Answer:

Step-by-step explanation:

What we have to know is that when two triangles are similar their sides will always be proportional. So we will create a proportion that goes like this... $\frac{\Delta1side}{\Delta1base} =\frac{\Delta2side}{\Delta2base}$ but since it doesn't tell us the exact value of triangle 1. We will have to add 3 and 12 to get 15 which is the base of the first triangle. Now we're ready to write the proportion.

$\frac{4x}{15}=\frac{3x+1}{12}$

Now we cross multiply and solve the equation...

$48x=15(3x+1)\\48x=45x+15\\3x=15\\x=5$

So the value of x is 5.

A mountain climber ascends 800 feet per hour from his original position. After 6 hours, his final position is 11,600 feet above

coldgirl [10]

To find the beginning position, we need to know how many feet the climber has ascended in the 6-hour time frame. At the rate of 800 feet per hour, this would total to 4,800 feet in 6 hours (800 * 6). Subtracting this amount from the final position would give the elevation at the beginning of the ascent: (11600 - 4800) = 6,800 feet above sea level to begin.

Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .

Triangle:

A = 3 x 9 x 1/2 = 13.5

Large rectangle (center):

A = 9 x 12 = 108

Medium rectangle:

A = 4 x 6 = 24

Small rectangle (bottom):

A = 4 x 2 = 8

Figure:

A = 13.5 + 108 + 24 + 8 = 153.5 square feet

Hope this helps! :)

If x equals a real number, x^0 equals what?

Stels [109]

Hey there!

$x^0$

Anything to the power of 0 is 1. So that means x can be equal to any number. Let's say 1^0, it will still equal 1. 2^0 is also equal to 1. X is therefore not a number since it can be anything.

$x^0=1$
