Answer:

22.7604763 degrees

Step-by-step explanation:

Note that the answer is NOT 20 degrees.

She adjusted the ramp to half the original incline

Therefore we have tan 40 = x = 0.839099631.

We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815

Taking the arctan of both sides, we get

y = arctan(0.419549815) = 22.7604763 degrees

Zero

Zero is just a number 0. It is between the negative and positive. 0 is neither positive or negative but it is categorized as Zero.

Negative Integers

Negative Integers are opposite of Positive Integers. The opposite of plus is minus and the opposite of minus is plus. Negative Integers are less than both 0 and Positive Integers. Here is the example: -1,-2,-3,-4,-5,...

Answer:

Step-by-step explanation:

Remark

The last digit is 1 3 5 7 9 because the last digit is odd.

The first digit must be a 3 because the number is between 300 and 350

Let the first digit = x

Let the second digit = y

Let the third digit = z

x + y = z

x + y + z = 14 Substitute z for x + y

z + z = 14 Combine

2z = 14 Divide by 2

2z/2 = 14/2

z = 7

The first digit is 3 and the third digit = 7

The middle digit is 3 less than the last digit.

y = 7 - 3 = 4
