I'll give u the answer n u decide it..
(1) 10p coins : 50p coins
         5           :  2
          ?          :  6 
   6/2 =3 so...5 x 3 = 15..
the answer is 15.

(2) a) 3 : 8
      b) 3 : 5

(3) 15+6 = 21, so 4200/21 = 200
      matt  get 15 so its 15 x 200 = 3000
      amber get 6, so its 6 x 200 = 1200

(4) red : yellow : blue
       5   :   2       :    3
       ?   :    ?      :   21
so divide 3 with 21 the ans will be 7..

a) 5 x 7 + 35
b) red + yellow + blue
    = 35 + ? +21
   yellow =7 x 2 + 14
so the final answer fo question b) is 35+ 14 + 21 =70 sheeps

5)

I need the solving and the answer please <br> thank you
Lorico [155]

Answer:

Step-by-step explanation:

11x - 2° = 75° ( being corresponding angles )

11x = 75° + 2°

11x = 77°

x = 77°/ 11

x = 7°

hope it helps :)

Centered 7 meters above the ground, a Ferris wheel of radius 6 meters is rotating with angular speed 24 degrees per second.
borishaifa [10]
24 degrees per second is 360 degrees in 15 seconds (pretty fast for a Ferris wheel!).

a) The distance above the ground can be modeled using a cosine function.
.. h(t) = 7 -6cos(2πt/15)


b) h(t) = 10
.. 10 = 7 -6cos(2πt/15)
.. (10 -7)/-6 = cos(2πt/15)
.. 2πt/15 = π ±π/3 +2kπ
. t = 7.5*((1 ±1/3) +2k) . . . . . . . . seconds; k = any integer

You are 10 meters above the ground at t=5 seconds and every 15 seconds thereafter, as well as at t=10 seconds and every 15 seconds thereafter.

Given the system
wariber [46]

Answer:

1.Therefore the solution of given system is (3,4)

2.Therefore the solution of given system is (-1,2)

Step-by-step explanation:

1.

Given the system

2x +3y =18...........(1)

-2x+5y =14...........(2)

Adding the equation (1) and (2)

2x+3y-2x+5y= 18+14

⇔8y = 32

⇔y = \frac{32}{8}

⇔y = 4

Putting the value of y in equation (1)

2x + 3. 4=18

⇔2x+12 =18

⇔2x = 18-12

⇔2x = 6

⇔x =3

Therefore the solution of given system is (3,4)

2.

Given the system

3x +4y = 5..........(a)

2x +7y =12...........(b)

Equation (a) ×2 - equation (b)×3

2(3x+4y)- 3(2x+7y) = 2.5 -12.3

⇔6x + 8y -6x -21y = 10-36

⇔ -13y = -26

⇔y=\frac{-26}{-13}

⇔y = 2

Putting the value of y in equation (a)

3x +4.2 =5

⇔3x = 5 -8

⇔3x = -3

⇔x = -1

Therefore the solution of given system is (-1,2)
