A customer pays $1,100 in state taxes on a newly purchased car. What is the value of the car if state taxes are 8.9% of the valu
Ganezh [65]
The taxes are figured as follows:  0.089(value of car)

Here the taxes are 0.089(value of car) = $1100.

Divide both sides of this equation by 0.089 to determine the value of the car.

value of car = $12359.55, or approx $12360.

I really need help with this, my teacher doesn't really teach and I'm stumped again.​
yarga [219]

Answer:

JMK = 54

JKH = 126

HLK = 90

HJL = 27

LHK = 63

JLK = 27

Step-by-step explanation:

Just use 180 for total angles in each triangle. Vertical angles mean the opposite to 126 is 126 and the other two that make up the inner vertices are (360- 126*2)/2 = 54

So, 126, `16, 54 , 54 are the inner angles in the circle. Just go from there.

There is 7 5/9 wood and people took 3 2/15 pieces. How many more pieces are there
GalinKa [24]
What you have to do is subtract 3 2/15 from 7 5/9. You can also use decimals but that doesn't work all the time since the are infinite numbers (you will see what I mean later on) So what you can do is find the improper fraction of each one, and subtract it from each other. It would be 68/9 - 47/15, which would give you a total of 4 19/45. YOU'RE WELCOME :)

Homework help, one of the few I have
Alex73 [517]

Answer:

x=4 and the solution is not extraneous

Step-by-step explanation:

\sqrt{2x+1}=3 \\\\2x+1=9 \\\\2x=8 \\\\x=4

This solution is not extraneous, because plugging it back in you get:

\sqrt{2(4)+1}=3 \\\\\sqrt{9}=3 \\\\3=3

Hope this helps!
