Answer:
Step-by-step explanation:
Actually, you can't. You could multiply the numerator and denominator of each 4/3 and 3/3 by 5, obtaining:
5(4) 5(3)
------ and --------
5(3) 5(3)
but this result has little practical value. 4/3 and 3/3 could be combined immediately, obtaining 7/3, if that's what you want to do, as the fractions already have the same denominator (3).
A.20%
Because if we change 20% to 100% , you will need to multiply it by 5. The difference of 20 and 16 is 4, and 4×5=20
Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres
Scale factor should be 20.
10 plus 20 is 30 (figure B) therefore 15 plus 20 should be 35
If the length of JK is 16.4 miles, it will be diameter of this circle, the radius will be JK/2 = 8.2 miles
As we know the length of circle is 2π*r in this case r = 8.2
The arc JM is 1/4 length of the whole circle so arc JM = (2π*8.2)*(1/4) = 2π*8.2/4 = π*8.2/2 = π*4.1
if we assume that π=3.14 the answer will be 3.14 * 4.1 = 12.874.... And as the answer needs to be rounded to the nearest tenth it will be 12.874≈12.9
So the answer will be 12.9
