Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
Answer:
a = 4

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
a is a leg
b is another leg
c is the hypotenuse<u>
</u> Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = <em>a</em>
Leg <em>b</em> = 3
Hypotenuse <em>c</em> = 5
<u>Step 2: Solve for </u><em><u>a</u></em>
Substitute in variables [Pythagorean Theorem]: a² + 3² = 5² [Subtraction Property of Equality] Isolate <em>a </em>term: a² = 5² - 3² Evaluate exponents: a² = 25 - 9 Subtract: a² = 16 [Equality Property] Isolate <em>a</em>: a = ±4 Since we are dealing with a regular right triangle and not a quadrant triangle, we use the positive root.
∴ a = 4

<u>Solve y:</u>
3/5 = y/(y+ 3)
3(y + 3) = 5y
3y + 9 = 5y
2y = 9
y = 4.5
.
Answer: y = 4.5
I think it would be 19 because if you take 100-5 it would be 95 and divide 95 by 19 you would get 5 so each student got 5 cookies and there was 19 students
