Answer:3 by 1
Step-by-step explanation:
okay so I'll say the long side of a tile as x
the short side of a tile as y
look at the short side of the big patio first, it's made up of 2 big and 2 small
so 2x+2y=8 or x+y=8 so two added together is 8. So one possibility is 3 and 1 because (3+1)2 = 9
Step-by-step explanation:
Let's say b is the rate of the boat in still water, and c is the rate of the current.
Distance = rate × time
Going upstream:
100 = (b − c) (5)
20 = b − c
Going downstream:
100 = (b + c) (2)
50 = b + c
Solve the system of equations using substitution or elimination. Using elimination, add the equations together:
70 = 2b
b = 35
c = 15
The boat's speed is 35 km/h, and the current's speed is 15 km/h.
Answer:
Step-by-step explanation:
WeknowthatsinceABCisarightangledtriangle,
AB2+BC2=AC2
82+152=AC2
64+225=AC2
AC2=289
AC=289−−−√=17
Hypotenuse=17cm
I think not because a square has four sides and a triangle has three.
Answer:
50%
Step-by-step explanation:
So there are 90 2 digit numbers. There are 45 2 digit odd numbers.
The probability should be 50%
