Answer:
32
Step-by-step explanation:
There are 80 biscuits inside the tin.
Also, they said that those biscuits are in the ratio
Short bread : Choc - chip
2 : 3
Altogether there are 5 shares ( 2 + 3)
And now you can divide 80 by 5 to find how many biscuits contain per a share.
80 ÷ 5 = 16
In the question, they asked us to to find the number of short biscuits inside the tin.
Let us find that.
There are 2 shares for short bread biscuits.
So,
Number of short biscuits ⇒ 2 × 16
⇒ 32
Hope this helps you :-)
Answer:
x≥5
Step-by-step explanation:
-1 ≥ x/-5
x/-5 ≤ -1
x(-1)/5 ≥ (-1) (-1)
x/5 ≥ 1
5x/5 ≥ 1 ×5
x ≥ 5
I'm not sure but I tried.
For the graph: you can draw a line about 15cm, put 0 at the start then after 5cm put 5 then 10 at 10cm and 15 at the end. At 5 put • that's the starting and go all the way to 15 and add > to show that the line continues. I'm not good at explaining but I hope it helps.
Answer:
A
Step-by-step explanation:
Basically, this is an observational study because the researcher does not apply any treatment.
It's not an experiment because there is no experimentation involved. :)
It's not double-blind because in that case the researcher would have to apply something to two kinds of groups. one aware one the other not. not the case.
It's not D because The observations are comparing two kinds of subjects and they are not looking for a cause and effect.
Since I don't see attachment, I guess the solution will be as follows:
1 & 3/4 , since 1 = 4/4, then it could be rewritten :
4/4 & 3/4, hence between these 2 fraction there is 2/4 or 1/2.
