If you post just 5 of these questions, I'll try to help you. Twenty questions is simply too many at once!
then just do what she says / : /
To answer each question:
Question 1: To describe a fraction as a decimal, divide the numerator (137) by the denominator (6). The correct answer is a repeating decimal 22.83 with a bar over 3.
Question 2: To find the total household waste generated, add the amounts of waste generated in each year. The correct answer is 7.15 * 10^7 tons.
Question 3: To simplify the expression, multiply 54 by 5^-6. The correct answer is the fraction 1 over 5 to the power 2.
Question 4: A rational number is a number that can be expressed as a fraction, where both the numerator and denominator are integers. The square root of 79 is not a rational number.
Question 5: To find the total number of cherries, multiply (37)^2 by 30. The correct answer is 314 cherries.
Question 6: To find the difference between the distances of Jupiter and Mercury from the Sun, subtract the distance of Mercury from the distance of Jupiter. The correct answer is 7.2 * 10^7 kilometers.
Question 7: To simplify the expression p-m ÷ p-n, subtract the exponents of p and divide by the difference in exponents of m and n. The correct answer is p-m - n.
Question 8: To find the value of p in the equation (62)^p = 610, solve for p by taking the logarithm of both sides. The correct answer is 4.
Question 9: Scientific notation represents numbers using powers of 10. All of the given numbers are in scientific notation.
Question 10: To arrange the expressions from least to greatest on a number line, compare the values of each expression. The correct answer is 11 over 9, square root of 5, square root of 11, square root of 20.
Question 11: To find the total number of pigs, multiply (64)^2 by 60. The correct answer is 648 pigs.
Question 12: To find the value of the expression, divide the numerator by the denominator. The correct answer is 3.0 * 10^7.
Question 13: To express a repeating decimal as a fraction, set up an equation where x is equal to the repeating decimal and solve for x. The correct answer is 2 over 9.
Question 14: To simplify the expression, multiply the bases and subtract the exponents. The correct answer is 6^7.
Question 15: To find the total mass of the gas in the container, multiply the number of atoms by the weight of each atom. The correct answer is 8.42 grams.
Question 16: To simplify the expression, raise 95 to the seventh power. The correct answer is 93.
Question 17: To find the value of x, take the square root of 50. The correct answer is plus or minus square root 50.
Question 18: To find the product of two numbers in scientific notation, multiply the coefficients and add the exponents. The correct answer is 8.4 * 10^6.
Question 19: To divide powers with the same base, subtract the exponents. The correct answer is 10^11.
Question 20: To represent the values of x for the equation x^2 = 100 on a number line, consider both the positive and negative square roots of 100. The correct answer is a number line from negative 60 to 0 to positive 60, with dots on positive 10 and negative 10.
