Barry's deck of cards has 40 blue and 70 red. max has 40 blue cards, but the ratio of blue cards to red is 8: 9. how many total cards does max deck have?

The answer is 85 because I foun the unit rate by doing the 40 blue divided by the 8 to find that 5=1 and then multiplied 5 and 9 which equals 45 an added 45 and 40 which is equal to 85 total cards

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 )
