How many meters are there in 21 feet? - CORRECT ANSWER 3.25 feet = 1 meter 1 foot = 1÷3.25 meters 21 feet = 21×1÷3.25 = 6.4615 meters What is the x value such that y =15 - 3x and y = 0? - CORRECT ANSWER y =15 - 3x and y = 0 Hence 15 - 3x = 0 Hence 3x = 15 x = 5 Put these four fractions in order from smallest to largest: 1/4, 2/3, 4/7, 1/2 - CORRECT ANSWER If 1/4, 2/3, 4/7, 1/2 are converted to decimals we get 0.25, 0.6666...., 0.571....., 0.5 then the correct order is obvious or If 1/4, 2/3, 4/7, 1/2 are converted to fractions with a common denominator 21/84, 56/84, 48/84, 42/84 then the correct order is obvious. On a number line what is the distance between -3/7 and -2/3 ? - CORRECT ANSWER The distance between numbers can be found by using absolute values (|a| or abs(a)). The distance between these numbers is abs(-3/7 − -2/3 ) = abs(-(3/7 -2/3)) = abs(3/7 -2/3) = abs(9/21 - 14/21) = abs(-5/21 ) =5/21 An isosceles triangle has two equal sides. If two of the sides are 5 inches and 2 inches how long is the perimeter? - CORRECT ANSWER The other side must be 5 inches otherwise the two shorter sides could not meet. The perimeter is the distance around the outside of the triangle and is 5 + 5 + 2 = 12. The cylinder below has r = 10 inches and a volume of 6283 cubic inches to the nearest cubic inch. Find the height of the cylinder to the nearest inch. - CORRECT ANSWER The volume of this cylinder is 6283. (pi)r2h = 6283. h is the height. (pi) is 3.14... h = 6283÷(pi)÷100 = 19.999.... h = 20 The height of the cylinder is 20 inches. -5 + 4 - CORRECT ANSWER -1 16 x 8 - CORRECT ANSWER 128 25 % of 160 - CORRECT ANSWER 40 -10 x -5 - CORRECT ANSWER 50 1/15 ÷ 3/5 - CORRECT ANSWER 1/9 2.4 x 3 - CORRECT ANSWER 7.2 -50 ÷ -50 - CORRECT ANSWER 1 9 - (-13) - CORRECT ANSWER 22 5/6 + 7/12 - CORRECT ANSWER 1 ₅/₁₂ 56 ÷ 3 - CORRECT ANSWER 18 R 2 $2.45 - $1.96 - CORRECT ANSWER $0.49 3/8 x 4/9 - CORRECT ANSWER 1/6 100% of 36 - CORRECT ANSWER 36 7/10 - 2/5 - CORRECT ANSWER 3/10 20 is what % of 40 - CORRECT ANSWER 50% 54 + 23 - CORRECT ANSWER 77 545-89 - CORRECT ANSWER 456 211 x 16 - CORRECT ANSWER 3376 8.5 - 1.074 - CORRECT ANSWER 7.426 14.64 - 10.8 - CORRECT ANSWER 3.84 6.25 x 1.4 - CORRECT ANSWER 8.75 20.45 ÷ 5 - CORRECT ANSWER 4.09 ¾ = /16 - CORRECT ANSWER 12 3 ₇/₈ ÷ 5 ₁/₆ - CORRECT ANSWER ¾ 9 ÷ ¹/³ - CORRECT ANSWER 27 [Show More]
