Answer:
Interest rate, R = 244%
Step-by-step explanation:
Given the following data;
Principal = $270
Simple interest = future amount - principal = 309.60 - 270 = $39.60
Time = 22/360 = 0.06 years
To find the interest rate?
Mathematically, simple interest is calculated using this formula;

Where;
Substituting into the equation, we have;
Cross-multiplying, we have;
<em>Interest rate, R = 244.44 ≈ 244%</em>
<em>Therefore, the pawnbroker charged Elisa a simple interest rate of 244%.</em>
Angles in a triangle must add up to 180, so the missing angle inside the triangle is 180 - (70 + 40), which is 70.
Angles on a straight line (i.e. the line BD) must add up to 180, and because we know part of that angle is 70, x must be 180 - 70, which is 110.
Hence, x is 110 degrees.
Answer:
A. U - 2v = -14i +13j
Step-by-step explanation:
If u = (-2, 5) and v = 6i -4j
Then 2v = 2*(6i-4j) = 12i-8j
u-2v = -2i +5j - (6i -4j)
Distribute the minus sign
-2i +5j -6i+4j
-2i +5j
-12i + 8j
---------------
-14i +13j

Answer:
no
Step-by-step explanation:
if the ratio (yx) of two variables (x and y) is equal to a constant (k=yx) .in this case y is said to be directly proportional to x with proportionality constant k
