Answer:
530 m²
Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530

Julie wants to randomly choose two out of three friends, Margarite, Anita, and Sasha, to go with her to a
concert. In which method does one of Julie's friends have more than a fair chance of being chosen?
Slip system can be used to give more than fair chances of selection where the number of slips for one is more than the other.
There are multiple ways of selecting random sample like tossing a coin, flipping a die, lottery system.
Describing a method which can be used to provide more than a fair chance of selection is as follows:
Julie has 3 friends, so make the total number of slips say n
where n is not a multiple of 3.
If n is not a multiple of 3 then her 3 friends will not get an equal chance of being selected.
Consider n=5
She has 3 friends, so 2 slips has repeated names, thus creating more chance of being selected than the one who has name only on one slip.
Thus, this method may result in more chance of selection of one over other.

2) Suppose a certain type of bacteria reproduces continuously at a rate of 25% per minute. If the initial
amount of bacteria is 27.
a) Write an equation for the growth of bacteria over time.
b) How money bacteria will there be in 5 minutes? 1 hour?
c) How long will it take for the bacteria to reach a population of 10,000?
A) The equation for the growth of bacteria over time is : n(t) = 27( [tex]e^{25t}[/tex])
B) The number of bacteria the would be in 5 minutes 1 hour is :
n(5mins) = 215.055 , n(1) = 1944132282109.422
C) The time it will take for the bacteria to reach a population of 10,000 is : t = 0.237 hours
Determine the Equation, number of bacteria and time takenApplying the mathematical growth and decay modelling
a. n(t) = [tex]n_{0}[/tex] [tex]e^{rt}[/tex]
[tex]n_{0}[/tex] = initial amount of bacterial
[tex]e^{rt}[/tex] = exponent
r = rate
t = time
n(t) = 27( [tex]e^{25t}[/tex])
b. for 5 minutes
converting 5 minutes to hours; we divide by 60 minutes
[tex]\frac{5}{60}[/tex] = 0.083 hour
n(5 mins) = 27( [tex]e^{25t}[/tex])
n(5 mins) = 27( [tex]e^{25 * 0.083}[/tex])
n(5 mins) = 27( [tex]e^{2.075}[/tex])
n(5mins) = 27( 7.965)
n(5mins) = 215.055
For 1 hour we have
n(1) = 27( [tex]e^{25t}[/tex])
n(1) = 27( [tex]e^{25 * 1}[/tex])
n(1) = 27( [tex]e^{25}[/tex])
n(1) = 27 * (72004899337.386)
n(1) = 1944132282109.422
c. How long will it take for the bacteria to reach a population of 10,000?
10000 = 27( [tex]e^{25t}[/tex])
[tex]\frac{10000}{27}[/tex] = ( [tex]e^{25t}[/tex])
370.370 = ( [tex]e^{25t}[/tex])
㏑ (370.370 ) = ㏑ ( [tex]e^{25t}[/tex])
5.915 = 25t
[tex]\frac{5.915}{25}[/tex] = t
t = 0.237 hours

The Quotients of the given expression (2m + 4) / 8 divided by (m + 2)/6 would be 3/2.
What are the Quotients?Quotients are the number that is obtained by dividing one number by another number.
Dividend ÷ Divisor = Quotients
(2m + 4) / 8 divided by (m + 2)/6
= (2m + 4) / 8 ÷ (m + 2)/6
= (2m + 4)/8 x (6 / (m + 2) )

3. Find the center of the circle that can be circumscribed about EFG with E(6,4), F(6,2), and G(10,2).
A. (6, 4)
B. (8,3)
C. (3,8)
D. (4,2)
Step-by-step explanation:
The general form of the equation of a circle is
(x-a)^2 + (y-b)^2 = r^2 where the center is (a,b)
Plugging in the given values:-
(6 - a)^2 + (4-b)^2 = r^2 and
(6-a)^2 + (2-b)^2 = r^2
Subtracting:-
(4-b)^2 - (2 - b)^2 = 0
16 - 8b + b^ - (4 -4b + b^2) = 0
12 - 4b = 0
-4b = -12
b = 3
Similarly if we take the 2 points (6,2) and G(10,2) and make two equations we can find the value of a
(6-a)^2 + (2-b)^2 = r^2
(10.a)^2 + (2-b)^2 = r^2 subtract::-
(6-a)^2 -(10-a(^2 = 0
this will give a = 8
so the center of the circle is the poit (8,3)

The label on a can starts 2.5 in below the lid. What
is the area of the label?
From the computation below, the area of the label is 707 Inches.
This calculation is carried out using the theorem of the area of curved shapes.
What is the Curved Surface Area of a Cylinder?The formula for the Curved Surface Area of a Cylinder is given as:
2 [tex]\pi[/tex] rh
= 2 [tex]\pi[/tex] x 7.5 x 15.
This assumes that the label also ends at an equal distance from the top of the lid. Hence 15in = 20 - (2.5 x2);
Recall that [tex]\pi[/tex] = 22/7, hence
= 2 x (22/7) x 7.5 x 15
= 707.142857143
Approximately, this equals; 707 Inches.
Hence, the area of the label = 707 inches.
Notice that the question is incomplete. From inference, however, the general calculation above contains the principles for calculating the area of a label.
