Answer:
The answer is B.
Step-by-step explanation:
The formula is Area = L x H
And remember perimiter is adding the legnth of all sides.
For A:
12 × 3 = 36
12 + 12 + 3 + 3 = 30
For B:
4 × 8 = 32
4 + 4 + 8 + 8 = 24
For C:
6 × 6 = 36
6 + 6 + 6 + 6 = 24
Hence, the answer is B, since B is the only one which meets the criteria.

Step-by-step explanation:
we know that the 3 sides add up to the perimeter of 18cm. We can use this to find the length of the 3rd side, CA.
AB + BC + CA = 18
7 + 3 + CA = 18
10 + CA = 18
CA = 8
The pythagorean theorem states that in a right triangle a2 + b2 = c2, where c is the length of the hypotenuse (the longest side opposite to the right angle) and a and b are the lengths of the other two sides.
In this problem we can replace a with 7, the length of AB, b with 3, the length of BC, and c with 8, the length of CA.
a2 + b2 = c2
72 + 32 = 82
49 + 9 = 64
58 = 64
Since the equation is not true, we can deduce that ABC is NOT a right triangle start, we know that the 3 sides add up to the perimeter of 18cm. We can use this to find the length of the 3rd side, CA.
AB + BC + CA = 18
7 + 3 + CA = 18
10 + CA = 18
CA = 8

a2 + b2 = c2
72 + 32 = 82
49 + 9 = 64
58 = 64

58 = 64
Since the equation is not true, we can deduce that ABC is NOT a right triangle
Answer:
ABC is not a right triangle.
Step-by-step explanation:
The perimeter of a triangle is the sum of all its sides(easier to see if you draw it):
P = AB + BC + AC
We can substitute the values we have:
18 = 7 + 3 + AC
18 = 10 + AC
AC = 8
In a right triangle, the hypotenuse is always the largest side and is equal to the square root of the squares of the legs by the pythagorean theorem(a^2 + b^2 = c^2). Our largest side is 8, so we would set that as equal to the hypotenuse:
8^2 = 7^2 + 3^2
64 = 49 + 9
64 = 58
64 is not equal to 58, so triangle ABC is not a right triangle.

Let A and B be two disjoint events such that P(A) = .30 and P(B) = .60. What is P(A and B)? 0.18 0.72 0.90 0 none of the above
Answer:
0
Step-by-step explanation:
If two events are disjoing (aka mutually exclusive) that means that there is 0 overlap or the intersection equals 0
So the probability of A and B occuring is 0 (because P(A∩B)= 0)
Shelby is in a hot air balloon where the balloon is shaped like a sphere with a diameter of 50 ft find the amount of space occupied by the balloon use 3.14 for pie and round your answer to the nearest tenth
Answer:
50ft x 3.14 = 157ft
Step-by-step explanation:
It's asking for the circumference.
circumference formula: [tex]C = 2\pi r[/tex]
To give you a better idea of the concept:
To make it simple, in a circle, there is the radius, diameter, and then the circumference.
Radius: The distance half way across the circle (see attachment below).
Diameter: The distance across the circle (see attachment below).
Circumference: The distance around the circle (see attachment below).
As you see, the radius is only half way across, so 2 times the radius would give us the full distance across (diameter).
(But this doesn't matter for this question because it already gave you the diameter (50ft), this was only so I could maybe help you understand the concept a bit more).
Your question:
Alright, it's asking for the circumference; all you have to do is the diameter (50 ft) times pi (3.14).
[tex]50ft *3.14=157ft[/tex]

Help with this please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
m∡A = 41.4°
m∡B = 48.6°
m∡C = 90°
a = 3[tex]\sqrt{7}[/tex]
b = 9
c = 12
Step-by-step explanation:
to find the length of side 'a' I used the Pythagorean Theorem to get:
a² + 9² = 12²
a² + 81 = 144
a² = 63
a = [tex]\sqrt{63}[/tex] which equals [tex]\sqrt{9}[/tex][tex]\sqrt{7}[/tex] which is 3[tex]\sqrt{7}[/tex]
to find m∡B I found the arcsin(B) = 9/12 to get 48.6
to find m∡A I subtracted the sum of 90 + 48.6 from 180°

Given:
The function is:
[tex]f(x)=6x-3[/tex]
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
[tex]f(x)=6x-3[/tex]
Step 1: Substitute [tex]f(x)=y[/tex].
[tex]y=6x-3[/tex]
Step 2: Interchange x and y.
[tex]x=6y-3[/tex]
Step 3: Isolate variable y.
[tex]x+3=6y[/tex]
[tex]\dfrac{x+3}{6}=y[/tex]
Step 4: Substitute [tex]y=g(x)[/tex].
[tex]\dfrac{x+3}{6}=g(x)[/tex]
Therefore, the inverse of the given function is [tex]g(x)=\dfrac{x+3}{6}[/tex] and the graphs of these functions are shown below.

how much must be added to 750 metres to make 2 km
Answer:
1250 meters because 2 km is 2000 meters
2000 - 750
= 1250
Answer:
you need to add 1250 to 750 in order to make 2 km
Step-by-step explanation:
We know that:
1 KM = 1000 meters
and out of those 1000, we already have 750, therefore:
1000-750 = 250
Which completes 1 km now, since there are 2 km, add 1000 to 250:
1000+250 = 1250
So you need to add 1250 meters to make 2 km

What is a polygon?A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments is referred to as its edges or sides.
An octagon has 8 sides.
We know, Apothm is the distance from the center to its side.
We also know that an octagon can be divided into 8 similar triangles.
Therefore, The area of the octagon will be,
= 8×(1/2)×3×3.5 square feet.
= 4×10.5 square feet.
= 42 square feet.
