Question

A MACHINE CAN PRODUCE 51 PARTS IN THREE HOURS. HOW MANY PARTS CAN IT PRODUCE IN ONE HOUR?51,68,25,48,17,OR 85? AND:WHICH ANSWER HAS THE LEAST UNIT SIZE?15,QT,5 GAL,OR A AND B ARE EQUAL? LAST:WHAT IS THE SUM OF THE LEAST # OF DEGREES IN AN OBTUSE ANGLE ADDED TO THE GREATEST # OF DEGREES IN AN ACUTE ANGLE?540,180,268,58,OR NONE OF THE ABOVE?

Answer 1

1) 51 parts / 3 hours = 17 parts in one hour
2) I can't read it???
3) An obtuse angle is between 90 and 180 degrees so the least integer number of degrees is 91. An acute angle is between 0 and 90 degrees so the greatest number of integer degrees in an acute angle is 89 degrees. 91 + 89 = 180 degrees.

Answer 2

51 / 3 = 17 parts per hour ( unit rate.) 15 qt is least because 1g=4q and 5g = 20 qt which is greater than 15. Thus, 15 qt is lower (A). obtuse angle - an angle higher than 90 degrees less than 180. So, the least is 91 and acute angle- an angle higher than 1 and less than 90. So, greatest is 89. Therefore, 91+89 = 180 and that's the answer.

Answer 3

1. 51/3=x/1
3x=51
3x/3=51/3
x=17 parts
2. A gal = 4x5=20 quarts, so the correct answer is15 quarts.
3. 91+89=180 degrees.

Answer 4

3 an obtuse angle is greater than 90, and acute angle is less than 90 so answer 3 is 180

Answer 5

first one is 17, 15 QT is less, 180 and 540 are neither acute nor obtuse so its gotta be 268 and 58

Answer 6

1) 51/3= 17
2) 15
3) hmm?

Answer 7

51/3=17 every hour.

Answer 8

17
15 qt
180

Answer 9

17
15qt
180
