What is 8.246 rounded to the nearest tenth

Answers

Answer 1

Answer:

Actually the answer is 8.2

When rounding numbers, look for the number they are asking you to round to the nearest. In this case it's the tenths place.

8.246 the 2 is in the tenths place. Look at the number to the right of the 2.

8.246 the 4 is less than 5 so you have to round down. So therefore your answer is 8.2

Hope this helps. :)

Answer 2

Answer: 8.3

you round up the with the thousandths place because it is over 5.
now, the 4 in the hundredths place becomes a 5, so you round up the tenths place.
the 2 becomes a 3.

Hich expression is rational? a. 4.121221222… b.square root of 36 c. square root of 21 d.1.192744502…

Answers

Answer: The correct option is (B) square root of 36.

Step-by-step explanation: We are given to select the correct number that is irrational.

RATIONAL NUMBER: The digits after the decimal are either terminating or repeating.

IRRATIONAL NUMBER: The digits after the decimal are non-repeating and non-terminating.

Option (A) is 4.121221222 . . .

Here, the digits after the decimal are non-repeating and non-terminating. So, the given number is irrational.

Option (B) is square root of 36, which is equal to 6.

6 = 6.00.

Here, the digits after the decimal are terminating. So, the given number is rational.

Option (C) is square root of 21.

We know √21 = 4.5825756 . . .

Here, the digits after the decimal are non-repeating and non-terminating. So, the given number is irrational.

Option (D) is 1.192744502 . . .

Here, the digits after the decimal are non-repeating and non-terminating. So, the given number is irrational.

Thus, the rational number is square root of 36.

Option (b) is correct.

A rational number is any number that can be expressed as the quotient of fraction of two integers.So the answer is b.square root of 36 = √36=6 because 6 is the quotient of 6/1

A hexagonal pyramid is cut by a plane as shown in the diagram. What is the shape of the resulting cross section?

Answers

The resulting cross section would have the same shape as the base which is a hexagon.

Three dimensional figure

A three dimensional figure is a solid with length, breadth and height. A pyramid is a three-dimensional shape with a base that is a polygon and faces which are triangular.

From the image, the resulting cross section would have the same shape as the base which is a hexagon.

Cross section is a surface that is exposed after slicing or making a cut through an object. If a hexagonal pyramid is cut horizontally then the cross section should be an hexagon as well since the base is a hexagon. However, when it is cut vertically the resulting shape would be a triangle.

The number of grocery items on two grocery lists differs by 7. the total number of items is 33. How many items are on each list?

Answers

Answer:

There are 20 items on one grocery list and 13 items on second grocery list.

Step-by-step explanation:

We are given that there are two grocery list and one of the grocery list have seven things less than the other grocery list.

Let x be the number of items on one grocery list.

Then, by the given information, there are x -7 items on the second grocery list.

The total number of items on both the list are 33.

Then, according to the question,

$x + (x-7) = 33\n2x - 7 = 33\n2x = 40\nx = 20$

Thus, there are 20 items on one grocery list and (20 -7) = 13 items on second grocery list.

x+ x+7=33
2x+7=33
2x=26
x=13
x+7=20
13+20=33

one list has 13 items, the other list has 20 items
