A2 + b2 = c2 If a = 12 and c = 15, find the value of b using the Pythagorean theorem. b = 399 b = 19.97 b = 81 b = 9

1 answer:

3 0

The answer and value of b would be <u>9</u>. Square the value of c (15, its square is 225), then subtract that by the square of 12 (144) to get 81. Square root 81 to get 9.

Hope this helps! If it did, would you mind marking this answer as Brainliest? Thanks :D

Answer: 13.5 Okay! Here's the method count the legs of the right triangle

The formula we'll use will be

A^2 + B^2 = C^2

In this case we're counting by twos

The base is 11 so we times it by itself =110

The leg is 8.5 so we going to times itself to make 72.25 add those together so 110+ 72.25 = 182.25 then we \|-----

182.25

Then you have got ur answer of 13.5

Solve this equation for x. round your answer to the nearest 0 = ln (x+6)

MissTica

Answer: $x=-5$

Step-by-step explanation:

To solve this exercise you need to remember the following:

$e^{lnx}=e^{lny}$ → $x=y$

Therefore, keeping the above on mind, you can solve for x as following:

$e^0=e^{ln(x+6)}$

$e^0=x+6$

Remember that, by definition: $a^0=1$ , then you have:

$1=x+6$

Subtract 6 from both sides of the equation.

Then the value of x is:

$1-6=x+6-6\\x=-5$

A blueprint for a house has a scale of 1:5 feet. The living room has a length of 2.5 inches and a width of 3 inches. What is the

stiks02 [169]

Answer:

Step-by-step explanation:

Set this up as a proportion, with inches on the top and feet on the bottom for our scale. We will find the actual length first, then we'll find the width.

$\frac{in}{ft}:\frac{1}{5}=\frac{2.5}{x}$

Cross multiply to get that the actual length is 5(2.5) = 12.5 feet. Now for the width:

$\frac{in}{ft}:\frac{1}{5}=\frac{3}{x}$

Cross multiply to get that the actual width is 5(3) = 15 feet.

If you want the area of the room, multiply the length times the width to get

A = 15(12.5)

A = 187.5 feet squared
