Is 8yd greater or less than 288in

Answers

12 inches make 1 foot

3 feet make 1 yard.

1 yard = 3 feet = 3*12 = 36 inches.

1 yard = 36 inches.

8 yards = 8*36 = 288 inches.

8 yards is not greater or not less than 288 inches.

8 yards is equal to 288 inches.

What is the complement of 86.4 degrees ?

Answers

Complement for angles means that the total degrees adds up to 90. (these are called complementary angles, supplementary angles add up to 180 degrees!)

Since you already have 86.4, you simple subtract.

90-86.4=3.6

your final answer is 3.6 degrees.

Answers

Jacks!!!!!!!! Would be correct!!!!

Final answer:

The spiciness of chili is determined by comparing the proportion of chili powder to tomato sauce. Jack consistently uses 222 teaspoons of chili powder per cup of sauce, whereas Marsha's ratio varies, but never exceeds 126.86 teaspoons per cup. Therefore, Jack's chili is spicier.

Explanation:

To determine whose chili is spicier, we must compare the ratio of chili powder to tomato sauce used by Jack and Marsha. Jack uses 222 teaspoons of chili powder for every 1 cup of tomato sauce. For Marsha, we'll have to establish the ratios based on her table.

When Marsha uses 444 teaspoons of chili powder, she uses 3.5 cups of tomato sauce. So, her ratio for this batch is 444/3.5 = 126.86 teaspoons of chili powder per cup of sauce.
When Marsha uses 888 teaspoons her ratio is 888/7 = 126.86 teaspoons per cup.
When she uses 1212 teaspoons, her ratio is 1212/10.5 = 115.43 teaspoons per cup.

Regardless of the quantity she makes, Marsha's ratio never goes below 115.43, which is less than Jack's ratio of 222. So, Jack's chili is spicier than Marsha's.
