Answer:
0.44ft/hr
Step-by-step explanation:
Given parameters:
Quantity of rainfall = 8inches
1ft = 12inches
so;
= 0.67ft
Time =
hr
Unknown:
Rate of rainfall expressed in ft/hr = ?
Solution:
The rate of the rainfall is given as;
Rate =
Rate =
= 0.44ft/hr
Answer:
1. area of new pen = 11

2. i. 5 feet by 2
feet
ii. 2 ½ feet by 4 ½ feet
Step-by-step explanation:
The size of the pen as planned = 5 ft long by 4 ½ ft wide
Area of the pen = length x width
= 5 x 4 ½
= 5 x 
Area of the pen = 
= 22 ½ 
But, Krista has to make the pen ½ the size of planned. So that;
area of new pen = ½ x 22 ½
= ½ x 
= 
= 11 
area of new pen = 11

The area of the new pen would be 11
.
The possible values she could use are:
i. 5 feet by 2
feet
ii. 2 ½ feet by 4 ½ feet
Answer:
13 4/9
Step-by-step explanation:
Answer:
5 min
Step-by-step explanation:
time taken=distance required to travel/speed of train
total distance train have to cover to just left the tunnel is (lenght of tunnel+length of train) =2km+250m
=2250m
speed of train is 27km/hr
multiply 5/18 to convert in m/s
i.e, (5/18)×27=7.5m/s
now time taken =2250m/(7.5m/s)
=300s
and,300s =5min
36864 inch.
because you multiply 32 * 48 * 24 to get the volume
