Answer:

57/100

Step-by-step explanation:

This is the answer because:

1) Since 0.57 in the hundredths place, the denominator is going to be 100

2) We have 57 of a 100, therefore, 57 is going to be the numerator

3) Now, our fraction is 57/100

4) We cannot simplify this fraction any further because they do not have any common multiples or factors

Hope this helps!

$1 \% = \frac{1}{100}\\ \\90 \% * x =6.4 \\ \\\frac{90}{100}x=6.4 \\ \\\frac{9 }{10 }x=6.4 \ \ *(\frac{10}{9})\\ \\x= 6.4 *\frac{10}{9}\\ \\x=\frac{64}{9}\\ \\x = 7\frac{1}{9}$

A carpenter is making a wooden window frame that has a width of 1 inch. How much wood does the carpenter need to build the frame

romanna [79]

Diagram attached

Answer:

5.5+106 square inches

Step-by-step explanation:

The wooden frame has different shapes- semi circle, rectangles and we would have to calculate area of all the shapes to get the wood required.

To get area of the circle, we use the formula π(R²-r²)/2. Subtract the inner radius from the outer radius =

π(6²-5²)/2= 11π/2

=5.5π square inches

We add area of the semi circle to area of the 3 rectangles from the diagram:

2×1×48×10×1=106 square inches

The rectangle with 10 inches is because we subtracted one inch from both sides of the 12 inches rectangle to avoid repetition and overvaluing the area

Total area =5.5π +106 square inches
