Solve for v 209=40-v

Mathematics
1 answer:
andrew-mc [135]3 years ago
6 0

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.

Please please help me.I am so lost with this math
Arte-miy333 [17]

Answer:

6\sqrt{5}

Step-by-step explanation:

In any right triangle, the Pythagorean theorem states:

a^2+b^2=c^2, where a and b are two legs of the triangle and c is the hypotenuse.

Plugging in given values, we have:

12^2+VU^2=18^2,\\144+VU^2=324,\\VU^2=180,VU=\sqrt{180}=\sqrt{36}\cdot \sqrt{5}=\boxed{6\sqrt{5}}

Activity: A flagpole has cracked 1.7 m from the ground and fallen over, as if hinged. The top of the flagpole hit the ground 3 m
Anastasy [175]

Answer:

Height of flagpole before it fell = 5.15 m

Step-by-step explanation:

Given:

Height of remain pole (p) = 1.7 m

Distance from base (b) = 3 m

Find:

Height of flagpole before it fell

Computation:

Using Pythagorean theorem

H = √ p² + b

Length of broken part = √ 1.7² + 3²

Length of broken part = √ 2.89 + 9

Length of broken part = √ 11.89

Length of broken part = 3.45 (Approx)

Height of flagpole before it fell = Length of broken part + Height of remain pole

Height of flagpole before it fell = 3.45 + 1.7

Height of flagpole before it fell = 5.15 m

Find the slant height of a square pyramid with base edges of 12 cm and an altitude of 8 cm?
liberstina [14]
To find the slant height we must take apart the pyramid first. Let us cut it in half. There we can easily see that the slant height is really just the hypotenuse of the triangle formed by half the base and the altitude.

Half the base length would be 6 cm.

Using the Pythagorean therom:

a² + b² = c²
6² + 8² = c²
36 + 64 = c²
100 = c²
c = 10

The slant height should be 10 cm. Hope this helps!
