With these questions, the best approach is to draw a diagram to represent the question. Draw a right angle triangle with an angle of elevation 29 degrees (make sure to label the angle that meets the base and hypotenuse as 29 degrees).
From here, we say that the hypotenuse is the slide itself, which is 5.4 metres. Using basic trigonometric ratios, we can deduce that:
sin(29) = x/5.4
x = 5.4sin(29) which is approximately 2.62 metres.
Answer:
x = -7
Step-by-step explanation:
This is a multi-step equation in algebra. We are expected to isolate the given variable and find the constant value that it is equal to. In order to do this, we can follow some steps:
1x - 15 = 5x + 13 Subtract 5x on both sides of the equation.
-4x - 15 = 13 Add 15 to both sides of the equation.
-4x = 28 Divide by -4 on both sides of the equation.
x = -7
You can input this value and make sure that the answer is correct.
1(-7) - 15 = 5(-7) + 13
-7 - 15 = -35 + 13
-22 = -22
-22 equals -22, so x = -7 is the solution to the equation.

Steps
find the Least Common Multiple of the denominators (which is called the Least Common Denominator).
Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator.
Then add (or subtract) the fractions, as we wish!
your denominators stay the same so its 20
Answer:
- C. neither. the roof and walls are the same shade of green
Step-by-step explanation:
<u>The first batch:</u>
- Some white and some green
<u>The second batch:</u>
- Triple amount of white and triple amount of green
As we see the ratio of white to green has not changed
Therefore there won't be any difference in painting
Correct answer choice is C.
