<u><em>The correct question is</em></u>
Translate the sentence into an equation using n as the unknown number. Then solve the equation for n.
5 increased by half a number is 11
Let
n ----> the unknown number
we know that
The linear equation that represent this situation is
solve for n
Multiply by 2 both sides
subtract 10 both sides
Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length =
Area of the sector of a circle =
22). Arc length of the circle having central angle =
= 60°
Arc length =
=
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length =
= 12.5π
= 39.27 km
24). Central angle =
=
= 225°
Area of the sector =
= 43.20 yd²
25). Area of the sector =
= 65.97 yd²
