Answer:

Step-by-step explanation:

6) In rectangle, diagonals are equal.

KM = LN

6x + 16 = 49

6x = 49 - 16

6x = 33

x = 33/6

x = 5.5

7) 2x + 4 =  5x - 11

2x - 5x = -11 -4

-3x = -15

x = -15/-3

x = 5

In  rhombus,diagonals make two congruent triangles

So, ∠ACD = ∠ACB

8) In Rectangle, diagonals are equal and bisect each other

x + 10 = 3x - 18

x - 3x =  -18 -10

-2x = -28

x = -28/-2

x = 14

9) a + 36 = 180   { sum of co interior angles is 180}

a = 180 - 36 = 144

a = 144

113 + b = 180    { sum of co interior angles is 180}

b = 180 - 113

b = 67

10)  4th figure

The Apple harvest produced 2,350kg of Apple's. A farmer packs 36 apples in the box. One apple weighs approximately 250 grams how
jenyasd209 [6]

Answer:

Step-by-step explanation:

The total number of apples produced at the apple harvest is 2,350kg.

1 kg = 1000 grams. Therefore,

2350 kg = 2350 × 1000 = 2350000kg

A farmer packs 36 apples in the box. If one apple weighs approximately 250 grams, the total weight of 36 apples would be

36 × 250 = 9000 grams

Therefore, the number of boxes that are needed to pack the apples would be

2350000/9000 = 261.11

It means that 262 boxes would be needed.

If θ=0rad at t=0s, what is the blade's angular position at t=20s
babunello [35]
The attached figure represents the relation between ω (rpm) and t (seconds)
To find the blade's angular position in radians ⇒ ω will be converted from (rpm) to (rad/s)
              ω = 250 (rpm) = 250 * (2π/60) = (25/3)π    rad/s
              ω = 100 (rpm) = 100 * (2π/60) = (10/3)π    rad/s

and from the figure it is clear that the operation is at constant speed but with variable levels
            ⇒   ω = dθ/dt   ⇒   dθ = ω dt

            ∴    θ = ∫₀²⁰  ω dt  
 
while ω is not fixed from (t = 0) to (t =20)
the integral will divided to 3 integrals as follow;
       ω = 0                                          from t = 0  to t = 5
       ω = 250 (rpm) = (25/3)π            from t = 5   to t = 15
       ω = 100 (rpm) = (10/3)π            from t = 15 to t = 20

∴ θ = ∫₀⁵  (0) dt   + ∫₅¹⁵  (25/3)π dt + ∫₁₅²⁰  (10/3)π dt
     
the first integral = 0
the second integral = (25/3)π t = (25/3)π (15-5) = (250/3)π
the third integral = (10/3)π t = (25/3)π (20-15) = (50/3)π

∴ θ = 0 + (250/3)π + (50/3)π = 100 π

while the complete revolution = 2π
so instantaneously at t = 20
∴ θ = 100 π - 50 * 2 π = 0 rad

Which mean:
the blade will be at zero position making no of revolution = (100π)/(2π) = 50

Find the value of 21.03 + 80.4 - 21.03 ​
astraxan [27]

Answer:

80.4

Step-by-step explanation:

21.03 + 80.4 - 21.03

21.03 - 21.03  cancel each other out because it equals 0.

The equation becomes 0 + 80.4 = 80.4
