Given that Joseph has 24 cousins, and he has 6 more females than males, the number of females will be obtained as follows;
suppose he had x males, number of females will be x+6.
The total will be:
x+(x+6)=24
x+x+6=24
2x+6=24
2x=24-6
2x=18
x=18/2
x=9
thus the number of male cousins is 9, the number of female cousins will be 9+6=15
We therefore conclude that he has 9 male cousins and 15 female cousins
Answer:
First of all you need to know the
it's equal to 2 and
which is the number is between 1 and 2 and between that number there maybe the possibilities of above 0.5 or under 0.5
After that Figure out which one was bigger?
or
? The answer is
and
also near to
so it should be above 0.5 .
So we know that
is between 1 and 1.5.

8 litres (amount of 20% solution needed) and 7 litres for (amount of 50% solution needed)
<u>Step-by-step explanation:</u>
Let consider ‘x’ for 20% acid solution and (15 – x) for 50% acid solution. And so, the equation would be as below,
20% in x + 50% in (15 – x) = 15 litres of 34%
Convert percentage values, we get
0.20(x) + 0.50 (15 – x) = 15 (0.34)
0.20 x + 7.5 – 0.50 x = 5.1
-0.3 x + 7.5 = 5.1
0.3 x = 7.5 – 5.1
0.3 x = 2.4

Apply ‘x = 8’ value in (15 – x) we get,
15 – 8 = 7 litres
The value of 7 litres for (amount of 50% solution needed)
Answer:7
Step-by-step explanation:
all you have to do is subtract 20-13
Answer:
sqrt239
Step-by-step explanation:
Using the pythagoream thereom, we know that a^2+b^2=c^2.
so x^2+17=256
That makes x the square root of 239.
