Answer:

9sqrd= 81

12sprd= 144

144+81= 225

\sqrt{225}= 15

so c=15

ps. use Pythagoras to help you.

Answer:

c=15

Step-by-step explanation:

You can use Pythagoras theorem to find the value of c

Formula to find the hypotenuse:

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

The value of a in the formula will be the height & the value for b in the formula is the base.

Now, add the values in the formula:

c=\sqrt{9^{2}+12^{2}  }

c=\sqrt{81+144 }

c=\sqrt{225}

c=15.96871942

You can simply say that:

c=15

I hope this helps :)

Solve for v 209=40-v
andrew-mc [135]

Answer:

-169

Step-by-step explanation:

We want to isolate v.

Method 1:  subtract 40 from both sides, obtaining  169 = -v.  Then change the sign of both sides, arriving at v = -169.

Method 2:  Add v to both sides.  Then v + 209 = 40.

Now subtract 209 from both sides, obtaining -169.

A boat traveled 37 miles in 2 hours. At this<br> rate, how many miles will the boat travel in
Inessa [10]

<u><em>Answer:</em></u>

i. The boat will travel 18.5 miles in one hour

ii. The boat will travel 9.25 miles in half an hour

iii. The boat will travel 27.75 miles in one and a half hours

<u><em>Explanation:</em></u>

We are given that the boat travel 37 miles in 2 hours

To get the miles traveled, we can simply use cross multiplication

<u>i. Miles traveled by the boat in one hour:</u>

37 miles .....................> 2 hours

x miles ........................> 1 hour

x = \frac{37*1}{2}=18.5 miles

<u>ii. Miles traveled in half an hour:</u>

37 miles .....................> 2 hours

x miles ........................> 0.5 hour

x = \frac{37*0.5}{2}=9.25 miles

<u>iii. Miles traveled in an hour and a half:</u>

37 miles .....................> 2 hours

x miles ........................> 1.5 hour

x = \frac{37*1.5}{2}=27.75 miles

Hope this helps :)

Given that two sides of a triangle have sides 5 and 7, write the range of the lengths of the third side:
matrenka [14]

Answer:

Step-by-step explanation:

The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.

So the maximum value must be less than 12. What's the smallest x could be?

well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?

5 + y > 7

5 - 5 + y > 7 - 5

y > 2

So the range    is  2 < x < 12

How else could you write this?

2 < x

x < 12 is one way.
