Answers
[volume of the composite figure]=volume of cylinder + volume hemisphere
volume cylinder=pi*r²*h
r=4 mm
h=7 mm
volume cylinder=pi*4²*7----> 351.68 mm³
volume of hemisphere=(4/6)*pi*r³
r=4 mm
volume of hemisphere=(4/6)*pi*4³----> 133.97 mm³
[volume of the composite figure]=351.68+133.97----> 485.65 mm³

The half-life of cobalt-60 is 5.20 yr. how many milligrams of a 2.000-mg sample remains after 6.55 years?
Answers
Answer:
0.835 mg of a 2.000-mg sample remains after 6.55 years.
Step-by-step explanation:
We are given that The half-life of cobalt-60 is 5.20 yr.
Formula of half life : [tex]N(t) = N(0)e^{\frac{-0.693t}{t\frac{1}{2}}}[/tex]
Where N(0) = Initial amount
N(t) = Quantity remaining after time
t = time
[tex]\frac{t}{2} =\text{half life}[/tex]
So, N(0) = Initial amount = 2 mg
t = time = 6.55 years
[tex]\frac{t}{2} =\text{half life} = 5.20 yr [/tex]
Substitute the values in the formula
Therefore,
[tex]N(t) = 2 e^{\frac{-0.693 \times 6.55}{5.20}}[/tex]
[tex]N(t) =0.835[/tex]
Hence 0.835 mg of a 2.000-mg sample remains after 6.55 years.

The volume of the cone is approximately 33.51 cubic feet when rounded to the nearest hundredth
Use the formula for the volume of a cone, which is:

a dump truck weighs 11.25 tons. a conveyor belt pours sand into the truck at a constant rate of 1/4 ton per minute. the dump truck weighs 18 tons when filled. at the same time the dump truck is being filled, an identical truck filled to capacity is being emptied at a rate of 1/8 ton per minute. how much sand is in each dump truck when the trucks are the same weight?
Answers
W1B = Weight of the truck 1 before starting the filling.
W1A = Weight of the truck 1 when filled.
R1F = Rate of change (Truck 1 being filled)
W2B = Weight of the truck 2 before starting the filling.
W2A = Weight of the truck 2 when filled.
R2F = Rate of change (Truck 2 being filled)
Given that a conveyor belt pours sand into the truck and stops when filled, then the amount of sand, when the truck is filled to capacity, is:
[tex]S = W_{1B} - W_{1A} = 18-11.25 = 6.75Tons[/tex]
Let's analyze Truck 1:
Given that the rate of change is:
[tex] \frac{1}{4} ton/min[/tex]
This means that in 1min the amount of sound poured is 1/4Ton, then the time elapsed when filled using rule of three is:
[tex]t = \frac{6.75}{ \frac{1}{4} } = 27min[/tex]
A similar analysis happens with Truck 2:
Given that the rate of change is:
[tex] \frac{1}{8} ton/min[/tex]
Then:
[tex]t = \frac{6.75}{ \frac{1}{8}} = 54min[/tex]
Now we can find two straight lines:
Truck 1:
[tex]\left \{ {{t=0min} \atop {S=0Ton}} \right. [/tex]
[tex] \left \{ {{t=27min} \atop {S=6,75Ton} \right[/tex]
[tex]S-S_{0} = m(t-t_{0})[/tex]
[tex]S-0 = \frac{6.75-0}{27-0} (t-0)[/tex]
∴ [tex]S = 0.25t[/tex]
Truck 2:
[tex] \left \{ {{t=0min} \atop {S=6.75Ton}} \right[/tex]
[tex] \left \{ {{t=54min} \atop {S=0Ton}} \right[/tex]
[tex]S-S_{0} = m(t-t_{0})[/tex]
[tex]S-6.75 = \frac{6.75-0}{0-54} (t-0)[/tex]
∴ [tex]S = -0.125t+6.75[/tex]
The trucks are the same weight when they have the same amount of sand, so solving for t:
[tex]0.25t = -0.125t+6.75[/tex]
[tex]0.375t = 6.75[/tex]
[tex]t = 18min[/tex]
Finally, the amount of sand in each truck:
[tex]S = 0.25(18) = 4.5Ton [/tex]
To find out how much sand is in each dump truck when they are the same weight, we can set up an equation based on the given information. Let's assume that the amount of sand in the first truck is x tons. We can then find the value of t that makes the weight of both trucks the same and substitute it into the equation to find x.
Explanation:To find out how much sand is in each dump truck when they are the same weight, we can set up an equation based on the given information.
Let's assume that the amount of sand in the first truck is x tons. Since the conveyor belt pours sand into the truck at a constant rate of 1/4 ton per minute, the weight of the sand will increase by (1/4) * t tons, where t is the time in minutes.
Similarly, the second truck is being emptied at a rate of 1/8 ton per minute. So, the weight of sand in the second truck will decrease by (1/8) * t tons.
We know that the dump truck weighs 11.25 tons initially and 18 tons when filled. Therefore, we can set up the equation:
11.25 + (1/4) * t - (1/8) * t = 18 - x
Simplifying the equation:
(1/4) * t - (1/8) * t = 18 - 11.25 - x
(1/8) * t = 6.75 - x
t = 6.75 * 8 - 8x
Now, we need to find the value of t that makes the weight of both trucks the same. Let's substitute that value into the equation to find x.
Suppose you are the treasurer of the drama club.The cost of scripts for the spring musical is $254. The cost of props and costumes is $400. You must also pay $1.20 per ticket to the play's director. You charge $4.00 per ticket and you also expect to make $150 on refreshments. How many tickets will the drama club need to sell to break even?
Answers
$254 +400 -150 = $504
Expected income per ticket is
$4.00 -1.20 = $2.80
To break even, the number of tickets that must be sold is
$504/$2.80 = 180
The drama club needs to sell 180 tickets to break even.

Linear sequenceFrom the question, we are to determine the next three terms in the given sequence
The given sequence is
-6,5,16,27, ...
From the given sequence, we can observe that the common difference of the sequence is 11
That is,
5 - -6 = 5 + 6 = 11
16 - 5 = 11
27 - 16 = 11
Thus, the next term after 27 will be
27 + 11 = 38
The next one will be
38 + 11 = 49
The next one will be
49 + 11 = 60
Hence, the next three terms of the given sequence are 38, 49, and 60. The correct option is A.38, 49, 60

Answer: well, in order to multiply fractions, you need to simply the particular fraction with the lowest terms (if they have any of course), then we multiply our numerators from each other so we can get a brand new numerator. (you do the same thing with denominators.

Hello There!
To multiply fractions, you first want to line up the numerator and the denominator together so they line up with each other.
Next, you want to multiply across. This includes multiplying the numerators together and then multiplying the denominators together.
Finally, you want to find the greatest common factor but only if the fraction can be simplified.
