The stock of Company A gained 5% today to $54.60. What was the opening price of
the stock in the beginning of the day?

Answers

Answer: $51.85

Step-by-step explanation:

To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money for 1%. Then you multiply 5 to figure out 5%. Lastly, you would subtract the answer by $54.60 since your finding out how much it was at the beginning of the day. Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85

$51.85

To find the answer, you would divide $54.60 by 100. You do that to figure out the amount of money of 1%

Then you multiply 5 to figure out 5%. Subtract the answer by $54.60 since your finding out how much it was at the beginning of the day.

Equation: $54.60 ÷100= $.546 x 5= 2.73. 54.60- 2.75 =51.85.

Final result: $51.85

Answer:

True, False, False, False, True, False

Step-by-step explanation:

Coordinates of A, B and C are:

A(-5, -8), B(-8, 1), C(-2, 3)

The distances AB and BC are:

AB = √(-8 + 5)² + (1 + 8)² = √9 + 81 = √90 = 9.48 ≈ 9.5BC = √(-2 + 8)² + (3 - 1)² = √36 + 4 = √40 = 6.32 ≈ 6.3

Perimeter of rectangle:

P = 2(9.5 + 6.3) = 31.6 ≈ 32

Area of rectangle:

A = 9.5*6.3 = 59.85 ≈ 60

Correct choices are: 1 and 5, the rest are incorrect

The radius r of the base of a cone is given by the equation r=(3Vπh)1/2, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for π.

The radius is about
a___inch(es).

Answers

Answer:

1 inch.

STEP BY STEP EXPLANATION:

We are given with the following equation r=(3V/πh)^1/2. By the picture we know that "V' is volume which translated to 5 in this problem, "π" is 3.14 and "h" is out height or 4in (in the picture we get all this values).

Therefore everything that there is left is to substitute and answer.

r = (3[5]/3.14[4])^1/2 - multiply the numbers

r = (15/3.14[4])^1/2 ~ (15/12.56)^1/2 -convert the decimal into a fraction and keep going
