Ratio of boys to girls= 17:3
number of people= 740
to find the number of boys out of 740 people, you have to add the ratio together and divide 740 by it. then multiply the answer by 17 because the ratio for boys is 17.
17+3=20
740÷20=37
37×17=629
answer= 629

Answer:
Therefore,
Step-by-step explanation:
Consider a Δ ABC with
m∠ A = 45°
m∠ C = 30°
AB = c = 5√2
To Find:
BC = a = ?
AC = c = ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.
We know in a Triangle Sine Rule Says that,
In Δ ABC,
substituting the given values we get
∴
Similarly for 'b',
Therefore,
Answer:
x=-2, the axis of symmetry is at -2
Step-by-step explanation:
For a quadratic function in standard form, y=ax^2+bx+c , the axis of symmetry is a vertical line x=−b/2a
y=x^2+4x-5
a=1
b=4
x=-4/2(1)
x=-4/2
x=-2
