18 mins.
Explanation:
Time taken to travel 20 m = 1 min
Time taken to travel 360m = x min
therefore:
1/20=x/360
(cross multiply)
20 x =360(isolate x by dividing both sides by 20)
x = 360
20 x
= 18 mins.
Answer:
The answers are letters A,B,and C
Answer:
x=31
Step-by-step explanation:
QPC is a triangle. All angles of a triangle adds up to 180.
(x+11)+(2x+6)+70=180
x+11+2x+6+70=180
Combine like terms
3x+87=180
Subtract 87 from both sides
3x+87-87=180-87
3x=93
Divide both sides by 3
x=31
Answer:
9
Step-by-step explanation:
Given that:
Dimension of Original photo = 4 inches by 6 inches
Intended dimension of model = 3 feet by 4 1/2 feets
Converting from feets to inches :
1 foot = 12 inches
Therefore,
Intended dimension of model :
3 feets = (3 * 12) = 36 inches
by 4 1/2 feets = (4 1/2 * 12) = 54 inches
Hence, scale factor required :
36 /4 = 9
54 / 6 = 9
Scake factor = 9
