0.9 because 10 divided by 11 is 0.909...
Answer:
x=19.4
Step-by-step explanation:
a^2+b^2=c^2
x^2+8^2=21^2
x^2+64=441
x^2=377
square root of 377 is 19.41648784
rounded would be 19.4
Answer:
12
Step-by-step explanation:
There are 32 female casts in a school play
The ratio of male to the female role is 3:8
Therefore the number of male casts in the school play can be calculated as follows
3/8= x/32
Cross multiply
8x = 32×3
8x= 96
x= 96/8
= 12
Hence there are 12 male casts in the school play
A) you need to do 2+3=5 then divide £20 by 5 which equals 4, the ratio is 2:3 so you do 4x2 which equals 8 then you do 4x3=12. So your answer would be 8:12
