OR 3.25x = y (y being 3-9)
Answer:
161.5 in.^2
Step-by-step explanation:
Since you don't have a figure, from your description, I understand that the base of each small upper triangle is 8.5 inches. That means that each small triangle on top has a base of 8.5 inches and a height of 5 inches, and each small triangle below has a base of 8.5 inches and a height of 13 inches. My calculations below are base don this understanding.
The area of a kite is
A = (Bb)/2
where B and b are the lengths of the diagonals.
The diagonals have lengths:
B = 13 in. + 6 in. = 19 in.
b = 8.5 in. + 8.5 in. = 17 in.
A = (Bb)/2
A = (19 in. * 17 in.)/2
A = (323 in.^2)/2
A = 161.5 in.^2
Answer:
x=-12.5
Step-by-step explanation:
divide both sides
-0.2/(-0.20)=2.5/(-0.2)
x=2.5/(-0.2)
x+-12.5
Answer:
(3a-1)(3a+1)
Step-by-step explanation:
This is the difference of two squares so we can factorise using the rules
x^2-y^2 = (x-y)(x+y)
In this case x = 3a and y = 1 since (3a)^2 = 9a^2 and 1^2 = 1
B) 57%
Add up Garys hours spent on internet and games to get total time
12+8=20
To get the percent of time used on internet and games, divide by total time
20/35 = 0.57
