Answer:

$27.99 interest.

Step-by-step explanation:

Use the formula for Compound interest = P(1 + r/n)^t  . Here n = 365 (number of days in a year), r = annual rate as a decimal and t = the number of days, P = 8000.

Amount after 15 days = 8,000(1 + 0.085/365)^15

= $8027.99.

Car dealerships claim to make most of their money from servicing cars. In a certain month, an Acura dealership sold fifteen less
MA_775_DIABLO [31]

Answer:

New cars sold = 20,

Used cars sold = 25

Cars serviced = 290

Step-by-step explanation:

In a month they sold fifteen less used cars than twice the number of new cars.

Lets say 'x' number of new cars were sold, then:

The number of used car sold is:

2\times x-15=2x-15

In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:

12\times x+50=12x+50

Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:

x+(2x-15)+(12x+15)=335

Solving for 'x' we get:

x+2x+12x-15+50=335

15x+35=335

15x=335-35=300

x=\frac{300}{15}=20

Therefore, the number of new cars sold in that month is 20.

Number of used car sold =2x-15=2\times 20-15=40-15=25

Number of cars serviced =12\times x+50=12\times20+50=240+50=290

We can also cross check by summing them up:

290+25+20=335

Help me please and thank you
posledela

Answer:

m∠N = 85°

Step-by-step explanation:

<u>Properties of a parallelogram</u>

  • opposite sides are parallel and equal in length
  • opposite angles are equal
  • interior angles that lie on the same side of the transversal are supplementary - their sum is 180°

Therefore,

m∠M + m∠N = 180°

⇒ 95° + m∠N = 180°

⇒ m∠N = 180° - 95°

⇒ m∠N = 85°

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

<u>Additional calculations</u>

m∠M = m∠P = 95°

m∠N = m∠L = 85°

MN = LP

ML = NP
