Answer:

6) 6\sqrt{2}

9) 40

10) \frac{5\sqrt{2} }{2}

11) 13

Step-by-step explanation:

6)A right triangle rule: if 2 legs are equal, the hypotenuse is the length of that leg*\sqrt{2}

9) Pythagorean Theorem

a^{2} +b^{2} =c^{2}

We know the hypotenuse (41) so we substitute that for c and 9 for b now we need to find a

\sqrt{41^{2}-9^{2}  } which gives us 40

10) same with #6 but we do the opposite. SInce we have the hypotenuse, we can divide that by \sqrt{2} because we know that if 2 legs are equal, the hypotenuse is multiplied by \sqrt{2}. Multiply the numerator and denominator by \sqrt{2} because we can't have a square root in the denominator.

11) like #9 we have the a and b but we need to find c

a=5 b=12 c=r

so \sqrt{5^{2}+12^{2}  } which gives us 13

Hello,

Your answer would be:

2=2

Your explanation/work would be:

7(2) - 12 = 8(2) - 14
14 - 12 = 16 - 14
2 = 2

John is a quarterback. This year, he completed 350 passes, which is 70% of all the passes he's attempted this
diamong [38]

Answer:

455 passes

Step-by-step explanation:

If 350 is only 70% of his passes, take the remaining percentage which is 30% and multiply it to the known value of completed passes which is 350. So 350x.30= 105. Then just add 105 to 350 and you get the total number of passes. Hope this helped!

Which step brings you closest to getting the variable alone on one side of the equation
Oliga [24]

Answer:

Adding 5 from both sides then dividing by 7

Step-by-step explanation:

The best way to isolate x is to add 5 to both sides first:

21 = 7x

Then to isolate x by itself divide both sides by 7

x = 3

That would be the value of x and your final answer.
