Need answered ASAP!!!!!Which expression will produce a positive product?

(–12)(12)(–6.3)(–0.2)(–15.9)

(12)(12)(6.3)(0.2)(–15.9)

(12)(–6.3)(–0.2)(–15.9)

(–12)(12)(–6.3)(–0.2)(–15.9)(0)

Answers

Obviously, we need to solve each of the expression on a piece of paper to figure it out. I checked it out and this is what I got....

((((−12)(12))(−6.3))(−0.2))(−15.9)
=(((−144)(−6.3))(−0.2))(−15.9)
=(907.2)(−0.2)(−15.9)
=(−181.44)(−15.9)
=2884.896

Thats the first option. It came out Positive! :)

(12)(12)(6.3)(0.2)(−15.9)
=(144)(6.3)(0.2)(−15.9)
=(907.2)(0.2)(−15.9)
=(181.44)(−15.9)
=−2884.896

Thats the second option, it came out negative.

(12)(−6.3)(−0.2)(−15.9)
=((−75.6)(−0.2))(−15.9)
=(15.12)(−15.9)
=−240.408

Thats the third option, it came out negative

(((((−12)(12))(−6.3))(−0.2))(−15.9))(0)
=((((−144)(−6.3))(−0.2))(−15.9))(0)
=(907.2)(−0.2)(−15.9)(0)
=((−181.44)(−15.9))(0)
=(2884.896)(0)
=0

Thats the fouth option, it came out as Positive zero.

You mix 2/5 cup of red paint for every 1/4 cup of blue paint to make 1 5/8 gallons of purple paint. How much red paint and blue paint do you use

Answers

Answer=16 cups of red and 10 cups of blue

2/5=8/20=32/80
1/4=5/20=20/80
1 5/8gallons=26cups

32/80+20/80=52/80

26=x(52/80)
divide both sides by (52/80)
40=x
In short, you multiply the mixture by 40 , so...

40*2/5=16cups of red
40*1/4=10cups of blue

Simon bought 2 pounds of cucumbers, 8 ounces of alfalfa sprouts, 3 pounds of lettuce, and 15 ounces of tomatoes. How many ounces of vegetables did he buy in total?

Answers

Answer=103 ounces

First we need a conversion equations to get from pounds to ounces

1pound=16ounce

2pounds=2*16=32 ounces of cucumber

3pounds=3*16=48 ounces of lettuce

Now that all of the vegetables are in ounces, we can solve for their total weight.

x=32+8+48+15=103 ounces

He bought 103 ounces of vegetables in total.

If you would like to know how many ounces of vegetables did Simon buy in total, you can calculate this using the following steps:

1 pound equals to 16 ounces.
2 pounds + 8 ounces + 3 pounds + 15 ounces = 2 * 16 + 8 + 3 * 16 + 15 = 32 + 8 + 48 + 15 = 103 ounces

Result: Simon bought 103 ounces in total.
