the answer is 52 in each bus.
4 students rode in a car means 472-4=468
if 468 students were divided into 9 buses then 472÷9=52
<A = <B
5x - 18 = 3x + 42
2x = 60
x = 30
<A = 5(30) - 18 = 132
Answer:
C. the probability of it not happening is 0.3.
Step-by-step explanation:
Probability of event happening is of 0.7.
Either it happens, or it does not. The sum of these probabilities is 100%.
0.7 probability of happening, so 1 - 0.7 = 0.3 probability of not happening, and the correct answer is given by option C.
A is wrong as the probability is not 1, and B is wrong as the probability is higher than 0.5.
Answer:
Rational numbers can be written as a fraction where p and q are integers and q is not equal to zero
Answer:
0.28cm/min
Step-by-step explanation:
Given the horizontal trough whose ends are isosceles trapezoid
Volume of the Trough =Base Area X Height
=Area of the Trapezoid X Height of the Trough (H)
The length of the base of the trough is constant but as water leaves the trough, the length of the top of the trough at any height h is 4+2x (See the Diagram)
The Volume of water in the trough at any time
=8h(8+2x)
V=64h+16hx
We are not given a value for x, however we can express x in terms of h from Figure 3 using Similar Triangles
x/h=1/4
4x=h
x=h/4
Substituting x=h/4 into the Volume, V
h=3m,
dV/dt=25cm/min=0.25 m/min
=0.002841m/min =0.28cm/min
The rate is the water being drawn from the trough is 0.28cm/min.
