Answer:
Step-by-step explanation:
10 cm represents 5 meters in the real world
6 cm represents x meters
cross multiply
10x = 5*6
10x = 30
x = 3 meters so 6cm is equal to 3 meters in length
10 cm represents 5 meters in the real world.
5 cm = y meters
10y = 5*5
10y = 25 m
y = 25/10 meters = 2.5 meters
Area of the room = 2.5 * 3 = 7.5 square meters
Answer:
-2
Step-by-step explanation:
its -2 cuz to find the slope the equation is the second y - the first y over the second x - the first x so -5 - 5 is 10 over 3 - -2 is 5 so it would be -10/5 which simplifies to -2
Answer:
AC = 28 feet
Step-by-step explanation:
Point C is the midpoint of AB, so AC is half the length of AB:
AB/2 = (56 ft)/2 = 28 ft = AC
