56 divided by 40 is 1.4. Multiply that by 100 and you get 140.
This is the long way of doing it, but it's the way I've always done it.
Lets start with finding the volume of the pool
The formula for the volume of a rectangular prism is
V=l*w*h where l=length w=width and h=height
plug in the data we know
V=40*20*4
V=3200ft³
Now for the hot tub.
3200ft³*1/4=800ft³
Add the volumes together
3200+800=4000ft³
Answer=4000ft³
Answer:
(2, - 3)
Step-by-step explanation:
given the 2 equations
5x + 3y = 1 → (1)
7x + 3y = 5 → (2)
multiply all terms in (1) by - 1
- 5x - 3y = - 1 → (3)
add (2) and (3) term by term to eliminate the term in y
(7x - 5x) + (3y - 3y) = (5 - 1)
2x = 4 ( divide both sides by 2 )
x = 2
Substitute x = 2 in either (1) or (2) for corresponding value of y
(2) : 14 + 3y = 5 ( subtract 14 from both sides )
3y = - 9 ( divide both sides by 3 )
y = - 3
solution is (2, - 3)
The expression 5 hundred times 10 unit in standard form is 5000
<h3>How to express the number in standard form?</h3>
The number is given as:
5 hundred times 10 unit
Express hundred as 100.
So, we have:
5 hundred times 10 unit = 5 * 100 times 10 unit
Express unit as 1.
So, we have:
5 hundred times 10 unit = 5 * 100 times 10 * 1
Express times as *.
So, we have:
5 hundred times 10 unit = 5 * 100 * 10 * 1
Evaluate the products
5 hundred times 10 unit = 5000
Hence, 5 hundred times 10 unit in standard form is 5000
