Answer:
=250(1.025)∧4t
Step-by-step explanation:
Using the compound interest formula we can find the expression for the total amount that accumulates in the given time t.
A=P(1+R/n)ⁿᵇ
where A is the amount, P the principal amount, R the rate as a decimal n is the number of times it is compounded and b the time.
When compounded annually, the expression becomes
A=250(1.1)∧t
When compounded quarterly, we introduce the n in our expression.
A=250(1+0.1/4)∧4t
=250(1.025)∧4t
Answer:
3 * (x + 7)
Step-by-step explanation:
Mark number as x
Then the sum of a number and seven is x + 7
Three times x + 7 can be written as
3 * (x + 7)
Parentheses mean that we first add x and 7 and then multiply their sum by 3
Alternatively you can write it as 3x + 21, since
3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21
Answer:
r=7v−12
Step-by-step explanation:
Let's solve for r.
−8−2r=−7v−7v+16
Step 1: Add 8 to both sides.
−2r−8+8=−14v+16+8
−2r=−14v+24
Step 2: Divide both sides by -2.
−2r
−2
=
−14v+24
−2
r=7v−12
