Answer:
192 cm
Step-by-step explanation:
Given that:
Side length of small tiles = 12cm
Number of small tilea used to make a bigger tile = 4
The perimeter of larger tile:
Perimeter of a square = 4s
Where, s = side length
Side length of larger tile :
4 * side length of smaller tile
4 * 12
= 48 cm
Hence,
Perimeter of a larger square tile = 4s
4 * 48cm
= 192 cm
Answer:
a) x=5
b) x=6
Step-by-step explanation:
a)
3x+7=180-(10x-22)
3x+7=202-10x
13x=195
x=5
b)
11x-3=4x+39
7x=42
x=6
I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.
Choice a is a good one by the way
Answer:
Step-by-step explanation:
The population size is everybody running the race. It does not include people watching the race and it is not confined to just the 20 people the researcher talked to.
If it doesn't limit itself to the 20 people, then the 5 and 12 and 3 people are also too limiting.
Answer:
y = 16
Step-by-step explanation:
if x =10 then y =320
that means y= 32x
so if x = 1/2
y = 32*1/2
y= 16
