Hello there!

One way that I would do is make this triangle flat, if you can picture. that. We know that AC = 7 and BC = 8.

8 squared would be 64, and 7 squared would be 49.

Therefore, 64 = 49 + AB^2

AB = 15 squared.

Your answer: 15√

A leaking pond looses 18 gallons of water in 34 hours , how many gallons will be left after 41 hours
Ann [662]

The amount of water left = 21.3 gallons.

We have a leaking pond which looses 18 gallons of water in 34 hour.

We have to determine how many gallons of water will be left after 41 hours.

<h3>What do you understand by gallon?</h3>

The gallon is a unit of volume in imperial units and United States customary units.

I gallon = 231 cubic inches = 3.785411784 liters.

According to question, we have -

Amount of water lost by the pond in 34 hours = 18 gallons

Therefore -

Amount of water lost by the pond in 1 hour = \frac{18}{34}

So, the amount of water loosed by the pond in 41 hours = \frac{18}{34}\times 41  = 21.3

Hence, the amount of water left = 21.3 gallons.

Write an equation of the line in slope-intercept form that is parallel to the line y= -4 + 2 and passes through (2,4)
garik1379 [7]

Answer:

Step-by-step explanation:

If the lines are parallel, it means that the slopes are the same.  To write an equation in the slope intercept form, we need the slope and the y-intercept.  We are given the slope.  We need to find the y-intercept.  We can use the slope and the point to help us.  The point is written in the form (x,y).  In this case the point is (2,4) so we will use 2 for x and 4 for y.

y = mx + b  Plug in what we know

4 = -4(2) + b  b is what we are looking for.  It is the y-intercept

4 = -8 + b  Now add 8 to both sides

12 = b

Now we can write the equation:

y = -4x +12
