5m-n
Just replace m with 4 and n with 9
5(4)-9=20-9=11
Answer:
x = 6
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Al ( A is the area of the triangular end and l is its length )
A =
bh = 0.5 × 9 × 4 = 18 cm² , then
V = 18 × 12 = 216 cm³
The volume of a cube is
V = s³ ( s is the side length ) , so
s³ = x³ = 216 ( take the cube root of both sides )
x =
= 6
I'll draw it for you cause im nice.
Ok so if you have 5ft on a square, all the sides are 5ft.
That mean that if its in half, one of the sides will be 2.5ft.
Now you can add 2.5 + 2.5 + 5+5 = 15.
So its 15 ft.
Answer:
3/2
Step-by-step explanation:
The ratio of males to females in a cycling club is 5:3.
1/3 of the males are under 18
2/9 of the females are under 18
The fraction of the club members that are under 18 is calculated as:
Male: Female = Male/Female
We are told in the above question:
1/3 of the males are under 18
2/9 of the females are under 18
Hence:
1/3 / 2/9
= 1/3 ÷ 2/9
= 1/3 × 9/2
= 3/2
The fraction of the club members that are under 18 is 3/2
