6224 Brand X residents and 9335 Brand Y residents

Step-by-step explanation:

Total number of residents in the survey=15559

Residents that prefer Brand X=40%

Residents that prefer Brand Y=60%

Population sample?

Residents that prefer Brand X= 40/100 ×15559 =6223.6⇒6224 residents

Residents that prefer Brand Y= 60/100 × 15559 =9335.4⇒⇒9335 residents

Answer: B

Step-by-step explanation:

Based on the fact that the shape of the given square is dilated with a scale factor, the result would be the first square with a dimension of 3.

The Dilation is to be with a scale factor of 1/3.

This means that the dimensions on the new shape will be:

= Dimensions on original shape x scale factor

= 9 x 1/3

= 9/3

= 3

Dilation does not change the shape of an object so the result of the Dilation would be the first square with a side measurement of 3.

Answer:

  17 bars

Step-by-step explanation:

Peter wants to compute the maximum number of bars he can load safely if the load limit of 1200 kg and the bar weight of 60 kg are each rounded to the number of significant digits those numbers have.

The error in a rounded number is assumed to be as much as half of the least significant digit of the number.

Peter's load limit may actually be as low as ...

  1200 kg - (1/2)(100 kg) = 1150 kg . . . . . . . 1200 is rounded to nearest 100

Peter's bar weight might be as high as ...

  60 kg + (1/2)(10 kg) = 65 kg . . . . . . . . . . . 60 is rounded to nearest 10

If Peter has maximum-weight bars and does not want to exceed the minimum his load limit might be, the number of bars he can load is ...

  (1150 kg) / (65 kg/bar) ≈ 17.7 bars

The greatest number of bars Peter can load safely is 17.

since W is the midpoint, that simply means that both halves are twins, so

The length of segment VY, represented by "a," is 25x - 21.

To find the length of segment VY, we can use the fact that W is the midpoint of VY. The midpoint of a line segment divides it into two equal parts. Therefore, the length of VW plus the length of WY equals the length of VY.

Let VY be represented by "a." Then, according to the midpoint property:

VW + WY = VY

Substitute the given expressions for VW and WY:

(9x + 7) + (16x - 28) = a

Now, combine like terms:

25x - 21 = a

So, the length of segment VY, represented by "a," is 25x - 21.

Answer: 53.44

Step-by-step explanation:

Answer:

53.4 repeating

Step-by-step explanation:

Step 1:Start by setting it up with the divisor 9 on the left side and the dividend 481 on the right side like this:         9⟌481

Step 2:The divisor (9) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:    0    9⟌481

Step 3:Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.     0    9⟌481   0  

Step 4:Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.     0    9⟌481   -0      4  

Step 5:Move down the 2nd digit of the dividend (8) like this:    0    9⟌481   -0      48 

Step 6:The divisor (9) goes into the bottom number (48), 5 time(s). Therefore, put 5 on top:    05   9⟌481   -0      48 

Step 7:Multiply the divisor by the result in the previous step (9 x 5 = 45) and write that answer at the bottom:    05   9⟌481   -0      48     45 

Step 8:Subtract the result in the previous step from the number written above it. (48 - 45 = 3) and write the answer at the bottom.    05   9⟌481   -0      48    -45      3 

Step 9:Move down the last digit of the dividend (1) like this:    05   9⟌481   -0      48    -45      31

Step 10:The divisor (9) goes into the bottom number (31), 3 time(s). Therefore put 3 on top:    053  9⟌481   -0      48    -45      31

Step 11:Multiply the divisor by the result in the previous step (9 x 3 = 27) and write the answer at the bottom:    053  9⟌481   -0      48    -45      31     27

Step 12:Subtract the result in the previous step from the number written above it. (31 - 27 = 4) and write the answer at the bottom.    053  9⟌481   -0      48    -45      31   - 27      4

You are done, because there are no more digits to move down from the dividend.The answer is the top number and the remainder is the bottom number.Therefore, the answer to 481 divided by 9 calculated using Long Division is: 53 4 Remainder

2x = 28

x = 14

Answer: $14

Answer:

14

Step-by-step explanation:

Tie is X

Shirt is x + 29

Answer: 8 1/2 cups of flour

Step-by-step explanation:

You can look at this solution as x being the number of batches of biscuits.

1x = 1 batch of biscuits

1x = 3 2/5 cups of flour, or 17/5 cups of flour

We need to make 2 1/2 batches, restated as 5/2 batches.

This can be restated as 5/2x.

To determine our answer, we multiply x by 5/2.

5/2*(1x) = 5/2*(17/5)

5/2x = 85/10

Simplify.

85/10 = 8 5/10 or 8 1/2 cups

8 1/2 cups of flour are needed to make 2 1/2 batches of biscuits.

The minuend and the subtrahend of 696 - 275 can be decomposed to give;

600 + 90 + 6

-

200 + 70 + 5

400 + 20 + 1

The decomposition into place values is chosen because of ease of reinforcing knowledge.

The decomposition method of subtraction involves decomposing the subtrahend, which is the smaller number and the place value of the numbers can be simply subtracted from the minuend.

In the subtraction, 696 - 275, the minuend is 696, while the subtrahend is 275.

Decomposing the subtrahend, gives;

275 = 200 + 70 + 5

Decomposing the minuend, gives;

696 = 600 + 90 + 6

The subtraction expression in the question, 696 - 275 gives;

696

-275

The above can therefore be decomposed as follows;

600 + 90 + 6

-

200 + 70 + 5

400 + 20 + 1

400 + 20 + 1 = 421

Therefore;

696 - 275 = 421

The reason the decomposition into place values of each digit is chosen is so as to make use of the easier understanding of subtracting numbers that are multiples of 10.

the central value of a set of data is expressed by the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data. The average of 2, 3, and 4 is, for instance, (2+3+4)/3 = 9/3 = 3. The center value of 2, 3, and 4 in this instance is 3, thus. Finding the mean value of a bunch of numbers is the definition of average.

1. The number of edible portions (EP) is 64.

2. The food cost per portion = $0.75 per portion.

The number of edible portions can be determined by first converting the case weight in pounds into ounces.

There are 16 ounces in a pound. 20 pounds will equal 320 ounces by multiplication (16 x 20).

Then, divide 320oz by 5oz to determine the number of portions.

Yield:                      90%

Purchase Unit:       10 boxes = 1 case

Case Weight:        20 lbs

Case Cost:           $48.00

Portion Size:         5oz

1lb = 16oz

20lbs = 320oz (20 x 16)

Edible portions (EP) = 64 (320oz/5oz)

Food cost per portion = $0.75 per portion ($48/64).

Thus, the number of edible portions is 64 with the food cost per portion as $0.75.
