(6-4)/5x100=
First take mind in PEMDAS or do the equation in the order of parenthesis, exponents, multiplication, division, addition, subtraction.
So first parenthesis or (6-4)=2
2/5x100
There are no exponents, so now we must do the multiplication or 5x100=500
2/500
now we do division or 2/500=0.004
There-forth the answer is actually 0.004 and not "40"

643.72
Step-by-step explanation:
Answer:
Equation is x^2/576+y^2/400=1
Vertical height is 19.84inches
Step-by-step explanation:
The equation of an ellipse with horizontal major axis with center at (0,0) is x^2/a^2+y^2/b^2=1
From the question, a=24 and b=20
Therefore the equation of the ellipse = x^2/24^2+y^2/20^2=1
= x^2/576+y^2/400=1
To calculate vertical height y:
y^2/400=1- x^2/576
y^2=(1- x^2/576)*400
y=20√(1- x^2/576)
At x=3 inches from the centre
y=20√1-0.0156
y=20*0.9922
y=19.84inches
Answer:
6.28
Step-by-step explanation:
2 x 3.14
Answer:
Down the left-hand column, the pattern is counting by 5's. Therefore, 5, 10, 15, 20, 25. Down the right-hand column, the pattern is counting by 4's. Therefore, 4, 8, 12, 16, 20. Thus, the ratios are:
5:4
10:8
15:12
20:16
25:20
In other words, the first line (5:4) is the base ratio. The second line multiplies the original values by 2, the third line by 3, the fourth line by 4, and the fifth line by 5.
