The Pythagorean theorem applies to the sides of this right triangle.
... x² + (4/7)² = (5/7)²
... x² = 25/49 -16/49
... x = √(9/49)
... x = 3/7
The unknown side has length 3/7.
_____

Have a nice day!
Answer:
y=5
Step-by-step explanation:
3(3y-4)=33
9y-12=33
9y=45
y=5
On the cube, it measures in numerical order 1 to 6, so:
1,2,3,4,5,6.
We are finding how much red fabric was used for even numbered sides.
So we are looking for sides 2,4,6
Since 20 in. is measured on a side, we can determine the area: 20*2= 40 in.^2 (all sides are same and length*width)
Now we have how much fabric is used on each side, so apply the area to all the even numbers (2,4,6)
40*3= 120 inches
Answer:
The equation of the line is y = 3/4x - 1/4
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 1/2)/(3 - 1)
m = (3/2)/2
m = 3/4
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = 3/4(x - 3)
y - 2 = 3/4x - 9/4
y = 3/4x - 1/4
