A family of 2 adults and 3 children went on holiday to Miami.
oksano4ka [1.4K]

Answer:

£175

Step-by-step explanation:

Given the exchange rate was £1 = 1.84 dollars.

We are to change 322 dollars to pounds (£).

£1 = 1.84 dollars.

x = 322 dollars

Cross multiply

1.84 * x = 322

1.84x = 322

x = 322/1.84

x = 175

Hence 322 dollars in pounds will be £175

Find the cosine of the angle between the planes x+y+z=0 and 4x+3y+z=1.<br><br> Answer: cosθ=
marta [7]

The angle between the planes is the same as the angle between their normal vectors, which are

<em>n</em><em>₁</em> = ⟨1, 1, 1⟩

<em>n</em><em>₂</em> = ⟨4, 3, 1⟩

The angle <em>θ</em> between the vectors is such that

⟨1, 1, 1⟩ • ⟨4, 3, 1⟩ = ||⟨1, 1, 1⟩|| ||⟨4, 3, 1⟩|| cos(<em>θ</em>)

Solve for cos(<em>θ</em>) :

4 + 3 + 1 = √(1² + 1² + 1²) √(4² + 3² + 1²) cos(<em>θ</em>)

8 = √3 √26 cos(<em>θ</em>)

cos(<em>θ</em>) = 8/√78

Please help! this is kind of easy
solniwko [45]

Answer:

1st integer=x

2nd integer=x+1

3rd integer=x+2

4th integer=x+3

 

2(x +(x+2))= 3(x+1) +11

 

solve

 

2 (2x +2) = 3x + 3 + 11

 

4x + 4     = 3x + 14

 

-3x-4       =-3x -4

 

 

           x=10

 

1st integer=10

2nd integer=11

3rd integer=12

4th integer=13

Step-by-step explanation:
