Answer:
17
Step-by-step explanation:
21 - 4 = 17
Substitute values
The answer would be £20, you would turn this into a proportion and doing that you'd have 70/100=14/x(x being the full cost) then you cross multiply and doing so you get 1400=70x and 1400 divided by 70 equals 20, so your answer is £20
Answer:
Original price of the dress was $97.88
Step-by-step explanation:
40/100=39.15/d
0.4d=39.15
0.4d=39.15
d=39.15/0.4
d=97.88
Considering Reid ate 1/4 of the pie and Joe ate 1/3 of the pie, we have to bring this to their common denominator. In this case that is 12.
1/4 + 1/3 = ?
(1 * 3)/12 + (1*4)/12 =
3/12 + 4/12 =
(3 + 4)/12 =
7/12
But this is the amount of the pie that both Reid and Joe ate.
To calculate the remaining amount we have to imagine our pie was still whole (12/12)
and substract what they both ate (7/12):
12/12 - 7/12 = 5/12
Only 5/12 of the pie was left, a little less than half of it :)
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The principal value of sin⁻¹(1) is 90°.
<h3>What is Sine (Sinθ)?</h3>
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
The principal value of sin⁻¹(1) is,
θ = Sin⁻¹(1)
θ = 90°
Hence, the principal value of sin⁻¹(1) is 90°.
