Step-by-step explanation:

Answer: A = 198.6cm²

Step-by-step explanation: The figure includes two semi circles on both ends. These can be solved as a whole circle with a diameter of 10cm because each semi circle is 5cm.

r = 10/2= 5cm

Area of circle:

A = πr²

A = 3.142*5²

A = 3.142*25

A = 78.55

A = 78.6cm²

The remaining section of the shape is a rectangle with a length of 12cm.

To get this, you subtract 10 from 22 because each semi circle is 5cm which adds up to 10cm.

The rectangle has a width of 10cm.

Area of rectangle:

A = lw

A = 12*10 = 120cm²

The total area of the shape:

A = 120 + 78.6

A = 198.6cm²

Answer:

y = -4x+11

Step-by-step explanation:

x − 4 y + 1 = 0

x+1 = 4y

4y = x+1

y = 1/4x+1/4

pendiente de una recta perpendicular es el recíproco negativo

negative reciprocal 1/4x is -4x

y = -4x+1/4

Con la nueva pendiente, use la forma de intersección de la pendiente y el punto para calcular la intersección usando (2,3) :

y = mx + b or y = -4x+b

3 = -4(2) + b

3 = -8 + b

11 = b

b = 11

y = -4x+11

The population of the chicken after 15 years in 2036 will be 5177.

The exponential growth model is given by the equation, [tex]y=y_oe^{rt}[/tex], where y is the population after t years, y₀ is the initial population, r is the rate of growth, and t is the time.

As it is given that the initial chicken population in the year 2021 is 3750, while the rate at which the population is increasing is 2.15% annually.

A.) The exponential growth model to write an equation that estimates the population t years after 2021.

The exponential growth model can be written as,

[tex]y=y_oe^{rt}\\\\y=3750e^{0.0215t}[/tex]

B.) The population of the town in 2036,

As the population is increasing for the next 15 years(2036-2021). Therefore, The population of the town in 2036 can be written as,

[tex]y=3750e^{0.0215t}\\\\y=3750e^{0.0215\times 15}\\\\y= 5177.1558\approx 5177[/tex]

AD = 9

Step-by-step explanation:

Using Pythagoras' identity in right triangle ABD , then

AD² + BD² = AB² , substitute values

AD² + 12² = 15²

AD² + 144 = 225  ( subtract 144 from both sides )

AD² = 81 ( take square root of both sides )

AD = [tex]\sqrt{81}[/tex] = 9

The type of sampling that the teacher used is of the type: Option D: Convenience sampling

If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.

Sampling which is done by taking the main population divided in categories(called strata), then such sampling from stratas (sub-parts of the population) is called stratified sampling.

In this type of sampling, starting of the sampling is done randomly, but then rest of the samples are collected by an order. Like for example, first point is selected randomly, then all points are selected that they are equidistant from each other in the population.

The word "convenience" summarizes this sampling. It is done in a way that those values from population are sampled which are in convenience with the researcher. Like if some random picking is to be done from beads spread on the ground, then the researcher picking those beads which are closer to him.

So, the math teacher took the sample from a specific part of the whole twelfth class. That's a strata. But sampling was done "only" from 1 strata, which is useless as field trip's data should be taken from other parts of the population too where students might be interested to go for field trip. Thus, its a wrong method of sampling.

That's more of like convenience sampling instead of stratified, where the teacher preferred convenience instead of proper sampling (as the sampling she did is not showing any proper ideology that she might've followed).

Thus, the type of sampling that the teacher used is of the type: Option D: Convenience sampling

Your answer is 13 1/8

Step-by-step explanation:

V = lwh

V = 1 1/2 x 3 1/2 x 2 1/2

V = 13 1/8

Given that,

Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games.

Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining.

The attached figure shows the equation that Jorge had :

8.25-0.25x=9.75-0.75x

Subtract 9.75 to both sides

8.25-0.25x-9.75=9.75-0.75x-9.75

-1.5-0.25x=-0.75x

Add 0.25x to the both sides,

-1.5-0.25x+0.25x=-0.75x+0.25x

-1.5=-0.5x

⇒ x = 3

Jorge is incorrect at step 2 where he taken -0.25x to the RHS such that -0.75x+0.25x, he get 0.5x instead of (-0.5x). Hence, From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.

Answer:
12 adult tickets, 16 child tickets

Step-by-step explanation:

x is the amount of adult tickets
y is the amount of child tickets
----------------------------------------------------------

lets make 2 equations:
1)    x + y = 28
2)   8x + 5y = 176
----------------------------------------------------------

now we can substitute either x or y into the second equation so that we only have to deal with one variable at once.

x + y = 28
subtract y from each side:
x + y - y = 28 - y
which gives you:
x = 28 - y
-------------------------------------------------------

Then we plug that into the second equation, which will give us:

8(28 - y) + 5y = 176

now you want to expand 8(28 - y), so you use the distributive property.

8(28 - y) = 8*28 - 8*y = 224 - 8y

now that we have solved that, plug it back into the equation:

224 - 8y + 5y = 176

subtract 224 from each side:

224 - 8y + 5y - 224 = 176 -224

which gives us:
-3y = -48

now if you multiply each side by ( -1 ) you get:
3y = 48

now divide both sides by 3 and you get:
y = 48 / 3

48 / 3 is 16

y = 16
-------------------------------------------------------------------------------

now plug y = 16 into equation 1

equation 1 was x + y = 28

plug 16 in for y which gives us:

x + 16 = 28

subtract 16 from both sides

x + 16 - 16 = 28 - 16

Which finally gives us
x = 12
---------------------------------------------------------------------------------

Remember:
x is the amount of adult tickets
y is the amount of child tickets

x = 12 means that 12 adult tickets were sold
y = 16 means that 16 child tickets were sold

Explanation:

An equilateral triangle has three sides of the same length, which in turn means that the curved arc pieces AB, BC and AC are the same length (but longer than each side of the triangle).

Furthermore, it leads to the fact that we split a 360 degree circle into three equal portions of 360/3 = 120 degrees each.

Imagine we drew in the line segments AX, BX, and CX. This splits the circle into 3 equal pie slices. Central angle BXC is 120 degrees because of the earlier calculation done before.
