What is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)?

Answers

Answer: 6,8 and 10

Step-by-step explanation:

To find the length , all we need to find is the distance between each point ,

the formula for calculating distance between two points is given by :

D = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

Let the points be :

A ( -5,-1)

B(-5,5)

C(3,-1)

Calculating the length AB , we have

D1 = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

D1 = $\sqrt{(-5+5)^(2)+(5+1)^(2)}$

D1 = $√(36)$

D1= 6

Calculating the length AC , we have

D2 = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

D2 = $\sqrt{(3+5)^(2)+(-1+1)^(2)}$

D2 = $√(64)$

D2 = 8

Calculating the length BC , we have

D3 = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

D3 = $\sqrt{(3+5)^(2)+(-1-5)^(2)}$

D3 = $√(100)$

D3 = 10

Therefore ,the length of the sides of the triangle are 6,8 and 10

Answers

12) 8 liters in total. each glass holds 1/5 of a liter. 8 x 5 = 40 glasses.

13) 3bars/4people = 3/4 of a bar.

14) same concept as 13. .5quart/3people = (1/6) of a quart of milk.

15) 3 yards in total. divides it into pieces that are 1/4 yard long. so each 1 yard makes 4 pieces. that means 3 yards makes 12 pieces in total.

12) 5 glasses per liter. 5 * 8= 40 glasses

Total is 3 bars
14) 1 quart equals 4 cups
Caleb- 1 1/3 cup
Friend 1- 1 1/3 cup
Friend 2- 1 1/3 cup
15) 3/ 1-4 = 12 pieces

Use 3.14 for pie
A.248.5 yard
B.490.5 yard
C.725.5 yard
D.745.5 yard

Answers

Answer:

Step-by-step explanation:

d= 25 yards ; r = 25/2 = 12.5 yards

circumference of two semicircle = circumference of circle

= 2πr = 2*3.14*12.5 = 78.5 yards

Perimeter of school truck = 78.5 + 85 + 85 = 248.5 yards

Distance traveled by Jasmine = 3* 248.5 = 745.5 yards
