A father leaves his money to his four children the first received 1/3 the second received 1/6 and the third received 2/5 how muc

Eduardwww [97]

Answer:

The remaining child got a fraction of $\frac{1}{10}$ .

Step-by-step explanation:

Lets take the fraction of the money fourth child got is $x$

Addition of all these fractions should be equal to 1.

⇒ $\frac{1}{3} +\frac{1}{6} +\frac{2}{5} +x=1$

⇒ $\frac{10+5+12+30x}{30} =1$ (Taking a common denominator)

⇒ $\frac{27+30x}{30} =1$

⇒ $27+30x=30$

⇒ $30x=3$

⇒ $x=0.1$

Therefore,

The remaining child got a fraction of $\frac{1}{10}$ .

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet use 3.14 for pie

Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: $\frac{1}{3} *b*h$

$\frac{1}{3} *$ π $*r$ ² $*h$ =

$\frac{1}{3} *3.14*15^{2} *60=\\$

$\frac{1}{3} *3.14*225*60=$

$\frac{1}{3} *3.14*13,500=\\$

$\frac{13,500}{3} *3.14=\\$

$4500*3.14=$

14,130 feet³

liberstina [14]

Answer:

The length of the play area in feet is 1

Step-by-step explanation:

we know that

The perimeter of rectangle is given by the formula

$P=2(L+W)$

we have

$P=44\ yd\\W=21\ ft$

substitute

$44=2(L+21)$

solve for L

simplify

$22=L+21\\L=22-21\\L=1\ ft$
