960
Step-by-step explanation:
if each triangle is .25 square centimeters, and you can double them up to make a square that is .5 square cm, you only have to find the area of the grid by doing and then multiply it by four to get 960. it gets multiplied by four because if you double up the trianglse, its multipling the ammount used by two, and then you have each is .5 cm, which you can then make into one whole square cm by doubling up again, or just multiply by four.

<h2>Step-by-step explanation:
The statement
y varies inversely with x is written as
where k is the constant of proportionality
To find k substitute the values of x and y into the equation
From the question
y = 4
x = 6
We have
Cross multiply
k = 4 × 6
k = 24
So the formula for the variation is

Answer:
915 in²
Step-by-step explanation:
The area of the rectangle :
Length = 32 inches
Width = 25 - (10+10) = 25 - 20 = 5 inches
Area of rectangle = Length * width
Area = 32 * 5 = 160 in²
Area of triangle :
Base = 25 inches
Height = (46 - 32) inches = 14 inches
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * 25 * 14 = 175 in²
Total area = (160 + 175)in² = 335 in²
Total area of cardboard :
50 inches * 25 inches = 1250 in²
Amount of cardboard not used :
(1250 - 335) in² = 915 in²
