Surface area of larger box is 69% more so as a scale factor that is 1.69
Square root 1.69 = 1.3
Height of smaller box x 1.3 is height of larger box.
18 x 1.3 = 23.4 cm
Height = 23.4 cm
Answer:
27
13
4
Step-by-step explanation:
3/9=27
6+7=13
5-1=4
The top and bottom are the same length:
5x +10 = 40
Subtract 10 from each side:
5x = 30
Divide both sides by 5:
x = 30/5
x = 6
Step-by-step explanation:
The approximate stopping distance d(in feet) is given by the formula :
...(1)
Where
v is the speed of the car in mph
We need to find the speed of the car when the distance is 200 feet
Put d = 200 in equation (1)
It is a quadratic equation. Divide the above equation by 0.05.
The solution of the above equation is given by :
Since, 1 mph = 5280 ft/hour
44.96 ft/h = 0.00851 mph
-88.96 = -0.0168 mph
Hence, this is the required siolution.
