Answer:
I live in south Africa so my answer is 280.14
Step-by-step explanation:
7.5 over 100 times by 648.50 (thats how much $10.000 is in south Africa)
=46.69 times by 6
=280.14
Answer:
C
Step-by-step explanation:
The Principal is the amount you deposit at the start, so P= $500
The rate is 7%, as you will be earning 7% extra yearly in simple interest.
As a decimal, the rate is 0.07 - 7 PER CENT literally means per 100, so 7/100 is 0.07. However, when actually figuring out the simple interest, you have to add 1 to 0.07 because you are earning 7% ON TOP OF your original amount.
The time is 10, as you are leaving the money in the account for 10 years, and time is measured in the given unit
Now, let's plug in this information into the general formulas:
I=Prt
where I is the just the interest earned
I=500×0.07×10
I=$350
A=P(1+r/100×t)
where A is the total amount (original sum of money plus interest)
A=500(1+0.07×10)
A=$850

Answer:
B. 3x^2 +11x -20 = 0
Step-by-step explanation:
For solutions p and q, the quadratic will be
(x -p)(x -q) = 0
We notice that the leading coefficients of the offered answer choices are greater than 1, so it will be convenient to use a value that "clears fractions."
(x -4/3)(x -(-5)) = 0
3(x -4/3)(x +5) = 0 . . . . multiply by 3 to clear the fraction
(3x -4)(x +5) = 0 . . . . . . clear the fraction
3x(x +5) -4(x +5) = 0 . . use the distributive property
3x^2 +15x -4x -20 = 0 . . . . use the distributive property again
3x^2 +11x -20 = 0 . . . . collect terms
_____
The constant in the product of factors is the product of roots:
(x -p)(x -q) = x^2 -(p+q)x +pq
Here, that would mean the constant would be (4/3)(-5) = -20/3.
If we compare the above quadratic to the standard form:
ax^2 +bx +c = 0
we find that we can divide the standard form equation by 'a' to get ...
pq = c/a
That is, c/a = -20/3, so we might start looking for an answer choice that has a leading coefficient of a=3 and a constant of c=-20.
