Answer:
K = 12
Step-by-step explanation:
10 Cos 30° – 3 Tan 60°
The above expression can be simplified as follow:
10 Cos 30° – 3 Tan 60°
Recall:
Cos 30° = √3/2
Tan 60° = √3
Therefore,
10 Cos 30° – 3 Tan 60°
10 (√3/2) – 3(√3)
5√3 – 3√3
(5 – 3) √3
2√3
To write the above expression 2√3 in the form √K, we simply do the following:
2√3
Find a number, such that the square root of the number will result to 2. The number is 4 as shown below
√4 = 2
Next, replace 2 with √4 in the expression above
2√3
= √4 × √3
= √(4 × 3)
= √12
Therefore,
2√3 = √12
Comparing √12 with √K,
√12 = √K
K = 12
Answer:
Step-by-step explanation:
#6. correct
#7. 3 3/4 - 1 7/8 = 1 7/8
#8. correct
#9. 3 3/8 + 3 3/4 = 7 1/8
#10. 19 - 16 7/8 = 2 1/8
All results in pounds.
I do but it's really hard to explain
