How do you round an irrational number to the nearest hundredth

Mathematics
1 answer:
MariettaO [177]3 years ago
7 0
To round to the nearest cent, nearest penny, or nearest hundredth, you will need to locate the hundredths place. Then look at the digit to the right. If it is 5 or above, the number in the hundredths place will be increased by 1 and all the rest of the numbers after it are dropped. If the number is 4 or below, you leave the digit in the hundredths place alone and drop all the rest of the numbers after. 

<span>Just remember, if the problem asks you to round to the nearest hundredth, make the end result look like money, meaning only two digits after the decimal point!</span>

Answer:

x = 2, y = -1.

Step-by-step explanation:

2x + y = 3

x  -   y  = 3

Adding the 2 equations eliminates y:

3x = 6

x = 2.

Substitute for x in the first equation:

2(2) + y = 3

y = 3 - 4

y = -1.

Check the results by substitution in equation 2:

2 - (-1)

= 2 + 1 = 3 .

Checks OK.

Can i please get help with this question?
Aleonysh [2.5K]

1,5 . n = 13,65


We know:


1,5=\frac{15}{10}

and

13,65=\frac{1365}{100}


So,


\frac{15}{10}.n=\frac{1365}{100}


Pass \frac{15}{10} as division.


n = \frac{\frac{1365}{100}}{\frac{15}{10}}


Btw, we also know:


\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}


So,


n = \frac{\frac{1365}{100}}{\frac{15}{10}}

n = \frac{1365.10}{100.15}

n = \frac{13650}{1500}

n = \frac{91}{10}

n = 9,1

The average weight of 3 containers A,B and C is 3.2kg. Container A is twice as heavy as container B. Containers B is 400 g heavi
dlinn [17]

Answer:

The weight of container C is 2.1kg.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the weight of container A.

y is the weight of container B.

z is the weight of container C.

The average weight of 3 containers A,B and C is 3.2kg.

This means that the total weight is 3*3.2 = 9.6kg. So

x + y + z = 9.6

Container A is twice as heavy as container B.

This means that x = 2y.

Containers B is 400 g heavier than container C.

400g is 0.4kg. So

This means that y = z + 0.4, or z = y - 0.4

Replacing y and z as functions of x in the first equation:

x + y + z = 9.6

2y + y + y - 0.4 = 9.6

4y = 10

y = \frac{10}{4} = 2.5

Container C

z = y - 0.4 = 2.5 - 0.4 = 2.1

The weight of container C is 2.1kg.
