Find three consecutive even intergers whose sum is 72

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
3 0

Answer:

The three numbers are: 22, 24, 26

Consecutive even numbers don't have every number, just the even ones.  So, for example, 40, 42, 44 are three consecutive even numbers.

The sum comes from addition.

Let any of the numbers be x (but, remember that the equations change based on which number you pick):

   Sum = (x) + (x+2) + (x+4) = 72

    3x + 6 = 72              (collect like terms)

    3x =  66                 (subtract 6 from both sides)

    x = 22         (I let x=first number)

A shopkeeper marks the price of an article
marin [14]

Answer:

The gain percent made by shopkeeper is 10.5%.

Step-by-step explanation:

Given:

Price at which goods are marked = 30%

Discount on the marked price = 15%

To Find:

Gain percentage of the shopkeeper

Solution:

Let the cost price of the product be = 100

Therefore,

MP = 30 + 100 = 130

Since discount is 15%. thus -

Discount = 15/100 x 130

= 19.5

Selling price = MP - Discount

SP = 130 - 19.5

= 110.5

Profit = SP - CP

= 110.5 - 100

= 10.5

Calculating the gain%

Gain% = 10.5/100 x 100

= 10.5

Answer: The gain percent made by shopkeeper is 10.5%.

For a segment of a radio​ show, a disc jockey can play 6 records. If there are 11 records to select​ from, in how many ways can
saul85 [17]

Answer:

The records can be select in 332,640 ways.

Step-by-step explanation:

Consider the provided information.

There are 11 records to select from and a disc jokey can play 6 records.

Here, we need to find the number of permutation of n = 11 records taken r = 6 at a time.

Use the formula: ^nP_r=\frac{n!}{(n-r)!}

Substitute the respective values in the above formula.

^{11}P_6=\frac{11!}{(11-6)!}

^{11}P_6=\frac{11!}{5!}

^{11}P_6=\frac{5!\times6\times7\times8\times9\times10\times11}{5!}

^{11}P_6=332640

Hence, the records can be select in 332,640 ways.
