4 + 3 + 2 = 9
18/9 = 2
3 x 2 = 6
Answer = 6
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° =
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
69 is the correct answer
460 divided by 100 times 15 = 69
Answer:
1/6 of the third workers time
Step-by-step explanation:
one of the people is budgeted for 1 /2 of his time to the project and a second person for 1/3 of her time
Let x be the third workers time
Let the completed job time = 1
Time taken for 3 workers to complete the job = 1

now we solve for x
LCD = 2*3 = 6
We multiply the whole equation by 6

3 + 2 +6x = 6
5 + 6x = 6
subtract 5 on both sides
6x = 1
divide both sides by 6
