Answer:
B = 13
Step-by-step explanation:
The tangent and cotangent are equal when the angles are complementary.
(3B +35) +(2B -10) = 90
5B = 65
B = 13
___
<em>Check</em>
For B=13, the angles are 3B+35 = 39+35 = 74, and 2B-10 = 26-10 = 16. Both are acute angles.
Answer:

Step-by-step explanation:
There are 6 reading groups
24 students ÷ 4 students each group= 6 reading groups
For simple interest, the formula is I = PRT, where I = interest, P = principal borrowed or deposited, R = rate as a decimal, and T = time in years.
Your information:
I = (870)(0.08)(5)
I = 348
Add the interest to the principal for your total balance
348 + 870 = $1218 will be the total balance in the account.
