What is the difference in price per kg between chicken sold at $23.24/kg and turkey sold at $5.17/250 g?
Fed [463]
There are 1000 grams in 1 KILOgram.

therefore in 23.24/kg can be just written using grams as 23.24/1000, since 1kg = 1000 g.

so the price of the chicken per gram is then 23.24/1000 or $0.02324 per gram, roughly 2 and 1/3 pennies per gram.

and the turkey is 5.17/250 in grams already, that gives us $0.02068 per gram, which is roughly 2 pennies.

well, their price difference is 0.02324 - 0.02068, which is 0.00256 per gram  unit.

since we know there are 1000 grams in 1 Kg, how much is that for 1000 grams or a Kg?   0.00256 * 1000 or $2.56.

Jamie kept track of the total hours and minutes she worked this week at the local health food store.
ddd [48]

1 hour = 60 minutes.

Convert the minutes to decimals by diving by 60

30/60 = 0.5

2 hours and 30 minutes = 2.5 hours

45/60 = 0.75

5 hours 45 minutes = 5.75 hours

15/50 = 0.25

3 hours 15 minutes = 3.25 hours

Ow add all the hours:

2.5 + 5 + 5.75 + 3.25 = 16.5 hours

Answer: B. 16.50

Solve by factoring. a^2+2a-35=0
sammy [17]

 

\displaystyle\bf\\a^2+2a-35=0\\\\a^2\underbrace{-5a+5a}+2a-35=0\\\\a^2-5a+7a-35=0\\\\a(a-5)+7(a-5)=0\\\\(a-5)(a+7)=0\\\\\implies~~a-5=0~~or~~a + 7=0\\\\a-5=0~~\implies~~\boxed{\bf a_1=5}\\ \\a+7=0~~\implies~~\boxed{\bf a_2=-7}
