Answer:
In y = kx, where k is the constant of proportionality.
A right triangle ABC is formed when we join three points around a lake. Length of the side AC = 6 miles. Length of the side BC = 2 miles. We have to find Length of side AB.Using Pythagorean theorem for Right triangle ABC , Right angled at B→AB² + BC²= AC²→ AB² + 2²= 6²→ AB² = 36 - 4→ AB²= 32→ AB = √ 32→→AB = 5.66 (approx)Option (B) AB = 5.66 is Right choice.
To get a percentage, you need to first round the decimal to the hundreths place. Whenever you have a number greater than 5, you round up.
Therefore, you can round it to 0.78.
Now to get the percentage you multiply it by 100.
This shows your answer is
(c) 78%.
Answer:
b. none
Step-by-step explanation:
An angle has internal angles adding to 180º.
Those angles only add to 170º so no triangle can be made.
To find the answer all you do is switch the percentage to a decimal and multiply by the number you were given. For example on 1a, 19% as a decimal is 0.19 and 0.19 * 360 is 68.4. All of 1 and 2 questions work this way. For number three, take the fraction and convert it to a decimal (so 1/2 will be 0.5, 1/3 will be 0.33, etc) and add that to the whole number. For example, 3a would be 33.33%. 3b would be 12.5%.
Hope this helps!
