Answer:

7.4

Step-by-step explanation:

Pythagorean theorem is a^{2} +b^{2} =c^{2} with c being the hypotenuse and a and b being the legs.

So we are solving for a leg so let's rearrange the equation to solve for a or b, it doesn't matter, I'm going to solve for a.

so subtract b^{2} from both sides then take the square root of both sides leaving us with a=\sqrt{c^{2} -b^{2} }

Then plug in know variables so a=\sqrt{8^{2} -3^{2} } =\sqrt{64-9} =\sqrt{55} =7.41619848

Then round to get 7.4

<u>Answer:</u>

  • a = 7.4

<u>Step-by-step explanation:</u>

<u>We can find 'a' through Pythagoras theorem.</u>

  • => 8² = 3² + a²
  • => 64 = 9 + a²
  • => a² = 55
  • => a = √55
  • => a = 7.416 = 7.4

Hoped this helped.

A gas can hold 10 L of gas. How many cans could we fill with 7 L of gas?
katrin2010 [14]

Answer: It is only one can that can be filled up.

Step-by-step explanation: If 1 gas can can hold 10 L of gas and you only have 7 L then how can you fill up more than 1 gas can with only 7 L?  You don't have enough gas to fill up more than 1 gas can. So you are left with only 1 gas can filled but only with 7 L.

How many solutions does the following equation have?
RoseWind [281]

Answer:

There will be No solution for the equation 9x - 4 = - 3x + 5 + 12x. Option B is correct.

Step-by-step explanation:

We need to determine how many solutions the equation 9x - 4 = - 3x + 5 + 12x have.

Solving the equation and finding the solutions

9x - 4 = - 3x + 5 + 12x

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

9x +3x-12x =  5 + 4

Simplifying

12x-12x =  9\\0=9

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation 9x - 4 = - 3x + 5 + 12x. Option B is correct.
