Answer:
48
Step-by-step explanation:
You just have to divide the length of the fabric by the length of the sections
(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
20 over 100 percent is 20%
hope it helps
start with substituting z=e^x
then substitute u = z^(1/6):
that integral has a standard form that can be looked up in integral tables, it has the following solution:
substituting back the the variable z and then x you get the final solution:
Answer:
≈ 4.7 mm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the missing side , then
x² + 5.2² = 7²
x² + 27.04 = 49 ( subtract 27.04 from both sides )
x² = 21.96 ( take square root of both sides )
x = ≈ 4.7 mm ( to the nearest tenth )
