Answer:
$22.5
Step-by-step explanation:
The original price is $30 and it's on sale for 25% off. Since 25% is a quarter of the total price, I divided 30÷4=7.5. $7.5 is 25% of $30, so 7.5 is the amount taken off the original price. To find what Daysi paid, I subtracted 30-7.5=22.5. $22.5 is the result after the 25% off, so Daysi paid $22.5.
<u><em>x=5/8 is the correct answer.</em></u><em> </em>First you had to simplify from both sides of equation, and it gave us, . Then you add 1/4 from both sides of equation, and it gave us, . And it gave us the answer is<u><em> </em></u><u><em>x=5/8 is the final answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
Step-by-step explanation:
<h2>1).</h2>
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180°</h3>
where
n is the number of sides
From the question, the number of sides is 50 that's n = 50 .
Substitute the value into the above formula and solve.
We have
(50 - 2 ) × 180 = 48 × 180
<h3>The answer is 8640°</h3>
<h2>2).</h2>
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180°</h3>
where
n is the number of sides
From the question the sum of the angles is 2160°
Substitute the values into the above formula and solve for the number of sides.
That's
2160 = (n - 2) × 180
2160 = 180n - 360
180n = 2160 + 360
180n = 2520
Divide both sides by 180
n = 14
<h3>Therefore the number of sides is 14</h3>
<h2>3).</h2>
The exterior angle of a polygon can be found by using the formula
<h3>
</h3>
where
n is the number of sides
From the question the number of sides is 6 that's n = 6.
Substitute the value into the above formula and solve.
We have
<h3>
</h3>
We have the final answer as
<h2>60°</h2>
Hope this helps you.
