An element with a mass of 120 grams decays by 27.5% per minute. To the nearest tenth of a minute, how long will it be until there are 2 grams of the element remaining?
Answer:
12.7
Step-by-step explanation:
its right
It will take approximately 9.9 minutes until there are 2 grams of the element remaining.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We can use the exponential decay formula to solve the problem.
The formula for exponential decay is:
[tex]A = A_0e^{-kt}[/tex]
where:
A₀ = initial amount
A = amount remaining after time t
k = decay rate constant
t = time
We can find the decay rate constant k using the given percentage decay per minute.
If the element decays by 27.5% per minute, then the decay rate constant is:
k = ln(1 - 0.275) = -0.3185
where ln is the natural logarithm.
Let's substitute the given values into the formula and solve for t:
[tex]2 = 120 e^{-0.3185t}[/tex]
Divide both sides by 120:
[tex]0.0167 = e^{-0.3185t}[/tex]
Take the natural logarithm of both sides:
ln(0.0167) = -0.3185t
t = ln(0.0167) / (-0.3185)
t ≈ 9.9 minutes (to the nearest tenth of a minute)
Therefore,
It will take approximately 9.9 minutes until there are 2 grams of the element remaining.

The volume of a cylinder can be found using the formula V = pi r squared h.
Which is the correct first step in finding the height of a cylinder with a volume of 192 pi cubic inches and a radius of 5 inches?
5 = pi (192) squared h
V = pi + (5) squared + 192 pi
V = pi (5) squared (192)
192 pi = pi (5) squared h
Answer:
The answer is D
192 pi = pi (5) squared h
Step-by-step explanation:
Answer:
The answer is D
Step-by-step explanation:
It points out to find the height and it already gives you the volume and radius so all you have to do is plug in those to #'s.
So the "V" is always going to go first then the equal sign the the pi sign then a number followed by squared.
Right after that you should have an "H" which is the height you have to use to multiply.

Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted:
Write an equation to determine the area, A, of the patio that will be painted.
A = (x + 18)(x + 35)
A = (x + 15)(x + 25) + 30
A = (x + 5)(x + 22)
A = (x + 25)(x + 15) − 30
Answer:
A = (x + 25)(x + 15) - 30
Step-by-step explanation:
This question is not complete without a figure; find the figure attached.
Marissa is painting a regular patio with dimensions as
Length = (x + 25) units
Width = (x + 15) units
Area of this rectangular patio = Length × Width
Area = (x + 25)(x + 15) unit²
She has to paint the patio except the bench that does not need to be painted.
Dimensions of the rectangular bench,
Length = 10 units
Width = 3 units
Area of the bench = 10×3 = 30 units²
Area of the patio to be painted = Area of patio - Area of bench
A = (x + 25)(x + 15) - 30

When two pipes fill a pool together, they can finish in 4 hours. If one of the pipes fills half the pool then the other takes over and finishes filling the pool, it will take them 9 hours. How long will it take each pipe to fill the pool if it were working alone?
The faster pipe will fill the pool in 6 hours and the slower pipe will fill the pool in 12 hours.
What is time and work for commercial mathematics?Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.
Given here, two pipes fill the pool in 4 hours if they work together and If one of the pipes fills half the pool then the other takes over and finishes filling the pool, it will take them 9 hours.
Let volume of the pool be LCM(9,4)= 36 unit³ and their efficiencies be E₁ and E₂ respectively then we have E₁+E₂ = 36/4
=9 units
Also 18/ E₁ +18/E₂ = 9
putting E₁=9-E₂ we get
18₁/ 9-E₂ +18/E₂ = 9
E²₂ -9E₂ +18 =0
(E₂ +3) (E₂ -6) =0
Therefore E₂ =6 units as efficiency cannot be negative and consequently E₁ =3 units
Hence, if they are working alone they finish the work in 36/3 =12 hours and 36/6=6 hours respectively.

The angle of depression between a bird and its prey is 70 degrees. If the bird is 18 ft off the ground, what is the distance between the bird and its prey? Round to the nearest foot
Answer:
19 ft
Step-by-step explanation:
We are given that
[tex]\theta=70^{\circ}[/tex]
Height of bird from the ground=h=18 ft
We have to find the distance between the bird and its prey.
We know that
[tex]sin\theta=\frac{perpendicular\;side}{hypotenuse}[/tex]
Using the formula
[tex]sin70=\frac{18}{hypotenuse}[/tex]
[tex]hypotenuse=\frac{18}{sin70}=19.1 ft\approx 19ft[/tex]
Hence, the distance between the bird and its prey=19 ft
Mark sold 445 tickets for the school play. Student tickets cost $3 and adult tickets
cost $5. Mark's total income for the event was $1871. How any adult tickets did he
sell?
Answer:
Mark sold 268 adult tickets.
Step-by-step explanation:
We are given the following in the question.
Let x be the number of students ticket sold and y be the number of adult tickets sold.
Total number of tickets sold = 445
Thus, we can write the equation:
[tex]x + y = 445[/tex]
Cost of student ticket = $3
Cost of an adult ticket = $5
Total income = $1871
Thus, we can write the equation:
[tex]3x + 5y = 1871[/tex]
Solving the two equations, we get,
[tex]3x + 5y - (3x+3y) = 1871 - 3(445) \\2y = 536\\\Rightarrow y = 268\\\Rightarrow x = 445 - 268 = 177[/tex]
Thus, Mark sold 268 adult tickets.
Answer:he sold 268 adult tickets at the school play

Mai's water bottle had 24 ounces in it. After she drank x ounces of water, there were 10 ounces left. Select all the equations that represent this situation.
Answer:
x+10=24
Step-by-step explanation:
the actual equation would give you 14
To represent the situation, you can use the equation x = 24 - 10 or the proportion x/24 = 10/24.
Explanation:To represent the situation, we can use the equation: x = 24 - 10, where x represents the amount of water Mai drank. This equation represents the fact that the initial amount of water in the bottle (24 ounces) minus the amount of water that Mai drank (x ounces) equals the remaining amount of water (10 ounces).
Alternatively, we can also use the proportion x/24 = 10/24 to represent the situation. This proportion shows that the ratio of the amount of water Mai drank to the initial amount of water in the bottle is equal to the ratio of the remaining amount of water to the initial amount of water.
