Answer:
The number of different ways the car can be built is 31 different ways
Step-by-step explanation:
The given options are'
1), Leather seats, 2) Heated seats, 3) Sunroof, 4) Tinted windows, 5), back up camera
Therefore, the number of different ways the car can be built, n, is given as follows;
n = ₅C₁ + ₅C₂ + ₅C₃ + ₅C₄ + ₅C₅
n = 5 + 10 + 10 + 5 + 1 = 31 different ways
The number of different ways the car can be built = n = 31 different ways
Answer:
x = 20 and y = 14.14213562 ( you can simplify it)
Step-by-step explanation
x = the opposite side divided by sin 45 ( the angle)
/ sin(45)
20
y = the opposite side divided by the adjacent side
/ tan(45)
14.14213562
14.14
Answer:
B
Step-by-step explanation:
The composite figure consists of a triangle and a semicircle.
The area (A) of the triangle is calculated as
A = 0. 5 bh ( b is the base and h the perpendicular height )
here b = 2 × 4 = 8 and h = 3, thus
A = 0.5 × 8 × 3 = 12 in²
The area (A) of the semicircle is calculated as
A = 0.5πr² ← r is the radius = 4, thus
A = 0.5π ×4² = 0.5 = 0.5π × 16 = 8π
Sum the 2 areas together for area of composite shape, that is
area of composite shape = ( 8π + 12 ) in² → B
