Segments RT and SU are diameters of circle O.What is mSRT?

Pavlova-9 [17]

Angle SRT is undetermined by the question.

A diameter always subtends a right angle (Thales' Theorem, the first in geometry) so we can be assured SRU, STU, RUT and RST are right angles.

A store holiday sale has an item marked down by $10 with an additional discount of 25% off the

ValentinkaMS [17]

Answer:

C : $58.36

Step-by-step explanation:

Given:

A store holiday sale has an item marked down by $10.

Discount on new price = 25%

Final price was $36.27.

Question asked:

what was the original ?

Solution:

Let original price = $x$

New price = $x - 10$

Original price - marked down amount - discount amount = $36.27

$x - 10 -25\% of(x - 10 ) = 36.27\\$

$x - 10 - \frac{25}{100} (x - 10) = 36.27\\x - 10 - 0.25(x - 10) = 36.27\\x - 10 -0.25x +2.5 = 36.27\\0.75x - 7.5 = 36.27\\$

Adding both side by 7.5

$0.75x = 43.77\\$

Dividing both side by 0.75

$x = 58.36$

Therefore, the original price was $58.36
