Quadrilateral ABCD is inscribed in this circle
B
What is the measure of /A?
Enter your answer in the box
Answer:
Here,
x+2+3x+6 = 180 [ Sum of opposite angle of cyclic quadrilateral is Supplementary ]4x + 8 = 180 4x = 180 - 8x = 172/4x = 43Now,
Angle A = 3 * 43 + 6= 129 + 6= 135
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

What is the quotient? startfraction 2 m 4 over 8 endfraction divided by startfraction m 2 over 6 endfraction
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) )
= (m + 2)/4 x 6/(m + 2)
= 6/4
= 3/2

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
You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes to get to school measured in
minutes, is modeled using the function g(x) = x - 3x + 4x - 5, where x is the number of stops the bus makes. If the bus makes 2 stops after you board, how
long does it take you to get to school?
AA. 1 minute
B. 3 minutes
C. 7 minutes
D. 11 minutes
Answer:
-1
Step-by-step explanation:
g(2) = (2) - 3(2) + 4(2) - 5
g(2) = 2 - 6 + 8 - 5
g(2) = 2 - 6 + 3
g(2) = 2 - 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.
