Answer:

1/r^7 + 1/s^12

Step-by-step explanation:

Since there is a negative exponent, the term becomes a fraction. As we do not know the value of the term, it remains in its variable form with a positive exponent

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W

Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2 46.5

5 116. 25

7 162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

$2 \; \rm Jackets =\$ 46.50$

$1 \;\rm Jacket = \dfrac {\$46.50}{2}$

$1 \;\rm Jacket = \$ 23.25$

Now the cost price of 3 jackets is given as,

$3\;\rm Jackets = \$23.25 \times 3$

$3\;\rm Jackets = \$69.75$

Hence we can conclude that the cost price of 3 jackets is $69.75.

Multiple of 4 that have a odd number in the tens place. What value do they have in the ones place

olga nikolaevna [1]

Let us write some multiples of 4.

4,8,12,16,20,24,28,32,36,40.

<h3>We can see that 12,16, 32,36 are the multiples of 4 those have odd numbers 1 and 3 at tens places.</h3>

Now, we need to check the numbers on ones places of those multiples we got.

<h3>Ae can see that at ones places we have 2 and 6 numbers.</h3>

If we find some more mutiples, we get same odd numbers at tens places and same even numbers 2 and 6 at ones places.
