Answer:
[tex]F(t)=Ts+(T0-Ts)^{e-0.2t[/tex]
Step-by-step explanation:
Newton's law of cooling states
"that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"
Newton's Law of Cooling is given by the formula
[tex]F(t)=Ts+(T0-Ts)^{e-kt[/tex]
Where
F( t ) is the temperature of the object at a given time t
T s is the surrounding temperature
T 0 is the initial temperature of the object
k is the constant
Given k=0.2
Hence the expression is
[tex]F(t)=Ts+(T0-Ts)^{e-0.2t[/tex]

Step-by-step explanation:
Several different cheeses are for sale. The cheese comes in wedges
shaped like sectors of a circle. All of the wedges are the same height.
10a. Mai bought a wedge with a central angle of 45 degrees and radius 10
centimeters. What is the area of the top surface of this wedge? *
Answer:
39.30 [tex]cm^{2}[/tex]
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/[tex]360^{o}[/tex])[tex]\pi[/tex][tex]r^{2}[/tex]
where: θ is the central angle, and r is the radius.
Given that: central angle = [tex]45^{o}[/tex], radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/[tex]360^{o}[/tex])[tex]\pi[/tex][tex]r^{2}[/tex]
= [tex]\frac{45^{o} }{360^{o} }[/tex] x [tex]\frac{22}{7}[/tex] x [tex](10)^{2}[/tex]
= [tex]\frac{1}{8}[/tex] x [tex]\frac{22}{7}[/tex] x 100
= 39.2857
= 39.30 [tex]cm^{2}[/tex]
The area of the top surface of the wedge is 39.30 [tex]cm^{2}[/tex].
The area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².
What is the area of a circular sector?The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.
It can be calculated if theta is measure in radian as,
[tex]A_{sector}=\dfrac{r^2\theta}{2}[/tex]
It can be calculated if theta is measure in degrees as,
[tex]A_{sector}=\dfrac{\pi r^2\theta}{360}[/tex]
Here, (r) is the radius of the circle and (θ) is the central angle.
Several different cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height.
Mai bought a wedge with a central angle of 45 degrees and radius 10 centimeters. Thus, the area of the top surface of this wedge is,
[tex]A_{sector}=\dfrac{\pi (10)^2(45)}{360}\\A_{sector}\approx 39.3\rm\; cm^2[/tex]
Thus, the area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².

£200 is divided between Peter, Angad & Nick so that Peter gets twice as much as Angad, and Angad gets three times as much as Nick. How much does Angad get?
Let the amount Nick gets = x
Angad gets 3x ( 3 times as much as Nick)
Peter gets 6x (Twice as much as Angad)
Add together to equal the total amount:
x + 3x + 6x = 200
Simplify:
10x = 200
Divide both sides by 10:
x = 20
Angad gets 3x = 3(20) = 60

48 girls, 41 boys, and 5 teachers sat in the gym. Write the ratio of girls to boys in three ways.
A: 48 to 41, 41:5, 5/48
B: 41 to 48, 41:48, 41/48
C: 48 to 41, 48:41, 41/48
D: 48 to 41, 48:41, 48/41
Answer:
D
Step-by-step explanation:
The answer is D because the question is asking for girls to boys. So anything that has 5 in it is wrong because it isn't asking for teachers, which eliminates A. So since it is asking girls to boys the number order has to be 48 then 41 because it is asking for girls first then to boys. So that makes B wrong. When it comes to the fraction part of the ratio the first number it is asking for (which is girls) always goes on top. So that eliminates C which leaves only answer to be D.
