The water depth of a pond is initially 36 inches and decreases at a rate of 0.2 inches per day through evaporation. Write a linear function that represents the depth of the pond at a given time.
Answer:
36-0.2d
Step-by-step explanation:
d refers to the number of days
This should work for your question if not I'm very sorry
The required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.
The equation is the relationship between variables and constants represented as y = ax + b is an example of a polynomial equation.
Here,
The water depth of a pond is initially 36 inches
The water depth of a pond decreases at a rate of 0.2 inches per day through evaporation.
Let the number of the days be x , and the depth left be y
According to the question,
Total depth in x days = 0.2x
Total remaining depth = 36 - 0.2x
or
y = 36 - 0.2x
Thus, the required expression for the decreasing depth of the pond is y = 36 - 0.2x, Where y is the depth of the pond after x days.

The half-life of Palladium-100 is 4 days. After 24 days a sample of Palladium-100 has been reduced to a mass of 7 mg.
A.) What was the initial mass (in mg) of the sample?
B.) What is the mass (in mg) 4 weeks after the start?
You may enter the exact value or round to 4 decimal places.
9514 1404 393
Answer:
A) 448 mg
B) 3.5 mg
Step-by-step explanation:
24 days is 24/4 = 6 half-lives. That is, the mass of 7 mg is 2^-6 times the initial mass.
A) The initial mass is 2^6×(7 mg) = 448 mg
__
B) 4 weeks is 28 days, or 7 half-lives. The remaining mass will be half the amount after 6 half-lives.
(7 mg)/2 = 3.5 mg . . . . remaining after 4 weeks

O A. r =
6V
B. r = 6V – 7
O c. r= = v
OD. r= 16V (11)
Answer:
A) r=∛(6v)/[tex]\pi[/tex]
Step-by-step explanation:
v=1/6[tex]\pi[/tex]r³
v÷1/6=[tex]\pi[/tex]r³
(when dividing by a fraction, invert and multiply)
6v=[tex]\pi[/tex]r³
6v÷[tex]\pi[/tex]=r³
(6v)/[tex]\pi[/tex]=r³
take the cube root of both sides
∛(6v)/[tex]\pi[/tex]=∛r³
∛(6v)/[tex]\pi[/tex]=r
Some biology students were checking eye color in a large number of fruit flies. For the individual fly, suppose that the probability of white-eyes is 1/4 and the probability of red-eyes is 3/4. We may treat these observations as independent Bernoulli trials. what is the probability that at least 3 flies have to be checked for eye color to observe a white-eye fly?
Answer:
0.5625 = 56.25% probability that at least 3 flies have to be checked for eye color to observe a white-eye fly.
Step-by-step explanation:
A sequence of independent Bernoulli trials is the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
What is the probability that at least 3 flies have to be checked for eye color to observe a white-eye fly?
This is the probability of no white-eyes during the first two flies, that is, [tex]P(X = 0)[/tex] when [tex]n = 2[/tex]
Probability of white-eyes is 1/4
This means that [tex]p = \frac{1}{4} = 0.25[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{2,0}.(0.25)^{0}.(0.75)^{2} = 0.5625[/tex]
0.5625 = 56.25% probability that at least 3 flies have to be checked for eye color to observe a white-eye fly.

If you jog 8 times around a track that is 600 meters long, how many kilometers have you covered?
Answer:
0.6 km
Step-by-step explanation:
If If you jog 8 times around a track that is 600 meters long, then 4.8 kilometers you have covered
What is Unit of Measurement?A Unit of measure is the actual unit in which the associated values are measured.
Given,
If you jog 8 times around a track that is 600 meters long,
We need to find how many kilometers you have covered.
8 times around a track that is 600
It means we have to multiply eight with six hundred.
8×600
=4800
We know that 1 km is 1000 m
So divide 4800 by 1000 to find in kilometers
4800/1000=4.8km
Hence If you jog 8 times around a track that is 600 meters long, Then 4.8 Kilometers you have covered.

what is the value of x?

Answer:
A. 2
Step-by-step explanation:
Given:
DC = 1
CE = x + 4
AB = 11
BE = x + 1
Required:
Value of x
Solution:
(DC + CE) × CE = (AB + BE) × BE
(1 + x + 4) × (x + 4) = (11 + x + 1) × (x + 1)
(x + 5) × (x + 4) = (x + 12) × (x + 1)
x² + 4x + 5x + 20 = x² + x + 12x + 12 (distributive property)
x² + 9x + 20 = x² + 13x + 12
Collect like terms
x² - x² + 9x - 13x = - 20 + 12
-4x = -8
Divide both sides by -4
x = -8/-4
x = 2

Answer:
17.67 mpg
Step-by-step explanation:
The fuel efficiency is given by :
[tex]\eta=1.437+0.541\times s[/tex]
We need to find the fuel efficiency for a speed of 30 mph
Put the value of s equals 30 mph in the above equation.

Answer:
x = 25°
y = 25°
Step-by-step explanation:
✔️(x + 35)° + 30° + 90° = 180° (sum of triangle)
x + 35 + 30 + 90 = 180
Add like terms
x + 155 = 180
x + 155 - 155 = 180 - 155
x = 25°
✔️(y + 30)° + 35° + 90° = 180° (sum of triangles)
y + 155 = 180
y = 180 - 155
y = 25°
