Answer:

25

Step-by-step explanation:

(-5)^2 = 25, since -5 x -5 is 25.

Now, if the -5 hadn't been in parenthesis, -5^2 would be read as -(5 x 5), and would equal -25.

The annount of time (in minutes) that it takes to put out a fire varies inversely
sveticcg [70]

Given that the amount of time varies inversely with G.

It can be written as,

T G=K

where K is the constant.

We need to determine the time it takes to put out the fire when 200 gallons of water are used.

<u>The value of constant:</u>

When G=8, T=12 , we get;

(12)(8)=K

      96=K

Thus, the value of constant is  96.

<u>Time taken:</u>

Substituting G=2 and K=96 in the formula T G=K, we get;

T(2)=96

    T=48

Thus, the time taken to put out the fire using 200 gallons of water is 48 minutes.

Hence, Option B is the correct answer.

6x + 5y = 4<br> - 6x + y = 20
Masja [62]

Answer:

x = -8/3

y = 4

Step-by-step explanation:

I assume you want to solve for x and y.

The best way to do this with the two formulas given is elimination. This means add the two equations together.

6x + 5y = 4

-6x + y = 20

The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with

6y = 24

Now solve for y by dividing both sides by the 6.

y = 24/6 = 4

Now that we have y, you can plug it into one of the equations and solve for x.

Let's use -6x + y =20.

So plug in the 4 for y to get -6x + 4 = 20

Subtract the 4 from both sides then solve for y by dividing both sides by the -6.

-6x = 16

x = -16/6

You can reduce that down so that x = -8/3.

The hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

14^2=9^2+c^2.

c^2=196-81.

c^2=115.

c=√115.

c=10.72~11cm
