Answer:
x ≈ 8.3 ( to the nearest tenth )
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos41° = 
= 
= 
Multiply both sides by 11
11 × cos41° = x, thus
x ≈ 8.3
Answer:
33
Step-by-step explanation:
For every 5 squares, two are red and three are green. So 3/5 of the squares are green.
3/5x55=33
Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ￮ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2

Answer:
255
Step-by-step explanation:
If the sum of digits is 12, the number is divisible by 3. If the number ends in 0 or 5, it is divisible by 5. So, we're looking for ...
2x0 . . . where x is a digit and 2+x+0 = 12 . . . . . . not possible
2x5 . . . where x is a digit and 2+x+5 = 12 . . . . true for x=5
The number is 255.
15000 * (1+ 0.03)^4
15000 *1.1255 = 16882.63 total after 4 years
16882.63 - 15000 = 1882.63 total interest
Answer is D
