Answer:
1)
Ratio is 1:1.
2)
The required number is:
Step-by-step explanation:
1)
Let us consider that Cecilia's has a total of 'x' CDs
and let 'y' represent the number of Jazz CDs.
Now we are given information that:
1/5 of her Jazz CDs represents 1/10 of all her CDs.
i.e.
i.e. the Jazz CDs are half of the total CDs.
Hence, the number of Non-Jazz CDs(z)
=
Hence, the ratio of Jazz to Non-Jazz CDs
Hence, the required Ratio is 1:1.
2)
How would you change to a number times 25?
We will find the number by dividing the quantity by 25 to find the required number.
i.e.
Hence the required number is:
Yes they can all have the same
Answer:
Step-by-step explanation:
two points on it are (-1,0) and (0,1)
slope= (1-0)/(0-(-1))=1/1=1
eq of line is y-0=1(x+1)
y=x+1
let y>x+1
put x=0,y=0
0>0+1
or 0>1
which is false .
Hence y<x+1
or x+1>y
or x-y+1>0
v=bh therefore v=(212)(112)
So the volume would be 23744 cm^3
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
