Answers

Answer:

The numbers in increasing order are:

-1.3, -0.33, 0.4, 0.55

Step-by-step explanation:

We have numbers:

-1.3,0.4,-1/3,5/9

We need to arrange in increasing order.

First convert fractions into decimals.

-1/3 = -0.33

5/9 = 0.55

We have numbers: -1.3, 0.4, -0.33, 0.55

Arranging numbers in increasing order we arrange them form smallest to largest.

The numbers in increasing order are:

-1.3, -0.33, 0.4, 0.55

Final answer:

The numbers -1.3, -1/3, 0.4 and 5/9 in increasing order when placed on a number line are -1.3, -1/3, 0.4, and 5/9. This is calculated by observing that smaller numbers are left on the number line and larger ones are to the right, and by converting fractions to decimals for easier comparison.

Explanation:

In the field of mathematics, a number line is a visual tool used to understand and compare numbers. In a number line, numbers to the left are smaller than those to the right. Comparing your numbers on a number line, you will get them in increasing order as such: -1.3, -1/3, 0.4, and 5/9.

The numbers you presented are in both decimal (-1.3, 0.4) and fraction (-1/3, 5/9) formats. -1.3 is the smallest because it is the furthest to the left on the number line. -1/3 is a negative fraction; its decimal equivalent is around -0.33, which is greater than -1.3. Next, 0.4 is a positive decimal, greater than any negative number. Finally, 5/9 is also positive and its decimal equivalent is approximately 0.56, which is larger than 0.4.

21
27

Answers

Not completely sure on this one, but the answer I would go with is C (21) because if you factor it out it is 3x7. Both of these numbers are prime. The only thing that is confusing me in your question is the 3x3x3. if you are just asking what 3x3x3 is, then it is 9... so A.

Given: x + y = 15.Which of the following are ordered pairs of this equation?

a.{(-3, 14),(0, 15),(3, 16)}
b.{(-3, 16),(0, 15),(3, 14)}
c.{(16, -3),(15, 0),(14, 3)}

Answers

Final answer:

Upon testing all the given sets of ordered pairs, none of the sets satisfy the equation x + y = 15 as when the x and y values are substituted into the equation, they don't sum up to 15.

Explanation:

The task is to determine which of the given sets of ordered pairs satisfies the given equation, x + y = 15. In order to solve this, we can plug in the x and y values from each ordered pair into the equation to see if the equation holds true.

  1. For the set (-3, 14), (0, 15), (3, 16):
    -3 + 14 = 11, which is not equal to 15.
    0 + 15 = 15, which is equal to 15.
    3 + 16 = 19, which is not equal to 15. So this set is incorrect.
  2. For the set (-3, 16), (0, 15), (3, 14):
    -3 + 16 = 13, which is not equal to 15.
    0 + 15 = 15, which is equal to 15.
    3 + 14 = 17, which is not equal to 15. So this set is also incorrect.
  3. For the set (16, -3), (15, 0), (14, 3):
    16 - 3 = 13, which is not equal to 15.
    15 + 0 = 15, which is equal to 15.
    14 + 3 = 17, which is not equal to 15. So this set is also incorrect.

Therefore, none of the options given are ordered pairs of the equation x + y = 15.

Final answer:

The correct set of ordered pairs which satisfy the equation x + y = 15 are {(16, -3),(15, 0),(14, 3)}. The other options contain pairs that do not add up to 15.

Explanation:

The question is about identifying the correct ordered pairs from the given equation x + y = 15. An ordered pair is a pair of elements with a particular order, typically used to describe coordinates on a graph. In this case, we need to find the pairs of numbers that, when added together, equal 15.

Looking at the options:

  • Option a: {(-3, 14),(0, 15),(3, 16)} - These pairs do not add up to 15.
  • Option b: {(-3, 16),(0, 15),(3, 14)} - Only the pairs (0, 15) and (3, 14) add up to 15. The pair (-3, 16) does not.
  • Option c: {(16, -3),(15, 0),(14, 3)} - All these pairs add up to 15.

Hence, the correct option is

C

Elliott's bed is 75 inches long. During his growth spurt, Elliott grew 6 inches. Before his growth spurt, he was 5 feet 11 inches tall. How much shorter is Elliott's bed than Elliott?inches

Answers

Elliott's bed -> 75 in
Elliott before -> 5 ft 11 in = 71 in
Elliott after -> 71 + 6 = 77 in

77 - 75 = 2 in

Elliott's bed is shorter than him by 2 inches.

Each participant in a certain study was assigned a sequence of 3 different letters from the set {a, b, c, d, e, f, g, h}. if no sequence was assigned to more than one participant and if 36 of the possible sequences were not assigned, what was the number of participants in the study? (note, for example, that the sequence a, b, c is different from the sequence c, b,a.) 20

Answers

Number of possible sequence of 3 in 8  = 8P3 = 8! / (8-3)! =  336
36  were not assigned so  number participants = 300 (answer).
