the answer should be
Step-by-step explanation:
Answer:
Please check the explanation.
Step-by-step explanation:
Using the formula
I = Prt
here
P = The principle
t = Time in years
I = Simple interest
r = Annual interest rate
Let us fill the table using the formula:
I = Prt
<u></u>
<u>ROW ONE</u><u>:</u>
Given
P = $100
r = 5% = 0.05
t = 3
Determine:
I = ?
Using the formula
I = Prt
I = 100 × 0.05 × 3
I = $15
<u>ROW TWO</u><u>:</u>
Given
P = $500
r = 4% = 0.04
I = $20
Determine:
t = ?
Using the formula
I = Prt
20 = Prt
20 = 500 × 0.04 × t
t = 20 / (500 × 0.04)
t = 20 / 20
t = 1 year
<u>ROW THREE</u><u>:</u>
Given
t = 7
r = 10% = 0.1
I = $35
Determine:
P = ?
Using the formula
I = Prt
35 = P(0.1) (7)
P = 35 / (0.1×7)
P = $50
<u>ROW FOUR</u><u>:</u>
Given
P = $200
t = 2 years
I = $6
Determine:
r = ?
Using the formula
I = Prt
6 = 200 × r × 2
r = 6 / (200×2)
r = 6 / 400
t = 0.015
t = 1.5% ∵ 1.5% = 0.015
Answer: B = 56 degrees
Step-by-step explanation: Complementary angles add up 90 degrees. So we will set both of the equations equal to 90 degrees and then solve from there.
6x+8+5x+21=90
1. Simplify 5x + 6x and 21 - 8
11x+13=90
2. Subtract 13 from both sides.
11x=90-13
3. Simplify 90-13 to 77.
11x=77
4. Divide both sides by 11.
x = 77/11
5. Simplify 77/11 to 7
x=7
Now we have to take the value of x and substitute it back into B = (5x+21)
1. Substitute
B = (5(7)+21)
B = 35 +21
B = 56
