Answer:
Step-by-step explanation:
Let the numbers are 2x and 2x + 2.
<u>We have:</u>
- (2x + 2x + 2)² = (2x)² + (2x + 2)² + 48
- 4(2x + 1)² = 4x² + 4(x + 1)² + 48
- (2x + 1)² = x² + (x + 1)² + 12
- 4x² + 4x + 1 = x² + x² + 2x + 1 + 12
- 2x² + 2x - 12 = 0
- x² + x - 6 = 0
- (x - 2)(x + 3) = 0
- x = 2, x = -3
<u>The numbers are:</u>
This problem can be solved via a simple ratio and proportion approach. The concept is, the ratio of the actual length to the model length is constant. The solution is as follows:
Actual/Model = 12 m/ 1 cm = x/7.25 cm
Solve for x,
x = 87 m
<em>So, the actual distance is 87 m.</em>
we know that
m∠ZWY=m∠WXY --------> given problem
so
In the right triangle ZWY
In the right triangle XWY
<u>Find the value of b</u>
<u>Applying the Pythagorean Theorem</u>
In the right triangle XWY
therefore
<u>the answer is the option</u>
D) 9.4 units
Answer:
first you need to figure out how much is in a roll and then divide the answer you got for the first one by that number and then that should be your answer for ii, if I'm not mistaking.
