Hey<br> pls solve this question <br><br>​
Sholpan [36]

Answer:

(13/2)^27

Step-by-step explanation:

First note that ( )^0 = 1, so we need not bother with the last term.

Next, note that

 (2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).

Finally, we must cube this last result.  We get:  (2/13)^(-9*3) = (2/13^(-27)

or

(13/2)^27

Note:  we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.

miss Holman gave a 90 cent tip to a waitress for serving a meal costing $6.00. What percent of the bill was her tip. Please show
lara [203]

Answer:

Percent of bill that was tip = 15%

Step-by-step explanation:

Tip = 90 cent

Price of meal = $6.00

Converting dollar to cent

1 cent = 1/100 dollar

90 cent = 90/100 dollar = 0.9 dollar

Percent of bill that was tip = Tip/Price of meal * 100

Percent of bill that was tip= 0.9/6 * 100%

Percent of bill that was tip = 15%

Solve 3.8 = p/3 - 7.2. Solve for p.
Murljashka [212]

Answer:

I believe the answer to your question is p = 33

Step-by-step explanation:

Question: p÷3 - 7.2 = 3.8

Step 1: Add 7.2 to both sides of the equation

p÷3 - 7.2 = 3.8

+7.2           +7.2

p÷3 = 11

Adding 7.2 to both sides cancels out 7.2 on the left and whatever you do unto one side of an equation, you must do to the other (it's just a rule in math)

Step 2: Multiply by 3 on both sides

p÷3 = 11

x 3     x 3

p = 33

Same as last time; multiplying by 3 cancels out 3 on the left and whatever you do unto one side, you must do to the other

Which rectangles have the same areas but greater perimeters than the one shown below? Choose all that apply.
Firlakuza [10]

The  rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.

<h3>What is area?</h3>

Area is the amount of space occupied by a two dimensional shape or object.

A rectangle is shown with a length and height of 6 ft. Hence:

Area = (6 * 6) = 36 ft²

Perimeter = 2(6 + 6) = 24 ft

For 12 ft by 3 ft:

Area = (12 * 3) = 36 ft²

Perimeter = 2(12 + 3) = 30 ft

For 9 ft by 4 ft:

Area = (9 * 4) = 36 ft²

Perimeter = 2(9 + 4) = 26 ft

For 8 ft by 3 ft:

Area = (8 * 3) = 24 ft²

Perimeter = 2(8 + 3) = 24 ft

For 7 ft by 4 ft:

Area = (7 * 4) = 28 ft²

Perimeter = 2(7 + 4) = 26 ft

For 18 ft by 2 ft:

Area = (18 * 2) = 36 ft²

Perimeter = 2(18 + 2) = 40 ft

The  rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.
