Which is greater 9,000 cm or 2 km

Mathematics
1 answer:
Mandarinka [93]3 years ago
5 0
9000 centimeters is less than 2 kilometers. 100 centimeters is equal to 1 meter while 1000 meters is equal to 1 kilometer. So, 9000 cm would equal 90 meters which would only equal 0.09 kilometers.
In other words:
100 cm = 1 m
1000 m = 1 km
So, 9000 cm = 90 m = 0.09 km

9000 cm < 2 km

if the area of a rectangle is represented by 25x^3y^6 and its width is represented by 10xy, express the length of the rectangle
iren [92.7K]

The length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is <u>2.5x²y⁵</u>.

The area of a figure is the total space enclosed in two dimensions within its boundary.

The area of a rectangle is given as, area = length*width.

In the question, we are given that the area of a rectangle is represented by 25x³y⁶ and its width is represented by 10xy, and are asked to express the length of this rectangle in terms of x and y.

We know that the area of a rectangle is given as, area = length*width.

Substituting the known values in the equation, we get:

25x³y⁶ = length*10xy.

Rearranging this equation, we get:

length = 25x³y⁶/10xy = (5x²y⁵)/2 = 2.5x²y⁵.

Thus, the length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is <u>2.5x²y⁵</u>.

If f(x)= 2x2-4x and g(x)=5-2x evalute f(x)-g(x) for x=5
dezoksy [38]
<span>f(x)= 2x²-4x
</span><span>g(x)= 5-2x

</span> f(x)-g(x) = 2x²-4x - ( 5-2x) = 2x² - 4x-5+2x= 2x² -2x-5
f(x)-g(x) = 2x² -2x-5
f(5)-g(5) = 2*5² -2*5-5=50-10-5 =35
f(5)-g(5) = 35
