You want to buy a $219,000 home. You plan to pay 10% as a down payment, and take out a 30 year fixed loan for the rest.

vovangra [49]

Answer:

see explanation

Step-by-step explanation:

I assume you need to find the 10% and also the amount per year maybe?

so, you will pay 21,900 dollars upfront

219000-21900=197100

219000*1/10=21900, which is ten percent.

197100=30x, x being money paid per year in this case

divide both sides by 30

6570=x

You will pay 6,570 each year for this house. You can continue to divide to find monthly payments. or quarterly payments. Divide by 12 to find monthly payment and divide by 4 to find quarterly

After 3 minutes, a submarine had descended to −320 feet. After 8 minutes, the submarine had descended to −420 feet. Assuming a l

LiRa [457]

Answer:

$d(t) = -20t - 260$

Step-by-step explanation:

The depth function is:

$d(t) = mt + b$

After 3 minutes, a submarine had descended to −320 feet.

This means that $d(3) = -320$ . So

$d(t) = mt + b$

$-320 = 3m + b$

After 8 minutes, the submarine had descended to −420 feet.

This means that $d(8) = -420$ . So

$d(t) = mt + b$

$-420 = 8m + b$

From the first equation:

$b = -320 - 3m$

$-420 = 8m + b$

$-420 = 8m - 320 - 3m$

$5m = -100$

$m = \frac{-100}{5}$

$m = -20$

And

$b = -320 - 3*(-20) = -260$

$d(t) = -20t - 260$

To mix weed killer with water correctly it is necessary to mix 6 teaspoons of weed killer with 2 gallons of water. Find how many

igomit [66]

The correct proportion for mixing weedkiller with water is;

$6\text{tsp:}2\text{gal}$

When the entire box contains 12 teaspoons of weedkiller, we would now have;

$\begin{gathered} \frac{6}{2}=\frac{12}{x} \\ \text{Where;} \\ x=\text{gallons of water} \\ \text{Cross multiply and we'll have;} \\ x=\frac{12\times2}{6} \\ x=4 \end{gathered}$

ANSWER:

To mix 12 teaspoons of weedkiller, 4 gallons of water is needed.
