The coordinates of point A are (-6, -10) and the coordinates of point B are (x,-4). The distance between A to point B is 10 unit

vlabodo [156]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ A(\stackrel{x_1}{-6}~,~\stackrel{y_1}{-10})\qquad B(\stackrel{x_2}{x}~,~\stackrel{y_2}{-4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ 10=\sqrt{[x-(-6)]^2+[-4-(-10)]^2}\implies 10=\sqrt{(x+6)^2+(-4+10)^2} \\\\\\ 10^2=(x+6)^2+(6)^2\implies 100=x^2+12x+36+36 \\\\\\ 100=x^2+12x+72\implies 0=x^2+12x-28 \\\\\\ 0=(x+14)(x-2)\implies x= \begin{cases} -14\\ \boxed{2} \end{cases}$

because B is on the IV Quadrant, the x-coordinate must be positive.

Alonzo invested his savings in two investment funds. The amount he invested in Fund A was $2000 less than the amount he invested

alina1380 [7]

Answer:

There were $13,200 in Fund B.

Step-by-step explanation:

We are given the following in the question:

Let x be the amount in Fund A and y be the amount in Fund B.

The amount he invested in Fund A was 2000$ less than the amount he invested in Fund B.

Thus, we can write the equation:

$x = y -2000$

Profit percent on Fund A = 7%

Profit percent on Fund B = 8%

Total profit = $1960

Thus, we can write the equation:

$7\%(x) + 8\%(y) = 1960\\7x + 8y = 196000$

Solving the two equations by substitution, we get,

$7(y-2000) + 8y = 196000\\\Rightarrow 15y = 198000\\\Rightarrow y = 13200\\\Rightarrow x = 11200$

Thus, there were $13,200 in Fund B.

During dance practice, Sasha drank 2 1/2 pints of water, and on the way home she drank 1/2 cup of water. How much did she drank

Anarel [89]

Answer: 5 cups 4 ounces

Step-by-step path to answer:

Pints to cups:

1 pint= 2 cups

2 pints= 4 cups

0.5 pints=1 cup

2.5 pints= 5 cups

Cups to ounces:

1 cup= 8 ounces

0.5(1/2) cups= 4 ounces

All together:

2.5pints + 0.5cups = 5cups 4ounces
