The decimal equivalent of 4 thousands, 9 hundreds, 2 tens, and 6 ones is 4926. This is calculated by adding the value of each quantity: 4000 (from the 4 thousands), 900 (from the 9 hundreds), 20 (from the 2 tens), and 6 (from the 6 ones)

The question is asking for the decimal equivalent of the quantity represented by 4 thousands, 9 hundreds, 2 tens, and 6 ones. To determine the answer, you would simply total the value of each quantity: 4 thousands equals 4000, 9 hundreds equals 900, 2 tens equals 20, and 6 ones equals 6. When you add these values together (4000 + 900 + 20 + 6), you get the total value of 4926 which is the decimal equivalent that we are looking for.

Answer:

x=y-4

Step-by-step explanation:

y=x+4

-4

y-4=x

Answer:

Option A.

Step-by-step explanation:

y = x + 4

As we know if we perform a similar operation on both the sides of the equation it doesn't affect the parent equation.

So we subtract 4 on both sides of the equation

y - 4 = (x + 4) - 4

x = y - 4

Therefore, option A. will be the answer.

To find the possible lengths of the garden, use the perimeter formula and solve the inequality x <= 27 ft.

To find the possible lengths of your garden, you need to determine the perimeter of the garden. Since you have at most 54 ft of fence, the perimeter must be less than or equal to 54 ft.

Let's assume the length of your garden is 'x', then the width would be (54 - 2x)/2.

The perimeter formula is P = 2L + 2W, so substituting the values we have, 2x + 2[(54 - 2x)/2] <= 54.

Simplifying this inequality, we get x + 54 - 2x <= 54. Solving for 'x', we get x <= 27.

Therefore, the possible lengths of your garden are any value less than or equal to 27 ft.

The shape described is a square, having four sides, two pairs of parallel sides, and four right angles, making it two sides fewer than a hexagon.

The shape you are referring to is one with four sides, two pairs of parallel sides, and four right angles. A hexagon has six sides, so a shape with two fewer sides would have four sides. This description matches that of a rectangle. However, since all angles are right angles, which is 90 degrees, this particular rectangle is also a square. Therefore, the pattern block shape you are asking about is a square, which fits the criteria of having two fewer sides than a hexagon, two pairs of parallel sides, and four right angles.

Answer: 0.35

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 35% as the ratio 35 to 100 or 35 ÷ 100. Remember that dividing by 100 moves the decimal point 2 places to the left. Therefore, 82 ÷ 100 would move the decimal point 2 places to the left which would give us .35 or 0.35.

35% can be written as the decimal 0.35.

The decimal equivalent of 35% is 0.35 .

Given,

To simplify the expression[tex]\( 10x - 12y + 8 + 12y \)[/tex] by combining like terms, follow these steps:

1. Combine the terms with the same variable:

[tex]\[ 10x - 12y + 8 + 12y \] \[ = (10x) + (-12y + 12y) + 8 \] \[ = 10x + 0y + 8 \] \[ = 10x + 8 \][/tex]

Answer:

a)480

b)960

c)1440

Step-by-step explanation:

We are given the following information:

Number of oranges in a box = 24

a)Boxes ordered by Lee for his store = 8

Number of boxes ordered by Lee for his restaurant = 12

Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box

[tex]= (8+12)\times 24 = 20\times 24 = 480[/tex]

b) Now Mr. Lee doubled his order for next week.

Boxes ordered by Lee for his store = 16

Number of boxes ordered by Lee for his restaurant = 24

Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box

[tex]= (16+24)\times 24 = 40\times 24 = 960[/tex]

c) Total number of oranges ordered =

[tex](20\times 24) + (40\times 24) = (20+40)\times 24 = 1440[/tex]

Therefore, total 1440 oranges were ordered by Mr. Lee.

The simplified expression is -11/40.

The expression -3/8 - 1/10 can be simplified by following these steps:

1. Find a common denominator for the two fractions. The smallest number that both 8 and 10 can divide into is 40.

2. Rewrite the fractions using the common denominator.

  -3/8 = -15/40
  -1/10 = -4/40

3. Subtract the rewritten fractions.

  -15/40 - (-4/40) = -15/40 + 4/40 = -11/40

Therefore, the simplified expression is -11/40.

She uses 243 beads for the 5th string.

Step-by-step explanation:

In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:

The second uses 9, 3 * 3 = 9

The third uses 27, 9 * 3 = 27

The fourth uses 81, 27 * 3 = 81

And the 5th uses 243, 81 * 3 = 243.
