at the school fair, of the people are under 16 years old. one-third of the people are teachers. if there are at least 21 one tea
Diano4ka-milaya [45]
Hello there!

Your correct answer will be 35 people under 16.

You know that 1/3 of the people are teachers, which means that 2/3 of people are left. Now, you need to get to the decimal value (.667). Make that number 1.667, because there will not be less teachers than students. Now, multiply:

1.667 x 21 = 35

There you go!

I need someone really good at math to help me please!! A home is purchased for $394,000 with a 14% down payment. Find the monthl
julia-pushkina [17]

9514 1404 393

Answer:

  $2300.01

Step-by-step explanation:

The down payment is 14% of $394,000, so is ...

  0.14 × $394,000 = $55,160

This means the principal amount of the loan is ...

  $394,000 -55,160 = $338,840

__

The amount of the monthly loan payment is given by the amortization formula ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the principal amount, r is the annual interest rate, and t is the number of years. Filling in the values, we have ...

  A = $338,840(0.072/12)/(1 -(1 +0.072/12)^(-12·30))

  = $338,840(0.006)/(1 -(1.006^-360)) = $2300.01

The monthly payment is $2300.01.

Factor completely: 3a^2 + 5a − 12
jarptica [38.1K]
Your answer would be the second option, (3a - 4)(a + 3).

We can see that this is the correct answer as if we expand it using FOIL, we get 3a² + 5a - 12:

(3a × a) + (3a × 3) + (-4 × a) + (-4 × 3) = 3a² + 9a - 4a - 12
= 3a² + 5a - 12.

I hope this helps!
