Answer:
For your area models you would draw two rectangles and divide one into 2 equal sections, and the other one with 8 equal sections. You then shade 1 box out of the first triangle with 2 equal sides. Then you would shade 7 boxes on the rectangle with 8 equal sides. These diagrams would show you that 7/8 and 1/2 are not equivalent.
To find out what fractions are equivalent to 1/2 you would take 1/2 and times the numerator and denominator by the same number.
1/2*2/2= 2/4
2/4=1/2
1/2*9/9= 9/18
9/18=1/2
2/4 and 9/18 both equal 1/2
Hope this helps ;)

Answer: Choice D. 8m, 9m, 10m</h3>
==================================
Explanation:
If a = 8 and b = 9 are the two legs of a triangle and c = 10 is the hypotenuse, then
a^2 + b^2 = c^2
8^2 + 9^2 = 10^2
64 + 81 = 100
145 = 100
We get a false equation as 145 and 100 are two different values. So the original equation is false when (a,b,c) = (8,9,10)
By the converse of the pythagorean theorem, we have proven that this particular triangle is not a right triangle
-------------
Contrast this with something like choice A where we have a = 3, b = 4, c = 5 leading to
a^2 + b^2 = c^2
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
we get a true equation so a triangle with sides 3,4,5 is a right triangle. Choices B and C follow a similar path.
Answer:
50 computers
Step-by-step explanation:
After reduction, he bought x computers hence price per unit was 1800000/x
Before reduction, price per unit was 1800000/(x-5)
The difference in the price is 4000 hence
Therefore, x=50
