Answer:
65038.55
Step-by-step explanation:
First, Let's turn 12.3% into a decimal which is 0.123
Then Multiply 57,915 by 0.123
57,915 × 0.123= 7123.545 Round; 7,123.55
Then Add [Mark up = Add] 57,915 with 7,123.55
57,915 + 7,123.55= 65038.55
Hence, the Answer is 65038.55
Answer:
see explanation
Step-by-step explanation:
Using Pythagoras' theorem, that is
The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.
Using x instead of ?
(a)
The hypotenuse is the side opposite the right angle, that is 74, thus
24² + x² = 74²
576 + x² = 5476 ( subtract 576 from both sides )
x² = 4900 ( take the square root of both sides )
=
x = 70
----------------------------------------------------------------------
(b)
The hypotenuse x is the unknown side here
x² = 40² + 40² = 1600 + 1600 = 3200
Take the square root of both sides
=
≈ 56.6 ( nearest tenth )
