Can someone help me with these problems? The majority of them I have answers but I don't understand them. Thanks!What is the area of the triangle with a base of 5 1/2 cm and a height of 3 1/2 cm?My answer - 11 1/2919÷ 2Round to the nearest wholeMy answer-?What is the area of a parallelogram with a base of 14.5 m and a height of 21 m?The cafeteria sold 200 grilled cheese sandwiches, 100 tacos, and 150 grilled chicken salads. What is the ratio in simplest terms of grilled chicken salads sold to the total number of lunches sold?My Answer- 1:3What is the ratio of odd to even digits in the following number:7,208,631My Answer- 3:4Given that one ton is equal to 2000 pounds, what is 5 tons?My Answer- 400 or 1000A table measures 3 feet across. How many inches is this?My Answer-36

Answer:The corresponding answers to the questions are  9.625 cm² , 459, 304.5m², 1 : 3 , 3:4 , 10,000 pounds , 36 inches.Step-by-step explanation:1. Area of triangle = 0.5 x base length x heightHere base length = 5.5cm and height = 3.5cmSo area will be 0.5 x 5.5 x 3.5 cm² = 9.625 cm²2.919/2 rounding off to nearest wholeWe know that the value of 919/2 = 459.5 .So the nearest whole number value to which it can be rounded off is 459.3.We know that area of parallelogram is base length x heightHere, base length =14.5m and height = 21mSo area = 14.5 x 21 m² = 304.5m²4.No. of grilled cheese sandwiches sold = 200No. of tacos sold                                     = 100No. of grilled chicken salads sold          = 150Total lunches sold                                   = 200 + 100 + 150 = 450So, ratio of chicken salads to lunches sold is 150 : 450 = 1 : 35.Given number : 7,208,631Odd digits here - 7,3,1 - 3 digitsEven digits here - 2,0,8,6 - 4 digitsSo, ratio of odd digits to even digits is 3:46.One ton = 2000 poundsSo 5 tons = 5 x ( 1 ton) = 5 x 2000 pounds = 10,000 pounds7.Table length = 3 feetWe know that 1 foot = 12 inchesSo table length = 3 foot = 3 X 12 inches = 36 inches
