All are right.
1. To subtract 0.36 from 6, you can simply subtract 0.36 from 6. The answer is 5.64.
2. To write 6.38 as a common fraction or mixed number in lowest terms, you can start by noting that the whole number part is 6. The decimal part, 0.38, can be expressed as a fraction by placing it over 100 (since it is in the hundredths place). This gives us 38/100. To simplify this fraction, we can divide both the numerator and the denominator by their greatest common factor, which is 2 in this case. Simplifying 38/100 gives us 19/50. Therefore, 6.38 can be written as the mixed number 6 19/50.
3. To find the area of the shaded part in the figure, we need to subtract the area of the circle from the area of the square.
The area of a square is calculated by multiplying the length of one side by itself. In this case, the length of one side of the square is 15 ft, so the area of the square is 15 * 15 = 225 ft^2.
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the radius is half the length of the side of the square, so it is 15/2 ft. Plugging this into the formula, we get A = 3.14 * (15/2)^2 = 3.14 * 225/4 = 706.5/4 = 176.625 ft^2.
To find the area of the shaded part, we subtract the area of the circle from the area of the square: 225 ft^2 - 176.625 ft^2 ≈ 48.375 ft^2. Round this to one decimal place, and the answer is approximately 48.4 ft^2.
4. To find the cost per calculator to the nearest cent, we divide the total cost ($592) by the number of calculators (24). This gives us 592/24. Calculating this division, the answer is approximately $24.67. Therefore, the cost per calculator to the nearest cent is $24.67.
