Please do questions 31-34 I need them ASAP in 2h

Step-by-step explanation:

31) 1  1/4 × 8/9

multiply the denominator(4) with 1 which is 4 itself, then add 4 with the numerator(1) which is 5. therefore you will get,

⇒5/4 × 8/9

⇒ 5×8/4×9

⇒40/36

⇒10/9

32) 2/3 × 2  1/4

multiply the denominator(4) with 2 which is 8, then add 8 with the numerator(1) which is 9. therefore you will get,

⇒2/3 × 9/4

⇒2×9/3×4

⇒18/12

⇒3/2

33) 2  2/9 × 3/4

multiply the denominator(9) with 2 which is 18, then add 18 with the numerator(2) which is 20. therefore you will get,

⇒20/9 × 3/4

⇒20×3/9×4

⇒60/36

⇒5/3

34) 4/5 × 2  11/12

⇒4/5 × 35/12

⇒4×35/5×12

⇒140/60

⇒7/3

35) 3  1/21 × 3/8

⇒64/21 × 3/8

⇒64×3/21×8

⇒192/168

⇒8/7

36) 1  1/5 × 3  1/4

⇒6/5 × 13/4

⇒6×13/5×4

⇒78/20

⇒39/10

37) 1  1/4 × 2  2/3

⇒5/4 × 8/3

⇒5×8/4×3

⇒40/12

⇒10/3

38) 1  1/5 × 3  3/4

⇒6/5 × 15/4

⇒6×15/5×4

⇒90/20

⇒9/2

39) 3  2/7 × 2  5/8

⇒23/7 × 21/8

⇒23×21/7×8

⇒483/56

⇒69/8

40) 3  1/9 × 2  1/7

⇒28/9 × 15/7

⇒28×15/9×7

⇒420/63

⇒20/3

hope it helps you!!

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
