The length of a rectangle is twice its width. Find its area, if its perimeter is 7 1/3 cm The area of the rectangle is _sq. cm.

Harman [31]

Answer:

The area of rectangle is $2\frac{80}{81}\ cm^2$

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

we have

$P=7\frac{1}{3}\ cm=7+\frac{1}{3}=\frac{22}{3}\ cm$

so

$\frac{22}{3}=2(L+W)$

$\frac{11}{3}=(L+W)$ ----> equation A

Remember that

The length of a rectangle is twice its width.

so

$L=2W$ ----> equation B

substitute equation B in equation A

$\frac{11}{3}=(2W+W)$

solve for W

$W=\frac{11}{9}\ cm$

Find the value of L

$L=2(\frac{11}{9})$

$L=\frac{22}{9}\ cm$

Find the area of rectangle

$A=LW$

substitute the values

$A=(\frac{22}{9})(\frac{11}{9})$

$A=\frac{242}{81}\ cm^2$

Convert to mixed number

$\frac{242}{81}\ cm^2=\frac{162}{81}+\frac{80}{81}=2\frac{80}{81}\ cm^2$

A carousel has 30 cars. Determine the angle of rotation that maps #6 to car #19.

ivolga24 [154]

Answer: The answer is 260°.

Step-by-step explanation: Given that a Carousel has 30 cars. We need to find the angle of rotation which maps car no. 6 to car no. 19.

Now, the Carousel will make a regular polygon with 30 sides and each car as a vertex.

So, angle of symmetry for the polygon is

$\theta=\dfrac{360^\circ}{30}=20^\circ.$

Number of sides from car 6 to car 19 = 19 - 6 = 13.

Therefore, the angle of rotation that maps car 6 to car 19 is given by

$\alpha=13\times \theta=13\times 20^\circ=260^\circ.$

Thus, the required angle of rotation is 260^\circ.

Find the probability of having 2,3, or 4 successes in five trials of a binomial experiment in which the probability of success i

DiKsa [7]

0.45033504848

Explanation:

The binomial formula is given by
nCk⋅ρk(1−ρ)n−k thus the result for x would be

p(x=2)=(5!(5−2!)2!)(.4)2(1−.4)5−2=0.3456

p(x=3)=(5!(5−3!)3!)(.4)3(1−.4)5−3=0.13824

p(x=4)=(5!(5−4!)4!)(.4)4(1−.4)5−4=0.027648

p(a∪b∪c)=p(a)+p(b)+p(c)−p(a)⋅p(b)−p(a)⋅p(c)−p(b)⋅p(c)=.3456+.13824+.027648−.047775744−.0095551488−0.00382205952

p(a∪b∪c)=0.45033504848
