Answer: 8%

i googled it so yea

Answer:

C

Step-by-step explanation:

To do this, let's let the decimal equal n. Thus:

[tex]2.\bar1=n[/tex]

There is only one digit repeating, so let's multiply both sides of the equation by 10:

[tex]21.\bar1=10n[/tex]

Now, subtract n from both sides:

[tex]21.\bar1-n=10n-n[/tex]

On the right, it becomes 9n. However, the left, however, expand, the decimal. In other words:

[tex]21.1111...-2.1111...=9n[/tex]

All of the repeating 1s will cancel out. Thus:

[tex]21-2=9n[/tex]

Subtract:

[tex]19=9n[/tex]

Divide both sides by 9:

[tex]n=\frac{19}{9}[/tex]

And since we set the decimal equal to n originally...

[tex]2.\bar1=\frac{19}{9}[/tex]

And we're done!

Notes:

This is the algebraic way to write a repeating decimal into a fraction. You can, of course, always just use a calculator and guess and check.

It's A. 21/10

What I did to get this. Is i wrote down 2.1 as a fraction: 2.1/1 then multiplied 10 to both the numerator and the denominator. (2.1 x 10)/(1 x 10)=21/10.

I hope this helps. I'm not sure if the "repeating" matters that much to the point of a different answer...

Answer:

so italy is 7,500,000.00 and park is 21,100,000.00, 1997 is 3.40 and 1998 is 2.70

Step-by-step explanation:

Answer:

rounding means if like a number is 254 round it to the nearest hundred which would be 300 because if you can't round it to the nearest hundred you need to round to the nearest 10 which would be 30 plus the 4 on the end round that it would be 300.

Italy: 7,464,000,60

Pakistan: 21,079,00.30

Answer:

0.76

Step-by-step explanation:

Because this question is requiring you to divide a smaller number by a greater one you are going to have decimals or fractions.

The value of the division of the number 43.396 by 57.1 is 0.76.

A procedure of dividing anything into equal halves is called division. It is one of the four fundamental operations in math. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given numbers are 43.396 and 57.1. The value of the division will be calculated as below:-

Division = 43.396 / 57.1

Division = 0.76

Therefore, the value of the division of the number 43.396 by 57.1 is 0.76.

Step-by-step explanation:

7.5 x 10^18: Since the exponent of the scientific notation is positive, move the decimal point  18 places to the right.

AN: 7500000000000000000

7 x 10^27: Since the exponent of the scientific notation is positive, move the decimal point 27 places to the right.

AN: 7000000000000000000000000000

Answer:

7,500,000,000,000,000,000 and 7,000,000,000,000,000,000,000,000,000

Step-by-step explanation:

I would assume that's in scientific notation, so to solve you need to get it out of scientific notation.

Since the exponent is positive, move it that many places to the right.

For the first one, it would be 7,500,000,000,000,000,000.

For the second one, it would be 7,000,000,000,000,000,000,000,000,000.

If the exponent was negative, you would've moved the decimal to the left instead.

Hope this helped. It's the only way I could think of to solve it.

Answer:

a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:

Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71

b) The cost of a ticket for the next game given they have 31 losses is:

Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93

The force needed to accelerate a truck with a mass of 2,000 kg, at a rate of 3 m/s² is 6000 Newtons.

Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.

Given:

The mass of the truck = 2000 kg,

The acceleration of the truck = 3 m/s²,

Calculate the force as shown below,

Force needed for truck = Acceleration of truck × mass of the truck,

Force = 2000 × 3

Force = 6000 N

Hey there!

We can arrange this to say, "90% of the whole is 126."

Thus, we can write an equation, where w is used as a variable to represent the whole.

0.90w=126

Divide by 0.90

w=140

The whole is 140.
