Roland purchased a new pair of shoes online that normally sell for $125.00 but were marked down to $93.75. What is the discount

Ad libitum [116K]

Answer:

25%

Step-by-step explanation:

125.00x = 93.75

x = 93.75 / 125 = 0.75

meaning that 93.75 is 75% of 125

and, therefore, the item was discounted 100 - 75 % = 25%

How many yards will Ms. Angela need if she wants to make 10 of each type of mask if adding she has 2 1/2

Helga [31]

Answer:

$Total = 25\ yd$

Step-by-step explanation:

The given parameters can be represented as:

$Length = 2\frac{1}{2}$

$Number=10$

Required

The total yards

This is calculated as:

$Total = Number * Length$

$Total = 10 * 2\frac{1}{2}\ yd$

Convert fraction to decimal

$Total = 10 * 2.5\ yd$

$Total = 25\ yd$

Jorge randomly selects a digit from 0 to 9. What is the probability that the digit he selects is a prime number?

zloy xaker [14]

Step-by-step explanation:

{0,1,2,3,4,5,6,7,8,9}--set of numbers from 0 to 9

{2,3,5,7}---set of prime numbers from 0 tp 9

there are 10 numbers in the first set and 4 numbers in the second set.

4/9 is the probability that the digit he selects is a prime number

Hope that helps :)

A triangle has vertices at (-1,5), (4,2), and (0,0). What is the perimeter of the triangle

yan [13]

The perimeter of the triangle is 15.4 units.

Step-by-step explanation:

The triangle has vertices at (-1,5), (4,2), and (0,0).

To find the perimeter of the triangle, you need to find the distance of the three points which is the length of the three sides of the triangle.

Let us consider the points as A (-1,5) and B (4,2) and C (0,0).

The distance formula is given by :

⇒ $\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }$

Distance of AB :

A (-1,5) ⇒ (x1,y1)

B (4,2) ⇒ (x2,y2)

⇒ $\sqrt{(4+1)^{2}+(2-5)^{2} }$

⇒ $\sqrt{5^{2}+-3^{2} }$

⇒ $\sqrt{25+9}$

⇒ $\sqrt{34}$

⇒ 5.8

∴ The length of the side AB of the triangle is 5.8 units.

Distance of BC :

B (4,2) ⇒ (x1,y1)

C (0,0) ⇒ (x2,y2)

⇒ $\sqrt{(0-4)^{2}+(0-2)^{2} }$

⇒ $\sqrt{16+4 }$

⇒ $\sqrt{20}$

⇒ 4.5

∴ The length of the side BC of the triangle is 4.5 units.

Distance of CA :

C (0,0) ⇒ (x1,y1)

A (-1,5) ⇒ (x2,y2)

⇒ $\sqrt{(-1-0)^{2}+(5-0)^{2} }$

⇒ $\sqrt{1+25}$

⇒ $\sqrt{26}$

⇒ 5.1

∴ The length of the side CA of the triangle is 5.1 units.

Now, the perimeter of the triangle is given by :

Perimeter = Sum of the lengths of all three sides of the triangle.

⇒ 5.8 + 4.5 + 5.1

⇒ 15.4 units.

∴ The perimeter of the triangle is 15.4 units.
