Melissa and Joey enjoyed dinner at a restaurant. They paid the waiter $100.50 plus a 20% tip. How much did each person pay if they split the total bill in half?

Answer:

B:Both powers should be in the denominator with positive exponents.

Step-by-step explanation:

We are given that Tyler simplified an expression

We have to find an error which Tyler makes in her simplification

Step 1:

Step 2:

Step 3:

Hence, Tyler's error is both exponents should be denominator with positive exponents.

Answer:B:Both powers should be in the denominator with positive exponents.

Answer:

Step-by-step explanation:

                                                        1

Tyler correctly rewrote x^(-3) as ------- , but

                                                       x³

                                                       1

he incorrectly wrote y^(-9) as   ---------

                                                    y^(-9)

Both x^9 and y^9 should be in the denominator.  This corresponds to the 2nd given possible answer.

Answer:

True

Step-by-step explanation:

 Given: Statement :"The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units"    

We have to choose whether the given  statement s true or false.

Consider the given statement.

The area of a circle of radius 14 units is equal to the surface area of a sphere radius 7 units  

We first find the area of circle with 14 units radius and area of a sphere with 7 units radius and compare the two values.

We know,

Area of circle =

given : r = 14 units

So, Area of circle =  

Simplify, we have,

Area of circle = units²

Now,  

Area of sphere =

given : r = 7 units

So, Area of sphere  =  

Simplify, we have,

Area of sphere = units²

Since, Area of circle with radius 14 units is equal to the area of sphere with radius 7 units.

Thus, The given statement is true.
