Mnenie [13.5K]

Answer:

the scale is 630:1 = 0.16%

80inch^2 of 50400inch^2 however = 0.16%

Step-by-step explanation:

350ft^2 = 50400inches 8 x 10 = 80inches = 50400/80 = 630

50400/9 =5600 we distribute

5600/80 = 7

showing us that 7 x 9 = 63 where 63 x 80 = 5040 1/100th

1 = 630

7x9x 80 = 1/100 of 50400

0.01589 x 7x9x80x 7x9x80 = 80

Proves that every every 10000 the percentage goes down 0.00011%

Deidre is picking out some movies to rent, and she is primarily interested in documentaries and children's movies. She has narro
exis [7]

Answer: 6630

Step-by-step explanation:

Given , Number of documentaries = 17

Number of children's movies = 20

Total movies = 17+20=37

Number of combinations of r things taken out of things = ^nC_r=\dfrac{n!}{r!(n-r)!}

Now, the number of different combinations of 3 movies can she rent if she wants at least one documentary

= (1 documentary+2 children's movies  , 2 documentary+1 children's movies , 3 documentary+0 children's movies)

=^{17}C_1\times^{20}C_{2}+^{17}C_2\times^{20}C_{1}+^{17}C_3\times^{20}C_{0}

=(17)\times\dfrac{20!}{2!18!}+\dfrac{17!}{2!15!}\times(20)+\dfrac{17!}{3!14!}(1)\\\\=3230+2720+680=6630

Hence, the  number of different combinations of 3 movies can she rent if she wants at least one documentary is 6630 .

Karolina [17]
There are 1,826 days in 5 yr. In relation to the leap year, there are 1826.25 days in 5 yrs. That is because there are really 365.25 days in a year (making every four years a leap year). So, when you multiply 365.25 by 5, you get 1826.25.

A square plot of land has an area of 484m².What is the perimeter​
harina [27]

Answer:

Perimeter: 88m

Step-by-step explanation:

Area of the square plot = (Side) X (Side)

And we are given the area is 484m²,

therefore, (Side) X (Side) = 484m²

or,

(Side)² = 484, taking square root on both the sides,

\sqrt{(Side)^{2} } = \sqrt{484}

Side = 22m.

And we know that, perimeter of a square is = 4 X (Side)

Therefore, Perimeter = 4 X 22 = 88m
