Answer:
17
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 = 8^2 = 64
b^2 = 15^2 = 225
64 + 225 = 289
c^2 = 289
c = Square root of 278
c = 17
If you square a number then get the square root of that, you end up with the original number.
Answer:
Step-by-step explanation:
f(x) = √16x
f(x) = 3/8 √9x
f(x) = 6/5 √x
Answer:
<h2>y = 75 when x = 60</h2>
Step-by-step explanation:
To solve this, we will use a proportion, since x and y vary directly with each other.
16 / 20 = 60 / y
<h2>Step 1: Cross-Multiply</h2>
16y = 1200
<h2>Step 2: Divide both sides by 16</h2>
16y / 16 = 1200 / 16
y = 75
<h2>Step 3: Check</h2>
16 / 20 = 60 / 75
1200 = 1200 ✅
<h2>y = 75 when x = 60</h2>
