Answer:

Step-by-step explanation:

Covert 4 3/8 to decimal

$4\dfrac{3}{8}=\dfrac{35}{8}=4.375$

4.375 < 4.5

No. 4 3/8 is less than 4.5

You and your friend get the same magazine. You spend $15 for twelve issues. Your friend pays $1.50 per issue but gets the first

Allushta [10]

He will get 12 issues too. Since he spent 15 dollars in total you would divide that by 1.50 to see how many he actually purchased and it comes out to 10 meaning that he got 10 issues with the money. Now he got two free issues so you would add them to the ones he purchased, so 10 + 2 which would equal 12. So in total he got 12 issues. I hope that helps and wasn't confusing.

Which of the following is the definition for permutation?

Kamila [148]

Answer:

The answer is D. Selections of objects in which the order of the objects matters.

Step-by-step explanation:

Permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement.

The formula for permutation: A permutation is the choice of (r) things from a set of (n) things without replacement and where the order matters. Formula-

$nPr= \frac{n!}{(n-r)!}$

Permutation can be classified in three different categories:

Permutation of (n) different objects (when repetition is not allowed)

Repetition, where repetition is allowed

Permutation when the objects are not distinct (Permutation of multi sets)

PLEASE HELP ME A B C OR D

RoseWind [281]

Answer:

Examine the mathematical expression you're working on. For example, suppose you're given 5x + 3. There are two terms here, 5x and 3. Look for the variable. In this case, x is the variable. In your case its c

Find the numerical coefficient of x. Remember to look for the number before the variable. In this case, 5 is the numerical coefficient. The term 3 is a constant and is separated from the variable by a plus sign.

Keep an eye out for negative coefficients. For example, suppose you're given the statement -y + 7 + 98. You would first identify the variable, y.

Look for the numerical coefficient of y. In this case, a "1" is implied before the variable, but it's negative in this instance. Therefore, the coefficient of y is negative 1.

Jim invested $4000 in two accounts. The first account paid 10% interest. the second account paid 2% interest. At end of the year

Darina [25.2K]

Answer: the amounts are $1400 and $2600

Step-by-step explanation:

Let x represent the amount in the first account.

Let y represent the amount in the second account.

Jim invested $4000 in two accounts. It means that

x + y = 4000

The interest on the amount invested is simple interest. The formula for simple interest is expressed as

I = PRT/100

Where

I is the interest

P is the principal or initial amount

R is the interest rate

T is the time

Considering the first account,

P = x

R = 10%

T = 1

I = (x × 10 × 1 )/100 = 10/100 = 0.1x

Considering the second account

P= y

R = 2%

T = 1

I = (y × 2 × 1)/100 = 0.02y

At end of the year, he had earned $192 in interest. It means that

0.1x + 0.02y = 192 - - - - - - -1

Substituting x = 4000 - y into equation 1, it becomes

0.1(4000 - y) + 0.02y = 192

400 - 0.1y + 0.02y = 192

- 0.1y + 0.02y = 192 - 400

-0.08y = -208

y = -208/0.08 = $2600

x = 4000 - y

x = 4000 - 2600 = $1400
