Answer:
2.25
Step-by-step explanation:
Change the fraction so that the denominator is something that's a factor of 100
9/4 = x/100
9 x 25 = 225
-----------------------
4 x 25 = 100
225/100
Now divide to get your decimal
225/100 = 2.25
Answer:
The pythagorean theorem is a theorem which states that the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
Answer:
2. 20
Step-by-step explanation:
2. The distance from one base of the prism to the other base of the prism, d = 10 mm
The thickness of each triangle to be used to fill the prism, t = 0.5 mm
The number of triangles needed, <em>n</em>, is therefore;
Where;
<em>d </em>represents the distance between the bases of the prism, <em>t</em>, represents the thickness of each triangle, and <em>n</em> represents the number of triangles it would take to fill up the prism
Therefore;
The number of triangles it would take to fill up the prism, n = 20
Answer:
<em>The perimeter is c. 28 millimeters</em>
Step-by-step explanation:
<u>The Perimeter of a Square</u>
The perimeter of a square is the sum of all its side lengths. If the side length is L, then the perimeter is:
P = 4L
The diagonal of a square is the hypotenuse of a right triangle with both legs of length L.
Applying Pythagora's theorem, we find the length of the diagonal is:
We know the diagonal of a square is
We can find the side length L:
Simplifying:
L = 7 millimeters
Thus, the perimeter is:
P = 4*7 = 28
The perimeter is c. 28 millimeters
The expressions that result in a difference of 1/4 are; Choice C) 2\3 − 5\12 and Choice E) 1/2 − 1\4
For Choice A; 2\10 − 1\6
For Choice B; 3\4 − 1 4
For Choice C; 2/3 - 5/12
For Choice D;. 7\8 − 3\12
For Choice D; 1/2 − 1\4
In essence, the expressions that result in a difference of 1/4 are; Choice C) 2\3 − 5\12 and Choice E) 1/2 − 1\4
