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:
a(n) = -3 - 2(n-1)
Step-by-step explanation:
The most general formula for the nth term of an arithmetic sequence (such as this sequence is) is
a(n) = a(1) + c(n-1), where c is the common difference.
Here a(1) = -3 and c = -2.
Thus,
a(n) = -3 - 2(n-1).
Twelve runners because if you take three-fourths times four you will get twelve-sixteenths. and each runner runs one-sixteenth so it is twelve.
Answer:
The equation of the line passing through the point (1,-4) and making an angle of 135º will be:
Step-by-step explanation:
Given the point (1, -4)
Given that the line makes an angle of 135º.
so
Slope = m = tan 135º = -1
Using the point-slope form of the line equation
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -1 and the point (1,-4)
subtract 4 from both sides
simplify
Therefore, the equation of the line passing through the point (1,-4) and making an angle of 135º will be:
First, turn 70% into a decimal by dividing 70 by 100.
70% ⇒ 0.70
Multiply 120 by 0.70.
120 × 0.70 = 84
Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.
120 - 84 = 36
<h2>Answer:</h2>
<u>36 seventh grade students are not involved in extracurricular activities.</u>
