50% off means half price, so half of 49.98 is 24.99
the necklace now costs 24.99 dollars
Total distance covered = 5 x 30 = 150 miles
Angle of travel with respect to south pole = 180 - 164°56' = 15°4'
Let the distance southwards covered be x, then
cos 15°4' = x/150
Thus, x = 150 cos 15°4' = 144.84
Therefore, the distance covered southwards = 145 miles to the nearest mile.
Multiplication property of equality
Step-by-step explanation:
We are given that the equation

We have to find the property which was applied to solve the equation.

Reason: Given
Multiply by -8/3 on both sides

By using multiplication property of equality.

After simplification

Answer:
5545
Step-by-step explanation:
Answer:
The 1/4th power means the 4th root of a number.
Therefore for the first question, the answer should be 4th root of 1296 -4th root of 625. or \sqrt[4]{1296}
4
1296
-\sqrt[4]{625}
4
625
:D
For the second question just calculate? what to the 4th power is 1296 and what to the 4th power is 625?
They should respectively be 6 and 5. So the final answers we get is 6-5=1
