Finger [1]

Answer:

Step-by-step explanation:

Given

Badwater = -282ft

Telescope\ Peak = 11043ft

The position of badwater is negated because it is below sea level

The interpretation of the question, is to calculate the distance between the two given points.

This is calculated as:

Difference = Telescope\ Peak - Badwater

Difference = 11043ft - (-282ft)

Open bracket

Difference = 11043ft+282ft

Difference = 11325ft

<em>Hence, the distance between both is 11325ft</em>

Kipish [7]

Answer:

8% increase

Step-by-step explanation:

In this question, we are asked to calculate the percentage increase that a certain increment will give over a period of 10 years.

Let the increment be x

Mathematically from the question, we can obtain that ;

(1+x)^10 = (1+1.2)

(1+x)^10 = 2.2

1+ x = 2.2^1/10

1+x = 1.082

x = 1.082 - 1

x = 0.082

This means that x = 8.2% which is approximately 8%

How many degrees is angle x
agasfer [191]

Answer:

The degrees of angle x is 180 degrees.

Step-by-step explanation:

Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of x.

Simplify 36x^4 42x^7
Alja [10]
The first step to simplify this equation is to multiply the numbers
1512x^{4}×x^{7}
next,, youll multiply the terms with the same base by adding their exponents
1512x^{4+7}
finally,, youll add the numbers together
1512x^{11}
since you cant simplify any further,, the correct answer to your question is 1512x^{11}
