The correct question is
The raised vegetable garden in Susan's yard is in the shape of a rectangular prism with a volume of 48 cubic feet and a height of 3/4 foot. The base of the rectangular prism is not a square and the width is greater than 2 feet. What is the length and width of the rectangular prism?

let
x-------> the length of the base of the rectangular prism
y-------> the width of the base of the rectangular prism

we know that
volume of the prism=area of the base*height
volume=48 ft³
height of the prism=3/4 ft

area of the base=volume/height--------> 48/(3/4)---> 48*4/3----> 64 ft²

area of the base=64 ft²
area of the base=x*y
64=x*y--------> equation 1

y=x+2--------> equation 2

substitute equation 2 in equation 1
64=x*[x+2]-----> 64=x²+2x------> x²+2x-64=0

using a graph tool----> to resolve the second order equation
see the attached figure

the solution is
x=7.062 ft
y=x+2-----> y=7.062+2-----> y=9.062 ft

the answer is
the length of the base of the rectangular prism is 7.062 ft
the width of the base of the rectangular prism is 9.062 ft

B/G = 4/5

8/G = 4/5 Multiply each side by 5

40/G = 4 Multiply each side by G

40 = 4G Divide each side by 4

G = 10

There are 10 girls in the class.

Check:

8/10 = 4/5

4/5 = 4/5

A bag contains 20 marbles. These marbles are identical, except they are labeled with the integers 1 through 20. Five marbles are

faust18 [17]

Answer:

a. The probability of getting an specific sequence would be

$(1/20)*(1/19)*(1/18)*(1/17)*(1/16)$

b. The probability of having an specific sequence would be.

$5/20 = 1/4$

Step-by-step explanation:

a. If you draw 5 marbles without replacement, the probability of getting an specific sequence would be

$(1/20)*(1/19)*(1/18)*(1/17)*(1/16)$

b. If you draw 5 marbles all at once without replacement, the probability of having an specific sequence would be.

$5/20 = 1/4$

Need help with this problem

icang [17]

Okay we'll start easy
46*93
We will take 6*3 which is 18.
40*3 which is 120
6*90 which is 540
40*90 which is 3600
Now add up those
18+120+540+3600 which is 4278

So the missing numbers.

3._00 is going to be 3600
5_0 is going to be 540
_20 is going to be 120
1_ is going to be 18
4._78 is going to be 4.278
Hope this helped. ^~^
