Answer:
A. $1500.00
Step-by-step explanation:
Assuming this is a simple interest savings account.
<u>Simple interest formula</u>
I = Prt
where:
- I = total interest
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- I = $225
- r = 3% = 0.03
- t = 5 years
Substitute the given values into the formula and solve for P:
⇒ I = Prt
⇒ 225 = P(0.03 ×5)
⇒ 225 = P(0.15)
⇒ P = 225 ÷ 0.15
⇒ P = 1500
Therefore, Timothy started the account with $1500.00.
Answer:
r =5 in
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We know the area and pi
78.5 = 3.14 r^2
Divide by 3.14
78.5/3.14 = 3.14 /3.14 r^2
25 = r^2
Take the square root of each side
sqrt(25) = sqrt(r^2)
5=r
To know if p = -1 is a possible solution to <span>6(p – 4) = -30p, plug in -1 for p and see if the equation is true.
</span><span>6(p – 4) = -30p
</span><span>6(-1 – 4) = -30(-1)
</span>6(-1 – 4) = -30(-1)<span>
Solve the parentheses.
-1 - 4 = -5
</span>6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30
-30 = 30
This is not true, so p = -1 is NOT a possible solution for the <span>equation 6(p – 4) = -30p.
Hope this helps!</span>
