Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get
and solve to get 576 inches or 576/12 = 48 feet
Answer:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 5y = 15x - 4
[2] y = 3x - 4/5
// Plug this in for variable y in equation [1]
[1] 15x - 20•(3x-4/5) = 7
[1] -45x = -9
// Solve equation [1] for the variable x
[1] 45x = 9
[1] x = 1/5
// By now we know this much :
x = 1/5
y = 3x-4/5
// Use the x value to solve for y
y = 3(1/5)-4/5 = -1/5
Solution :
{x,y} = {1/5,-1/5}
Answer:
Most likely yes... there is a problem in the way you asked your question ...
if the question is then the answer is yes and the constant is -4/5's
If by some chance the actual question is (you can not tell by the way y0u presented tis problem.. then the answer would be NO it would be "inverse" relation
Step-by-step explanation:
Answer: 880 cm
Step-by-step explanation:
Given: Radius of the hula hoop = 35 cm
Hula hoop is circular in shape
Then, Circumference = , where r = radius
Now , Circumference of hula hoop =
Now , the distance the hula hoop rolls in 4 full rotations = 4 × (Circumference of hula hoop)
Hence, the required distance = 880 cm
