What is 15.833333333333 rounded to the nearest tenth

1 answer:

4 0

To round to the nearest tenth, we need to explain the situation. Rounding to the nearest tenth is rounding the hundredths place, which is 2 places to the right of a decimal, if it is 5 or higher. If our hundredths place is 5 or higher, we can round up our tenths place, which is 1 place to the right of a decimal.
With the information provided, we can work on our question now.
Our number is 15.83~ (endless). Let's look at our hundredths place for a 5 or higher to determine if we can round or not.
Our hundredths place is 3, so we cannot round up our tenths place. This means that our tenths place will remain 8.
Your answer is 15.8.
I hope this helps!

jayden and chandra are cleaning the house. it has 12 rooms, and each room is about the same size. when jayden cleans by himself,

sergij07 [2.7K]

Jayden's work rate is twice Chandra's work rate, and, the rooms cleaned

by Jayden is twice the number of rooms cleaned by Chandra.

Response:

<u>Jayden cleans 8 rooms while Chandra cleans 4 rooms</u>

<h3>Which method can be used to find the number of rooms cleaned by Jayden and Chandra?</h3>

Number of rooms in the house = 12

The time that Jayden takes to clean the house = 6 hours

Time that it takes Chandra to clean the house by herself = 12 hours

Time it takes both of them to clean the house = 4 hours

Required:

The number of rooms that Jayden clean and the number of rooms that

Chandra cleans when they work together.

Solution:

Given that the time it takes Jayden to clean the house is half the time

taken by Chandra.

Therefore;

The number of rooms Jayden cleans in 4 hours is twice the number of rooms cleaned by Chandra, which gives;

Ratio of the number of rooms cleaned by Jayden to the number cleaned by Chandra is 2 : 1

Total number of rooms cleaned = 12

$Number \ of \ rooms \ cleaned \ by \ Jayden = \dfrac{2}{2 + 1} \times 12 = \underline{8 \ rooms}$

The number of rooms cleaned by Chandra = 12 - 8 = <u>4 rooms</u>

For each sequence, find the first 4 terms and the 10th term.<br> a) 3n + 4<br> b) 4n-5

Studentka2010 [4]

Answer:

see explanation

Step-by-step explanation:

To find the first 4 terms substitute n = 1, 2, 3, 4 into the formula, that is

(a)

a₁ = 3(1) + 4 = 3 + 4 = 7

a₂ = 3(2) + 4 = 6 + 4 = 10

a₃ = 3(3) + 4 = 9 + 4 = 13

a₄ = 3(4) + 4 = 12 + 4 = 16

Similarly substitute n = 10 for tenth term

a₁₀ = 3(10) + 4 = 30 + 4 = 34

(b)

a₁ = 4(1) - 5 = 4 - 5 = - 1

a₂ = 4(2) - 5 = 8 - 5 = 3

a₃ = 4(3) - 5 = 12 - 5 = 7

a₄ = 4(4) - 5 = 16 - 5 = 11, and

a₁₀ = 4(10) - 5 = 40 - 5 = 35
