Answer:
Finding 1/5 of something is the same as dividing that number by 5. Since 24 isn't divisible by 5, 24 / 5 is not an integer. Since you can't have 4.8 species of animals the answer to (a) is no.
For (b), 1/3 * 24 = 8 and 24 - 8 = 16.
Answer:
1.25π
Step-by-step explanation:
Hello There!
The area of a sector can be found using this formula
where 0 = angle and r = radius
so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula
so...
so the area of the sector = 1.25π
Note: it says to leave your answer in terms of pi so we do not have to apply pi
Answer:25 parts of water to be added in 5 parts of powder .
Step-by-step explanation:
The ratio of powder to water required for a medicine is 1:5
If we have 5 parts of powder
To find : Parts of water to be added
Let x be the parts of water added when there is 5 parts of powder
Therefore we have
Powder 1 5
Water 5 x
Clearly, it is in direct variation
So we have
Hence, 25 parts of water to be added in 5 parts of powder.

Answer:
a=2
b=5
Step-by-step explanation:
5a=2b
a=2/5b
2(2/5b) -3b= -11

-2.2b=-11
b=5
5a=2*5=10
a=2
