Answer:
n = 24
Step-by-step explanation:
(n + 18) and 2n are "complementary angles:" they add up to 90°.
Thus, n + 18 + 2n = 90. Combining the n terms results in 3n + 18 = 90.
Then 3n = 72. Dividing both sides by 3 results in n = 24.
n is 24, so n + 18 is 42 and 2n is 48. Note that 42 and 48 add up to 90.
We have to identify the given object.
A. Cube: The given object is not a cube because cube is a box-shaped solid object that has six identical square faces. But here, the given figure does not have the identical faces.
B. Polygon: The given object is not a polygon because a polygon is any 2-dimensional shape formed with line segments. But here, the given figure is not 2-dimensional.
C. Polyhedron: The given object is a polyhedron because a polyhedron is a solid in three dimensions with flat polygonal faces, straight edges and sharp corners or vertices. Therefore, it is a polyhedron.
D. Prism: The given object is a prism because a prism is a polyhedron consisting of two parallel, congruent faces called bases. This is called a rectangular prism because a Prism with rectangular bases is a Rectangular Prism.
E. Pyramid: The given object is not a pyramid because a pyramid is a 3-dimensional shape whose base is a polygon. Each corner of a polygon is attached to a singular apex, which gives the pyramid its distinctive shape. Each base edge and the apex form a triangle. The given object does not appears like this.
So, the given object is Polyhedron and Prism(rectangular).
There are 52 weeks in one year and Flora records her pet hamsters weight once every week for one year, so she recored 52 weight observations.
Simple interest formula is
I=P*(rt)
P=70
t=12
3%=0.03
r=0.03
I = 70*0.03*12= 25.2
Answer: 4
Step-by-step explanation:
( f o g ) (3) means f(g(3)) so...
First: plug 3 into g(x) = x^ (2-1)
3^ (2-1) is 3^1 = 3
Next: plug 3 into f(x)= 2^(x-1)
2^(3-1) is 2^(2) > 2×2 = 4
