Answer:
12.63 km/hr
Step-by-step explanation:
Given the distance=240km
At 12 km/hr it will take =240/12 =20
time for Express train = 20-1=19
speed=240/19=12.63...km/hr
Answer:
1/12 (i think) or 0.083
Step-by-step explanation:
well she buys you 1 and there is 12 so it would be 1 out of 12 which is written as 1/12
Answer:
Step-by-step explanation:
7) The formula for determining the area of a parallelogram is expressed as
Area = base × height.
Length of base = Area/height
Therefore,
Length of base = 7/2 = 3.5 feet
8) The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of the bases
h is the height. Therefore
21 = 1/2(2 + 4)h
21 = 3h
h = 21/3 = 7 inches
9) Area = base × height.
Height = Area/Length of base
Height = 28/14 = 2 inches
10) a and b are 10 inches each.
Area = 1/2(a + b)h
Therefore,
35 = 1/2(10 + 10)h
35 = 10h
h = 35/10
h = 3 inches
Let the number of shaded square be x. And it is given that total number of squares are 25.
Substituting the values
Performing cross multiplication
So 5 squares should be shaded to create a region with a geometric probability of 0.2 .
Answer:
For the first one, you go from -4 on the number line and move 2 spaces to the right to get -2. For the second one, you start at -4 again and then you move to the left 2 spaces since your subtracting.
