An element with a mass of 840 grams decays by 22.9% per minute. To the nearest minute, how long will it be until there are 70 grams of the element remaining?
Answer:10
Step-by-step explanation:believe me bro
To the nearest minute, it will be 10 minutes until there are 70 grams of the element remaining.
How to find the time it took for an element to decay to a certain mass?The time the element took to decay can be found by using the following formula:
[tex]F=P(1-r)^{t}[/tex]
Where:
F is the remaining mass.P is the original mass of the element.r is the rate at which the element is decaying.t is the time it took for the element to decay.We can find the answer by substituting the values.
[tex]F=P(1-r)^{t}\\\Rightarrow 70=840(1-0.229)^{t}\\\Rightarrow \frac{70}{840} =(1-0.229)^{t}\\0.0833=(1-0.229)^{t}\\t=9.56\\\approx10 \text{ minutes}[/tex]
Therefore, we have found that the element will take around 10 minutes to have 70 grams remaining.

What is 3.72 of 0.6?
Answer:
Since I do not know the context of the question I will list answers I think it could be based on what you asked:
1. 3.72 x 0.6 = 2.232
2. 3.72 ÷ 0.6 = 6.2
3. 3.72% of 0.6 = 0.02232

How does the volume of a cylinder with a radius of 6 inches and a height of 8 inches compare to
the volume of a cylinder with a radius of 8 inches and a height of 6 inches?
Answer:
they are the same
Step-by-step explanation:
We can conclude that the volume of cylinder 1 is 3/4 times the volume of cylinder 2.
What is the volume of cylinder?The volume of cylinder is given by -
V = πR²h
Given is to compare the volume of a cylinder with a radius of 6 inches and a height of 8 inches compare to the volume of a cylinder with a radius of 8 inches and a height of 6 inches.
Volume of cylinder 1 will be -
V(1) = πR²h = 6 x 6 x 8π = 36 x 8π = 288π
Volume of cylinder 2 will be -
V(2) = πR²h = 8 x 8 x 6π = 64 x 6π = 384π
So, we can write that -
V(1)/V(2) = (288π)/(384π)
V(1)/V(2) = (288)/(384)
V(1)/V(2) = 3/4
Therefore, we can conclude that the volume of cylinder 1 is 3/4 times the volume of cylinder 2.

A new experimental tank is in the shape of a cone, cylinder and sphere. All of the tanks have a volume of 10,000 cm3 . One condition to this tank is that the Radius should be 10 cm. Follow up the questions below based on this scenario.
Find the height of cylinder . Keep the answer in terms of π
Answer:
100/π cm
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 10,000cm³
Radius = 10cm
The formula for the height of a cylinder is obtained as:
V = πr²h
h = V/ πr²
h = 10000 /π × 10²
h = 10000 /π × 100
h = 100/π cm
The height of the cylinder in terms of π = 100/π cm

WHT IS THE CIRCUMFERENCE OF THE CIRCLE SHOWN IN THE PICTURE? (Also show the process or tell me what the radius or diameter of the circle is)
Answer:
109.9 cm
Step-by-step explanation:
Circumference = (pi)(diameter)
They tell you diameter = 35
c = (3.14)(35)
c = 109.9 cm
Please lmk if you have questions.
Answer:
circumference : 109.96 cm
Step-by-step explanation:
The radius of a circle is half its diameter. The radius of a circle with a diameter of 35cm is 17.5cm.
The circumference of a circle is found by 2πr . So that would be 2π 17.5
which would be equal to 109.96cm (2 sig. fig.).
The area of a circle is found by πr2 . So that's π⋅17.5 which is equal to 962.11cm (2 sig.fig.).

Brayden invests money in an account paying a simple interest of 3.3% per year. If he invests $30 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?
Answer:
$30.99
Step-by-step explanation:
The formula for simple interest is I = PRT where I = interest earned, P = principal amount borrowed/deposited, R = rate as a decimal, and T = time in years.
I = (30)(0.033)(1)
I = 0.99
Then add that to the amount deposited ($30) and you're done.
30 + 0.99 = $30.99
Please let me know if you have questions.
