Area formula of a triangle:
given: base = 9 cm height = 4 cm
A = 1/2 bh
=1/2(9)(4)
=18 cm²

given: probability of rain - 0.03
of no rain - ?
1 - 0.03 = 0.97

Volume formula of a cuboid:
V = length x base x height
= 6 x 4 x 2.5
= 60 cm³
It means that it does not equal to that certain amount, which is why they put a line across it
Lol nice. to find the ribbon question we see that it says 5 meters. we divide this by 5. So x=$4/5
x= the cost of each meter. Simplify that and you will get $0.8 m\
now convert it to mm.
$0.8m x 1m/ 1000mm which equals 0.0008.
Answer:
f(x) = 3.7x + 3
Step-by-step explanation:
Using the fact that y = f(x), then rearrange the equation making y the subject.
- 3.7x = 3 - y ( add y to both sides )
y - 3.7x = 3 ( add 3.7x to both sides )
y = 3.7x + 3 , that is
f(x) = 3.7x + 3
