Answer:1/4
Step-by-step explanation:
Each term is multiplied by 1/4 to get to the next
Therefore 1/4 is the common ratio
We use the equation 2x+8x=50.
10x=50
x=5
The rectangle will be 20 cm long and 5 cm wide.
Hope this helps!
Hey You!
The GCF of 24 and 60 is 12.
We can divide 24 and 60 by 12, so the simplest form would be: 2/5
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
Answer:
Ray, you need the slope-intercept formula y=mx+b
Step-by-step explanation:
Next you'll need 2 points, any points are fine. Just find two easy ones along the line. I'll just pick Point 1 as P1 = ( 0,4) and point 2 as P2 = (4,0) because they are easy to work with.
next use
point P1 (0,4) in the form (x1,y1)
point P2(4,0) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (0-4) / (4-0)
m = -4 / 4
m = -1
now use the point slope with one of the points, to find the slope-intercept form.
y - y1 = m(x -x1)
y - 4 = -1(x-0)
y -4 = -x
y = -x + 4
note:
y = mx +b
y = (-1)x + b is the form. see?
