Answer:
2 %
Step-by-step explanation:
Money borrowed, Principal, P = $ 700
time of investment, T = 3 years
Total interest paid, Simple interest, S.I = $ 42
Let the rate of interest is R.
Use the formula for simple interest.
By substituting the values
4200 = 2100 R
R = 2 %
Thus, the rate of interest is 2%.

Answer: 2/3</h3>
===========================================================
Explanation:
set A = dice values greater than 4 = {5,6}
set B = dice values 4 or less = {1,2,3,4}
Sets A and B are considered complementary because one or the other must happen. You must either roll something larger than 4 (set A) or you must roll something from set B.
There are 4 items in set B out of 6 possible outcomes. That leads us to the answer 4/6 = 2/3
Answer:
For x = 1, y = 2× 1² y =
= 2 × 1 = 2
= 2
For x = 2, y = 2× 2² y = 2²
= 2 × 4 = 4
= 8
Answer:
Equation: (5x + 20) + (3x - 30) + (2x + 10) + 8x = 360
x = 20
Angle B = 30°
Step-by-step explanation:
Given:
<A = 5x + 20
<B = 3x - 30
<C = 2x + 10
<D = 8x
Sum of interior angles of a quadrilateral = 360°
Therefore:
<A + <B + <C + <D = 360°
(5x + 20) + (3x - 30) + (2x + 10) + 8x = 360
Solve for x
5x + 20 + 3x - 30 + 2x + 10 + 8x = 360
Collect like terms
5x + 3x + 2x + 8x + 20 - 30 + 10 = 360
18x = 360
Divide both sides by 18
x = 360/18
x = 20
<B = 3x - 30
Plug in the value of x
<B = 3(20) - 30 = 60 - 30
<B = 30°
