Answer: 56.0°
<u>Step-by-step explanation:</u>
Use the Law of Cosines:
b² = a² + c² - 2ac · cos B
20² = 22² + 18² - 2(22)(18) · cos B
400 = 484 + 324 - 792 · cos B
400 = 804 - 792 · cos B
-404 = - 792 · cos B
0.5151 = cos B
cos ⁻¹ (0.5151) = B
55.99 = B
56.0 ≈ B

Answer: $6, 720
Step-by-step explanation:
Formular for simple interest =P×R×T
where;
P= 6000
R= 3% = 0.03
T= 4 years
$6000 × 0.03 × 4
= $720
The total amount to be paid back at the end of time will be
$6,000 + $720
=$6, 720
I hope this helps
Answer:
x+7 ≤ 20
Just take it step by step:
seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.
it then says it's equal to at most 20.
This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals
x+7≤ 20
≤ -this symbol means less than or equal to
