Answer:

<h3>\boxed{ \boxed{ \bold{ \purple{y = 4}}}}</h3>

Step-by-step explanation:

\sf{Given}

\sf{d = 7}

Let's find the value of y:

\sf{y =  \frac{1}{2} (d + 1)}

plug the value of d

\sf{ =  \frac{1}{2} (7 + 1)}

Add the numbers

\sf{= \frac{1}{2}  \times 8}

Calculate

\sf{ = 4}

Hope I helped!

Best regards!

How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%
erik [133]
Answer:
A = $ 2,120.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation

A = 2000(1 + (0.03 × 2)) = 2120 
A = $ 2,120.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 2,000.00
at a rate of 3% per year
for 2 years is $ 2,120.00.

Can someone please help me answer this
Alexus [3.1K]

Answer:

1) a = 1.6          2) f = 0.53

Step-by-step explanation:

1) 6a = 10                      2) 48 = 90f

6a/6 = 10/6                       90f/90 = 48/90

a = 1.6                                f = 0.53

sorry i could only do the first two, i think those are right
