1/4=a
2/5=b
4/10=2/5=b
25/100=1/4=a
Good Luck
Answer: A
Step-by-step explanation: this was on my test so here is the answer
The <u>correct answer</u> is:
20 feet.
Explanation:
48 ft would be the measurement of the base of the right triangle formed by the flagpole and the ground. We are trying to find the height of the flagpole, which is the other leg of this right triangle.
The measurements we have for the second triangle are 5 and 12. Since she is 12 feet away from the mirror, the base of the triangle is 12. Her eye level is at 5 feet, so this is the height of the triangle.
Since we know these triangles are similar, we can use proportions to solve this. 48 is to 12 (base is to base) as the unknown height is to 5 (height is to height):
48/12 = x/5
Cross multiply:
48*5 = 12*x
240 = 12x
Divide both sides by 12:
240/12 = 12x/12
20 = x
The unknown height is 20 feet.
The correct answer to this question is <span>12.25 sq inches.

The largest rectangle is a square.
So if you divide 14" by 4 then you get 4 3.5" sides.
Area of a rectangle = L*W
<span>Area of a rectangle = 3.5 * 3.5</span>
<span>Area of a rectagle = 12.25 sq inches</span>
Isosceles triangle is a triangle which has at least two of it's sides equal to each other.
<u>Explanation:</u>
In geometry, an isosceles triangle is a triangle that has two sides of equivalent length. Here and there it is determined as having precisely different sides of equivalent length, and at times as having at any rate different sides of equivalent length, the last form subsequently including the symmetrical triangle as an extraordinary case.
An isosceles triangle is a triangle with (in any event) two equivalent sides. In the figure over, the two equivalent sides have length and the staying side has length. This property is equal to two points of the triangle being equivalent.
