What is the percent change of $15.60 to $11.70?
Rashid [163]

Answer:

percentage change=25% .

Step-by-step explanation:

Given : $15.60 to $11.70    .

To find:  What is the percent change .

Solution: We have given that   $15.60 to $11.70  .

Change = final value - initial value .

Change   = $15.60 - $11.70  

                   =$3.9

percentage change = \frac{change}{original value}*100

                                =   \frac{3.9}{15.60}*100

                                =   \frac{390}{1560}*100.

On dividing both number by 3

percentage change=\frac{130}{520}*100.

percentage change=\frac{1}{4}*100.

percentage change=25% .

Therefore, percentage change=25% .

xz_007 [3.2K]

-np-80 < 60\qquad\text{change the signs}\\\\np+80

------------------------------------------------------

2a-5d=30\qquad\text{subtract 2a from both sides}\\\\-5d=-2a+30\qquad\text{change the signs}\\\\5d=2a-30\qquad\text{divide both sides by 5}\\\\d=0.4a-6

A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble. HINT (See Example 7.] H
Murljashka [212]

Answer:  35

Step-by-step explanation:

Given : A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble.

Total = 4+2+1+3+1=11

To find sets of four marbles include none of the red ones, we need to exclude red marbles when we count the total number of marbles.

Then, the total marbles(exclude red) =11-4=7

Now, the combination of 7 marbles taking 4 at a time is given by :-

^7C_4=\dfrac{7!}{4!(7-4)!}=\dfrac{7\times6\times5\times4!}{4!3!}=35

Hence, the number of sets of four marbles include none of the red ones = 35
