Answer:

\huge{ \fbox{ \sf{41}}}

Step-by-step explanation:

\star{ \sf{ \: Let \: the \: missing \: number \: be \: x}}

Create an equation

\sf{x + ( - 16) = 25}

\mapsto{ \sf{x  - 16 = 25}}

Move 16 to right hand side and change it's sign

\mapsto{ \sf{x = 25 + 16}}

Add the numbers : 25 and 16

\mapsto{ \sf{x = 41}}

The number is 41

Hope I helped!

Best regards! :D

Pls help me with this and an explanation
SCORPION-xisa [38]

Answer:

The relationship in this equation is linear, but not proportional. If it was proportional, then replacing x with nx should give ny as the answer. Example:

y = 3x

Replace x with 2x.

y' = 3(2x) = 2(3x) = 2y

y' = 2y

This is proportional. But if you replace x with 2x in

y = 3x + 5,

you will not get 2y for y'. This case is not proportiona

A sector has angle 2.5 radians and perimeter of 18cm. find the radius of the sector
babunello [35]

Answer:

4 cm

Step-by-step explanation:

Perimeter = 18cm

θ = 2.5 radian

s = rθ, s = Arc length

Perimeter of Sector, P = arc length, s + 2r

Perimeter = rθ + 2r

r = Radius

18cm = r(2.5) + 2r

18cm = 2.5r + 2r

18cm = 4.5r

r = 18 /4.5

r = 4
