If you flip the 30-60-90 triangles so they look similar, and find the difference between the length of 60, and the length of 40.
40÷60 =.6666 etc
You can prove this by plugging in
60 •.66666 = 39.9999 or about 40.
The triangle I started with had a length of 60, so just used the tangent of 60° to find the adjacent.
Since we know the relationship of the triangles,
Multiply your answer, 103.923 •.666666
Which equals 69.2819
69.2819 is the length of the 40 triangle.
Add them together, and you get 173.2049.
Or 173.20 m
Answer: 0.95 x 10^2
Explanation:
2.85 x 10^6/30,000
= 2.85 x 10^6/3 x 10^4
= 2.85 x 10^2/3
= 0.95 x 10^2
1) When you have an exponent being raised to an exponent, you multiply them. 2*3 is 6, so you have x^6, which would make C your answer.
2) You reduce them by subtracting the top ones from the bottom ones, so it becomes x^2*z. The y's cancel out, 6-4 is 2 and 9-8 is 1. Your answer is C again.
3) As you did in one, simply multiply out the top first. The top them becomes 9x^12*y^18. Subtract the bottom exponents to get 9x^6y^9/3, which then becomes 3x^6*y^9, which is D.
4) When you have a square root over a square root, you can put the numbers inside like this: . 81 over 27 is equal to 3, so you have sqrt3 as your answer - A.
5) You have sqrt2*2*sqrt3. You can put 2*3 under the square root together, and they multiply to 6, so you have 2sqrt6 - D.
Answer:
Place value is defined as the digit multiplied wherever it is placed, either by hundreds or thousands. Face value is simply defined as the digit itself within a number. Place value of a digit should be multiplied by the digit value of the position where it is located.
