Answer:

51.89085

Step-by-step explanation:

area = 49pi

150/360 * 49pi = 64.14085

triangle area = 7 * sin(75 degrees) * 7 * cos(75 degrees) = 12.25

==> white region = 64.14085 - 12.25 = 51.89085

Answer:

smaller ∡ = 36°

larger ∡ = 144°

Step-by-step explanation:

1x + 4x = 180

5x = 180

x = 36

Step-by-step explanation:

4.5÷4= 1.125

so each time she goes around the rectangle she's covering 1.125 km and we seed the length is twice the breadth x+2x=1.125

so 1.125 / 3 to give x which is the breadth=0.375 x 2 is equal to 0.75 km or 750 m this is the length of the field

Step-by-step explanation:

The length of a rectangular field is twice it's breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. What is the length of the field?

The distance cover in 4 laps is 4.5 km, So one lap is 4.5/4 = 1.125 km.

Let the breadth of the field be B so the length will be L or 2B.

The perimeter of the field is 2L+2B or 4B+2B = 6B = 1.125, so B = 1.125/6 = 0.1875 km and the length is 2*0.1875 = 0.375 km.

Check: perimeter = 2*0.375 + 2*0.1875 = 1.125 km and 4 laps covers 4*1.125 = 4.5 km. correct.

The field is 375 m long.

Answer:

Horizontal distance = 0 m and 6 m

Step-by-step explanation:

Height of a rider in a roller coaster has been defined by the equation,

y = [tex]\frac{1}{3}x^{2}-2x+8[/tex]

Here x = rider's horizontal distance from the start of the ride

i). [tex]y=\frac{1}{3}x^{2}-2x+8[/tex]

      [tex]=\frac{1}{3}(x^{2}-6x+24)[/tex]

      [tex]=\frac{1}{3}[x^{2}-2(3x)+9-9+24][/tex]

      [tex]=\frac{1}{3}[(x^{2}-2(3x)+9)+15][/tex]

      [tex]=\frac{1}{3}[(x-3)^2+15][/tex]

      [tex]=\frac{1}{3}(x-3)^2+5[/tex]

ii). Since, the parabolic graph for the given equation opens upwards,

    Vertex of the parabola will be the lowest point of the rider on the roller coaster.

    From the equation,

    Vertex → (3, 5)

    Therefore, minimum height of the rider will be the y-coordinate of the vertex.

    Minimum height of the rider = 5 m

iii). If h = 8 m,

    [tex]8=\frac{1}{3}(x-3)^2+5[/tex]

    [tex]3=\frac{1}{3}(x-3)^2[/tex]

    (x - 3)² = 9

    x = 3 ± 3

    x = 0, 6 m

    Therefore, at 8 m height of the roller coaster, horizontal distance of the rider will be x = 0 and 6 m

Answer:

UV corresponds to RS.

[tex]\angle R[/tex] corresponds to [tex]\angle U[/tex]

Step-by-step explanation:

Given

[tex]\triangle SRQ[/tex] and [tex]\triangle VUT[/tex]

Transformation: Rigid

Required

Determine the true options

When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:

SR to VU, SQ to VT, RQ to UT

And the corresponding angles are:

<S to <V, <R to <U and <Q to <T

From the corresponding sides above, we have:

SR to VU

Rewrite:

RS to UV

Hence: (c) is correct

From the corresponding angles above, we have:

[tex]\angle R[/tex] to [tex]\angle U[/tex]

Hence:

(b) is correct

Answer:

y=-x-6

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=-1(x-(-1))

y+5=-(x+1)

y=-x-1-5

y=-x-6

Answer:

c = 16g

Step-by-step explanation:

g = 1/16 c

Multiply both sides by 16.

16g = c

c = 16g

Answer:

c = 16g

Step-by-step explanation:

g=1/16c

This is an algebric equation that requires you to multiply both sides by 16.

g × 16 = 1/16c × 16

16g = c

Answer:

6 pizza, 6 pasta

Step-by-step explanation:

Now from the question we can see that Mia has comparative advantage in Pasta production and Mario in Pizza production.

Now before they both specialized, Mia's production was 6 pizza, 6 pasta. Mario also was making 6 pasta, 6 pizza.

So in total both were making 12 pizza and 12 pasta.

After they had specialized, Mario's pizza production is 18 pizza and Mia's pasta production is 18 pasta.

So we have that mia is producing 6 more pizza, 18-12 = 6

and Mario is also producing 6 more pasta.

So there is net gain of 6 pizza and 6 pasta.

Answer:

44° , acute angle

Step-by-step explanation:

Given

y = 8x + 12 ← substitute x = 4

y = 8(4) + 12 = 32 + 12 = 44°

Since 44° < 90° then angle y is acute

Answer:

17m

Step-by-step explanation: Cut the triangle in half and place it over the other triangle creating a square. We know that one side is 3m so since all the sides of a square are equal 3 times 3 equals to 9. For the rectangle 2 times 4 is 8. So finally 8 plus 9 equals to 17. The area of the composite figure is 17m.
