The answer is 20%.

Step 1: Subtract the measured distance and the actual distance to calculate the error.
Step 2: Divide the given value by the actual distance and convert it into the percentage.

the actual distance is 612 ft
the measured distance is 735 ft

Step 1: 735 ft - 612 ft = 123 ft
Step 2: 123 ft / 612 ft = 0.20 = 20/100 = 20%

A baker needs 3/5 cup water for every 2/3 cup flour. Using this ratio, how much flour is needed for 1/3 cup water?
Llana [10]
<h3>Answer:  Choice A)  10/27 cup flour</h3>

=======================================================

Work Shown:

3/5 cup water = 2/3 cup flour

15*(3/5) cup water = 15*(2/3) cup flour

9 cups water = 10 cups flour

9/27 cup water = 10/27 cup flour

1/3 cup water = 10/27 cup flour

In the second step I multiplied both sides by 15 to clear out the fractions. In the second to last step, I divided both sides by 27 so that it forms the fraction 9/27 which reduces to 1/3.

(25 points to correct answer)
Kobotan [32]

Answer:

The area of a sector GHJ is 36.3\ cm^{2}

Step-by-step explanation:

step 1

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=8\ cm

substitute

A=\pi (8)^{2}

A=64\pi\ cm^{2}

step 2

Remember that the area of a complete circle subtends a central angle of 360 degrees

so

by proportion find the area of a sector by a central angle of 65 degrees

\frac{64\pi}{360}=\frac{x}{65}\\ \\x=64\pi (65)/360

Use \pi =3.14

x=64(3.14)(65)/360=36.3\ cm^{2}
