is an important ... Changing the subject of a formula .
Step-by-step explanation:
Explanation:
The equation for this problem can be modeled in y = mx + b form.
m represents the rate of change and b represents the initial value or constant.
y = 10x + 20
x represents the number of hours he spent delivering newspapers
y is his total money after whatever number of hours he worked
The rate is 10, because it determines how much money he earns for each hour.
The y-intercept is 20, representing the starting amount of money in his bank account.
