We know that for this equation, 360 is going to be our total. If the skyway's main span is 30 meters shorter, we will be subtracting 30 from whatever our x value is, as shown here:
360 = x - 30
To solve for x, we must do the opposite of the operation we see. The opposite of subtracting 30 is adding 30. So we must add 30 to both sides of our equation.
360 + 30 = 390
So,
x = 390
This means that the length of the main span of the dames point bridge is 390 meters. <span />
Solution :
Given :
The events are as follows :
P : Set of all the people
S : Set of people those who are single
C : Set of people having children
W : Set of women
M : Set of men
a). Now set of married women having children is given by :
And set of single women who do not have any children : (S -C) - M
Thus the set of women those who are either married and have children or they are single and they do not have any children is represented by :
b). Set of Married men :
Set of Married men :
Set of all possible married who are heterosexual couples, that is, all possible pairings of the married men and the married women is represented by :
c). The number of all the possible married heterosexual couples will be represented by the cardinality of the above set, which represents the number of the elements in the set.
Thus the number of the married heterosexual couples is given by :
Step-by-step explanation:
write equation in terms of x
y=(-6+3x)/12
from this equation u can see your gradient is 3/12 or 1/4
your perpendicular gradient is -1/m (m being the gradient of your main line)
so gradient of perpendicular= -4
since coordinate of main line is given, that point will also be on perpendicular.
so u have point and gradient so u can Calculate line equation
Y=MX+C
(-7)=(-4)(-1)+c
c=-11
y=-4x-11
^equation of perpendicular
You multiply 9 times nine 6 times. ~9*9*9*9*9*9~
Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.
