Answer:
c) they are screw lines
Step-by-step explanation:
A and B will intersect but never create a 90 degree angle. It comes at and angle smaller
Joint variation equation is a situation when the final value varies by two or more variables
Equation 1
A = s²
Here we have only one variable, 's', and the value of Area will only vary when s varies.
Equation 2
A = πr²
Here the only variable is 'r', which is the radius of a circle. The value of Area, A, varies as radius varies. π is a constant.
Equation 3
A = l×w
Here we have to variables, the 'l' and the 'w'.
We can say that the value of Area, A, will vary jointly as l and w vary
The correct answer is option a)
X= a number
29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4
CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21
ANSWER: The number is 4.
Hope this helps! :)
Let the number of smaller pages be x and that of larger pages be (16-x)
Total number of words in the smaller pages will be:
x×1200=1200x
Total number of words in the large pages will be:
1500(16-x)=24000-1500x
the total number of words will be:
24000-1500x+1200x=21000
-300x=-3000
x=-3000/-300
x=10
the number of small pages was 10 and the number of large pages was 16-10=6 pages.
