Describe a way that someone could estimate the length of a book

Answers

Answer 1

Answer:

Answer with explanation:

→The best estimation of a book will be in terms of CM(Centimeter) or Feet.

→We Should use "Centimeter Scale or Measuring tape" for this purpose.

→Otherwise, take a thread ,Put one end of thread on one end of book, that is along the longer side, and keep elongating the thread until you reach the other end.Now, with the help of Different kind of Measuring tape,you can find the length of that thread Accurately.And that will be the length of the book.

Answer 2

Answer: Somebody can estimate the length of a book by using a ruler and rounding it to the nearest whole number.

Bonita evaluated 5/6 × 1 2/3 and got an answer of 7/3. How can you tell that her answer is wrong?A. The answer must be less than 5/6.

B. The answer cannot be an improper fraction.

C. 5/6 of a number cannot be greater than the number.

D. The denominator cannot be the same as one of the factors.

Answers

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

$(5)/(6)* 1(2)/(3)\n\n=(5)/(6)* (5)/(3)\n\n=(5* 5)/(6* 3)\n\n=(25)/(18)$

But she gets $(7)/(3)$ as an answer.

As we know that

$(5)/(6)$ of a number cannot be greater than the number.

Because the value of $(5)/(6)$ is 0.84 which is less than 1.

So, $(5)/(6)$ of a number cannot be greater than the number

and

$(7)/(3)=2.34\n\nbut\n\n(25)/(18)=1.38$

1.38<2.34 i.e.

$(25)/(18)<(7)/(3)$

So, Option 'C' is correct.

Convert the mixed number 1 2/3 into an improper fraction first by multiplying the denominator by the whole number part and add the numerator to get the new numerator. Place the new numerator over the old denominator.

5 * 5/6 * 3

Multiply 5 by 5 to get 25.

25/6 * 3

Multiply 6 by 3 to get 18.

25/18

1 7/18

Solve the equation 4 1/5+b= 9 3/5 b=---

and if you could work it out and show me that would help a lot.

Answers

4 1/5 + b = 9 3/5

4 1/5 - 4 1/5 + b = 9 3/5 - 4 1/5
(taking the same amount from each side to keep it balanced)

0 + b = 5 2/5
(subtracting 4 1/5 from each side)

b = 5 2/5

4 1/5+b=9 3/5
convert to improper fraction
21/5+b=48/5
since they both have the same denominators,you can subtract the numerators
b= 48/5-21/5
b=27/5= 5 2/5

hope this helps

I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:

Answers

Answer:

8, 2, 8, 2

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer:

9, 1, 9, 1

2, 8, 2, 8

3, 7, 3, 7

6, 4, 6, 4

Step-by-step explanation:

you would have to have the numbers repeat so it works, for instance, you could do 9,1,9,1 as the first row then 2,8,2,8 as the second row and for the third row you could do 3,7,3,7 and for the fourth row you could do 6,4,6,4 so both the columns and rows add to 20

Xx is 25% of 104, 7 is 10% of yy, and nn is 80% of yy. yy is what percent of (n+y−x)(n+y−x)?

Answers

x = 0.25×104 =26
y = 7 × 10 = 70
n = 70 × 0.8 = 56

(56+70-26)(56+70-26)
⇒(100)(100) = 100

$(70)/(1000)$ × 100 = 7%
