1 foot = 30 cm
21 x 30 = 630 cm ( banner length)
1 meter = 100 cm
630/100 = 6.3 meters long
Answer:
2w
Step-by-step explanation:
The area of a square is given by a formula; A = a²
Substitute the A with the area 4w² and solve for the side length (a).
a = 2w
For this you should just look at the y value in each ordered pair.
The first one should be no.
second one: yes
third one: no
fourth one: no
Answer:
10√2
Step-by-step explanation:
This is a 45-45-90 triangle which means that the two non-hyptonouse lenghts are the same which means that the bottom lenght of the triangle is also 10 units
We can then use a^2+b^2=c^2 to solve for the last side
so we have
10^2+10^2=x^2
200=x^2
sqrt200=x
and I see that they want an exact answer so you simplify sqrt200 to
10√2
