Write a definition of rounding in your own words???

Answers

Answer 1
Answer: Rounding is when you have at least a two digit number (26 for example) and if the number the right (6) is 5 or above  then the number goes up one unit, (therefore 26 becomes 27). But if the number (22) to the right is 4 or lower, then the number to the right stays the same, but the number to the right becomes a zero, (making 22 now 20).
Answer 2
Answer: Rounding is when you make your number go higher or lower based on the given information.

Carson went to pick apples at an orchard.he gave one-third of his apples to his friend Nathan.then he gave one-half of what he had to his friend Nikki.on his way home he dropped one-fourth if what he had left,so that he only had 9 for him and his family.how many apples did Carson pick originally?

Answers

Answer:

36

Step-by-step explanation:

Carson had x number of apples to start with.

He gave 1/3 to Nathan. Now Carson has (2/3)x apples left.

He gave 1/2 of what was left to Nikki. Now Carson has (1/2)(2/3)x = (2/6)x = (1/3)x apples.

On the way home, he dropped 1/4, so he has 3/4 of the last amount he had, and the number is 9.

(3/4) * (1/3)x = 9

3/12 x = 9

1/4 x = 9

x = 36

Answer: He picked 36 apples.

Check:

Start with 36 apples.

Give 1/3 to Nathan. Now Carson has 24 apples.

Give 1/2 to Nikki. Now Carson has 12 apples.

Drop 1/4. 1/4 of 12 is 3. 12 - 3 = 9.

Hew only had 9 apples left, so 36 is correct.

Answer:

36 apples

Step-by-step explanation

Step 1  = he dropped 1/4  and was left with 9  

Finding 1/3 one third of 9 = 3.

Then 9 +3 = 12

Step 2 He parted with 1/2 and was left with 12

12x2=24

Step 3 He parted with 1/3 and was left with 24

= 12+ 12 + 12  = 36    Where 1/3 of 36 = 24

A water cup is shaped like a cone. It has a diameter of 3 inches and a slant height of 5 inches. About how many square inches of paper do you need to make a cup? Use 3.14 to approximate pi.24 square inches


31 square inches


47 square inches


52 square inches

Answers

So basically, what this question is asking you for is the surface area of the entire cone.
To find it, we can use the formula:
SA = 3.14*r*l+3.14*r^2, where r is radius and l is lateral height
Now, all we have to do is plug all of the given values into the equation

Therefore, the equation we get is:
SA = 3.14*1.5*5 + 3.14*1.5^2
If we simplify, we find that the surface area is equal to 30.615
If we round this number to the nearest whole number, we get 31 square inches

Therefore the answer is 31

Hope this helped!! :D

Answer:

24 square inches

Step-by-step explanation:

Radius is half of diameter. Therefore 1.5in

Using formula

3.14x1.5x5=23.55

Round up to 24

7 times what equals 31

Answers

Lets say the number we are solving for is a

\sf{ 7 * a = 31}

Divide 7 on both sides

\sf{ (7 * a)/(7) = (31)/(7)}

\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\huge{\sf{a =  (31)/(7)}}}}}}}}}}}}}}}}}}}}}}}}}}}}

7 times approximately 4.4 equals approximately 31 .

To find the number that, when multiplied by 7, equals 31, we need to solve the equation :

7 * x = 31

Here, x represents the unknown number we are trying to find .

To isolate x, we divide both sides of the equation by 7 :

( 7x ) / 7 = 31 / 7

Simplifying, we have :

x = 31 / 7

Calculating the division, we find :

x ≈ 4.4285714

x = 4.4

7 * 4.4 = 31

Therefore, 7 times approximately 4.4 equals approximately 31 .

Show how to multiply 46.93×1.8

Answers

To start off this is multiplication and not addition nor subtraction where you have to line up your numbers like 46.93+ 1.98No, instead you put them in any order such as46.93x. 1.98---------------37544421370+ 469300------------------92.9214 ------> This is your answer!1)Multiply the 3 in 46.93 to the 8 in 1.98 which is 24. 2) Then you multiply the 9 in 46.93 to the 8 in 1.98 which gives you 72 and don't forget to add the 2 from 24. You get 74. 4)You then multiply the 6 in 46.93 to the 8 in 1.98 and you get 48, add the 7 from 74, and you get 55. 5) You multiply the 4 in 46.93 to the 8 in 1.98 and you get 32, plus the 5 from 55 and you get 37. Your first answer should be 37544.6) After you get this answer, you add a zero underneath the 4 in the one's place from your previous answer. 7) This step might be a little hard to remember, but you do the same procedure as you were doing in steps 1-6. This time on the other hand, you multiply each value in 46.93 to the 9 in1.98. 8)After completing those exact steps, your secondary answer should be 421370. 9) Once having this answer, you multiply 46.93 to the 1 in 1.98 and your third answer should be 469300. 10) The next step is to add up all three of your answers together and you get the final answer. You should be getting 929214. 11) The last and final step is to count the spaces of decimals your multiples' have which are 4, and you move 4 spaces to the left and you get 92.9214.

Final answer:

To multiply 46.93 and 1.8, you treat 1.8 as 18, perform the multiplication, and then reinsert the decimal in the right spot. After carrying out these steps, you'll arrive at the result of 84.474.

Explanation:

To multiply the numbers 46.93 and 1.8, you can use the standard multiplication algorithm. Start by thinking of 1.8 as 18, but remember to put the decimal back in the result. Here are the steps:

  1. Multiply 18 by 3 (the number in the hundredths place of 46.93). The result is 54. Write down 54.
  2. Multiply 18 by 9 (the number in the tenths place of 46.93) and add the carried over 5 from the last step. The result is 167. Write down 167, but shift it one place to the left.
  3. Multiply 18 by 6 (the number in the ones place of 46.93). Write this down, shifted two places to the left.
  4. Multiply 18 by 4 (the number in the tens place of 46.93). Write this down, shifted three places to the left.
  5. Add up all the lines. The result should be 84474.
  6. Count how many decimal places are in the numbers you are multiplying. In this case there are two (46.93 has two, 1.8 has one). So put a decimal in your result two places from the right. The final answer is 84.474
