n+3n=20

4n=20

Divide both sides by 4

n=5

5+(3*5)=20

The product of 1 1/2 and 2 is
Over [174]

Method 1:

Convert the mixed number to the improper fraction:

1\dfrac{1}{2}=\dfrac{1\cdot2+1}{2}=\dfrac{3}{2}

Make the product:

1\dfrac{1}{2}\cdot2=\dfrac{3}{2}\cdot2

<em>canceled 2</em>

=\dfrac{3}{\not2_1}\cdot\not2^1}=\boxed{3}

Method 2:

1\dfrac{1}{2}=1+\dfrac{1}{2}

1\dfrac{1}{2}\cdot2=\left(1+\dfrac{1}{2}\right)\cdot2

<em>use the distributive property a(b + c) = ab + ac</em>

(1)(2)+\left(\dfrac{1}{2}\right)(2)=2+1=\boxed{3}

Find the area of the shaded region. The radius of the large circle is 10 m. Round answer to the nearest hundredth.
vivado [14]

Answer:

hello the figure related to your question is missing attached below is the missing figure

answer : 157.08 m^2

Step-by-step explanation:

Calculate the area of the shaded area

= Area of the large circle - Areas of the small circles

= (( \frac{\pi }{4} ) * D^2) - 2(  ( \frac{\pi }{4} ) * d^2 )     given that the small circles are congruent

= (( \frac{\pi }{4} ) * 20^2 ) - 2 ( ( \frac{\pi }{4} ) * 10^2 )

= 314.16 - 157.08

= 157.08 m^2
