Sabric's claim is correct because in a number line -3.613 is closer to the zero than -3.63.
_______________________________________________________________
      -3.63                                       -3.613                                    0          1          2..

Also the place value can tell you which is greater:       3.613
Notice the 1 and the 3:                                                     3.63
The smaller number when using negatives is closer to the zero than the bigger one.

Isabel found 54 coins at the bottom of her backpack. when she looked, she noticed they were only nickels and dimes. Isabel count
goblinko [34]

She had 23 nickles and 31 dimes

Step-by-step explanation:

The given is:

  • Isabel found 54 coins at the bottom of her backpack
  • She noticed they were only nickels and dimes
  • Isabel counted the coins and they totaled $4.25

We need to find how many nickels and dimes she had

Assume that the number of nickels is x and the number of dimes is y

∵ Isabel had 54 coins

∵ The number of nickels is x

∵ The number of dimes is y

∴ x + y = 54 ⇒ (1)

∵ 1 nickle = 5 cents

∵ 1 dime = 10 cents

∵ The coins totaled $4.25

- Change the dollars to cents

∵ 1 dollar = 100 cents

∴ $4.25 = 4.25 × 100 = 425 cents

- Multiply the number of nickles by 5 and the number of dimes

  by 10, add the two products and equate the sum by 425

∴ 5x + 10y = 425 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -10 to eliminate y

∵ -10x - 10y = -540 ⇒ (3)

- Add equations (2) and (3)

∴ -5x = -155

- Divide both sides by -5

∴ x = 23

Substitute the value of x in equation (1) to find y

∵ 23 + y = 54

- Subtract 23 from both sides

∴ y = 31

She had 23 nickles and 31 dimes

Answer:

option B

Step-by-step explanation:

Regression models are not usually made use of if the need is to predict population, which has to do with number present as well as the stocks of large companies and so on, reason being that their variable levels or confidence interval are usually out of range of those used for a regression

She can choose three books in 54 ways

What is permutation?

Permutation is a technique involving in which a set or number of things can be ordered or arranged. We use permutation to solve and compute answers

We are given that, Josephine has three chemistry books, three history books, and nine statistics books

She has to choose one from each subject

Firstly She has 3 chemistry books

This can be selected in 3 ways

Then She has 3 history books

This can be selected in 3 ways

Ans finally she has 9 statistics books

This can be selected in 9 ways

Hence total ways in which she can select 3 books is 3*3*9= 54 ways

Hence in 54 ways she can choose three books

Simplify (3x)-1. A. 81x^4. B. 4x^6. C. 1/3x. D. 1/x^6
elena55 [62]
If you mean: (3x)^-1

When you have a power to a negative number (1 in this case), place the power on the numerator, with the base in the denominator.

(3x)^-1 = 1/3x

1/3x, or C) is your answer


hope this helps
