Answer:
Find out how much is 1
Multiply 1/2 by 2 to get 1 and multiply 14 by 2 so the ratio is equal
1/2 x 2 = 1
14 x 2 = 28
so 1 = 28
Multiply everything 28
I'm pretty sure I have it in order clockwise
3/14 x 28 = 84/14 = 6/1 = 6
1/14 x 28 = 28/14 or 2
5/7 x 28 140/7 = 20
3/7 x 28 = 84/7 = 12
2/7 x 28 = 56/7 = 8
1/7 x 28 = 28/7 = 4
3/4 x 28 = 84/4 = 21
1/4 x 28 = 28/4 = 7
I'm guessing the middle would be 1 is 28
Hope this helps

Solve the right triangle, ΔABC, for the missing side and angles to the nearest tenth given sides a = 13.2 and b = 17.7.
Answer:
Side c = 22.1
Angle A = 36.7°
Angle B = 53.2°
Angle C = 90.1°
Step-by-step explanation:
Triangle ABC is a right angle
Where given sides
a = 13.2
b = 17.7
We can find c using Pythagoras Theorem
Pythagoras Theorem for a right angle triangle=
c² = a² + b²
c = √(a² + b²)
c = √(13.2² + 17.7²)
c = 22.08008
≈To the nearest tenth = 22.1
We can solve for Angles A, B, C using Cosine rule
Angle A
a² = b² + c² - 2bc × Cos A
Cos A = b² + c² - a²/2bc
A = Arc cos ( b² + c² - a²/2bc)
A = Arc cos ( 17.7² + 22.1² - 13.2²/2 × 17.7 × 22.1)
A = 36.67563°
≈ To the nearest tenth = 36.7°
Angle B
b² = a² + c² - 2ac × Cos B
Cos B = a² + c² - b²/2ac
B = Arc cos (a² + c² - b²/2ac)
B = Arc cos(13.2² + 22.1² - 17.7²/ 2 × 13.2 ×22.1)
B = 53.21647°
≈Approximately to the nearest tenth = 53.2°
Angle C
c² = a² + b² - 2ab × Cos C
Cos C = a² + b² - c²/2ab
C = Arc cos ( a² + b² - c²/2ab)
C = Arc cos ( 13.2² + 17.7² - 22.1²/2 × 13.2 × 17.7)
C = 90.1079°
≈ to the nearest tenth = 90.1°
A farmer wants to estimate the number of rabbits on his farm.

Answer: 560 total rabbits
Step-by-step explanation:
Your assumptions are great but you can also add the assumption that the ratio of the rabbits caught on Monday is the same ratio of the rabbits caught on Tuesday.
[tex]\text{Tuesday:}\quad \dfrac{15\ tags}{70\ rabbits}=\dfrac{3\ tags}{14\ rabbits}\ \leftarrow simplified[/tex]
Assumption:
3/14 of the total rabbits on the farm = 120 tagged on Monday
Let r represent the total rabbits on the farm
then (3/14)r = 120
r = 120(14/3)
r = 560

distribute
(x+15) + 3x+45+x
remove parenthesis
x + 15 + 3x + 45 + x
Add like terms
5x + 60 = 245
Subtract 60 from both sides
5x + 60 - 60 = 245 - 60
5x = 185
divide by 5

Which function is represented by this graph?
Answer:
Option B.
Step-by-step explanation:
From the given graph it is clear that it is a V-shaped graph. It means, it is the graph of absolute function.
The vertex form of an absolute function is
[tex]y=a|x-h|+k[/tex]
where, a is a constant and (h,k) is the vertex.
From the given graph it is clear that the vertex is at (7,-3). It means h=7 and k=-3.
[tex]y=a|x-(7)|+(-3)[/tex]
[tex]y=a|x-7|-3[/tex] ...(1)
It passes through (4,0).
[tex]0=a|4-7|-3[/tex]
[tex]3=3a[/tex]
[tex]1=a[/tex]
Put this in (1).
[tex]y=1|x-7|-3[/tex]
[tex]y=|x-7|-3[/tex]
Therefore, the correct option is B.
What is the product of (-a + 3)(a + 4)?
Answer:
-a^2 -a + 12
Step-by-step explanation:
You have to multiply all four together.
-a times a = -a^2
-a times 4 = -4a
3 times a = 3a
3 times 4 = 12
Add them all together =
-a^2 - a + 12
The answer is :
-a^2-a+12
Step-by-step explanation:
-a(a) is -a
-a(4) is -4a
3(a) is 3a
3(4) is 12
So,
-a^2-4a+3a+12
Simplify
-4a+3a is -a bcz -4+3 is -1
Final answer
a^2-a+12

Manatee Springs
Elephant
House
3,500 yds
- 200 yds
Tran Depot
2000
Bird Sanctuary
Main Gate
(SHOW WORK)
Answer:
6.04 km
Step-by-step explanation:
From the image attached, both triangles form are similar to each other because their corresponding angles are equal, therefore they are equiangular triangles. equiangular triangles have the same shape but different sizes and the ratio of their corresponding sides are equal.
Therefore since their corresponding sides are equal we can calculate the distance from the main gate to Manatee Springs. It is given by:
[tex]\frac{3500\ yards}{2000\ yards} = \frac{4200\ yards}{x}\\ x= \frac{4200\ yard*2000\ yards}{3500\ yards}=2400\ yards[/tex]
x = 2400 yards.
The distance from the main gate to Manatee Springs = x + 4200 yards = 2400 + 4200 = 6600 yards
The distance from the main gate to Manatee Springs = 6600 yards = (6600 * 0.0009144) km = 6.04 km
The distance from the main gate to Manatee Springs = 6.04 km

Trig work i don’t understand. pls help
Answer: A
Step-by-step explanation:
So we know that to find the area of a triangle you have to multiply the base times the height and divide it by two or multiply it by 1/2.Looking the information given it say that theta is equal to 26 degrees and the length of a or the hypotenuse is 25 and b which in this case is the base is 32. So the information gives us the base but now we need to find the height.
To find H we need to apply trigonometry solve for h the height.
As we could see theta which is 26 degrees is opposite the height and we know the hypotenuse length. So using soh cah toh we have to know that the length of h is going to be using the sin formula opposite over hypotenuse.
[tex]sin(26)=\frac{h}{25}[/tex] solve for h by multiplying both sides by 25.
h= 25 sin(26)
h= 10.96 is being rounded to the nearest hundredth because that is essential
Now we know H is equal to 10.96 which is the Height so now we have all the information we need the height and the base.
Multiply 10.96 by 32 and divide it by 2.
10.96 * 32 = 350.72
350.72 /2 = 176.36
The best answer is A because that is the only best approximation to 175.35.

Answer:
Option (C). 4.6 cm
Step-by-step explanation:
In the figure attached,
A right triangle has been given with hypotenuse = 6 cm, leg 1 = x cm, leg 2 = y cm and one angle = 50°
By applying Sine rule in this triangle,
Sin(50)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}=\frac{\text{Leg 1}}{\text{Hypotenuse}}[/tex]
Sin(50)° = [tex]\frac{x}{6}[/tex]
x = 6(Sin50°)
x = 4.59
x ≈ 4.6 cm
Therefore, Option (C) will be the answer.
