To solve this problem you must apply the proccedure shown below:
1. Let's call: the number of roses and the number of lilies.
2. You must make a system of equation based on the information given in the problem above:
3. Use the method of substitution. First, solve for in the second equation, then substitute it into the first equation, and then solve for :
4. Now, substitute into the second equation:
Therefore, the answer is: roses and lilies.
We develop two equations based on the given diagram. We let x be the length from C to the point meeting the endpoint of 5. We let y be the length of CD.
First, we determine the length from D to the endpoint of line measuring 9 cm. We use the Pythagorean theorem.
l = sqrt ((3)² + 5²)
l = 5.83
Then, the equations that can be developed or established are:
x² + 6² = y²
9² + (5 + x)² = (y + 5.83)²
In solving for x and y, we use substitution.
From the first equation,
y = sqrt (x² + 36)
We substitute this to the second equation y.
The value of x is 9.51.
y = sqrt (9.51² + 36) = 11.25.
Calculate for the area of the bigger triangle.
A = 0.5(9 cm)(5 + 9.51 cm) = 65.295 cm²
Also calculate for the area of the smaller triangle,
A = (0.5)(6 cm)(9.51 cm) = 28.53 cm²
The difference between the areas is 36.765 cm².
<em>ANSWER: 36.77 cm²</em>
Boiii. Job. Look. Jkjk. Bbh. Bbhhh yes I did
but yuyyyyyyyy
Does it say what the diameter or the radius is??
Answer:
length: 30 ft
width: 15 ft
Step-by-step explanation:
The sum of length and width is half the perimeter, 45 ft.
The ratio of length to width is 2 : 1, so the sum in "ratio units" is 2+1 = 3. That is, each "ratio unit" stands for 45 ft/3 = 15 ft of actual length.
Jason's pool is ...
length : width = 2·15 ft : 1·15 ft = 30 ft : 15 ft
Jason's pool is 30 ft long and 15 ft wide.
