Answer:

Step One

Calculate the area of both the skating area and the spectator area.

Area = L * W

L = 4x

W = 4x

Area = 4x * 4x

Area = 16x^2

Step Two.

Find the radius of the semicircle. R = radius

From the diagram

R = The full length - the length given in the red shaded area.

R = 4x - 2x

R = 2x

Step Three

Find the area of the semicircle.

Area of a full circle = pi R^2

Area of a 1/2 circle = [tex]\frac{\pi *(2x)^2}{2}[/tex]

Area of a 1/2 circle = [tex]\frac{\pi *4*x^2}{2}[/tex]

Area of a 1/2 circle = [tex]\frac{\pi *2*x^2}{}[/tex]

Notice that the 2 in the denominator cancels in part with the 4 in the numerator.

Step Four

Find the area of the shaded area

Area of the shaded Area = Whole Area - Area of the Semi Circle.

Area of the shaded Area = 16x² - [tex]\frac{\pi *2*x^2}{}[/tex]

Answer:

x= 1.5 y= 2.5

Step-by-step explanation:

(-1.5,2.5) is  the ordered pair for point A.

A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

We have to find the ordered pair of point A.

As we observe the given graph.

The points A lies in the second quadrant.

The x axis value in second quadrant will be in negative.

The y value in second quadrant is positive.

The point A is 2.5 units away from the x axis and -1.5 units from the y axis.

So the ordered pair of A is (-1.5,2.5)

Hence, (-1.5,2.5) is  the ordered pair for point A.

Answer:

20 books

Step-by-step explanation:

20% is 1/5 of 100% so the other 4/5 would be 4 times 5 which equals 20 books it total

Answer:

Mr. Brown bought 20 books.

Step-by-step explanation:

20% times 5 would be 100%. Since Mr. Brown bought 4 books, and that was 20% of all the books he bought, you would have to multiply the number of paper back books by 5 to get the answer of 100% of all books he bought, which would be 20. This problem would look like this 20(5) = 4(5), 100% = 20 books.

Answer:

The 8th term of the following sequence is 9375.

Step-by-step explanation:

Given the sequence

3/25, 3/5, 3, 15

As we know that a geometric sequence has a constant ratio and is defined by:

[tex]\:a_n=a_0\cdot r^{n-1}[/tex]

so

[tex]\frac{3}{25},\:\frac{3}{5},\:3,\:15[/tex]

[tex]\frac{\frac{3}{5}}{\frac{3}{25}}=5,\:\quad \frac{3}{\frac{3}{5}}=5,\:\quad \frac{15}{3}=5[/tex]

As the ratio 'r' is the same.

so

[tex]r=5[/tex]

As the first element of the sequence is

[tex]a_1=\frac{3}{25}[/tex]

Therefore, the nth term is computed by

[tex]\:a_n=a_0\cdot r^{n-1}[/tex]

[tex]a_n=\frac{3}{25}\cdot \:5^{n-1}[/tex]

Putting n = 8 to determine the 8th term.

[tex]a_8=5^7\cdot \frac{3}{25}[/tex]

[tex]a_8=\frac{3\cdot \:5^7}{25}[/tex]

    [tex]=\frac{5^7\cdot \:3}{5^2}[/tex]

     [tex]=5^5\cdot \:3[/tex]

     [tex]=9375[/tex]

Therefore, the 8th term of the following sequence is 9375.

Answer:

40ft^2

Step-by-step explanation:

Hello There!

In this problem since we know that these are similar triangles we can set up a ratio in order to solve for the missing leg lenght, and then the areas.

This can be done by using the ratios and solving for x:

[tex]\frac{8ft}{12ft}[/tex]  x  [tex]\frac{4ft}{x}[/tex]

After this is done we find that the missing leg on the larger triangle is equal to roughly 6. With this in mind we find the area of the two triangles by multiplying the legs and dividing by 2, respectively.

The larger triangle will have an area of 72ft^2

the smaller triangle will have an area of 32ft^2

in order to find the difference in area we will simply subtract the two and find that the difference is equal to 40ft^2

Hope this helps

Answer:

50

Step-by-step explanation:

let <LPM be x

60+70+x=180 (sum of angle in triangle is 180)

x=50

<LPM=<KPN (being vertically opposite angle)

<KPN= 50

Answer:

Step-by-step explanation:

in triangle MPL

60 + 70 +AngleMPL=180(Angle sum property)

Angle MPL = 180 -60-70 = 50°

Angle NPK = AngleMPL

Angle NPK = 50°

Answer:

The value of x is 15 cm

Step-by-step explanation:

#(d)

In Δ BDC

∵ ∠D is a right angle

∴ BC is the hypotenuse

∴ BD and DC are the legs of the right angle

→ By using Pythagoras Theorem

∵ (BC)² = (BD)² + (DC)²

∵ BD = 10 cm

∵ DC = 2√11 cm

→ Substitute them in the equation above

∴ (BC)² = (10)² +(2√11)² = 100 + 44 = 144

→ Take √  for both sides

∴ BC = 12 cm

In Δ ABC

∵ ∠B is a right angle

∴ AC is the hypotenuse

∴ AB and BC are the legs of the right angle

→ By using Pythagoras Theorem

∵ (AC)² = (AB)² + (BC)²

∵ AB = 9 cm

∵ BC = 12 cm

∵ AC = x

→ Substitute them in the equation above

∴ x² = (9)² +(12)² = 81 + 144 = 225

→ Take √  for both sides

∴ x = 15 cm

∴ The value of x is 15 cm

its the second option since there are 4 circles and 2 oval things.

Answer:

C. [tex] y + 2 = -3(x - 1) [/tex]

Step-by-step explanation:

All we need to create an equation of the given graph is a point on the line (x1, y1) and the slope (m) of the line.

Thus, equation of in point-slope form is given as [tex] y - y_1 = m(x - x_1) [/tex].

Finding the slope (m) of the line of the graph given, using points (0, 1) and (1, -2).

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 1}{1 - 0} = \frac{-3}{1} = -3 [/tex]

Substitute (x1, y1) = (1, -2) and m = -3 into [tex] y - y_1 = m(x - x_1) [/tex]

[tex] y - (-2) = -3(x - 1) [/tex]

[tex] y + 2 = -3(x - 1) [/tex]

The answer is C.

Answer:

all of them except straight and reflex

Step-by-step explanation:

when angles are supplementary it means that they add up to 180

an acute angle is supplementary to an obtuse angle

an obtuse angle is supplementary to an acute angle

a right angle is supplementary to a right angle

but a reflex angle is over 180 so it's not supplementary to anything

and a straight angle is already 180 so it has no supplements either
