Answer:
0.025 Kg/ cm²
Step-by-step explanation:
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion :
[tex]y = \frac{b}{x}[/tex]
where b = constant of proportionality
to determine the answer in this question :
1. determine constant of proportionality
200 = k / 32
k = 6400
2. Determine the amount of pressure using the constant of proportionality
256, 000 = 6400 / pressure
pressure = 6400 / 256, 000 = 0.025

Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 35 h from the time Henrietta started the experiment. I need help asap please
Answer:
See belowStep-by-step explanation:
Given
Initial number of bacteria = 800Growth rate = 3.2% = 1.032 timesRequired equation:
B(t) = 800(1.032)^t, where B- number of bacteria, t- time in hoursThe y-intercept is:
B(0) = 800*1.032^0 = 800The point (0, 800)Bacteria population 35 in hours:
B(35) = 800*1.032^35 = 2409The point (35, 2409)Given that events A and B are independent with P(A)=0.5 and P(B)=0.15, determine the value of P(A∣B), rounding to the nearest thousandth, if necessary.
The value of the independent variable probability is P ( A | B ) = 0.5
Given data ,
Let the independent events be represented as
P ( A ) = 0.5
P ( B ) = 0.15
Now , the value of the probability P ( A | B ) is given by
And , if events A and B are independent, then P(A|B) = P(A). Therefore, in this case, P(A|B) = P(A) = 0.5
Hence , the probability is P ( A | B ) = 0.5

A bag with 10 marbles has 2 yellow marbles, 4 blue marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?
Answer:
P(Y) = 2/10 = 1/5
Step-by-step explanation:
From the above question:
Total number of marbles = 10 marbles
Number of yellow marbles = 2 yellow marbles
Number of blue marbles = 4 blue marbles
Number of red marbles = 4 red marbles.
The probability of choosing a marble that is yellow is calculated as:
= P(Y) = Number of yellow marbles/Total number of marbles
P(Y) = 2/10
P(Y) = 1/5

Carlo and his brother, agreed to buy a bicycle by sharing out the cost. The ratio of the amount of money paid by Carlo to that paid by his brother was 5: 2. The bicycle cost P3500. Find the amount paid by each of them.
Answer:
Carlo paid 2500 dollars and his brother paid 1000 dollars
Step-by-step explanation:
Given -
The ratio of cost shared by Carlo and his brother is 5:2
Which means Carlo paid 5/7th part of the total cost of bicycle
5/7 * 3500 = 2500 dollars
The amount paid by his brother is 3500 - 2500 = 1000 dollars

the first 4 terms of a 10-term geometric series are listed below. Which expression represent the sum of the series? need ASAP
16/25+8/5+4+10+...+a^10
Using geometric sequence concepts, it is found that the sum of the first 10 terms is of 4068.6.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.The sum of the first n terms is given by:
[tex]S_n = \frac{a_1(q^n-1)}{q - 1}[/tex]
In this problem, the sequence is:
[tex]\frac{16}{25}, \frac{8}{5}, 4, 10,...[/tex]
Hence:
[tex]a_1 = \frac{16}{25}, q = \frac{10}{4} = 2.5[/tex]
Then, the sum of the first 10 terms is:
[tex]S_{10} = \frac{\frac{16}{25}(2.5^{10}-1)}{2.5 - 1} = 4068.6[/tex]

6. The swing set on the playgrounds is getting wobbly, and you have been asked to put outrigger boards to help stabilize it. If the crossbar of the swing is 10 feet off of the ground, the outrigger to be attached at a 40 degree angle, and you want to bury the outrigger boards 3 feet onto the ground, how long would the boards have to be? (Hint: the outrigger is the hypotenuse of a right triangle)
Answer:
[tex]X=18.6ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of swing's crossbar [tex]H=10ft[/tex]
Angle [tex]\theta=40 \textdegree[/tex]
Depth of outrigger [tex]d_=3ft[/tex]
Generally the equation for slant height l is mathematically given by
[tex]l=\frac{opposite}{sin\theta}[/tex]
Therefore
[tex]l=\frac{H}{sin\theta}[/tex]
[tex]l=\frac{10}{sin 40\textdegree}[/tex]
[tex]l=15.6ft[/tex]
Since the Depth of outrigger
[tex]d_=3ft[/tex]
Therefore Length of the board X
[tex]X=l+d[/tex]
[tex]X=15.6+3[/tex]
[tex]X=18.6ft[/tex]
