Answer:
£3.25
Step-by-step explanation:
You would add £1.25 and £00.50 which is £1.75 then you would do £5.00-£1.75 which is £3.25
Find a common denominator between 12 and 9
it would be 36
9*4=36
12*3=36
1*3=3
7*4=28
3/36 + 28/36 = 31/36
Answer:

Step-by-step explanation:
It is given that,
Mass of benzene, m = 0.1 L
Mass, m = 36.4 g
We know that, 1 L = 1000 cm³
0.1 L = 100 cm³
The density of an object is equal to its mass divided by its volume. So,

So, the density of benzene is
.
Answer:
known side: hypotenuse
Step-by-step explanation:
What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
