Answer:
540x+680y<=20000
Step-by-step explanation:
x will be the number of laptops. Since they are $540 each, 540x is the amount spent on laptops, depending on how many (x) are purchased.
y will be the number if desktops. Since they are $680 each, 680y is the amount spent on desktops, depending on how many (y) are purchased.
Adding all the money spent on laptops and desktops, we get
540x + 680y. This amount must be less than the $20000. It can be exactly $20000 also. But it cannot be more than $20000.
540x+680y<=20000
I think it would be true because they are crossing
Answer:
171.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·10+5·10+5·10+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈171.65064
3/4 or 0.75 hope this helps :)
Hey there!
In this scenario, we are given the area of the rug. It is asking for the diameter, the distance across the rug. The area is the radius (half of diameter) squared times pi (we will use 3.14).
First, we need to undo the area and find the radius.
78.5/3.14=25
√25=5
Since the diameter is twice the radius, we multiply or radius by two.
5*2=10
Therefore, our edge is 10 feet from one edge to the other.
I hope this helps!
