Can someone help me round up decimals plzz
boyakko [2]
In this situation, 0.782 would be rounded to 0.8

how to round a decimal: take the underlined number and look to the number located to the RIGHT of the underlined number, if the number to the right of the underlined number is 4 or less you leave the underlined number as is - but if the number right to underlined number is 5 or greater you round the underlined number up by one

ex. 1.83 [round to the nearest tenth]

answer: 1.80

instead of keeping the 3 [hundredth] you turn it into a 0.

The area of a rectangle is 24396
Oksanka [162]

Answer: Length = 642 cm

Concept:

Here, we need to know the idea of how to find the area of a rectangle.

Area (rectangle) = l × w

l = length

w = width

Solve:

<u>Given information</u>

A = 24396 cm²

w = 38 cm

<u>Given expression</u>

A = l × w

<u>Substitute values into the expression</u>

24396 = l × (38)

<u>Divide both sides by 38</u>

24396 / 38 = l × 38 / 38

\boxed{l=642}

Hope this helps!! :)

F(x)=x^+4x+2 what is the average rate of change from x=3 to x=5
mars1129 [50]

Answer:

12

Step-by-step explanation:

f(x)=x^+4x+2 First, let's evaluate when x=3, x=4 and x=5.

f(3) = 3²+4(3)+2 = 9 + 12 + 2 = 23

f(4) = 4²+4(4)+2 = 16 + 16 + 2 = 34

f(5) = 5²+4(5)+2 = 25 + 20 + 2 = 47

Now, let's find the rate of change.

34 - 23 = 11

47 - 34 = 13

Finally, the average rate of change.

(11 + 13) / 2 = 12
