Answer:1695.75
Step-by-step explanation:
We know that there are 7 days in a week. Since 57 people rent skates each day, we know that 57*7=399 skates are rented each week. Since one skate cost 4.25, we know that 399*4.25 is the cost, which is 1695.75. (If you are not allowed to use a calculator, you can do 400*4.25-4.25, to make it easier to compute)
Answer:

Step-by-step explanation:
6/2 = 3
x^6 - x^2 = x^4
3x^4
Answer to problem 5 is A) WU = ZX.
Notice how the angle U is between WU and VU. Similarly, angle X is beween ZX and XY
The order is very important. The angles must be between the two pairs of sides.

Answer to problem 6 is C) 15/17.
Use the pythagorean theorem to find the hypotenuse AC to be 17 units. Then take the ratio of the adjacent and hypotenuse to get the answer.

Answer to problem 7 is choice C
Use the rule cos(90-x) = sin(x) where x = 72-a
Answer:
1
Step-by-step explanation:
By order of operations, we first evaluate the parentheses, which is 2 * 1 = 2. We then evaluate the brackets, which are 3 / 2 = . Finally, * = or 1.
Answer:
The solved expression is and
Therefore
Step-by-step explanation:
Given quadratic equation is
To solve the given equation by using completing the square :
Rewritting the above equation as below :
( it is of the form of heere a=x and b=3 )
Taking square root on both sides we get
Therefore and
