Answer:
Step-by-step explanation:
In each case, square the coordinates of the point and determine whether or not the sum of these squares is 1:
A) 4/9 + 5/9 = 9/9 YES
B) 1 + 1 = 2 NO
C) 3/4 + 1/9 Not equal to 1. NO
D) 0.64 + 0.36 = 1.00 YES
Step-by-step explanation:
a) Using the distance formula,

b) Using the slope formula,

c) The triangle is <em>scalene</em> because each of the sides is of a different length.
Answer:
X=63 y=27
Step-by-step explanation:
X and 117 are on a straight line. All straight lines = 180 degrees.
180 - 117 = 63
90 - 63 = 27
Answer:
D. 3200 square feet
Step-by-step explanation:
(2)(20)*(2)(40)=3200
Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.
Your equation should look like:
5h + 20 = 90
Subtract 20 from both sides.
5h = 70
Divide both sides by 5.
h = 14
Gina can rent a surfboard for 14 hours if she has $90.
