Answer: 43.3 inches.
Step-by-step explanation:
According to the Pythagorean Theorem:
Where "a" is the hypotenuse, and "b" and "c" are the legs of the right triangle.
Let be "c" the width of the television.
We can indentify in the figure that:
Then, we can substitute values and solve for "c":
Rounded to the nearest tenth:
1) 9.1 = -0.2x + 10 | - 10
9.1 - 10 = -0,2x + 10 - 10
-0.9 = -0.2x | × 10
-0.9 × 10 = -0.2x × 10
-9 = -2x | ÷ (-2)
-9 ÷ (-2) = -2x ÷ (-2)
9/2 = x
x = 4.5
2) 10 = 9.1 + 0.2x | - 9.1
10 - 9.1 = 9.1 + 0.2x - 0.9
0.9 = 0.2x | × 10
0.9 × 10 = 0.2x × 10
9 = 2x | ÷ 2
9 ÷ 2 = 2x ÷ 2
9/2 = x
x = 4.5
3) 10 - 0.2x = 9.1 | - 10
-0.2x = -0.9 | × 10
-2x = -9 | ÷ (-2)
x = 9/2
x = 4.5
4) 9.1 - 10 = 0.2x
-0.9 = 0.2x | × 10
-9 = 2x | ÷ 2
-9/2 = x
x = -4.5
Answer: The last one equation gives a different value of x.
Answer:
1) 2.71%
2) $38.32
Step-by-step explanation:
Opening balance = $1220
Balance after 10 days (after expense) = $1690
Balance after 10 days(after payment) = $1340
APR = 33%
1) Periodic interest rate = APR ×
= 33%× 30/365
= 2.71%
2) Interest charged for first 10 days =
= $11.02
Interst charged for the next 10 days =
= $15.2
Interest charged for the next 10 days =
= $12.10
Total interest for 30 days = 11.02+15.2+12.10
= $38.32
