Teresa has scored 77, 80, 63, 61 and 92 on previous test what score does she need on her next test on her average will be 77

Average = 77=(77+80+63+61+92+Next test)/6

Therefore, 77*6=77+80+63+61+92+Next test

Next test score = (77*6)- (77+80+63+61+92)= 89

89,because if you try dividing 373 by 5 it’s 74, so first try adding 77 to 373 which is 450 and divide that by 6 which is 75. Now what you have to do is to add numbers to 373 and divide it by 6 until you get an average of 77. Ex: 373+78=451 451 divided by 6 is 75.16 which isn’t right so you just keep trying different numbers

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
