Solve the following problem. linda can complete 4.5 long divisions in 1 hour. how many can she finish in 6.5 hours? a. 11 b. 29.25 c. 2 d. 0.69

Option B. 29.25

Step-by-step explanation:

Linda can complete 4.5 long divisions in 1 hour.

We have to calculate the number of long divisions she can finish in 6.5 hours.

We will solve this by unitary method.

∵ in 1 hour she can complete = 4.5 long divisions.

∴ in 6.5 hours she can complete = 4.5 × 6.5

                                                      = 29.25

29.25 long divisions she can complete in 6.5 hours.

Option B.

7

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
