A carpenter who is installing cabinets uses thin pieces of material called shims to fill gaps. The carpenter uses 4 shims to fill a gap that is 1.2 centimeters wide. Three of the shims are 0.75 centimeter, 0.125 centimeter, and 0.09 centimeter wide. What is the width of the fourth shim? Please help answer ASAP thanks
.75 + .125 + .09 = .965
1.2 - .965 = .235
To find the width of the fourth shim, we need to subtract the widths of the three shims that have already been used from the total gap width.
Given:
Gap width: 1.2 centimeters
Width of first shim: 0.75 centimeter
Width of second shim: 0.125 centimeter
Width of third shim: 0.09 centimeter
To find the width of the fourth shim, we need to subtract the sum of the widths of the first three shims from the gap width:
Gap width - (Width of first shim + Width of second shim + Width of third shim) = Width of fourth shim
1.2 cm - (0.75 cm + 0.125 cm + 0.09 cm) = Width of fourth shim
Now, let's calculate the width of the fourth shim:
1.2 cm - (0.965 cm) = Width of fourth shim
0.235 cm = Width of fourth shim
Therefore, the width of the fourth shim is 0.235 centimeters.
