40-10=30
Answer:
y = 3.4
Step-by-step explanation:
Given 2 secants and a tangent drawn to the circle from an external point then
The square of the measure of the tangent is equal to the product of the external part of the secant to the entire secant.
Using the secant with measure y + 11, then
y(y + 11) = 7²
y² + 11y = 49 ( subtract 49 from both sides )
y² + 11y - 49 = 0 ← in standard form
with a = 1, b = 11 and c = - 49
Using the quadratic formula to solve for y
y = ( - 11 ± ) / 2
= ( - 11 ± ) / 2
= ( - 11 ± ) / 2
y = or y =
y = - 14.4 or y = 3.4
However y > 0 ⇒ y = 3.4 ( nearest tenth )
$18.75 hours at $7.85 pet hour is exactly 1471875, moving the decimal 4 places to the left and round to the nearest penny is
$147.1875 Or $147.19
