For each handmade greeting card jacqui sells she makes a profit of $0.35. in one week, she profit of $42. she sells the cards for $0.75 each. a. about how many greeting cards did jacqui sell that week? b. about how much did she earn before paying expenses?

The equation we can generate from this is:

P = 0.35 x

where P is profit, and x is the number of cards made

 

A. when P = 42

42 = 0.35 x

x = 42 / 0.35

x = 120 cards

Therefore Jacqui sold 120 cards that week

 

B. To find for the total earning before expenses:

total earning = $42 + $0.75 * 120

total earning = $132

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 )
