Answer:

<h3>\frac{4}{\sqrt{7}}-1+\frac{2}{\sqrt{7}}+1</h3>

=\frac{4}{\sqrt{7}}+\frac{2}{\sqrt{7}}-1+1

\frac{4}{\sqrt{7}}+\frac{2}{\sqrt{7}}=\frac{6\sqrt{7}}{7}

\frac{6\sqrt{7}}{7}-1+1

-1+1=0

=\frac{6\sqrt{7}}{7}

Work out 1 3/4 x 4 1/6
sattari [20]

Convert mixed number to improper fraction:

1\dfrac{3}{4}=\dfrac{1\cdot4+3}{4}=\dfrac{4+3}{4}=\dfrac{7}{4}\\\\4\dfrac{1}{6}=\dfrac{4\cdot6+1}{6}=\dfrac{24+1}{6}=\dfrac{25}{6}\\\\1\dfrac{3}{4}\times4\dfrac{1}{6}=\dfrac{7}{4}\times\dfrac{25}{6}=\dfrac{7\times25}{4\times6}=\dfrac{175}{24}=\dfrac{168+7}{24}=7\dfrac{7}{24}

Volume of cylinder can be calculated by using the formula V= pir^2h

Where r is radius of cylinder and h is the height.

A cylinder with radius 1 inch and height of 1 inch is given.

r=1,h=1,π=3.14.

Substituting the given values :

V=3.14(1)^2(1)

Volume of cylinder rounded to nearest tenth is 3.14 cubic inches .

C an anyone solve this 3(2b + 3)2 = 36<br> and if so what is it
Natali [406]
3(2b + 3)^2 = 36

Divide by 3 on both sides:
(2b + 3)^2 = 12

Square root both sides:
2b + 3=  \pm \sqrt{12}

Take away 3 from both sides:
2b= \pm \sqrt{12} - 3

Divide by 2 on both sides:
b=  \dfrac{ \sqrt{12} -3 }{2}  \ or \ b=  \dfrac{ -\sqrt{12} -3 }{2}

Answer:
b=  0.23 \ or \ -3.23
