10. What is the distance between (8,7) and (3,-5)?
Anarel [89]

Answer:

distance between points=13 units

Step-by-step explanation:

distance between points=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

put (x_1,x_2)=(8,7) and (y_1,y_2)=(3,-5)

distance between points=\sqrt{(3-8)^2+(-5-7)^2}

distance between points=\sqrt{(-5)^2+(-12)^2}

distance between points=\sqrt{25+144}

distance between points=\sqrt{169}

distance between points=13 units answer

Water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. Which would not be a proportion you could use to solv
enot [183]

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

First, we need to convert 2 2/3 hours to minutes. This would be:

= 2 2/3 × 60 minutes

= 8/3 × 60 minutes

= 160 minutes

Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:

= (162 1/2 × 2 2/3hours) / 15 minutes

= (162 1/2 × 160) / 15

= 1733 1/3 gallon

A family of 3 shares the minutes on a cell phone plan. Suppose the plan allows for 675 minutes per month. How many minuets are l
Olegator [25]
Let's come up with variables to substitute and make an equation.

T = total number of minutes
P = number of minutes used by each person in the phone plan
R = remaining minutes per month

R=T-3P

Now that we have an equation, we can substitute the numbers we are given in the problem to find the final solution.

R= 675- 3(250)
R= 675- 750
R= -75 minutes

There are no remaining minutes, and in fact, the people on the phone plan have used 75 extra minutes than provided for in their phone plan.
