Answer:

1,171,862

Step-by-step explanation:

Original equation: 5^7 * 15-8-5

Remember the PEMDAS rule --> in this case the exponents are first.

5^7= 5*5*5*5*5*5*5 = 78,125

=  78,125*15-8-5

The next step to this problem is multiplication because you are starting from left to right and its after the exponents.

= 1,171,875-8-5

The last 2 steps is to subtract (from left to right)

= 1,171,867-5

= 1,171,862

Hope this helps!!!

13. \:\:\: 15. \:\:\: 195

14.\:\:\: 42 \:\:\: 588

15. \:\:\: x. \:\:\: 15x

16. \:\:\: 10. \:\:\: 160

17. \:\:\: 3. \:\:\: 51

. n=70+x. \sum=994+15x

we have

mean=sum/n

14.44=\bold{\frac{\sum}{n}}

14.44=\bold{\frac{994+15x}{70+x}}

doing crisscrossed multiplication

(70+x)*14.44=994+15x

1010.8+14.44x=994+15x

15x-14.44x=1010.8-994

0.56x=16.8

x=16.8/0.56

x=30

Keiko+has+a+health+insurance+premium+of+$3298+annually. +if+her+employer+pays+90%+of+the+premium,+how+much+does+she+pay+annually
soldier1979 [14.2K]

The amount Keiko pays annually is $329.8

To answer the question, we need to know the amount Keiko pays annually

<h3>How to calculate how much Keiko pays annually.</h3>

Since Keiko health insurance premium annually is $3298 and if his employer pays 90% of the premium, we want to know how much Keiko pays.

Since the employer pays 90% of the premium, the employer pays x = 90% of $3298

= 0.9 × 3298

= $2968.2

So, the amount Keiko pays annually is y = premium - amount employer pays, x

= $3298 - $2968.2

= $329.8

So, the amount Keiko pays annually is $329.8

Harlamova29_29 [7]
<span>Each piece length will be 1/8 part of the whole piece, so as the total length is 9 yards then we will have that the lengh of each piece is one and eighth yard. The division expression is as follows: Piece length = 9 * 1/8 = 9/8 = (8+1)/8 = 8/8+1/8 = 1 + 1/8 = 1 + 0.125 = 1.125 yards</span>
