Answer:
x in (-oo:+oo)
x = n/m-k // - n/m-k
k-(n/m)+x = 0
k-(m^-1*n)+x = 0 // - k-(m^-1*n)
x = -(k-(m^-1*n))
x = m^-1*n-k
x = m^-1*n-k
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
The relation would be 3 = k*9 as there is a direct proportional relationship.
So k = 3/9 = 1/3 and we can write the relation as d = 1/3 t where d=distance and t = time.
So if we double the time t we have:-
d = 1/3 * 18
= 6 kilometers.
So the distance is doubled.
Ok so first you would create a proportion.
8/x=4/1. Next you cross multiply and divide,
1 • 8÷4=x. Ratios are fractions with the first number being the numerator and the second being the denominator. If you think of it this way, you just find an equivalent fraction. Your answer would be 8:2 because in your proportion x=2.
Answer:
51.9 cm²
Step-by-step explanation:
From the diagram attached,
Area of the white region(segment)(A) = Area minor sector- area of the triangle
A = (πr²∅/360°)-(1/2r²sin∅)............... Equation 1
Where r = radius of the circle, Ф = reflex angle formed at the center of the circle, π = pie
From the question,
Given: r = 7 cm, Ф = 150°
Constant: π = 22/7
Substitute these values into equation 1
A = [(22/7)×7²×150/360]-[(1/2)×7²×sin150]
A = 64.17-12.25
A = 51.92
A = 51.9 cm²
