Mr. Greenjeans wants to make a triangle shaped garden. Two sides of the garden are 52 meters and 90 meters. The angle between these two sides is 102º. What is the area of the garden?
Answers
Answer:
[tex]Area = 2288.754m^2[/tex]
Step-by-step explanation:
The given parameters can be represented as:
[tex]A = 52m[/tex]
[tex]B=90m[/tex]
[tex]\theta = 102^{\circ}[/tex]
Required
Determine the area of the garden
Provided that [tex]\theta[/tex] is between A and B, the area is:
[tex]Area = \frac{1}{2}AB sin(\theta)[/tex]
Substitute values for A, B and [tex]\theta[/tex]
[tex]Area = \frac{1}{2}AB sin(\theta)[/tex]
[tex]Area = \frac{1}{2} * 52 * 90 * sin(102)[/tex]
[tex]Area = \frac{1}{2} * 52 * 90 * 0.9781[/tex]
[tex]Area = \frac{52 * 90 * 0.9781}{2}[/tex]
[tex]Area = \frac{4577.508}{2}[/tex]
[tex]Area = 2288.754[/tex]
Hence, the area of the garden is [tex]2288.754m^2[/tex]

Step-by-step explanation:

Two given angles cannot be both vertical and adjacent which is the correct answer would be option (D)
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.
When two angles are congruent, or equal in size, and they are immediately opposite one another, they are said to be vertical.
Vertical angles do not share a common side, but rather a common vertex or point.
A vertex and a common side are shared by adjacent angles.
Since vertical angles can not have a common side when they are immediately opposite one another, two given angles cannot be both vertical and adjacent.
Hence, the correct answer would be option (D)

Step-by-step explanation: This triangle does not form a right triangle because it does not have a 90 degree angle.
Answer:
No
Step-by-step explanation:
Use Pythagorean Theorem: (a^2 + b^2 = c^2)
a^2 + b^2
(14)^2 + (15)^2

What is the area of a circle is the radius is 8
Answers
Area of circle = pi x radius² (pi x 8²)
Step-by-step explanation: To find the area of the circle,
start with the formula for the area of a circle, which is [tex]A = \pi r^{2}[/tex].
Notice that our circle has a radius of 8 units.
So plugging into the formula, we have (π)(8 units)².
Now, (8 units)² is equal to 8 units × 8 units or 64 units².
So we have 64π units² which is an exact answer.

The solution to the equation [tex]3^s[/tex] = 27 is s = 3.
To solve the equation [tex]3^s[/tex] = 27, we need to find the value of s that makes the equation true.
Since 27 can be written as 3³ (3 raised to the power of 3), we can rewrite the equation as:
[tex]3^s[/tex]= 3³
To solve for s, we can equate the exponents:
s = 3
Therefore, the solution to the equation [tex]3^s[/tex] = 27 is s = 3.

A recipe calls for 3 cups of flour to make two batches of dinner rolls. One batch mix 15 rolls. Where is making dinner for 12 people and only needs one roll per person. What proportion will help Laura find how much flowers need to make 12 dinner rolls? A 3/30=x/12 B 3/2=x/12 C 3/15=x/12 D 12/15=x/3
Answers
Answer: A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]
Step-by-step explanation:
According to the recipe,
For 2 batches, 3 cups of flour required.
One batch has 15 mix rolls
Then 2 batches will have 2 (15) = 30 rolls
Each person gets one roll, so 3 cups of flour is required for 30 people.
The quanity of flour is proportional to the number of people.
Let x be the quantity of flour required for 12 people.
By proportion,
[tex]\dfrac{\text{Quantity of flour}}{\text{Quanity of person}}=\dfrac{3}{30}=\dfrac{x}{12}[/tex]
Required proportion: [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]
The correct option is A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Write and solve a system of linear equations that represent the situation. There are a total of 64 students in two clubs: xylophone and yo-yo. The xylophone club has 10 more members than the yo-yo club. How many members are in the xylophone club? How many members are in the yo-yo club?
Answers
Answer:
x + y = 64
x = 10 + y
Yo-yo = 27
Xylophone = 37
Step-by-step explanation:
Let :
Xylophone club = x
Yo - Yo club = y
Total members = 64
Xylophone club has 10 more members than yoyo
Hence,
x + y = 64 - - (1)
x = 10 + y - - (2)
Put x = 10 + y in (1)
10 + y + y = 64
10 + 2y = 64
2y = 64 - 10
2y = 54
y = 54 / 2
y = 27
From (1)
x + 27 = 64
x = 64 - 27
x = 37

You calculate speed, by dividing distance by time.
So 18 divided by 24 is 0.75. That is Ciera's speed.
And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667
