What symbol do you use for square root on pc?

Answers

For this case we must find the values of "a" and "b" that make the expressions equivalent:

We have:

$\sqrt {\frac {126xy ^ 5} {32x ^ 3}} =$

We take common factor "2" from the numerator and denominator:

$\sqrt {\frac {2 * (63xy ^ 5)} {2 * (16x ^ 3)}} =$

Eliminating common factors of numerator and denominator:

$\sqrt {\frac {63y ^ 5} {16x ^ 2}} =$

So, we have that the values of a and b are:

$a = 16\nb = 2$

Answer:

$a = 16\nb = 2$

A circular ink spot has the circumference of 25.12 millimeters. A minute later, it has the circumference of 75.63 millimetersA. Estimate the diameter of the ink spot each minute

B. How many times greater is the diameter of the ink spot compared to the previous minute?

Answers

A) minute 1) diameter = 7.995946004446154 mm
minute 2) diameter = 24.07378170048816 mm

(I'll assume that you can round if necessary)

B) The diameter of the new ink spot is roughly 3X larger
(technically 3.01074841 X larger)

tiffany plans to use $275 she earned from a summer job to buy some new clothes for school. she found several items she likes but is trying to decide if she has enough money to buy all of them . she wants to buy three pairs of jeans for $42 each and five shirts with an average cost of $27 per shirt. she will have to pay 6% sales tax

Answers

Answer:

Total amount Tiffany has to pay = $276.66

Step-by-step explanation:

Cost of one pair of jeans = $42

Cost of three pairs = 3(42) = 126

Cost of one shirt = 27

Cost of five shirts = 5(27) = 135

Total amount Tiffany has to pay = 126 + 135 = 261.

Sales tax = 6%

6% of 261 = 0.06(261) = 15.66

So, total amount including sales tax Tiffany has to pay = 261 + 15.66 = 276.66.

The total cost without tax would be $261, sales tax would be $15.66, if we add them add the answer would be $276.66.

Amy is putting a new floor in her bathroom. She created a scale drawing of her bathroom floor using a scale of 1/2 inch = 1 foot. In the drawing, the bathroom measures 3 inches by 3 1/2 inches. Amy is purchasing square tiles that measure 1/2 foot on each side. The cost of each tile is $3.00. How much will Amy pay for the tiles for her bathroom floor?

Answers

Amy will pay $3.00 for the tiles for her bathroom floor.

What is Fraction?

A fraction represents a part of a whole.

The scale is 1/2 inch = 1 foot.

Length of bathroom = 3 inches × (1 foot / 24 inches)

= 1/8 feet

Width of bathroom = $3(1)/(2)$ inches(1 foot / 24 inches)

= 7/24 feet

We need to calculate the total area of the bathroom floor in square feet:

Area of bathroom floor = (length) x (width)

= (1/8 feet) x (7/24 feet)

= 7/192 square feet

Since each tile measures 1/2 foot on each side, the area of each tile is:

Area of one tile = (1/2 feet) x (1/2 feet) = 1/4 square feet

Total area of tiles needed = (area of bathroom floor) / (area of one tile)

= (7/192 square feet) / (1/4 square feet)

= 7/48 tiles

Amy will need to purchase 1 tile at a cost of $3.00 per tile, so the total cost of the tiles for her bathroom floor will be:

Total cost = (number of tiles) x (cost per tile)

= 1 tile x $3.00/tile = $3.00

Hence, Amy will pay $3.00 for the tiles for her bathroom floor.

Answer:

$78.00

Step-by-step explanation:

First, you would have to figure out how many tiles she would need. 3 inches is equal to 6 feet according to the scale part, and then it would be 12 tiles because it is half a foot for the tiles. Then 3 1/2 would be 7 feet, and then 14 tiles. 12 plus 14 equals 26, and 26 times $3.00 is $78.00

Please simplify 8/243.
