7/9 because if you simplify 21/27 you have to divide it by something that can go into both equally, which in this case is 3
Answer:
It will cost: £28.28
Step-by-step explanation:
Area of sphere = 4 x π x r2
Area of Circle = 4 x π x 3^2 = 113.097 (radius is half of diameter)
113.097 / 0.25 = 28.28
Given:
total = 750
ratio = 7 : 8
We need to get the ratio of the number to its total
7 + 8 = 15 ; 7/15 and 8/15 is the ratio of the number to its total.
We multiply these ratio to the total of 750
7/15 * 750 = 350
8/15 * 750 = 400
7:8 is equal to 350:400
Answer:
-7/10
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= ( 4 - -3)/( -6 - 4)
= ( 4+3)/( -10)
-7/10
